INTRODUCTION


As I look back now on the sensational events of the past months since
the great European War began, it seems to me as if there had never been
a period in Craig Kennedy's life more replete with thrilling adventures
than this.

In fact, scarcely had one mysterious event been straightened out from
the tangled skein, when another, even more baffling, crowded on its
very heels.

As was to have been expected with us in America, not all of these
remarkable experiences grew either directly or indirectly out of the
war, but there were several that did, and they proved to be only the
beginning of a succession of events which kept me busy chronicling for
the Star the exploits of my capable and versatile friend.

Altogether, this period of the war was, I am sure, quite the most
exciting of the many series of episodes through which Craig has been
called upon to go. Yet he seemed to meet each situation as it arose
with a fresh mind, which was amazing even to me who have known him so
long and so intimately.

As was naturally to be supposed, also, at such a time, it was not long
before Craig found himself entangled in the marvelous spy system of the
warring European nations. These systems revealed their devious and dark
ways, ramifying as they did tentacle-like even across the ocean in
their efforts to gain their ends in neutral America. Not only so, but,
as I shall some day endeavor to show later, when the ban of silence
imposed by neutrality is raised after the war, many of the horrors of
the war were brought home intimately to us.

I have, after mature consideration, decided that even at present
nothing but good can come from the publication at least of some part of
the strange series of adventures through which Kennedy and I have just
gone, especially those which might, if we had not succeeded, have
caused most important changes in current history. As for the other
adventures, no question can be raised about the propriety of their
publication.

At any rate, it came about that early in August, when the war cloud was
just beginning to loom blackest, Kennedy was unexpectedly called into
one of the strangest, most dangerous situations in which his peculiar
and perilous profession had ever involved him.



CHAPTER I

THE WAR TERROR


"I must see Professor Kennedy--where is he?--I must see him, for God's
sake!"

I was almost carried off my feet by the inrush of a wild-eyed girl,
seemingly half crazed with excitement, as she cried out Craig's name.

Startled by my own involuntary exclamation of surprise which followed
the vision that shot past me as I opened our door in response to a
sudden, sharp series of pushes at the buzzer, Kennedy bounded swiftly
toward me, and the girl almost flung herself upon him.

"Why, Miss--er--Miss--my dear young lady--what's the matter?" he
stammered, catching her by the arm gently.

As Kennedy forced our strange visitor into a chair, I observed that she
was all a-tremble. Her teeth fairly chattered. Alternately her nervous,
peaceless hands clutched at an imaginary something in the air, as if
for support, then, finding none, she would let her wrists fall supine,
while she gazed about with quivering lips and wild, restless eyes.
Plainly, there was something she feared. She was almost over the verge
of hysteria.

She was a striking girl, of medium height and slender form, but it was
her face that fascinated me, with its delicately molded features,
intense unfathomable eyes of dark brown, and lips that showed her
idealistic, high-strung temperament.

"Please," he soothed, "get yourself together, please--try! What is the
matter?"

She looked about, as if she feared that the very walls had eyes and
ears. Yet there seemed to be something bursting from her lips that she
could not restrain.

"My life," she cried wildly, "my life is at stake. Oh--help me, help
me! Unless I commit a murder to-night, I shall be killed myself!"

The words sounded so doubly strange from a girl of her evident
refinement that I watched her narrowly, not sure yet but that we had a
plain case of insanity to deal with.

"A murder?" repeated Kennedy incredulously. "YOU commit a murder?"

Her eyes rested on him, as if fascinated, but she did not flinch as she
replied desperately, "Yes--Baron Kreiger--you know, the German diplomat
and financier, who is in America raising money and arousing sympathy
with his country."

"Baron Kreiger!" exclaimed Kennedy in surprise, looking at her more
keenly.

We had not met the Baron, but we had heard much about him, young,
handsome, of an old family, trusted already in spite of his youth by
many of the more advanced of old world financial and political leaders,
one who had made a most favorable impression on democratic America at a
time when such impressions were valuable.

Glancing from one of us to the other, she seemed suddenly, with a great
effort, to recollect herself, for she reached into her chatelaine and
pulled out a card from a case.

It read simply, "Miss Paula Lowe."

"Yes," she replied, more calmly now to Kennedy's repetition of the
Baron's name, "you see, I belong to a secret group." She appeared to
hesitate, then suddenly added, "I am an anarchist."

She watched the effect of her confession and, finding the look on
Kennedy's face encouraging rather than shocked, went on breathlessly:
"We are fighting war with war--this iron-bound organization of men and
women. We have pledged ourselves to exterminate all kings, emperors and
rulers, ministers of war, generals--but first of all the financiers who
lend money that makes war possible."

She paused, her eyes gleaming momentarily with something like the
militant enthusiasm that must have enlisted her in the paradoxical war
against war.

"We are at least going to make another war impossible!" she exclaimed,
for the moment evidently forgetting herself.

"And your plan?" prompted Kennedy, in the most matter-of-fact manner,
as though he were discussing an ordinary campaign for social
betterment. "How were you to--reach the Baron?"

"We had a drawing," she answered with amazing calmness, as if the mere
telling relieved her pent-up feelings. "Another woman and I were
chosen. We knew the Baron's weakness for a pretty face. We planned to
become acquainted with him--lure him on."

Her voice trailed off, as if, the first burst of confidence over, she
felt something that would lock her secret tighter in her breast.

A moment later she resumed, now talking rapidly, disconnectedly, giving
Kennedy no chance to interrupt or guide the conversation.

"You don't know, Professor Kennedy," she began again, "but there are
similar groups to ours in European countries and the plan is to strike
terror and consternation everywhere in the world at once. Why, at our
headquarters there have been drawn up plans and agreements with other
groups and there are set down the time, place, and manner of all
the--the removals."

Momentarily she seemed to be carried away by something like the
fanaticism of the fervor which had at first captured her, even still
held her as she recited her incredible story.

"Oh, can't you understand?" she went on, as if to justify herself. "The
increase in armies, the frightful implements of slaughter, the total
failure of the peace propaganda--they have all defied civilization!

"And then, too, the old, red-blooded emotions of battle have all been
eliminated by the mechanical conditions of modern warfare in which men
and women are just so many units, automata. Don't you see? To fight war
with its own weapons--that has become the only last resort."

Her eager, flushed face betrayed the enthusiasm which had once carried
her into the "Group," as she called it. I wondered what had brought her
now to us.

"We are no longer making war against man," she cried. "We are making
war against picric acid and electric wires!"

I confess that I could not help thinking that there was no doubt that
to a certain type of mind the reasoning might appeal most strongly.

"And you would do it in war time, too?" asked Kennedy quickly.

She was ready with an answer. "King George of Greece was killed at the
head of his troops. Remember Nazim Pasha, too. Such people are easily
reached in time of peace and in time of war, also, by sympathizers on
their own side. That's it, you see--we have followers of all
nationalities."

She stopped, her burst of enthusiasm spent. A moment later she leaned
forward, her clean-cut profile showing her more earnest than before.
"But, oh, Professor Kennedy," she added, "it is working itself out to
be more terrible than war itself!"

"Have any of the plans been carried out yet?" asked Craig, I thought a
little superciliously, for there had certainly been no such wholesale
assassination yet as she had hinted at.

She seemed to catch her breath. "Yes," she murmured, then checked
herself as if in fear of saying too much. "That is, I--I think so."

I wondered if she were concealing something, perhaps had already had a
hand in some such enterprise and it had frightened her.

Kennedy leaned forward, observing the girl's discomfiture. "Miss Lowe,"
he said, catching her eye and holding it almost hypnotically, "why have
you come to see me?"

The question, pointblank, seemed to startle her. Evidently she had
thought to tell only as little as necessary, and in her own way. She
gave a little nervous laugh, as if to pass it off. But Kennedy's eyes
conquered.

"Oh, can't you understand yet?" she exclaimed, rising passionately and
throwing out her arms in appeal. "I was carried away with my hatred of
war. I hate it yet. But now--the sudden realization of what this
compact all means has--well, caused something in me to--to snap. I
don't care what oath I have taken. Oh, Professor Kennedy, you--you must
save him!"

I looked up at her quickly. What did she mean? At first she had come to
be saved herself. "You must save him!" she implored.

Our door buzzer sounded.

She gazed about with a hunted look, as if she felt that some one had
even now pursued her and found out.

"What shall I do?" she whispered. "Where shall I go?"

"Quick--in here. No one will know," urged Kennedy, opening the door to
his room. He paused for an instant, hurriedly. "Tell me--have you and
this other woman met the Baron yet? How far has it gone?"

The look she gave him was peculiar. I could not fathom what was going
on in her mind. But there was no hesitation about her answer. "Yes,"
she replied, "I--we have met him. He is to come back to New York from
Washington to-day--this afternoon--to arrange a private loan of five
million dollars with some bankers secretly. We were to see him
to-night--a quiet dinner, after an automobile ride up the Hudson--"

"Both of you?" interrupted Craig.

"Yes--that--that other woman and myself," she repeated, with a peculiar
catch in her voice. "To-night was the time fixed in the drawing for
the--"

The word stuck in her throat. Kennedy understood. "Yes, yes," he
encouraged, "but who is the other woman?"

Before she could reply, the buzzer had sounded again and she had
retreated from the door. Quickly Kennedy closed it and opened the
outside door.

It was our old friend Burke of the Secret Service.

Without a word of greeting, a hasty glance seemed to assure him that
Kennedy and I were alone. He closed the door himself, and, instead of
sitting down, came close to Craig.

"Kennedy," he blurted out in a tone of suppressed excitement, "can I
trust you to keep a big secret?"

Craig looked at him reproachfully, but said nothing.

"I beg your pardon--a thousand times," hastened Burke. "I was so
excited, I wasn't thinking--"

"Once is enough, Burke," laughed Kennedy, his good nature restored at
Burke's crestfallen appearance.

"Well, you see," went on the Secret Service man, "this thing is so very
important that--well, I forgot."

He sat down and hitched his chair close to us, as he went on in a
lowered, almost awestruck tone.

"Kennedy," he whispered, "I'm on the trail, I think, of something
growing out of these terrible conditions in Europe that will tax the
best in the Secret Service. Think of it, man. There's an organization,
right here in this city, a sort of assassin's club, as it were, aimed
at all the powerful men the world over. Why, the most refined and
intellectual reformers have joined with the most red-handed anarchists
and--"

"Sh! not so loud," cautioned Craig. "I think I have one of them in the
next room. Have they done anything yet to the Baron?"

It was Burke's turn now to look from one to the other of us in
unfeigned surprise that we should already know something of his secret.

"The Baron?" he repeated, lowering his voice. "What Baron?"

It was evident that Burke knew nothing, at least of this new plot which
Miss Lowe had indicated. Kennedy beckoned him over to the window
furthest from the door to his own room.

"What have you discovered?" he asked, forestalling Burke in the
questioning. "What has happened?"

"You haven't heard, then?" replied Burke.

Kennedy nodded negatively.

"Fortescue, the American inventor of fortescite, the new explosive,
died very strangely this morning."

"Yes," encouraged Kennedy, as Burke came to a full stop to observe the
effect of the information.

"Most incomprehensible, too," he pursued. "No cause, apparently. But it
might have been overlooked, perhaps, except for one thing. It wasn't
known generally, but Fortescue had just perfected a successful
electro-magnetic gun--powderless, smokeless, flashless, noiseless and
of tremendous power. To-morrow he was to have signed the contract to
sell it to England. This morning he is found dead and the final plans
of the gun are gone!"

Kennedy and Burke were standing mutely looking at each other.

"Who is in the next room?" whispered Burke hoarsely, recollecting
Kennedy's caution of silence.

Kennedy did not reply immediately. He was evidently much excited by
Burke's news of the wonderful electro-magnetic gun.

"Burke," he exclaimed suddenly, "let's join forces. I think we are both
on the trail of a world-wide conspiracy--a sort of murder syndicate to
wipe out war!"

Burke's only reply was a low whistle that involuntarily escaped him as
he reached over and grasped Craig's hand, which to him represented the
sealing of the compact.

As for me, I could not restrain a mental shudder at the power that
their first murder had evidently placed in the hands of the anarchists,
if they indeed had the electro-magnetic gun which inventors had been
seeking for generations. What might they not do with it--perhaps even
use it themselves and turn the latest invention against society itself!

Hastily Craig gave a whispered account of our strange visit from Miss
Lowe, while Burke listened, open-mouthed.

He had scarcely finished when he reached for the telephone and asked
for long distance.

"Is this the German embassy in Washington?" asked Craig a few moments
later when he got his number. "This is Craig Kennedy, in New York. The
United States Secret Service will vouch for me--mention to them Mr.
Burke of their New York office who is here with me now. I understand
that Baron Kreiger is leaving for New York to meet some bankers this
afternoon. He must not do so. He is in the gravest danger if he--What?
He left last night at midnight and is already here?"

Kennedy turned to us blankly.

The door to his room opened suddenly.

There stood Miss Lowe, gazing wild-eyed at us. Evidently her
supernervous condition had heightened the keenness of her senses. She
had heard what we were saying. I tried to read her face. It was not
fear that I saw there. It was rage; it was jealousy.

"The traitress--it is Marie!" she shrieked.

For a moment, obtusely, I did not understand.

"She has made a secret appointment with him," she cried.

At last I saw the truth. Paula Lowe had fallen in love with the man she
had sworn to kill!



CHAPTER II

THE ELECTRO-MAGNETIC GUN


"What shall we do?" demanded Burke, instantly taking in the dangerous
situation that the Baron's sudden change of plans had opened up.

"Call O'Connor," I suggested, thinking of the police bureau of missing
persons, and reaching for the telephone.

"No, no!" almost shouted Craig, seizing my arm. "The police will
inevitably spoil it all. No, we must play a lone hand in this if we are
to work it out. How was Fortescue discovered, Burke?"

"Sitting in a chair in his laboratory. He must have been there all
night. There wasn't a mark on him, not a sign of violence, yet his face
was terribly drawn as though he were gasping for breath or his heart
had suddenly failed him. So far, I believe, the coroner has no clue and
isn't advertising the case."

"Take me there, then," decided Craig quickly. "Walter, I must trust
Miss Lowe to you on the journey. We must all go. That must be our
starting point, if we are to run this thing down."

I caught his significant look to me and interpreted it to mean that he
wanted me to watch Miss Lowe especially. I gathered that taking her was
in the nature of a third degree and as a result he expected to derive
some information from her. Her face was pale and drawn as we four piled
into a taxicab for a quick run downtown to the laboratory of Fortescue
from which Burke had come directly to us with his story.

"What do you know of these anarchists?" asked Kennedy of Burke as we
sped along. "Why do you suspect them?"

It was evident that he was discussing the case so that Paula could
overhear, for a purpose.

"Why, we received a tip from abroad--I won't say where," replied Burke
guardedly, taking his cue. "They call themselves the 'Group,' I
believe, which is a common enough term among anarchists. It seems they
are composed of terrorists of all nations."

"The leader?" inquired Kennedy, leading him on.

"There is one, I believe, a little florid, stout German. I think he is
a paranoiac who believes there has fallen on himself a divine mission
to end all warfare. Quite likely he is one of those who have fled to
America to avoid military service. Perhaps, why certainly, you must
know him--Annenberg, an instructor in economics now at the University?"

Craig nodded and raised his eyebrows in mild surprise. We had indeed
heard of Annenberg and some of his radical theories which had sometimes
quite alarmed the conservative faculty. I felt that this was getting
pretty close home to us now.

"How about Mrs. Annenberg?" Craig asked, recalling the clever young
wife of the middle-aged professor.

At the mere mention of the name, I felt a sort of start in Miss Lowe,
who was seated next to me in the taxicab. She had quickly recovered
herself, but not before I saw that Kennedy's plan of breaking down the
last barrier of her reserve was working.

"She is one of them, too," Burke nodded. "I have had my men out
shadowing them and their friends. They tell me that the Annenbergs hold
salons--I suppose you would call them that--attended by numbers of men
and women of high social and intellectual position who dabble in
radicalism and all sorts of things."

"Who are the other leaders?" asked Craig. "Have you any idea?"

"Some idea," returned Burke. "There seems to be a Frenchman, a tall,
wiry man of forty-five or fifty with a black mustache which once had a
military twist. There are a couple of Englishmen. Then there are five
or six Americans who seem to be active. One, I believe, is a young
woman."

Kennedy checked him with a covert glance, but did not betray by a
movement of a muscle to Miss Lowe that either Burke or himself
suspected her of being the young woman in question.

"There are three Russians," continued Burke, "all of whom have escaped
from Siberia. Then there is at least one Austrian, a Spaniard from the
Ferrer school, and Tomasso and Enrico, two Italians, rather heavily
built, swarthy, bearded. They look the part. Of course there are
others. But these in the main, I think, compose what might be called
'the inner circle' of the 'Group.'"

It was indeed an alarming, terrifying revelation, as we began to
realize that Miss Lowe had undoubtedly been telling the truth. Not
alone was there this American group, evidently, but all over Europe the
lines of the conspiracy had apparently spread. It was not a casual
gathering of ordinary malcontents. It went deeper than that. It
included many who in their disgust at war secretly were not unwilling
to wink at violence to end the curse. I could not but reflect on the
dangerous ground on which most of them were treading, shaking the basis
of all civilization in order to cut out one modern excrescence.

The big fact to us, just at present, was that this group had made
America its headquarters, that plans had been studiously matured and
even reduced to writing, if Paula were to be believed. Everything had
been carefully staged for a great simultaneous blow or series of blows
that would rouse the whole world.

As I watched I could not escape observing that Miss Lowe followed Burke
furtively now, as though he had some uncanny power.

Fortescue's laboratory was in an old building on a side street several
blocks from the main thoroughfares of Manhattan. He had evidently
chosen it, partly because of its very inaccessibility in order to
secure the quiet necessary for his work.

"If he had any visitors last night," commented Kennedy when our cab at
last pulled up before the place, "they might have come and gone
unnoticed."

We entered. Nothing had been disturbed in the laboratory by the coroner
and Kennedy was able to gain a complete idea of the case rapidly,
almost as well as if we had been called in immediately.

Fortescue's body, it seemed, had been discovered sprawled out in a big
armchair, as Burke had said, by one of his assistants only a few hours
before when he had come to the laboratory in the morning to open it.
Evidently he had been there undisturbed all night, keeping a gruesome
vigil over his looted treasure house.

As we gleaned the meager facts, it became more evident that whoever had
perpetrated the crime must have had the diabolical cunning to do it in
some ordinary way that aroused no suspicion on the part of the victim,
for there was no sign of any violence anywhere.

As we entered the laboratory, I noted an involuntary shudder on the
part of Paula Lowe, but, as far as I knew, it was no more than might
have been felt by anyone under the circumstances.

Fortescue's body had been removed from the chair in which it had been
found and lay on a couch at the other end of the room, covered merely
by a sheet. Otherwise, everything, even the armchair, was undisturbed.

Kennedy pulled back a corner of the sheet, disclosing the face,
contorted and of a peculiar, purplish hue from the congested blood
vessels. He bent over and I did so, too. There was an unmistakable odor
of tobacco on him. A moment Kennedy studied the face before us, then
slowly replaced the sheet.

Miss Lowe had paused just inside the door and seemed resolutely bound
not to look at anything. Kennedy meanwhile had begun a most minute
search of the table and floor of the laboratory near the spot where the
armchair had been sitting.

In my effort to glean what I could from her actions and expressions I
did not notice that Craig had dropped to his knees and was peering into
the shadow under the laboratory table. When at last he rose and
straightened himself up, however, I saw that he was holding in the palm
of his hand a half-smoked, gold-tipped cigarette, which had evidently
fallen on the floor beneath the table where it had burned itself out,
leaving a blackened mark on the wood.

An instant afterward he picked out from the pile of articles found in
Fortescue's pockets and lying on another table a silver cigarette case.
He snapped it open. Fortescue's cigarettes, of which there were perhaps
a half dozen in the case, were cork-tipped.

Some one had evidently visited the inventor the night before, had
apparently offered him a cigarette, for there were any number of the
cork-tipped stubs lying about. Who was it? I caught Paula looking with
fascinated gaze at the gold-tipped stub, as Kennedy carefully folded it
up in a piece of paper and deposited it in his pocket. Did she know
something about the case, I wondered?

Without a word, Kennedy seemed to take in the scant furniture of the
laboratory at a glance and a quick step or two brought him before a
steel filing cabinet. One drawer, which had not been closed as tightly
as the rest, projected a bit. On its face was a little typewritten card
bearing the inscription: "E-M GUN."

He pulled the drawer open and glanced over the data in it.

"Just what is an electro-magnetic gun?" I asked, interpreting the
initials on the drawer.

"Well," he explained as he turned over the notes and sketches, "the
primary principle involved in the construction of such a gun consists
in impelling the projectile by the magnetic action of a solenoid, the
sectional coils or helices of which are supplied with current through
devices actuated by the projectile itself. In other words, the sections
of helices of the solenoid produce an accelerated motion of the
projectile by acting successively on it, after a principle involved in
the construction of electro-magnetic rock drills and dispatch tubes.

"All projectiles used in this gun of Fortescue's evidently must have
magnetic properties and projectiles of iron or containing large
portions of iron are necessary. You see, many coils are wound around
the barrel of the gun. As the projectile starts it does so under the
attraction of those coils ahead which the current makes temporary
magnets. It automatically cuts off the current from those coils that it
passes, allowing those further on only to attract it, and preventing
those behind from pulling it back."

He paused to study the scraps of plans. "Fortescue had evidently also
worked out a way of changing the poles of the coils as the projectile
passed, causing them then to repel the projectile, which must have
added to its velocity. He seems to have overcome the practical
difficulty that in order to obtain service velocities with service
projectiles an enormous number of windings and a tremendously long
barrel are necessary as well as an abnormally heavy current beyond the
safe carrying capacity of the solenoid which would raise the
temperature to a point that would destroy the coils."

He continued turning over the prints and notes in the drawer. When he
finished, he looked up at us with an expression that indicated that he
had merely satisfied himself of something he had already suspected.

"You were right, Burke," he said. "The final plans are gone."

Burke, who, in the meantime, had been telephoning about the city in a
vain effort to locate Baron Kreiger, both at such banking offices in
Wall Street as he might be likely to visit and at some of the hotels
most frequented by foreigners, merely nodded. He was evidently at a
loss completely how to proceed.

In fact, there seemed to be innumerable problems--to warn Baron
Kreiger, to get the list of the assassinations, to guard Miss Lowe
against falling into the hands of her anarchist friends again, to find
the murderer of Fortescue, to prevent the use of the electro-magnetic
gun, and, if possible, to seize the anarchists before they had a chance
to carry further their plans.

"There is nothing more that we can do here," remarked Craig briskly,
betraying no sign of hesitation. "I think the best thing we can do is
to go to my own laboratory. There at least there is something I must
investigate sooner or later."

No one offering either a suggestion or an objection, we four again
entered our cab. It was quite noticeable now that the visit had shaken
Paula Lowe, but Kennedy still studiously refrained from questioning
her, trusting that what she had seen and heard, especially Burke's
report as to Baron Kreiger, would have its effect.

Like everyone visiting Craig's laboratory for the first time, Miss Lowe
seemed to feel the spell of the innumerable strange and uncanny
instruments which he had gathered about him in his scientific warfare
against crime. I could see that she was becoming more and more nervous,
perhaps fearing even that in some incomprehensible way he might read
her own thoughts. Yet one thing I did not detect. She showed no
disposition to turn back on the course on which she had entered by
coming to us in the first place.

Kennedy was quickly and deftly testing the stub of the little thin,
gold-tipped cigarette.

"Excessive smoking," he remarked casually, "causes neuroses of the
heart and tobacco has a specific affinity for the coronary arteries as
well as a tremendous effect on the vagus nerve. But I don't think this
was any ordinary smoke."

He had finished his tests and a quiet smile of satisfaction flitted
momentarily over his face. We had been watching him anxiously,
wondering what he had found.

As he looked up he remarked to us, with his eyes fixed on Miss Lowe,
"That was a ladies' cigarette. Did you notice the size? There has been
a woman in this case--presumably."

The girl, suddenly transformed by the rapid-fire succession of
discoveries, stood before us like a specter.

"The 'Group,' as anarchists call it," pursued Craig, "is the loosest
sort of organization conceivable, I believe, with no set membership, no
officers, no laws--just a place of meeting with no fixity, where the
comrades get together. Could you get us into the inner circle, Miss
Lowe?"

Her only answer was a little suppressed scream. Kennedy had asked the
question merely for its effect, for it was only too evident that there
was no time, even if she could have managed it, for us to play the
"stool pigeon."

Kennedy, who had been clearing up the materials he had used in the
analysis of the cigarette, wheeled about suddenly. "Where is the
headquarters of the inner circle?" he shot out.

Miss Lowe hesitated. That had evidently been one of the things she had
determined not to divulge.

"Tell me," insisted Kennedy. "You must!"

If it had been Burke's bulldozing she would never have yielded. But as
she looked into Kennedy's eyes she read there that he had long since
fathomed the secret of her wildly beating heart, that if she would
accomplish the purpose of saving the Baron she must stop at nothing.

"At--Maplehurst," she answered in a low tone, dropping her eyes from
his penetrating gaze, "Professor Annenberg's home--out on Long Island."

"We must act swiftly if we are to succeed," considered Kennedy, his
tone betraying rather sympathy with than triumph over the wretched girl
who had at last cast everything in the balance to outweigh the terrible
situation into which she had been drawn. "To send Miss Lowe for that
fatal list of assassinations is to send her either back into the power
of this murderous group and let them know that she has told us, or
perhaps to involve her again in the completion of their plans."

She sank back into a chair in complete nervous and physical collapse,
covering her face with her hands at the realization that in her
new-found passion to save the Baron she had bared her sensitive soul
for the dissection of three men whom she had never seen before.

"We must have that list," pursued Kennedy decisively. "We must visit
Annenberg's headquarters."

"And I?" she asked, trembling now with genuine fear at the thought that
he might ask her to accompany us as he had on our visit to Fortescue's
laboratory that morning.

"Miss Lowe," said Kennedy, bending over her, "you have gone too far now
ever to turn back. You are not equal to the trip. Would you like to
remain here? No one will suspect. Here at least you will be safe until
we return."

Her answer was a mute expression of thanks and confidence.



CHAPTER III

THE MURDER SYNDICATE


Quickly now Craig completed his arrangements for the visit to the
headquarters of the real anarchist leader. Burke telephoned for a
high-powered car, while Miss Lowe told frankly of the habits of
Annenberg and the chances of finding his place unguarded, which were
good in the daytime. Kennedy's only equipment for the excursion
consisted in a small package which he took from a cabinet at the end of
the room, and, with a parting reassurance to Paula Lowe, we were soon
speeding over the bridge to the borough across the river.

We realized that it might prove a desperate undertaking, but the crisis
was such that it called for any risk.

Our quest took us to a rather dilapidated old house on the outskirts of
the little Long Island town. The house stood alone, not far from the
tracks of a trolley that ran at infrequent intervals. Even a hasty
reconnoitering showed that to stop our motor at even a reasonable
distance from it was in itself to arouse suspicion.

Although the house seemed deserted, Craig took no chances, but directed
the car to turn at the next crossroad and then run back along a road
back of and parallel to that on which Annenberg's was situated. It was
perhaps a quarter of a mile away, across an open field, that we stopped
and ran the car up along the side of the road in some bushes.
Annenberg's was plainly visible and it was not at all likely that
anyone there would suspect trouble from that quarter.

A hasty conference with Burke followed, in which Kennedy unwrapped his
small package, leaving part of its contents with him, and adding
careful instructions.

Then Kennedy and I retraced our steps down the road, across by the
crossroad, and at last back to the mysterious house.

To all appearance there had been no need of such excessive caution. Not
a sound or motion greeted us as we entered the gate and made our way
around to the rear of the house. The very isolation of the house was
now our protection, for we had no inquisitive neighbors to watch us for
the instant when Kennedy, with the dexterity of a yeggman, inserted his
knife between the sashes of the kitchen window and turned the catch
which admitted us.

We made our way on cautious tiptoe through a dining room to a living
room, and, finding nothing, proceeded upstairs. There was not a soul,
apparently, in the house, nor in fact anything to indicate that it was
different from most small suburban homes, until at last we mounted to
the attic.

It was finished off in one large room across the back of the house and
two in front. As we opened the door to the larger room, we could only
gaze about in surprise. This was the rendezvous, the arsenal, literary,
explosive and toxicological of the "Group." Ranged on a table were all
the materials for bomb-making, while in a cabinet I fancied there were
poisons enough to decimate a city.

On the walls were pictures, mostly newspaper prints, of the assassins
of McKinley, of King Humbert, of the King of Greece, of King Carlos and
others, interspersed with portraits of anarchist and anti-militarist
leaders of all lands.

Kennedy sniffed. Over all I, too, could catch the faint odor of stale
tobacco. No time was to be lost, however, and while Craig set to work
rapidly going through the contents of a desk in the corner, I glanced
over the contents of a drawer of a heavy mission table.

"Here's some of Annenberg's literature," I remarked, coming across a
small pile of manuscript, entitled "The Human Slaughter House."

"Read it," panted Kennedy, seeing that I had about completed my part of
the job. "It may give a clue."

Hastily I scanned the mad, frantic indictment of war, while Craig
continued in his search:

"I see wild beasts all around me, distorted unnaturally, in a life and
death struggle, with bloodshot eyes, with foaming, gnashing mouths.
They attack and kill one another and try to mangle each other. I leap
to my feet. I race out into the night and tread on quaking flesh, step
on hard heads, and stumble over weapons and helmets. Something is
clutching at my feet like hands, so that I race away like a hunted deer
with the hounds at his heels--and ever over more bodies--breathless...
out of one field into another. Horror is crooning over my head. Horror
is crooning beneath my feet. And nothing but dying, mangled flesh!

"Of a sudden I see nothing but blood before me. The heavens have opened
and the red blood pours in through the windows. Blood wells up on an
altar. The walls run blood from the ceiling to the floor and... a giant
of blood stands before me. His beard and his hair drip blood. He seats
himself on the altar and laughs from thick lips. The black executioner
raises his sword and whirls it above my head. Another moment and my
head will roll down on the floor. Another moment and the red jet will
spurt from my neck.

"Murderers! Murderers! None other than murderers!"

I paused in the reading. "There's nothing here," I remarked, glancing
over the curious document for a clue, but finding none.

"Well," remarked Craig contemplatively, "one can at least easily
understand how sensitive and imaginative people who have fallen under
the influence of one who writes in that way can feel justified in
killing those responsible for bringing such horrors on the human race.
Hello--what's this?"

He had discovered a false back of one of the drawers in the desk and
had jimmied it open. On the top of innumerable papers lay a large linen
envelope. On its face it bore in typewriting, just like the card on the
drawer at Fortescue's, "E-M GUN."

"It is the original envelope that contained the final plans of the
electro-magnetic gun," he explained, opening it.

The envelope was empty. We looked at each other a moment in silence.
What had been done with the plans?

Suddenly a bell rang, startling me beyond measure. It was, however,
only the telephone, of which an extension reached up into the
attic-arsenal. Some one, who did not know that we were there, was
evidently calling up.

Kennedy quickly unhooked the receiver with a hasty motion to me to be
silent.

"Hello," I heard him answer. "Yes, this is it."

He had disguised his voice. I waited anxiously and watched his face to
gather what response he received.

"The deuce!" he exclaimed, with his hand over the transmitter so that
his voice would not be heard at the other end of the line.

"What's the matter?" I asked eagerly.

"It was Mrs. Annenberg--I am sure. But she was too keen for me. She
caught on. There must be some password or form of expression that they
use, which we don't know, for she hung up the receiver almost as soon
as she heard me."

Kennedy waited a minute or so. Then he whistled into the transmitter.
It was done apparently to see whether there was anyone listening. But
there was no answer.

"Operator, operator!" he called insistently, moving the hook up and
down. "Yes, operator. Can you tell me what number that was which just
called?"

He waited impatiently.

"Bleecker--7l80," he repeated after the girl. "Thank you. Information,
please."

Again we waited, as Craig tried to trace the call up.

"What is the street address of Bleecker, 7180?" he asked. "Five hundred
and one East Fifth--a tenement. Thank you."

"A tenement?" I repeated blankly.

"Yes," he cried, now for the first time excited. "Don't you begin to
see the scheme? I'll wager that Baron Kreiger has been lured to New
York to purchase the electro-magnetic gun which they have stolen from
Fortescue and the British. That is the bait that is held out to him by
the woman. Call up Miss Lowe at the laboratory and see if she knows the
place."

I gave central the number, while he fell to at the little secret drawer
of the desk again. The grinding of the wheels of a passing trolley
interfered somewhat with giving the number and I had to wait a moment.

"Ah--Walter--here's the list!" almost shouted Kennedy, as he broke open
a black-japanned dispatch box in the desk.

I bent over it, as far as the slack of the telephone wire of the
receiver at my ear would permit. Annenberg had worked with amazing care
and neatness on the list, even going so far as to draw at the top, in
black, a death's head. The rest of it was elaborately prepared in
flaming red ink.

Craig gasped to observe the list of world-famous men marked for
destruction in London, Paris, Berlin, Rome, Vienna, St. Petersburg, and
even in New York and Washington.

"What is the date set?" I asked, still with my ear glued to the
receiver.

"To-night and to-morrow," he replied, stuffing the fateful sheet into
his pocket.

Rummaging about in the drawer of the table, I had come to a package of
gold-tipped cigarettes which had interested me and I had left them out.
Kennedy was now looking at them curiously.

"What is to be the method, do you suppose?" I asked.

"By a poison that is among the most powerful, approaching even
cyanogen," he replied confidently, tapping the cigarettes. "Do you
smell the odor in this room? What is it like?"

"Stale tobacco," I replied.

"Exactly--nicotine. Two or three drops on the mouth-end of a cigar or
cigarette. The intended victim thinks it is only natural. But it is the
purest form of the deadly alkaloid--fatal in a few minutes, too."

He examined the thin little cigarettes more carefully. "Nicotine," he
went on, "was about the first alkaloid that was recovered from the body
by chemical analysis in a homicide case. That is the penetrating,
persistent odor you smelled at Fortescue's and also here. It's a very
good poison--if you are not particular about being discovered. A pound
of ordinary smoking tobacco contains from a half to an ounce of it. It
is almost entirely consumed by combustion; otherwise a pipeful would be
fatal. Of course they may have thought that investigators would believe
that their victims were inveterate smokers. But even the worst tobacco
fiend wouldn't show traces of the weed to such an extent."

Miss Lowe answered at last and Kennedy took the telephone.

"What is at five hundred and one East Fifth?" he asked.

"A headquarters of the Group in the city," she answered. "Why?"

"Well, I believe that the plans of that gun are there and that the
Baron--"

"You damned spies!" came a voice from behind us.

Kennedy dropped the receiver, turning quickly, his automatic gleaming
in his hand.

There was just a glimpse of a man with glittering bright blue eyes that
had an almost fiendish, baleful glare. An instant later the door which
had so unexpectedly opened banged shut, we heard a key turn in the
lock--and the man dropped to the floor before even Kennedy's automatic
could test its ability to penetrate wood on a chance at hitting
something the other side of it.

We were prisoners!

My mind worked automatically. At this very moment, perhaps, Baron
Kreiger might be negotiating for the electro-magnetic gun. We had found
out where he was, in all probability, but we were powerless to help
him. I thought of Miss Lowe, and picked up the receiver which Kennedy
had dropped.

She did not answer. The wire had been cut. We were isolated!

Kennedy had jumped to the window. I followed to restrain him, fearing
that he had some mad scheme for climbing out. Instead, quickly he
placed a peculiar arrangement, from the little package he had brought,
holding it to his eye as if sighting it, his right hand grasping a
handle as one holds a stereoscope. A moment later, as I examined it
more closely, I saw that instead of looking at anything he had before
him a small parabolic mirror turned away from him.

His finger pressed alternately on a button on the handle and I could
see that there flashed in the little mirror a minute incandescent lamp
which seemed to have a special filament arrangement.

The glaring sun was streaming in at the window and I wondered what
could possibly be accomplished by the little light in competition with
the sun itself.

"Signaling by electric light in the daytime may sound to you
ridiculous," explained Craig, still industriously flashing the light,
"but this arrangement with Professor Donath's signal mirror makes it
possible, all right.

"I hadn't expected this, but I thought I might want to communicate with
Burke quickly. You see, I sight the lamp and then press the button
which causes the light in the mirror to flash. It seems a paradox that
a light like this can be seen from a distance of even five miles and
yet be invisible to one for whom it was not intended, but it is so. I
use the ordinary Morse code--two seconds for a dot, six for a dash with
a four-second interval."

"What message did you send?" I asked.

"I told him that Baron Kreiger was at five hundred and one East Fifth,
probably; to get the secret service office in New York by wire and have
them raid the place, then to come and rescue us. That was Annenberg. He
must have come up by that trolley we heard passing just before."

The minutes seemed ages as we waited for Burke to start the machinery
of the raid and then come for us.

"No--you can't have a cigarette--and if I had a pair of bracelets with
me, I'd search you myself," we heard a welcome voice growl outside the
door a few minutes later. "Look in that other pocket, Tom."

The lock grated back and there stood Burke holding in a grip of steel
the undersized Annenberg, while the chauffeur who had driven our car
swung open the door.

"I'd have been up sooner," apologized Burke, giving the anarchist an
extra twist just to let him know that he was at last in the hands of
the law, "only I figured that this fellow couldn't have got far away in
this God-forsaken Ducktown and I might as well pick him up while I had
a chance. That's a great little instrument of yours, Kennedy. I got
you, fine."

Annenberg, seeing we were now four to one, concluded that discretion
was the better part of valor and ceased to struggle, though now and
then I could see he glanced at Kennedy out of the corner of his eye. To
every question he maintained a stolid silence.

A few minutes later, with the arch anarchist safely pinioned between
us, we were speeding back toward New York, laying plans for Burke to
dispatch warnings abroad to those whose names appeared on the fatal
list, and at the same time to round up as many of the conspirators as
possible in America.

As for Kennedy, his main interest now lay in Baron Kreiger and Paula.
While she had been driven frantic by the outcome of the terrible pact
into which she had been drawn, some one, undoubtedly, had been trying
to sell Baron Kreiger the gun that had been stolen from the American
inventor. Once they had his money and he had received the plans of the
gun, a fatal cigarette would be smoked. Could we prevent it?

On we tore back to the city, across the bridge and down through the
canyons of East Side streets.

At last we pulled up before the tenement at five hundred and one. As we
did so, one of Burke's men jumped out of the doorway.

"Are we in time?" shouted Burke.

"It's an awful mix-up," returned the man. "I can't make anything out of
it, so I ordered 'em all held here till you came."

We pushed past without a word of criticism of his wonderful acumen.

On the top floor we came upon a young man, bending over the form of a
girl who had fainted. On the floor of the middle of the room was a mass
of charred papers which had evidently burned a hole in the carpet
before they had been stamped out. Near by was an unlighted cigarette,
crushed flat on the floor.

"How is she?" asked Kennedy anxiously of the young man, as he dropped
down on the other side of the girl.

It was Paula. She had fainted, but was just now coming out of the
borderland of unconsciousness.

"Was I in time? Had he smoked it?" she moaned weakly, as there swam
before her eyes, evidently, a hazy vision of our faces.

Kennedy turned to the young man.

"Baron Kreiger, I presume?" he inquired.

The young man nodded.

"Burke of the Secret Service," introduced Craig, indicating our friend.
"My name is Kennedy. Tell what happened."

"I had just concluded a transaction," returned Kreiger in good but
carefully guarded English. "Suddenly the door burst open. She seized
these papers and dashed a cigarette out of my hands. The next instant
she had touched a match to them and had fallen in a faint almost in the
blaze. Strangest experience I ever had in my life. Then all these other
fellows came bursting in--said they were Secret Service men, too."

Kennedy had no time to reply, for a cry from Annenberg directed our
attention to the next room where on a couch lay a figure all huddled up.

As we looked we saw it was a woman, her head sweating profusely, and
her hands cold and clammy. There was a strange twitching of the muscles
of the face, the pupils of her eyes were widely dilated, her pulse weak
and irregular. Evidently her circulation had failed so that it
responded only feebly to stimulants, for her respiration was slow and
labored, with loud inspiratory gasps.

Annenberg had burst with superhuman strength from Burke's grasp and was
kneeling by the side of his wife's deathbed.

"It--was all Paula's fault--" gasped the woman. "I--knew I had
better--carry it through--like the Fortescue visit--alone."

I felt a sense of reassurance at the words. At least my suspicions had
been unfounded. Paula was innocent of the murder of Fortescue.

"Severe, acute nicotine poisoning," remarked Kennedy, as he rejoined us
a moment later. "There is nothing we can do--now."

Paula moved at the words, as though they had awakened a new energy in
her. With a supreme effort she raised herself.

"Then I--I failed?" she cried, catching sight of Kennedy.

"No, Miss Lowe," he answered gently. "You won. The plans of the
terrible gun are destroyed. The Baron is safe. Mrs. Annenberg has
herself smoked one of the fatal cigarettes intended for him."

Kreiger looked at us, uncomprehending. Kennedy picked up the crushed,
unlighted cigarette and laid it in the palm of his hand beside another,
half smoked, which he had found beside Mrs. Annenberg.

"They are deadly," he said simply to Kreiger. "A few drops of pure
nicotine hidden by that pretty gilt tip would have accomplished all
that the bitterest anarchist could desire."

All at once Kreiger seemed to realize what he had escaped so narrowly.
He turned toward Paula. The revulsion of her feelings at seeing him
safe was too much for her shattered nerves.

With a faint little cry, she tottered.

Before any of us could reach her, he had caught her in his arms and
imprinted a warm kiss on the insensible lips.

"Some water--quick!" he cried, still holding her close.



CHAPTER IV

THE AIR PIRATE


Rounding up the "Group" took several days, and it proved to be a great
story for the Star. I was pretty fagged when it was all over, but there
was a great deal of satisfaction in knowing that we had frustrated one
of the most daring anarchist plots of recent years.

"Can you arrange to spend the week-end with me at Stuyvesant
Verplanck's at Bluffwood?" asked Kennedy over the telephone, the
afternoon that I had completed my work on the newspaper of undoing what
Annenberg and the rest had attempted.

"How long since society took you up?" I asked airily, adding, "Is it a
large house party you are getting up?"

"You have heard of the so-called 'phantom bandit' of Bluffwood, haven't
you?" he returned rather brusquely, as though there was no time now for
bantering.

I confess that in the excitement of the anarchists I had forgotten it,
but now I recalled that for several days I had been reading little
paragraphs about robberies on the big estates on the Long Island shore
of the Sound. One of the local correspondents had called the robber a
"phantom bandit," but I had thought it nothing more than an attempt to
make good copy out of a rather ordinary occurrence.

"Well," he hurried on, "that's the reason why I have been 'taken up by
society,' as you so elegantly phrase it. From the secret hiding-places
of the boudoirs and safes of fashionable women at Bluffwood, thousands
of dollars' worth of jewels and other trinkets have mysteriously
vanished. Of course you'll come along. Why, it will be just the story
to tone up that alleged page of society news you hand out in the Sunday
Star. There--we're quits now. Seriously, though, Walter, it really
seems to be a very baffling case, or rather series of cases. The whole
colony out there is terrorized. They don't know who the robber is, or
how he operates, or who will be the next victim, but his skill and
success seem almost uncanny. Mr. Verplanck has put one of his cars at
my disposal and I'm up here at the laboratory gathering some apparatus
that may be useful. I'll pick you up anywhere between this and the
Bridge--how about Columbus Circle in half an hour?"

"Good," I agreed, deciding quickly from his tone and manner of
assurance that it would be a case I could not afford to miss.

The Stuyvesant Verplancks, I knew, were among the leaders of the rather
recherche society at Bluffwood, and the pace at which Bluffwood moved
and had its being was such as to guarantee a good story in one way or
another.

"Why," remarked Kennedy, as we sped out over the picturesque roads of
the north shore of Long Island, "this fellow, or fellows, seems to have
taken the measure of all the wealthy members of the exclusive
organizations out there--the Westport Yacht Club, the Bluffwood Country
Club, the North Shore Hunt, and all of them. It's a positive scandal,
the ease with which he seems to come and go without detection, striking
now here, now there, often at places that it seems physically
impossible to get at, and yet always with the same diabolical skill and
success. One night he will take some baubles worth thousands, the next
pass them by for something apparently of no value at all, a piece of
bric-a-brac, a bundle of letters, anything."

"Seems purposeless, insane, doesn't it?" I put in.

"Not when he always takes something--often more valuable than money,"
returned Craig.

He leaned back in the car and surveyed the glimpses of bay and
countryside as we were whisked by the breaks in the trees.

"Walter," he remarked meditatively, "have you ever considered the
possibilities of blackmail if the right sort of evidence were obtained
under this new 'white-slavery act'? Scandals that some of the fast set
may be inclined to wink at, that at worst used to end in Reno, become
felonies with federal prison sentences looming up in the background.
Think it over."

Stuyvesant Verplanck had telephoned rather hurriedly to Craig earlier
in the day, retaining his services, but telling only in the briefest
way of the extent of the depredations, and hinting that more than
jewelry might be at stake.

It was a pleasant ride, but we finished it in silence. Verplanck was,
as I recalled, a large masterful man, one of those who demanded and
liked large things--such as the estate of several hundred acres which
we at last entered.

It was on a neck of land with the restless waters of the Sound on one
side and the calmer waters of the bay on the other. Westport Bay lay in
a beautifully wooded, hilly country, and the house itself was on an
elevation, with a huge sweep of terraced lawn before it down to the
water's edge. All around, for miles, were other large estates, a
veritable colony of wealth.

As we pulled up under the broad stone porte-cochere, Verplanck, who had
been expecting us, led the way into his library, a great room,
literally crowded with curios and objects of art which he had collected
on his travels. It was a superb mental workshop, overlooking the bay,
with a stretch of several miles of sheltered water.

"You will recall," began Verplanck, wasting no time over preliminaries,
but plunging directly into the subject, "that the prominent robberies
of late have been at seacoast resorts, especially on the shores of Long
Island Sound, within, say, a hundred miles of New York. There has been
a great deal of talk about dark and muffled automobiles that have
conveyed mysterious parties swiftly and silently across country.

"My theory," he went on self-assertively, "is that the attack has been
made always along water routes. Under shadow of darkness, it is easy to
slip into one of the sheltered coves or miniature fiords with which the
north coast of the Island abounds, land a cut-throat crew primed with
exact information of the treasure on some of these estates. Once the
booty is secured, the criminal could put out again into the Sound
without leaving a clue."

He seemed to be considering his theory. "Perhaps the robberies last
summer at Narragansett, Newport, and a dozen other New England places
were perpetrated by the same cracksman. I believe," he concluded,
lowering his voice, "that there plies to-day on the wide waters of the
Sound a slim, swift motor boat which wears the air of a pleasure craft,
yet is as black a pirate as ever flew the Jolly Roger. She may at this
moment be anchored off some exclusive yacht club, flying the
respectable burgee of the club--who knows?"

He paused as if his deductions settled the case so far. He would have
resumed in the same vein, if the door had not opened. A lady in a
cobwebby gown entered the room. She was of middle age, but had retained
her youth with a skill that her sisters of less leisure always envy.
Evidently she had not expected to find anyone, yet nothing seemed to
disconcert her.

"Mrs. Verplanck," her husband introduced, "Professor Kennedy and his
associate, Mr. Jameson--those detectives we have heard about. We were
discussing the robberies."

"Oh, yes," she said, smiling, "my husband has been thinking of forming
himself into a vigilance committee. The local authorities are all at
sea."

I thought there was a trace of something veiled in the remark and
fancied, not only then but later, that there was an air of constraint
between the couple.

"You have not been robbed yourself?" queried Craig tentatively.

"Indeed we have," exclaimed Verplanck quickly. "The other night I was
awakened by the noise of some one down here in this very library. I
fired a shot, wild, and shouted, but before I could get down here the
intruder had fled through a window, and half rolling down the terraces.
Mrs. Verplanck was awakened by the rumpus and both of us heard a
peculiar whirring noise."

"Like an automobile muffled down," she put in.

"No," he asserted vigorously, "more like a powerful motor boat, one
with the exhaust under water."

"Well," she shrugged, "at any rate, we saw no one."

"Did the intruder get anything?"

"That's the lucky part. He had just opened this safe apparently and
begun to ransack it. This is my private safe. Mrs. Verplanck has
another built into her own room upstairs where she keeps her jewels."

"It is not a very modern safe, is it?" ventured Kennedy. "The fellow
ripped off the outer casing with what they call a 'can-opener.'"

"No. I keep it against fire rather than burglars. But he overlooked a
box of valuable heirlooms, some silver with the Verplanck arms. I think
I must have scared him off just in time. He seized a package in the
safe, but it was only some business correspondence. I don't relish
having lost it, particularly. It related to a gentlemen's agreement a
number of us had in the recent cotton corner. I suppose the Government
would like to have it. But--here's the point. If it is so easy to get
in and get away, no one in Bluffwood is safe."

"Why, he robbed the Montgomery Carter place the other night," remarked
Mrs. Verplanck, "and almost got a lot of old Mrs. Carter's jewels as
well as stuff belonging to her son, Montgomery, Junior. That was the
first robbery. Mr. Carter, that is Junior--Monty, everyone calls
him--and his chauffeur almost captured the fellow, but he managed to
escape in the woods."

"In the woods?" repeated Craig.

Mrs. Verplanck nodded. "But they saved the loot he was about to take."

"Oh, no one is safe any more," reiterated Verplanck. "Carter seems to
be the only one who has had a real chance at him, and he was able to
get away neatly."

"But he's not the only one who got off without a loss," she put in
significantly. "The last visit--" Then she paused.

"Where was the last attempt?" asked Kennedy.

"At the house of Mrs. Hollingsworth--around the point on this side of
the bay. You can't see it from here."

"I'd like to go there," remarked Kennedy.

"Very well. Car or boat?"

"Boat, I think."

"Suppose we go in my little runabout, the Streamline II? She's as fast
as any ordinary automobile."

"Very good. Then we can get an idea of the harbor."

"I'll telephone first that we are coming," said Verplanck.

"I think I'll go, too," considered Mrs. Verplanck, ringing for a heavy
wrap.

"Just as you please," said Verplanck.

The Streamline was a three-stepped boat which. Verplanck had built for
racing, a beautiful craft, managed much like a racing automobile. As
she started from the dock, the purring drone of her eight cylinders
sent her feathering over the waves like a skipping stone. She sank back
into the water, her bow leaping upward, a cloud of spray in her wake,
like a waterspout.

Mrs. Hollingsworth was a wealthy divorcee, living rather quietly with
her two children, of whom the courts had awarded her the care. She was
a striking woman, one of those for whom the new styles of dress seem
especially to have been designed. I gathered, however, that she was not
on very good terms with the little Westport clique in which the
Verplancks moved, or at least not with Mrs. Verplanck. The two women
seemed to regard each other rather coldly, I thought, although Mr.
Verplanck, man-like, seemed to scorn any distinctions and was more than
cordial. I wondered why Mrs. Verplanck had come.

The Hollingsworth house was a beautiful little place down the bay from
the Yacht Club, but not as far as Verplanck's, or the Carter estate,
which was opposite.

"Yes," replied Mrs. Hollingsworth when the reason for our visit had
been explained, "the attempt was a failure. I happened to be awake,
rather late, or perhaps you would call it early. I thought I heard a
noise as if some one was trying to break into the drawing-room through
the window. I switched on all the lights. I have them arranged so for
just that purpose of scaring off intruders. Then, as I looked out of my
window on the second floor, I fancied I could see a dark figure slink
into the shadow of the shrubbery at the side of the house. Then there
was a whirr. It might have been an automobile, although it sounded
differently from that--more like a motor boat. At any rate, there was
no trace of a car that we could discover in the morning. The road had
been oiled, too, and a car would have left marks. And yet some one was
here. There were marks on the drawing-room window just where I heard
the sounds."

Who could it be? I asked myself as we left. I knew that the great army
of chauffeurs was infested with thieves, thugs and gunmen. Then, too,
there were maids, always useful as scouts for these corsairs who prey
on the rich. Yet so adroitly had everything been done in these cases
that not a clue seemed to have been left behind by which to trace the
thief.

We returned to Verplanck's in the Streamline in record time, dined, and
then found McNeill, a local detective, waiting to add his quota of
information. McNeill was of the square-toed, double-chinned,
bull-necked variety, just the man to take along if there was any
fighting. He had, however, very little to add to the solution of the
mystery, apparently believing in the chauffeur-and-maid theory.

It was too late to do anything more that night, and we sat on the
Verplanck porch, overlooking the beautiful harbor. It was a black, inky
night, with no moon, one of those nights when the myriad lights on the
boats were mere points in the darkness. As we looked out over the
water, considering the case which as yet we had hardly started on,
Kennedy seemed engrossed in the study in black.

"I thought I saw a moving light for an instant across the bay, above
the boats, and as though it were in the darkness of the hills on the
other side. Is there a road over there, above the Carter house?" he
asked suddenly.

"There is a road part of the way on the crest of the hill," replied
Mrs. Verplanck. "You can see a car on it, now and then, through the
trees, like a moving light."

"Over there, I mean," reiterated Kennedy, indicating the light as it
flashed now faintly, then disappeared, to reappear further along, like
a gigantic firefly in the night.

"N-no," said Verplanck. "I don't think the road runs down as far as
that. It is further up the bay."

"What is it then?" asked Kennedy, half to himself. "It seems to be
traveling rapidly. Now it must be about opposite the Carter house.
There--it has gone."

We continued to watch for several minutes, but it did not reappear.
Could it have been a light on the mast of a boat moving rapidly up the
bay and perhaps nearer to us than we suspected? Nothing further
happened, however, and we retired early, expecting to start with fresh
minds on the case in the morning. Several watchmen whom Verplanck
employed both on the shore and along the driveways were left guarding
every possible entrance to the estate.

Yet the next morning as we met in the cheery east breakfast room,
Verplanck's gardener came in, hat in hand, with much suppressed
excitement.

In his hand he held an orange which he had found in the shrubbery
underneath the windows of the house. In it was stuck a long nail and to
the nail was fastened a tag.

Kennedy read it quickly.

"If this had been a bomb, you and your detectives would never have
known what struck you.

"AQUAERO."



CHAPTER V

THE ULTRA-VIOLET RAY


"Good Gad, man!" exclaimed Verplanck, who had read it over Craig's
shoulder. "What do you make of THAT?"

Kennedy merely shook his head. Mrs. Verplanck was the calmest of all.

"The light," I cried. "You remember the light? Could it have been a
signal to some one on this side of the bay, a signal light in the
woods?"

"Possibly," commented Kennedy absently, adding, "Robbery with this
fellow seems to be an art as carefully strategized as a promoter's plan
or a merchant's trade campaign. I think I'll run over this morning and
see if there is any trace of anything on the Carter estate."

Just then the telephone rang insistently. It was McNeill, much excited,
though he had not heard of the orange incident. Verplanck answered the
call.

"Have you heard the news?" asked McNeill. "They report this morning
that that fellow must have turned up last night at Belle Aire."

"Belle Aire? Why, man, that's fifty miles away and on the other side of
the island. He was here last night," and Verplanck related briefly the
find of the morning. "No boat could get around the island in that time
and as for a car--those roads are almost impossible at night."

"Can't help it," returned McNeill doggedly. "The Halstead estate out at
Belle Aire was robbed last night. It's spooky all right."

"Tell McNeill I want to see him--will meet him in the village
directly," cut in Craig before Verplanck had finished.

We bolted a hasty breakfast and in one of Verplanck's cars hurried to
meet McNeill.

"What do you intend doing?" he asked helplessly, as Kennedy finished
his recital of the queer doings of the night before.

"I'm going out now to look around the Carter place. Can you come along?"

"Surely," agreed McNeill, climbing into the car. "You know him?"

"No."

"Then I'll introduce you. Queer chap, Carter. He's a lawyer, although I
don't think he has much practice, except managing his mother's estate."

McNeill settled back in the luxurious car with an exclamation of
satisfaction.

"What do you think of Verplanck?" he asked.

"He seems to me to be a very public-spirited man," answered Kennedy
discreetly.

That, however, was not what McNeill meant and he ignored it. And so for
the next ten minutes we were entertained with a little retail scandal
of Westport and Bluffwood, including a tale that seemed to have gained
currency that Verplanck and Mrs. Hollingsworth were too friendly to
please Mrs. Verplanck. I set the whole thing down to the hostility and
jealousy of the towns people who misinterpret everything possible in
the smart set, although I could not help recalling how quickly she had
spoken when we had visited the Hollingsworth house in the Streamline
the day before.

Montgomery Carter happened to be at home and, at least openly,
interposed no objection to our going about the grounds.

"You see," explained Kennedy, watching the effect of his words as if to
note whether Carter himself had noticed anything unusual the night
before, "we saw a light moving over here last night. To tell the truth,
I half expected you would have a story to add to ours, of a second
visit."

Carter smiled. "No objection at all. I'm simply nonplussed at the nerve
of this fellow, coming back again. I guess you've heard what a narrow
squeak he had with me. You're welcome to go anywhere, just so long as
you don't disturb my study down there in the boathouse. I use that
because it overlooks the bay--just the place to study over knotty legal
problems."

Back of, or in front of the Carter house, according as you fancied it
faced the bay or not, was the boathouse, built by Carter's father, who
had been a great yachtsman in his day and commodore of the club. His
son had not gone in much for water sports and had converted the corner
underneath a sort of observation tower into a sort of country law
office.

"There has always seemed to me to be something strange about that
boathouse since the old man died," remarked McNeill in a half whisper
as we left Carter. "He always keeps it locked and never lets anyone go
in there, although they say he has it fitted beautifully with hundreds
of volumes of law books, too."

Kennedy had been climbing the hill back of the house and now paused to
look about. Below was the Carter garage.

"By the way," exclaimed McNeill, as if he had at last hit on a great
discovery, "Carter has a new chauffeur, a fellow named Wickham. I just
saw him driving down to the village. He's a chap that it might pay us
to watch--a newcomer, smart as a steel trap, they say, but not much of
a talker."

"Suppose you take that job--watch him," encouraged Kennedy. "We can't
know too much about strangers here, McNeill."

"That's right," agreed the detective. "I'll follow him back to the
village and get a line on him."

"Don't be easily discouraged," added Kennedy, as McNeill started down
the hill to the garage. "If he is a fox he'll try to throw you off the
trail. Hang on."

"What was that for?" I asked as the detective disappeared. "Did you
want to get rid of him?"

"Partly," replied Craig, descending slowly, after a long survey of the
surrounding country.

We had reached the garage, deserted now except for our own car.

"I'd like to investigate that tower," remarked Kennedy with a keen look
at me, "if it could be done without seeming to violate Mr. Carter's
hospitality."

"Well," I observed, my eye catching a ladder beside the garage,
"there's a ladder. We can do no more than try."

He walked over to the automobile, took a little package out, slipped it
into his pocket, and a few minutes later we had set the ladder up
against the side of the boathouse farthest away from the house. It was
the work of only a moment for Kennedy to scale it and prowl across the
roof to the tower, while I stood guard at the foot.

"No one has been up there recently," he panted breathlessly as he
rejoined me. "There isn't a sign."

We took the ladder quietly back to the garage, then Kennedy led the way
down the shore to a sort of little summerhouse cut off from the
boathouse and garage by the trees, though over the top of a hedge one
could still see the boathouse tower.

We sat down, and Craig filled his lungs with the good salt air,
sweeping his eye about the blue and green panorama as though this were
a holiday and not a mystery case.

"Walter," he said at length, "I wish you'd take the car and go around
to Verplanck's. I don't think you can see the tower through the trees,
but I should like to be sure."

I found that it could not be seen, though I tried all over the place
and got myself disliked by the gardener and suspected by a watchman
with a dog.

It could not have been from the tower of the boathouse that we had seen
the light, and I hurried back to Craig to tell him so. But when I
returned, I found that he was impatiently pacing the little rustic
summerhouse, no longer interested in what he had sent me to find out.

"What has happened?" I asked eagerly.

"Just come out here and I'll show you something," he replied, leaving
the summerhouse and approaching the boathouse from the other side of
the hedge, on the beach, so that the house itself cut us off from
observation from Carter's.

"I fixed a lens on the top of that tower when I was up there," he
explained, pointing up at it. "It must be about fifty feet high. From
there, you see, it throws a reflection down to this mirror. I did it
because through a skylight in the tower I could read whatever was
written by anyone sitting at Carter's desk in the corner under it."

"Read?" I repeated, mystified.

"Yes, by invisible light," he continued. "This invisible light
business, you know, is pretty well understood by this time. I was only
repeating what was suggested once by Professor Wood of Johns Hopkins.
Practically all sources of light, you understand, give out more or less
ultraviolet light, which plays no part in vision whatever. The human
eye is sensitive to but few of the light rays that reach it, and if our
eyes were constituted just the least bit differently we should have an
entirely different set of images.

"But by the use of various devices we can, as it were, translate these
ultraviolet rays into terms of what the human eye can see. In order to
do it, all the visible light rays which show us the thing as we see
it--the tree green, the sky blue--must be cut off. So in taking an
ultraviolet photograph a screen must be used which will be opaque to
these visible rays and yet will let the ultraviolet rays through to
form the image. That gave Professor Wood a lot of trouble. Glass won't
do, for glass cuts off the ultraviolet rays entirely. Quartz is a very
good medium, but it does not cut off all the visible light. In fact
there is only one thing that will do the work, and that is metallic
silver."

I could not fathom what he was driving at, but the fascination of
Kennedy himself was quite sufficient.

"Silver," he went on, "is all right if the objects can be illuminated
by an electric spark or some other source rich in the rays. But it
isn't entirely satisfactory when sunlight is concerned, for various
reasons that I need not bore you with. Professor Wood has worked out a
process of depositing nickel on glass. That's it up there," he
concluded, wheeling a lower reflector about until it caught the image
of the afternoon sun thrown from the lens on the top of the tower.

"You see," he resumed, "that upper lens is concave so that it enlarges
tremendously. I can do some wonderful tricks with that."

I had been lighting a cigarette and held a box of safety wind matches
in my hand.

"Give me that matchbox," he asked.

He placed it at the foot of the tower. Then he went off, I should say,
without exaggeration, a hundred feet.

The lettering on the matchbox could be seen in the silvered mirror,
enlarged to such a point that the letters were plainly visible!

"Think of the possibilities in that," he added excitedly. "I saw them
at once. You can read what some one is writing at a desk a hundred,
perhaps two hundred feet away."

"Yes," I cried, more interested in the practical aspects of it than in
the mechanics and optics. "What have you found?"

"Some one came into the boathouse while you were away," he said. "He
had a note. It read, 'Those new detectives are watching everything. We
must have the evidence. You must get those letters to-night, without
fail.'"

"Letters--evidence," I repeated. "Who wrote it? Who received it?"

"I couldn't see over the hedge who had entered the boathouse, and by
the time I got around here he was gone."

"Was it Wickham--or intended for Wickham?" I asked.

Kennedy shrugged his shoulders.

"We'll gain nothing by staying here," he said. "There is just one
possibility in the case, and I can guard against that only by returning
to Verplanck's and getting some of that stuff I brought up here with
me. Let us go."

Late in the afternoon though it was, after our return, Kennedy insisted
on hurrying from Verplanck's to the Yacht Club up the bay. It was a
large building, extending out into the water on made land, from which
ran a long, substantial dock. He had stopped long enough only to ask
Verplanck to lend him the services of his best mechanician, a Frenchman
named Armand.

On the end of the yacht club dock Kennedy and Armand set up a large
affair which looked like a mortar. I watched curiously, dividing my
attention between them and the splendid view of the harbor which the
end of the dock commanded on all sides.

"What is this?" I asked finally. "Fireworks?"

"A rocket mortar of light weight," explained Kennedy, then dropped into
French as he explained to Armand the manipulation of the thing.

There was a searchlight near by on the dock.

"You can use that?" queried Kennedy.

"Oh, yes. Mr. Verplanck, he is vice-commodore of the club. Oh, yes, I
can use that. Why, Monsieur?"

Kennedy had uncovered a round brass case. It did not seem to amount to
much, as compared to some of the complicated apparatus he had used. In
it was a four-sided prism of glass--I should have said, cut off the
corner of a huge glass cube.

He handed it to us.

"Look in it," he said.

It certainly was about the most curious piece of crystal gazing I had
ever done. Turn the thing any way I pleased and I could see my face in
it, just as in an ordinary mirror.

"What do you call it?" Armand asked, much interested.

"A triple mirror," replied Kennedy, and again, half in English and half
in French, neither of which I could follow, he explained the use of the
mirror to the mechanician.

We were returning up the dock, leaving Armand with instructions to be
at the club at dusk, when we met McNeill, tired and disgusted.

"What luck?" asked Kennedy.

"Nothing," he returned. "I had a 'short' shadow and a 'long' shadow at
Wickham's heels all day. You know what I mean. Instead of one man,
two--the second sleuthing in the other's tracks. If he escaped Number
One, Number Two would take it up, and I was ready to move up into
Number Two's place. They kept him in sight about all the time. Not a
fact. But then, of course, we don't know what he was doing before we
took up tailing him. Say," he added, "I have just got word from an
agency with which I correspond in New York that it is reported that a
yeggman named 'Australia Mac,' a very daring and clever chap, has been
attempting to dispose of some of the goods which we know have been
stolen through one of the worst 'fences' in New York."

"Is that all?" asked Craig, with the mention of Australia Mac showing
the first real interest yet in anything that McNeill had done since we
met him the night before.

"All so far. I wired for more details immediately."

"Do you know anything about this Australia Mac?"

"Not much. No one does. He's a new man, it seems, to the police here."

"Be here at eight o'clock, McNeill," said Craig, as we left the club
for Verplanck's. "If you can find out more about this yeggman, so much
the better."

"Have you made any progress?" asked Verplanck as we entered the estate
a few minutes later.

"Yes," returned Craig, telling only enough to whet his interest.
"There's a clue, as I half expected, from New York, too. But we are so
far away that we'll have to stick to my original plan. You can trust
Armand?"

"Absolutely."

"Then we shall transfer our activity to the Yacht Club to-night," was
all that Kennedy vouchsafed.



CHAPTER VI

THE TRIPLE MIRROR


It was the regular Saturday night dance at the club, a brilliant
spectacle, faces that radiated pleasure, gowns that for startling
combinations of color would have shamed a Futurist, music that set the
feet tapping irresistibly--a scene which I shall pass over because it
really has no part in the story.

The fascination of the ballroom was utterly lost on Craig. "Think of
all the houses only half guarded about here to-night," he mused, as we
joined Armand and McNeill on the end of the dock. I could not help
noting that that was the only idea which the gay, variegated, sparkling
tango throng conveyed to him.

In front of the club was strung out a long line of cars, and at the
dock several speed boats of national and international reputation,
among them the famous Streamline II, at our instant beck and call. In
it Craig had already placed some rather bulky pieces of apparatus, as
well as a brass case containing a second triple mirror like that which
he had left with Armand.

With McNeill, I walked back along the pier, leaving Kennedy with
Armand, until we came to the wide porch, where we joined the
wallflowers and the rocking-chair fleet. Mrs. Verplanck, I observed,
was a beautiful dancer. I picked her out in the throng immediately,
dancing with Carter.

McNeill tugged at my sleeve. Without a word I saw what he meant me to
see. Verplanck and Mrs. Hollingsworth were dancing together. Just then,
across the porch I caught sight of Kennedy at one of the wide windows.
He was trying to attract Verplanck's attention, and as he did so I
worked my way through the throng of chatting couples leaving the floor
until I reached him. Verplanck, oblivious, finished the dance; then,
seeming to recollect that he had something to attend to, caught sight
of us, and ran off during the intermission from the gay crowd to which
he resigned Mrs. Hollingsworth.

"What is it?" he asked.

"There's that light down the bay," whispered Kennedy.

Instantly Verplanck forgot about the dance.

"Where?" he asked.

"In the same place."

I had not noticed, but Mrs. Verplanck, woman-like, had been able to
watch several things at once. She had seen us and had joined us.

"Would you like to run down there in the Streamline?" he asked. "It
will only take a few minutes."

"Very much."

"What is it--that light again?" she asked, as she joined us in walking
down the dock.

"Yes," answered her husband, pausing to look for a moment at the stuff
Kennedy had left with Armand. Mrs. Verplanck leaned over the
Streamline, turned as she saw me, and said: "I wish I could go with
you. But evening dress is not the thing for a shivery night in a speed
boat. I think I know as much about it as Mr. Verplanck. Are you going
to leave Armand?"

"Yes," replied Kennedy, taking his place beside Verplanck, who was
seated at the steering wheel. "Walter and McNeill, if you two will sit
back there, we're ready. All right."

Armand had cast us off and Mrs. Verplanck waved from the end of the
float as the Streamline quickly shot out into the night, a buzzing,
throbbing shape of mahogany and brass, with her exhausts sticking out
like funnels and booming like a pipe organ. It took her only seconds to
eat into the miles.

"A little more to port," said Kennedy, as Verplanck swung her around.

Just then the steady droning of the engine seemed a bit less
rhythmical. Verplanck throttled her down, but it had no effect. He shut
her off. Something was wrong. As he crawled out into the space forward
of us where the engine was, it seemed as if the Streamline had broken
down suddenly and completely.

Here we were floundering around in the middle of the bay.

"Chuck-chuck-chuck," came in quick staccato out of the night. It was
Montgomery Carter, alone, on his way across the bay from the club, in
his own boat.

"Hello--Carter," called Verplanck.

"Hello, Verplanck. What's the matter?"

"Don't know. Engine trouble of some kind. Can you give us a line?"

"I've got to go down to the house," he said, ranging up near us. "Then
I can take you back. Perhaps I'd better get you out of the way of any
other boats first. You don't mind going over and then back?"

Verplanck looked at Craig. "On the contrary," muttered Craig, as he
made fast the welcome line.

The Carter dock was some three miles from the club on the other side of
the bay. As we came up to it, Carter shut off his engine, bent over it
a moment, made fast, and left us with a hurried, "Wait here."

Suddenly, overhead, we heard a peculiar whirring noise that seemed to
vibrate through the air. Something huge, black, monster-like, slid down
a board runway into the water, traveled a few feet, in white suds and
spray, rose in the darkness--and was gone!

As the thing disappeared, I thought I could hear a mocking laugh flung
back at us.

"What is it?" I asked, straining my eyes at what had seemed for an
instant like a great flying fish with finny tail and huge fins at the
sides and above.

"'Aquaero,'" quoted Kennedy quickly. "Don't you understand--a
hydroaeroplane--a flying boat. There are hundreds of privately owned
flying boats now wherever there is navigable water. That was the secret
of Carter's boathouse, of the light we saw in the air."

"But this Aquaero--who is he?" persisted McNeill.
"Carter--Wickham--Australia Mac?"

We looked at each other blankly. No one said a word. We were captured,
just as effectively as if we were ironed in a dungeon. There were the
black water, the distant lights, which at any other time I should have
said would have been beautiful.

Kennedy had sprung into Carter's boat.

"The deuce," he exclaimed. "He's put her out of business."

Verplanck, chagrined, had been going over his own engine feverishly.
"Do you see that?" he asked suddenly, holding up in the light of a
lantern a little nut which he had picked out of the complicated
machinery. "It never belonged to this engine. Some one placed it there,
knowing it would work its way into a vital part with the vibration."

Who was the person, the only one who could have done it? The answer was
on my lips, but I repressed it. Mrs. Verplanck herself had been bending
over the engine when last I saw her. All at once it flashed over me
that she knew more about the phantom bandit than she had admitted. Yet
what possible object could she have had in putting the Streamline out
of commission?

My mind was working rapidly, piecing together the fragmentary facts.
The remark of Kennedy, long before, instantly assumed new significance.
What were the possibilities of blackmail in the right sort of evidence?
The yeggman had been after what was more valuable than jewels--letters!
Whose? Suddenly I saw the situation. Carter had not been robbed at all.
He was in league with the robber. That much was a blind to divert
suspicion. He was a lawyer--some one's lawyer. I recalled the message
about letters and evidence, and as I did so there came to mind a
picture of Carter and the woman he had been dancing with. In return for
his inside information about the jewels of the wealthy homes of
Bluffwood, the yeggman was to get something of interest and importance
to his client.

The situation called for instant action. Yet what could we do, marooned
on the other side of the bay?

From the Club dock a long finger of light swept out into the night,
plainly enough near the dock, but diffused and disclosing nothing in
the distance. Armand had trained it down the bay in the direction we
had taken, but by the time the beam reached us it was so weak that it
was lost.

Craig had leaped up on the Carter dock and was capping and uncapping
with the brass cover the package which contained the triple mirror.

Still in the distance I could see the wide path of light, aimed toward
us, but of no avail.

"What are you doing?" I asked.

"Using the triple mirror to signal to Armand. It is something better
than wireless. Wireless requires heavy and complicated apparatus. This
is portable, heatless, almost weightless, a source of light depending
for its power on another source of light at a great distance."

I wondered how Armand could ever detect its feeble ray.

"Even in the case of a rolling ship," Kennedy continued, alternately
covering and uncovering the mirror, "the beam of light which this
mirror reflects always goes back, unerring, to its source. It would do
so from an aeroplane, so high in the air that it could not be located.
The returning beam is invisible to anyone not immediately in the path
of the ray, and the ray always goes to the observer. It is simply a
matter of pure mathematics practically applied. The angle of incidence
equals the angle of reflection. There is not a variation of a foot in
two miles."

"What message are you sending him?" asked Verplanck.

"To tell Mrs. Hollingsworth to hurry home immediately," Kennedy
replied, still flashing the letters according to his code.

"Mrs. Hollingsworth?" repeated Verplanck, looking up.

"Yes. This hydroaeroplane yeggman is after something besides jewels
to-night. Were those letters that were stolen from you the only ones
you had in the safe?"

Verplanck looked up quickly. "Yes, yes. Of course."

"You had none from a woman--"

"No," he almost shouted. Of a sudden it seemed to dawn on him what
Kennedy was driving at--the robbery of his own house with no loss
except of a packet of letters on business, followed by the attempt on
Mrs. Hollingsworth. "Do you think I'd keep dynamite, even in the safe?"

To hide his confusion he had turned and was bending again over the
engine.

"How is it?" asked Kennedy, his signaling over.

"Able to run on four cylinders and one propeller," replied Verplanck.

"Then let's try her. Watch the engine. I'll take the wheel."

Limping along, the engine skipping and missing, the once peerless
Streamline started back across the bay. Instead of heading toward the
club, Kennedy pointed her bow somewhere between that and Verplanck's.

"I wish Armand would get busy," he remarked, after glancing now and
then in the direction of the club. "What can be the matter?"

"What do you mean?" I asked.

There came the boom as if of a gun far away in the direction in which
he was looking, then another.

"Oh, there it is. Good fellow. I suppose he had to deliver my message
to Mrs. Hollingsworth himself first."

From every quarter showed huge balls of fire, rising from the sea, as
it were, with a brilliantly luminous flame.

"What is it?" I asked, somewhat startled.

"A German invention for use at night against torpedo and aeroplane
attacks. From that mortar Armand has shot half a dozen bombs of
phosphide of calcium which are hurled far into the darkness. They are
so constructed that they float after a short plunge and are ignited on
contact by the action of the salt water itself."

It was a beautiful pyrotechnic display, lighting up the shore and hills
of the bay as if by an unearthly flare.

"There's that thing now!" exclaimed Kennedy.

In the glow we could see a peculiar, birdlike figure flying through the
air over toward the Hollingsworth house. It was the hydroaeroplane.

Out from the little stretch of lawn under the accentuated shadow of the
trees, she streaked into the air, swaying from side to side as the
pilot operated the stabilizers on the ends of the planes to counteract
the puffs of wind off the land.

How could she ever be stopped?

The Streamline, halting and limping, though she was, had almost crossed
the bay before the light bombs had been fired by Armand. Every moment
brought the flying boat nearer.

She swerved. Evidently the pilot had seen us at last and realized who
we were. I was so engrossed watching the thing that I had not noticed
that Kennedy had given the wheel to Verplanck and was standing in the
bow, endeavoring to sight what looked like a huge gun.

In rapid succession half a dozen shots rang out. I fancied I could
almost hear the ripping and tearing of the tough rubber-coated silken
wings of the hydroaeroplane as the wind widened the perforation the gun
had made.

She had not been flying high, but now she swooped down almost like a
gull, seeking to rest on the water. We were headed toward her now, and
as the flying boat sank I saw one of the passengers rise in his seat,
swing his arm, and far out something splashed in the bay.

On the water, with wings helpless, the flying boat was no match for the
Streamline now. She struck at an acute angle, rebounded in the air for
a moment, and with a hiss skittered along over the waves, planing with
the help of her exhaust under the step of the boat.

There she was, a hull, narrow, scow-bowed, like a hydroplane, with a
long pointed stern and a cockpit for two men, near the bow. There were
two wide, winglike planes, on a light latticework of wood covered with
silk, trussed and wired like a kite frame, the upper plane about five
feet above the lower, which was level with the boat deck. We could see
the eight-cylindered engine which drove a two-bladed wooden propeller,
and over the stern were the air rudder and the horizontal planes. There
she was, the hobbled steed now of the phantom bandit who had
accomplished the seemingly impossible.

In spite of everything, however, the flying boat reached the shore a
trifle ahead of us. As she did so both figures in her jumped, and one
disappeared quickly up the bank, leaving the other alone.

"Verplanck, McNeill--get him," cried Kennedy, as our own boat grated on
the beach. "Come, Walter, we'll take the other one."

The man had seen that there was no safety in flight. Down the shore he
stood, without a hat, his hair blown pompadour by the wind.

As we approached Carter turned superciliously, unbuttoning his bulky
khaki life preserver jacket.

"Well?" he asked coolly.

Not for a moment did Kennedy allow the assumed coolness to take him
back, knowing that Carter's delay did not cover the retreat of the
other man.

"So," Craig exclaimed, "you are the--the air pirate?"

Carter disdained to reply.

"It was you who suggested the millionaire households, full of jewels,
silver and gold, only half guarded; you, who knew the habits of the
people; you, who traded that information in return for another piece of
thievery by your partner, Australia Mac--Wickham he called himself here
in Bluffwood. It was you---"

A car drove up hastily, and I noted that we were still on the
Hollingsworth estate. Mrs. Hollingsworth had seen us and had driven
over toward us.

"Montgomery!" she cried, startled.

"Yes," said Kennedy quickly, "air pirate and lawyer for Mrs. Verplanck
in the suit which she contemplated bringing--"

Mrs. Hollingsworth grew pale under the ghastly, flickering light from
the bay.

"Oh!" she cried, realizing at what Kennedy hinted, "the letters!"

"At the bottom of the harbor, now," said Kennedy. "Mr. Verplanck tells
me he has destroyed his. The past is blotted out as far as that is
concerned. The future is--for you three to determine. For the present
I've caught a yeggman and a blackmailer."



CHAPTER VII

THE WIRELESS WIRETAPPERS


Kennedy did not wait at Bluffwood longer than was necessary. It was
easy enough now to silence Montgomery Carter, and the reconciliation of
the Verplancks was assured. In the Star I made the case appear at the
time to involve merely the capture of Australia Mac.

When I dropped into the office the next day as usual, I found that I
had another assignment that would take me out on Long Island. The story
looked promising and I was rather pleased to get it.

"Bound for Seaville, I'll wager," sounded a familiar voice in my ear,
as I hurried up to the train entrance at the Long Island corner of the
Pennsylvania Station.

I turned quickly, to find Kennedy just behind me, breathless and
perspiring.

"Er--yes," I stammered in surprise at seeing him so unexpectedly, "but
where did you come from? How did you know?"

"Let me introduce Mr. Jack Waldon," he went on, as we edged our way
toward the gate, "the brother of Mrs. Tracy Edwards, who disappeared so
strangely from the houseboat Lucie last night at Seaville. That is the
case you're going to write up, isn't it?"

It was then for the first time that I noticed the excited young man
beside Kennedy was really his companion.

I shook hands with Waldon, who gave me a grip that was both a greeting
and an added impulse in our general direction through the wicket.

"Might have known the Star would assign you to this Edwards case,"
panted Kennedy, mopping his forehead, for the heat in the terminal was
oppressive and the crowd, though not large, was closely packed. "Mr.
Jameson is my right-hand man," he explained to Waldon, taking us each
by the arm and urging us forward. "Waldon was afraid we might miss the
train or I should have tried to get you, Walter, at the office."

It was all done so suddenly that they quite took away what remaining
breath I had, as we settled ourselves to swelter in the smoker instead
of in the concourse. I did not even protest at the matter-of-fact
assurance with which Craig assumed that his deduction as to my
destination was correct.

Waldon, a handsome young fellow in a flannel suit and yachting cap
somewhat the worse for his evidently perturbed state of mind, seemed to
eye me for the moment doubtfully, in spite of Kennedy's cordial
greeting.

"I've had all the first editions of the evening papers," I hinted as we
sped through the tunnel, "but the stories seemed to be quite the
same--pretty meager in details."

"Yes," returned Waldon with a glance at Kennedy, "I tried to keep as
much out of the papers as I could just now for Lucie's sake."

"You needn't fear Jameson," remarked Kennedy.

He fumbled in his pocket, then paused a moment and shot a glance of
inquiry at Waldon, who nodded a mute acquiescence to him.

"There seem to have been a number of very peculiar disappearances
lately," resumed Kennedy, "but this case of Mrs. Edwards is by far the
most extraordinary. Of course the Star hasn't had that--yet," he
concluded, handing me a sheet of notepaper.

"Mr. Waldon didn't give it out, hoping to avoid scandal."

I took the paper and read eagerly, in a woman's hand:

"MY DEAR MISS FOX: I have been down here at Seaville on our houseboat,
the Lucie, for several days for a purpose which now is accomplished.

"Already I had my suspicions of you, from a source which I need not
name. Therefore, when the Kronprinz got into wireless communication
with the station at Seaville I determined through our own wireless on
the Lucie to overhear whether there would be any exchange of messages
between my husband and yourself.

"I was able to overhear the whole thing and I want you to know that
your secret is no longer a secret from me, and that I have already told
Mr. Edwards that I know it. You ruin his life by your intimacy which
you seem to want to keep up, although you know you have no right to do
it, but you shall not ruin mine.

"I am thoroughly disillusioned now. I have not decided on what steps to
take, but--"

Only a casual glance was necessary to show me that the writing seemed
to grow more and more weak as it progressed, and the note stopped
abruptly, as if the writer had been suddenly interrupted or some new
idea had occurred to her.

Hastily I tried to figure it out. Lucie Waldon, as everybody knew, was
a famous beauty, a marvel of charm and daintiness, slender, with big,
soulful, wistful eyes. Her marriage to Tracy Edwards, the wealthy
plunger and stockbroker, had been a great social event the year before,
and it was reputed at the time that Edwards had showered her with
jewels and dresses to the wonder and talk even of society.

As for Valerie Fox, I knew she had won quick recognition and even fame
as a dancer in New York during the previous winter, and I recalled
reading three or four days before that she had just returned on the
Kronprinz from a trip abroad.

"I don't suppose you have had time to see Miss Fox," I remarked. "Where
is she?"

"At Beach Park now, I think," replied Waldon, "a resort a few miles
nearer the city on the south shore, where there is a large colony of
actors."

I handed back the letter to Kennedy.

"What do you make of it?" he asked, as he folded it up and put it back
into his pocket.

"I hardly know what to say," I replied. "Of course there have been
rumors, I believe, that all was not exactly like a honeymoon still with
the Tracy Edwardses."

"Yes," returned Waldon slowly, "I know myself that there has been some
trouble, but nothing definite until I found this letter last night in
my sister's room. She never said anything about it either to mother or
myself. They haven't been much together during the summer, and last
night when she disappeared Tracy was in the city. But I hadn't thought
much about it before, for, of course, you know he has large financial
interests that make him keep in pretty close touch with New York and
this summer hasn't been a particularly good one on the stock exchange."

"And," I put in, "a plunger doesn't always make the best of husbands.
Perhaps there is temperament to be reckoned with here."

"There seem to be a good many things to be reckoned with," Craig
considered. "For example, here's a houseboat, the Lucie, a palatial
affair, cruising about aimlessly, with a beautiful woman on it. She
gives a little party, in the absence of her husband, to her brother,
his fiancee and her mother, who visit her from his yacht, the Nautilus.
They break up, those living on the Lucie going to their rooms and the
rest back to the yacht, which is anchored out further in the deeper
water of the bay.

"Some time in the middle of the night her maid, Juanita, finds that she
is not in her room. Her brother is summoned back from his yacht and
finds that she has left this pathetic, unfinished letter. But otherwise
there is no trace of her. Her husband is notified and hurries out
there, but he can find no clue. Meanwhile, Mr. Waldon, in despair,
hurries down to the city to engage me quietly."

"You remember I told you," suggested Waldon, "that my sister hadn't
been feeling well for several days. In fact it seemed that the sea air
wasn't doing her much good, and some one last night suggested that she
try the mountains."

"Had there been anything that would foreshadow the--er--disappearance?"
asked Kennedy.

"Only as I say, that for two or three days she seemed to be listless,
to be sinking by slow and easy stages into a sort of vacant, moody
state of ill health."

"She had a doctor, I suppose?" I asked.

"Yes, Dr. Jermyn, Tracy's own personal physician came down from the
city several days ago."

"What did he say?"

"He simply said that it was congestion of the lungs. As far as he could
see there was no apparent cause for it. I don't think he was very
enthusiastic about the mountain air idea. The fact is he was like a
good many doctors under the circumstances, noncommittal--wanted her
under observation, and all that sort of thing."

"What's your opinion?" I pressed Craig. "Do you think she has run away?"

"Naturally, I'd rather not attempt to say yet," Craig replied
cautiously. "But there are several possibilities. Yes, she might have
left the houseboat in some other boat, of course. Then there is the
possibility of accident. It was a hot night. She might have been
leaning from the window and have lost her balance. I have even thought
of drugs, that she might have taken something in her despondency and
have fallen overboard while under the influence of it. Then, of course,
there are the two deductions that everyone has made already--either
suicide or murder."

Waldon had evidently been turning something over in his mind.

"There was a wireless outfit aboard the houseboat," he ventured at
length.

"What of that?" I asked, wondering why he was changing the subject so
abruptly.

"Why, only this," he replied. "I have been reading about wireless a
good deal lately, and if the theories of some scientists are correct,
the wireless age is not without its dangers as well as its wonders. I
recall reading not long ago of a German professor who says there is no
essential difference between wireless waves and the X-rays, and we know
the terrible physical effects of X-rays. I believe he estimated that
only one three hundred millionth part of the electrical energy
generated by sending a message from one station to another near by is
actually used up in transmitting the message. The rest is dispersed in
the atmosphere. There must be a good deal of such stray electrical
energy about Seaville. Isn't it possible that it might hit some one
somewhere who was susceptible?"

Kennedy said nothing. Waldon's was at least a novel idea, whether it
was plausible or not. The only way to test it out, as far as I could
determine, was to see whether it fitted with the facts after a careful
investigation of the case itself.

It was still early in the day and the trains were not as crowded as
they would be later. Consequently our journey was comfortable enough
and we found ourselves at last at the little vine-covered station at
Seaville.

One could almost feel that the gay summer colony was in a state of
subdued excitement. As we left the quaint station and walked down the
main street to the town wharf where we expected some one would be
waiting for us, it seemed as if the mysterious disappearance of the
beautiful Mrs. Edwards had put a damper on the life of the place. In
the hotels there were knots of people evidently discussing the affair,
for as we passed we could tell by their faces that they recognized us.
One or two bowed and would have joined us, if Waldon had given any
encouragement. But he did not stop, and we kept on down the street
quickly.

I myself began to feel the spell of mystery about the case as I had not
felt it among the distractions of the city. Perhaps I imagined it, but
there even seemed to be something strange about the houseboat which we
could descry at anchor far down the bay as we approached the wharf.

We were met, as Waldon had arranged, by a high-powered runabout, the
tender to his own yacht, a slim little craft of mahogany and brass,
driven like an automobile, and capable of perhaps twenty-five or thirty
miles an hour. We jumped in and were soon skimming over the waters of
the bay like a skipping stone.

It was evident that Waldon was much relieved at having been able to
bring assistance, in which he had as much confidence as he reposed in
Kennedy. At any rate it was something to be nearing the scene of action
again.

The Lucie was perhaps seventy feet long and a most attractive craft,
with a hull yachty in appearance and of a type which could safely make
long runs along the coast, a stanch, seaworthy boat, of course without
the speed of the regularly designed yacht, but more than making up in
comfort for those on board what was lost in that way. Waldon pointed
out with obvious pride his own trim yacht swinging gracefully at anchor
a half mile or so away.

As we approached the houseboat I looked her over carefully. One of the
first things I noticed was that there rose from the roof the primitive
inverted V aerial of a wireless telegraph. I thought immediately of the
unfinished letter and its contents, and shaded my eyes as I took a good
look at the powerful transatlantic station on the spit of sand perhaps
three or four miles distant, with its tall steel masts of the latest
inverted L type and the cluster of little houses below, in which the
operators and the plant were.

Waldon noticed what I was looking at, and remarked, "It's a wonderful
station--and well worth a visit, if you have the time--one of the most
powerful on the coast, I understand."

"How did the Lucie come to be equipped with wireless?" asked Craig
quickly. "It's a little unusual for a private boat."

"Mr. Edwards had it done when she was built," explained Waldon. "His
idea was to use it to keep in touch with the stock market on trips."

"And it has proved effective?" asked Craig.

"Oh, yes--that is, it was all right last winter when he went on a short
cruise down in Florida. This summer he hasn't been on the boat long
enough to use it much."

"Who operates it?"

"He used to hire a licensed operator, although I believe the engineer,
Pedersen, understands the thing pretty well and could use it if
necessary."

"Do you think it was Pedersen who used it for Mrs. Edwards?" asked
Kennedy.

"I really don't know," confessed Waldon. "Pedersen denies absolutely
that he has touched the thing for weeks. I want you to quiz him. I
wasn't able to get him to admit a thing."



CHAPTER VIII

THE HOUSEBOAT MYSTERY


We had by this time swung around to the side of the houseboat. I
realized as we mounted the ladder that the marine gasoline engine had
materially changed the old-time houseboat from a mere scow or barge
with a low flat house on it, moored in a bay or river, and only with
difficulty and expense towed from one place to another. Now the
houseboat was really a fair-sized yacht.

The Lucie was built high in order to give plenty of accommodation for
the living quarters. The staterooms, dining rooms and saloon were
really rooms, with seven or eight feet of head room, and furnished just
as one would find in a tasteful and expensive house.

Down in the hull, of course, was the gasoline motor which drove the
propeller, so that when the owner wanted a change of scene all that was
necessary was to get up anchor, start the motor and navigate the
yacht-houseboat to some other harbor.

Edwards himself met us on the deck. He was a tall man, with a red face,
a man of action, of outdoor life, apparently a hard worker and a hard
player. It was quite evident that he had been waiting for the return of
Waldon anxiously.

"You find us considerably upset, Professor Kennedy," he greeted Craig,
as his brother-in-law introduced us.

Edwards turned and led the way toward the saloon. As he entered and
bade us be seated in the costly cushioned wicker chairs I noticed how
sumptuously it was furnished, and particularly its mechanical piano,
its phonograph and the splendid hardwood floor which seemed to invite
one to dance in the cool breeze that floated across from one set of
open windows to the other. And yet in spite of everything, there was
that indefinable air of something lacking, as in a house from which the
woman is gone.

"You were not here last night, I understand," remarked Kennedy, taking
in the room at a glance.

"Unfortunately, no," replied Edwards, "Business has kept me with my
nose pretty close to the grindstone this summer. Waldon called me up in
the middle of the night, however, and I started down in my car, which
enabled me to get here before the first train. I haven't been able to
do a thing since I got here except just wait--wait--wait. I confess
that I don't know what else to do. Waldon seemed to think we ought to
have some one down here--and I guess he was right. Anyhow, I'm glad to
see you."

I watched Edwards keenly. For the first time I realized that I had
neglected to ask Waldon whether he had seen the unfinished letter. The
question was unnecessary. It was evident that he had not.

"Let me see, Waldon, if I've got this thing straight," Edwards went on,
pacing restlessly up and down the saloon. "Correct me if I haven't.
Last night, as I understand it, there was a sort of little family party
here, you and Miss Verrall and your mother from the Nautilus, and Mrs.
Edwards and Dr. Jermyn."

"Yes," replied Waldon with, I thought, a touch of defiance at the words
"family party." He paused as if he would have added that the Nautilus
would have been more congenial, anyhow, then added, "We danced a little
bit, all except Lucie. She said she wasn't feeling any too well."

Edwards had paused by the door. "If you'll excuse me a minute," he
said, "I'll call Jermyn and Mrs. Edwards' maid, Juanita. You ought to
go over the whole thing immediately, Professor Kennedy."

"Why didn't you say anything about the letter to him?" asked Kennedy
under his breath.

"What was the use?" returned Waldon. "I didn't know how he'd take it.
Besides, I wanted your advice on the whole thing. Do you want to show
it to him?"

"Perhaps it's just as well," ruminated Kennedy. "It may be possible to
clear the thing up without involving anybody's name. At any rate, some
one is coming down the passage this way."

Edwards entered with Dr. Jermyn, a clean-shaven man, youthful in
appearance, yet approaching middle age. I had heard of him before. He
had studied several years abroad and had gained considerable reputation
since his return to America.

Dr. Jermyn shook hands with us cordially enough, made some passing
comment on the tragedy, and stood evidently waiting for us to disclose
our hands.

"You have been Mrs. Edwards' physician for some time, I believe?"
queried Kennedy, fencing for an opening.

"Only since her marriage," replied the doctor briefly.

"She hadn't been feeling well for several days, had she?" ventured
Kennedy again.

"No," replied Dr. Jermyn quickly. "I doubt whether I can add much to
what you already know. I suppose Mr. Waldon has told you about her
illness. The fact is, I suppose her maid Juanita will be able to tell
you really more than I can."

I could not help feeling that Dr. Jermyn showed a great deal of
reluctance in talking.

"You have been with her several days, though, haven't you?"

"Four days, I think. She was complaining of feeling nervous and
telegraphed me to come down here. I came prepared to stay over night,
but Mr. Edwards happened to run down that day, too, and he asked me if
I wouldn't remain longer. My practice in the summer is such that I can
easily leave it with my assistant in the city, so I agreed. Really,
that is about all I can say. I don't know yet what was the matter with
Mrs. Edwards, aside from the nervousness which seemed to be of some
time standing."

He stood facing us, thoughtfully stroking his chin, as a very pretty
and petite maid nervously entered and stood facing us in the doorway.

"Come in, Juanita," encouraged Edwards. "I want you to tell these
gentlemen just what you told me about discovering that Madame had
gone--and anything else that you may recall now."

"It was Juanita who discovered that Madame was gone, you know," put in
Waldon.

"How did you discover it?" prompted Craig.

"It was very hot," replied the maid, "and often on hot nights I would
come in and fan Madame since she was so wakeful. Last night I went to
the door and knocked. There was no reply. I called to her, 'Madame,
madame.' Still there was no answer. The worst I supposed was that she
had fainted. I continued to call."

"The door was locked?" inquired Kennedy.

"Yes, sir. My call aroused the others on the boat. Dr. Jermyn came and
he broke open the door with his shoulder. But the room was empty.
Madame was gone."

"How about the windows?" asked Kennedy.

"Open. They were always open these nights. Sometimes Madame would sit
by the window when there was not much breeze."

"I should like to see the room," remarked Craig, with an inquiring
glance at Edwards.

"Certainly," he answered, leading the way down a corridor.

Mrs. Edwards' room was on the starboard side, with wide windows instead
of portholes. It was furnished magnificently and there was little about
it that suggested the nautical, except the view from the window.

"The bed had not been slept in," Edwards remarked as we looked about
curiously.

Kennedy walked over quickly to the wide series of windows before which
was a leather-cushioned window seat almost level with the window,
several feet above the level of the water. It was by this window,
evidently, that Juanita meant that Mrs. Edwards often sat. It was a
delightful position, but I could readily see that it would be
comparatively easy for anyone accidentally or purposely to fall.

"I think myself," Waldon remarked to Kennedy, "that it must have been
from the open window that she made her way to the outside. It seems
that all agree that the door was locked, while the window was wide
open."

"There had been no sound--no cry to alarm you?" shot out Kennedy
suddenly to Juanita.

"No, sir, nothing. I could not sleep myself, and I thought of Madame."

"You heard nothing?" he asked of Dr. Jermyn.

"Nothing until I heard the maid call," he replied briefly.

Mentally I ran over again Kennedy's first list of possibilities--taken
off by another boat, accident, drugs, suicide, murder.

Was there, I asked myself, sufficient reason for suicide? The letter
seemed to me to show too proud a spirit for that. In fact the last
sentence seemed to show that she was contemplating the surest method of
revenge, rather than surrender. As for accident, why should a person
fall overboard from a large houseboat into a perfectly calm harbor?
Then, too, there had been no outcry. Somehow, I could not seem to fit
any of the theories in with the facts. Evidently it was like many
another case, one in which we, as yet, had insufficient data for a
conclusion.

Suddenly I recalled the theory that Waldon himself had advanced
regarding the wireless, either from the boat itself or from the
wireless station. For the moment, at least, it seemed plausible that
she might have been seated at the window, that she might have been
affected by escaped wireless, or by electrolysis. I knew that some
physicians had described a disease which they attributed to wireless, a
sort of anemia with a marked diminution in the number of red corpuscles
in the blood, due partly to the over etherization of the air by reason
of the alternating currents used to generate the waves.

"I should like now to inspect the little wireless plant you have here
on the Lucie," remarked Kennedy. "I noticed the mast as we were
approaching a few minutes ago."

I had turned at the sound of his voice in time to catch Edwards and Dr.
Jermyn eyeing each other furtively. Did they know about the letter,
after all, I wondered? Was each in doubt about just how much the other
knew?

There was no time to pursue these speculations. "Certainly," agreed Mr.
Edwards promptly, leading the way.

Kennedy seemed keenly interested in inspecting the little wireless
plant, which was of a curious type and not exactly like any that I had
seen before.

"Wireless apparatus," he remarked, as he looked it over, "is divided
into three parts, the source of power whether battery or dynamo, the
making and sending of wireless waves, including the key, spark,
condenser and tuning coil, and the receiving apparatus, head
telephones, antennae, ground and detector."

Pedersen, the engineer, came in while we were looking the plant over,
but seemed uncommunicative to all Kennedy's efforts to engage him in
conversation.

"I see," remarked Kennedy, "that it is a very compact system with
facilities for a quick change from one wave length to another."

"Yes," grunted Pedersen, as averse to talking, evidently, as others on
the Lucie.

"Spark gap, quenched type," I heard Kennedy mutter almost to himself,
with a view to showing Pedersen that he knew something about it. "Break
system relay--operator can overhear any interference while
transmitting--transformation by a single throw of a six-point switch
which tunes the oscillating and open circuits to resonance. Very
clever--very efficient. By the way, Pedersen, are you the only person
aboard who can operate this?"

"How should I know?" he answered almost surlily.

"You ought to know, if anybody," answered Kennedy unruffled. "I know
that it has been operated within the past few days."

Pedersen shrugged his shoulders. "You might ask the others aboard," was
all he said. "Mr. Edwards pays me to operate it only for himself, when
he has no other operator."

Kennedy did not pursue the subject, evidently from fear of saying too
much just at present.

"I wonder if there is anyone else who could have operated it," said
Waldon, as we mounted again to the deck.

"I don't know," replied Kennedy, pausing on the way up. "You haven't a
wireless on the Nautilus, have you?"

Waldon shook his head. "Never had any particular use for it myself," he
answered.

"You say that Miss Verrall and her mother have gone back to the city?"
pursued Kennedy, taking care that as before the others were out of
earshot.

"Yes."

"I'd like to stay with you tonight, then," decided Kennedy. "Might we
go over with you now? There doesn't seem to be anything more I can do
here, unless we get some news about Mrs. Edwards."

Waldon seemed only too glad to agree, and no one on the Lucie insisted
on our staying.

We arrived at the Nautilus a few minutes later, and while we were
lunching Kennedy dispatched the tender to the Marconi station with a
note.

It was early in the afternoon when the tender returned with several
packages and coils of wire. Kennedy immediately set to work on the
Nautilus stretching out some of the wire.

"What is it you are planning?" asked Waldon, to whom every action of
Kennedy seemed to be a mystery of the highest interest.

"Improvising my own wireless," he replied, not averse to talking to the
young man to whom he seemed to have taken a fancy. "For short
distances, you know, it isn't necessary to construct an aerial pole or
even to use outside wires to receive messages. All that is needed is to
use just a few wires stretched inside a room. The rest is just the
apparatus."

I was quite as much interested as Waldon. "In wireless," he went on,
"the signals are not sent in one direction, but in all, so that a
person within range of the ethereal disturbance can get them if only he
has the necessary receiving apparatus. This apparatus need not be so
elaborate and expensive as used to be thought needful if a sensitive
detector is employed, and I have sent over to the station for a new
piece of apparatus which I knew they had in almost any Marconi station.
Why, I've got wireless signals using only twelve feet of number
eighteen copper wire stretched across a room and grounded with a water
pipe. You might even use a wire mattress on an iron bedstead."

"Can't they find out by--er, interference?" I asked, repeating the term
I had so often heard.

Kennedy laughed. "No, not for radio apparatus which merely receives
radiograms and is not equipped for sending. I am setting up only one
side of a wireless outfit here. All I want to do is to hear what is
being said. I don't care about saying anything."

He unwrapped another package which had been loaned to him by the radio
station and we watched him curiously as he tested it and set it up.
Some parts of it I recognized such as the very sensitive microphone,
and another part I could have sworn was a phonograph cylinder, though
Craig was so busy testing his apparatus that now we could not ask
questions.

It was late in the afternoon when he finished, and we had just time to
run up to the dock at Seaville and stop off at the Lucie to see if
anything had happened in the intervening hours before dinner. There was
nothing, except that I found time to file a message to the Star and
meet several fellow newspaper men who had been sent down by other
papers on the chance of picking up a good story.

We had the Nautilus to ourselves, and as she was a very comfortable
little craft, we really had a very congenial time, a plunge over her
side, a good dinner, and then a long talk out on deck under the stars,
in which we went over every phase of the case. As we discussed it,
Waldon followed keenly, and it was quite evident from his remarks that
he had come to the conclusion that Dr. Jermyn at least knew more than
he had told about the case.

Still, the day wore away with no solution yet of the mystery.



CHAPTER IX

THE RADIO DETECTIVE


It was early the following morning when a launch drew up beside the
Nautilus. In it were Edwards and Dr. Jermyn, wildly excited.

"What's the matter?" called out Waldon.

"They--they have found the body," Edwards blurted out.

Waldon paled and clutched the rail. He had thought the world of his
sister, and not until the last moment had he given up hope that perhaps
she might be found to have disappeared in some other way than had
become increasingly evident.

"Where?" cried Kennedy. "Who?"

"Over on Ten Mile Beach," answered Edwards. "Some fishermen who had
been out on a cruise and hadn't heard the story. They took the body to
town, and there it was recognized. They sent word out to us
immediately."

Waldon had already spun the engine of his tender, which was about the
fastest thing afloat about Seaville, had taken Edwards over, and we
were off in a cloud of spray, the nose of the boat many inches above
the surface of the water.

In the little undertaking establishment at Seaville lay the body of the
beautiful young matron about whom so much anxiety had been felt. I
could not help thinking what an end was this for the incomparable
beauty. At the very height of her brief career the poor little woman's
life had been suddenly snuffed out. But by what? The body had been
found, but the mystery had been far from solved.

As Kennedy bent over the body, I heard him murmur to himself, "She had
everything--everything except happiness."

"Was it drowning that caused her death?" asked Kennedy of the local
doctor, who also happened to be coroner and had already arrived on the
scene.

The doctor shook his head. "I don't know," he said doubtfully. "There
was congestion of the lungs--but I--I can't say but what she might have
been dead before she fell or was thrown into the water."

Dr. Jermyn stood on one side, now and then putting in a word, but for
the most part silent unless spoken to. Kennedy, however, was making a
most minute examination.

As he turned the beautiful head, almost reverently, he saw something
that evidently attracted his attention. I was standing next to him and,
between us, I think we cut off the view of the others. There on the
back of the neck, carefully, had been smeared something transparent,
almost skin-like, which had easily escaped the attention of the rest.

Kennedy tried to pick it off, but only succeeded in pulling off a very
minute piece to which the flesh seemed to adhere.

"That's queer," he whispered to me. "Water, naturally, has no effect on
it, else it would have been washed off long before. Walter," he added,
"just slip across the street quietly to the drug store and get me a
piece of gauze soaked with acetone."

As quickly and unostentatiously as I could I did so and handed him the
wet cloth, contriving at the same time to add Waldon to our barrier,
for I could see that Kennedy was anxious to be observed as little as
possible.

"What is it?" I whispered, as he rubbed the transparent skin-like stuff
off, and dropped the gauze into his pocket.

"A sort of skin varnish," he remarked under his breath, "waterproof and
so adhesive that it resists pulling off even with a knife without
taking the cuticle with it."

Beneath, as the skin varnish slowly dissolved under his gentle rubbing,
he had disclosed several very small reddish spots, like little cuts
that had been made by means of a very sharp instrument. As he did so,
he gave them a hasty glance, turned the now stony beautiful head
straight again, stood up, and resumed his talk with the coroner, who
was evidently getting more and more bewildered by the case.

Edwards, who had completed the arrangements with the undertaker for the
care of the body as soon as the coroner released it, seemed completely
unnerved.

"Jermyn," he said to the doctor, as he turned away and hid his eyes, "I
can't stand this. The undertaker wants some stuff from the--er--boat,"
his voice broke over the name which had been hers. "Will you get it for
me? I'm going up to a hotel here, and I'll wait for you there. But I
can't go out to the boat--yet."

"I think Mr. Waldon will be glad to take you out in his tender,"
suggested Kennedy. "Besides, I feel that I'd like a little fresh air as
a bracer, too, after such a shock."

"What were those little cuts?" I asked as Waldon and Dr. Jermyn
preceded us through the crowd outside to the pier.

"Some one," he answered in a low tone, "has severed the pneumogastric
nerves."

"The pneumogastric nerves?" I repeated.

"Yes, the vagus or wandering nerve, the so-called tenth cranial nerve.
Unlike the other cranial nerves, which are concerned with the special
senses or distributed to the skin and muscles of the head and neck, the
vagus, as its name implies, strays downward into the chest and abdomen
supplying branches to the throat, lungs, heart and stomach and forms an
important connecting link between the brain and the sympathetic nervous
system."

We had reached the pier, and a nod from Kennedy discouraged further
conversation on the subject.

A few minutes later we had reached the Lucie and gone up over her side.
Kennedy waited until Jermyn had disappeared into the room of Mrs.
Edwards to get what the undertaker had desired. A moment and he had
passed quietly into Dr. Jermyn's own room, followed by me. Several
quick glances about told him what not to waste time over, and at last
his eye fell on a little portable case of medicines and surgical
instruments. He opened it quickly and took out a bottle of golden
yellow liquid.

Kennedy smelled it, then quickly painted some on the back of his hand.
It dried quickly, like an artificial skin. He had found a bottle of
skin varnish in Dr. Jermyn's own medicine chest!

We hurried back to the deck, and a few minutes later the doctor
appeared with a large package.

"Did you ever hear of coating the skin by a substance which is
impervious to water, smooth and elastic?" asked Kennedy quietly as
Waldon's tender sped along back to Seaville.

"Why--er, yes," he said frankly, raising his eyes and looking at Craig
in surprise. "There have been a dozen or more such substances. The best
is one which I use, made of pyroxylin, the soluble cotton of commerce,
dissolved in amyl acetate and acetone with some other substances that
make it perfectly sterile. Why do you ask?"

"Because some one has used a little bit of it to cover a few slight
cuts on the back of the neck of Mrs. Edwards."

"Indeed?" he said simply, in a tone of mild surprise.

"Yes," pursued Kennedy. "They seem to me to be subcutaneous incisions
of the neck with a very fine scalpel dividing the two great
pneumogastric nerves. Of course you know what that would mean--the
victim would pass away naturally by slow and easy stages in three or
four days, and all that would appear might be congestion of the lungs.
They are delicate little punctures and elusive nerves to locate, but
after all it might be done as painlessly, as simply and as safely as a
barber might remove some dead hairs. A country coroner might easily
pass over such evidence at an autopsy--especially if it was concealed
by skin varnish."

I was surprised at the frankness with which Kennedy spoke, but
absolutely amazed at the coolness of Jermyn. At first he said
absolutely nothing. He seemed to be as set in his reticence as he had
been when we first met.

I watched him narrowly. Waldon, who was driving the boat, had not heard
what was said, but I had, and I could not conceive how anyone could
take it so calmly.

Finally Jermyn turned to Kennedy and looked him squarely in the eye.
"Kennedy," he said slowly, "this is extraordinary--most extraordinary,"
then, pausing, added, "if true."

"There can be no doubt of the truth," replied Kennedy, eyeing Dr.
Jermyn just as squarely.

"What do you propose to do about it?" asked the doctor.

"Investigate," replied Kennedy simply. "While Waldon takes these things
up to the undertaker's, we may as well wait here in the boat. I want
him to stop on the way back for Mr. Edwards. Then we shall go out to
the Lucie. He must go, whether he likes it or not."

It was indeed a most peculiar situation as Kennedy and I sat in the
tender with Dr. Jermyn waiting for Waldon to return with Edwards. Not a
word was spoken.

The tenseness of the situation was not relieved by the return of Waldon
with Edwards. Waldon seemed to realize without knowing just what it
was, that something was about to happen. He drove his boat back to the
Lucie again in record time. This was Kennedy's turn to be reticent.
Whatever it was he was revolving in his mind, he answered in scarcely
more than monosyllables whatever questions were put to him.

"You are not coming aboard?" inquired Edwards in surprise as he and
Jermyn mounted the steps of the houseboat ladder, and Kennedy remained
seated in the tender.

"Not yet," replied Craig coolly.

"But I thought you had something to show me. Waldon told me you had."

"I think I shall have in a short time," returned Kennedy. "We shall be
back immediately. I'm just going to ask Waldon to run over to the
Nautilus for a few minutes. We'll tow back your launch, too, in case
you need it."

Waldon had cast off obediently.

"There's one thing sure," I remarked. "Jermyn can't get away from the
Lucie until we return--unless he swims."

Kennedy did not seem to pay much attention to the remark, for his only
reply was: "I'm taking a chance by this maneuvering, but I think it
will work out that I am correct. By the way, Waldon, you needn't put on
so much speed. I'm in no great hurry to get back. Half an hour will be
time enough."

"Jermyn? What did you mean by Jermyn?" asked Waldon, as we climbed to
the deck of the Nautilus.

He had evidently learned, as I had, that it was little use to try to
quiz Kennedy until he was ready to be questioned and had decided to try
it on me.

I had nothing to conceal and I told him quite fully all that I knew.
Actually, I believe if Jermyn had been there, it would have taken both
Kennedy and myself to prevent violence. As it was I had a veritable
madman to deal with while Kennedy gathered up leisurely the wireless
outfit he had installed on the deck of Waldon's yacht. It was only by
telling him that I would certainly demand that Kennedy leave him behind
if he did not control his feelings that I could calm him before Craig
had finished his work on the yacht.

Waldon relieved himself by driving the tender back at top speed to the
Lucie, and now it seemed that Kennedy had no objection to traveling as
fast as the many-cylindered engine was capable of going.

As we entered the saloon of the houseboat, I kept close watch over
Waldon.

Kennedy began by slipping a record on the phonograph in the corner of
the saloon, then facing us and addressing Edwards particularly.

"You may be interested to know, Mr. Edwards," he said, "that your
wireless outfit here has been put to a use for which you never intended
it."

No one said anything, but I am sure that some one in the room then for
the first time began to suspect what was coming.

"As you know, by the use of an aerial pole, messages may be easily
received from any number of stations," continued Craig. "Laws, rules
and regulations may be adopted to shut out interlopers and plug
busybody ears, but the greater part of whatever is transmitted by the
Hertzian waves can be snatched down by other wireless apparatus.

"Down below, in that little room of yours," went on Craig, "might sit
an operator with his ear-phone clamped to his head, drinking in the
news conveyed surely and swiftly to him through the wireless
signals--plucking from the sky secrets of finance and," he added,
leaning forward, "love."

In his usual dramatic manner Kennedy had swung his little audience
completely with him.

"In other words," he resumed, "it might be used for eavesdropping by a
wireless wiretapper. Now," he concluded, "I thought that if there was
any radio detective work being done, I might as well do some, too."

He toyed for a moment with the phonograph record. "I have used," he
explained, "Marconi's radiotelephone, because in connection with his
receivers Marconi uses phonographic recorders and on them has captured
wireless telegraph signals over hundreds of miles.

"He has found that it is possible to receive wireless signals, although
ordinary records are not loud enough, by using a small microphone on
the repeating diaphragm and connected with a loud-speaking telephone.
The chief difficulty was to get a microphone that would carry a
sufficient current without burning up. There were other difficulties,
but they have been surmounted and now wireless telegraph messages may
be automatically recorded and made audible."

Kennedy started the phonograph, running it along, stopping it, taking
up the record at a new point.

"Listen," he exclaimed at length, "there's something interesting, the
WXY call--Seaville station--from some one on the Lucie only a few
minutes ago, sending a message to be relayed by Seaville to the station
at Beach Park. It seems impossible, but buzzing and ticking forth is
this message from some one off this very houseboat. It reads: "Miss
Valerie Fox, Beach Park. I am suspected of the murder of Mrs. Edwards.
I appeal to you to help me. You must allow me to tell the truth about
the messages I intercepted for Mrs. Edwards which passed between
yourself on the ocean and Mr. Edwards in New York via Seaville. You
rejected me and would not let me save you. Now you must save me."

Kennedy paused, then added, "The message is signed by Dr. Jermyn!"

At once I saw it all. Jermyn had been the unsuccessful suitor for Miss
Fox's affections. But before I could piece out the rest of the tragic
story, Kennedy had started the phonograph record at an earlier point
which he had skipped for the present.

"Here's another record--a brief one--also to Valerie Fox from the
houseboat: 'Refuse all interviews. Deny everything. Will see you as
soon as present excitement dies down.'"

Before Kennedy could finish, Waldon had leaped forward, unable longer
to control his feelings. If Kennedy had not seized his arm, I verily
believe he would have cast Dr. Jermyn into the bay into which his
sister had fallen two nights before in her terribly weakened condition.

"Waldon," cried Kennedy, "for God's sake, man--wait! Don't you
understand? The second message is signed Tracy Edwards."

It came as quite as much a shock of surprise to me as to Waldon.

"Don't you understand?" he repeated. "Your sister first learned from
Dr. Jermyn what was going on. She moved the Lucie down here near
Seaville in order to be near the wireless station when the ship bearing
her rival, Valerie Fox, got in touch with land. With the help of Dr.
Jermyn she intercepted the wireless messages from the Kronprinz to the
shore--between her husband and Valerie Fox."

Kennedy was hurrying on now to his irresistible conclusion. "She found
that he was infatuated with the famous stage beauty, that he was
planning to marry another, her rival. She accused him of it, threatened
to defeat his plans. He knew she knew his unfaithfulness. Instead of
being your sister's murderer, Dr. Jermyn was helping her get the
evidence that would save both her and perhaps win Miss Fox back to
himself."

Kennedy had turned sharply on Edwards.

"But," he added, with a glance that crushed any lingering hope that the
truth had been concealed, "the same night that Dr. Jermyn arrived here,
you visited your wife. As she slept you severed the nerves that meant
life or death to her. Then you covered the cuts with the preparation
which you knew Dr. Jermyn used. You asked him to stay, while you went
away, thinking that when death came you would have a perfect
alibi--perhaps a scapegoat. Edwards, the radio detective convicts you!"



CHAPTER X

THE CURIO SHOP


Edwards crumpled up as Kennedy and I faced him. There was no escape. In
fact our greatest difficulty was to protect him from Waldon.

Kennedy's work in the case was over when we had got Edwards ashore and
in the hands of the authorities. But mine had just begun and it was
late when I got my story on the wire for the Star.

I felt pretty tired and determined to make up for it by sleeping the
next day. It was no use, however.

"Why, what's the matter, Mrs. Northrop?" I heard Kennedy ask as he
opened our door the next morning, just as I had finished dressing.

He had admitted a young woman, who greeted us with nervous,
wide-staring eyes.

"It's--it's about Archer," she cried, sinking into the nearest chair
and staring from one to the other of us.

She was the wife of Professor Archer Northrop, director of the
archeological department at the university. Both Craig and I had known
her ever since her marriage to Northrop, for she was one of the most
attractive ladies in the younger set of the faculty, to which Craig
naturally belonged. Archer had been of the class below us in the
university. We had hazed him, and out of the mild hazing there had,
strangely enough, grown a strong friendship.

I recollected quickly that Northrop, according to last reports, had
been down in the south of Mexico on an archeological expedition. But
before I could frame, even in my mind, the natural question in a form
that would not alarm his wife further, Kennedy had it on his lips.

"No bad news from Mitla, I hope?" he asked gently, recalling one of the
main working stations chosen by the expedition and the reported
unsettled condition of the country about it. She looked up quickly.

"Didn't you know--he--came back from Vera Cruz yesterday?" she asked
slowly, then added, speaking in a broken tone, "and--he
seems--suddenly--to have disappeared. Oh, such a terrible night of
worry! No word--and I called up the museum, but Doctor Bernardo, the
curator, had gone, and no one answered. And this morning--I couldn't
stand it any longer--so I came to you."

"You have no idea, I suppose, of anything that was weighing on his
mind?" suggested Kennedy.

"No," she answered promptly.

In default of any further information, Kennedy did not pursue this line
of questioning. I could not determine from his face or manner whether
he thought the matter might involve another than Mrs. Northrop, or,
perhaps, something connected with the unsettled condition of the
country from which her husband had just arrived.

"Have you any of the letters that Archer wrote home?" asked Craig, at
length.

"Yes," she replied eagerly, taking a little packet from her handbag. "I
thought you might ask that. I brought them."

"You are an ideal client," commented Craig encouragingly, taking the
letters. "Now, Mrs. Northrop, be brave. Trust me to run this thing
down, and if you hear anything let me know immediately."

She left us a moment later, visibly relieved.

Scarcely had she gone when Craig, stuffing the letters into his pocket
unread, seized his hat, and a moment later was striding along toward
the museum with his habitual rapid, abstracted step which told me that
he sensed a mystery.

In the museum we met Doctor Bernardo, a man slightly older than
Northrop, with whom he had been very intimate. He had just arrived and
was already deeply immersed in the study of some new and beautiful
colored plates from the National Museum of Mexico City.

"Do you remember seeing Northrop here yesterday afternoon?" greeted
Craig, without explaining what had happened.

"Yes," he answered promptly. "I was here with him until very late. At
least, he was in his own room, working hard, when I left."

"Did you see him go?"

"Why--er--no," replied Bernardo, as if that were a new idea. "I left
him here--at least, I didn't see him go out."

Kennedy tried the door of Northrop's room, which was at the far end, in
a corner, and communicated with the hall only through the main floor of
the museum. It was locked. A pass-key from the janitor quickly opened
it.

Such a sight as greeted us, I shall never forget. There, in his big
desk-chair, sat Northrop, absolutely rigid, the most horribly contorted
look on his features that I have ever seen--half of pain, half of fear,
as if of something nameless.

Kennedy bent over. His hands were cold.

Northrop had been dead at least twelve hours, perhaps longer. All night
the deserted museum had guarded its terrible secret.

As Craig peered into his face, he saw, in the fleshy part of the neck,
just below the left ear, a round red mark, with just a drop or two of
now black coagulated blood in the center. All around we could see a
vast amount of miscellaneous stuff, partly unpacked, partly just
opened, and waiting to be taken out of the wrappings by the now
motionless hands.

"I suppose you are more or less familiar with what Northrop brought
back?" asked Kennedy of Bernardo, running his eye over the material in
the room.

"Yes, reasonably," answered Bernardo. "Before the cases arrived from
the wharf, he told me in detail what he had managed to bring up with
him."

"I wish, then, that you would look it over and see if there is anything
missing," requested Craig, already himself busy in going over the room
for other evidence.

Doctor Bernardo hastily began taking a mental inventory of the stuff.
While they worked, I tried vainly to frame some theory which would
explain the startling facts we had so suddenly discovered.

Mitla, I knew, was south of the city of Oaxaca, and there, in its
ruined palaces, was the crowning achievement of the old Zapotec kings.
No ruins in America were more elaborately ornamented or richer in lore
for the archeologist.

Northrop had brought up porphyry blocks with quaint grecques and much
hieroglyphic painting. Already unpacked were half a dozen copper axes,
some of the first of that particular style that had ever been brought
to the United States. Besides the sculptured stones and the mosaics
were jugs, cups, vases, little gods, sacrificial stones--enough,
almost, to equip a new alcove in the museum.

Before Northrop was an idol, a hideous thing on which frogs and snakes
squatted and coiled. It was a fitting piece to accompany the gruesome
occupant of the little room in his long, last vigil. In fact, it almost
sent a shudder over me, and if I had been inclined to the
superstitious, I should certainly have concluded that this was
retribution for having disturbed the lares and penates of a dead race.

Doctor Bernardo was going over the material a second time. By the look
on his face, even I could guess that something was missing.

"What is it?" asked Craig, following the curator closely.

"Why," he answered slowly, "there was an inscription--we were looking
at it earlier in the day--on a small block of porphyry. I don't see it."

He paused and went back to his search before we could ask him further
what he thought the inscription was about.

I thought nothing myself at the time of his reticence, for Kennedy had
gone over to a window back of Northrop and to the left. It was fully
twenty feet from the downward slope of the campus there, and, as he
craned his neck out, he noted that the copper leader of the rain pipe
ran past it a few feet away.

I, too, looked out. A thick group of trees hid the window from the
avenue beyond the campus wall, and below us, at a corner of the
building, was a clump of rhododendrons. As Craig bent over the sill, he
whipped out a pocket lens.

A moment later he silently handed the glass to me. As nearly as I could
make out, there were five marks on the dust of the sill.

"Finger-prints!" I exclaimed. "Some one has been clinging to the edge
of the ledge."

"In that case," Craig observed quietly, "there would have been only
four prints."

I looked again, puzzled. The prints were flat and well separated.

"No," he added, "not finger-prints--toe-prints."

"Toe-prints?" I echoed.

Before he could reply, Craig had dashed out of the room, around, and
under the window. There, he was carefully going over the soft earth
around the bushes below.

"What are you looking for?" I asked, joining him.

"Some one--perhaps two--has been here," he remarked, almost under his
breath. "One, at least, has removed his shoes. See those shoe-prints up
to this point? The print of a boot-heel in soft earth shows the
position and contour of every nail head. Bertillon has made a
collection of such nails, certain types, sizes, and shapes used in
certain boots, showing often what country the shoes came from. Even the
number and pattern are significant. Some factories use a fixed number
of nails and arrange them in a particular manner. I have made my own
collection of such prints in this country. These were American shoes.
Perhaps the clue will not lead us anywhere, though, for I doubt whether
it was an American foot."

Kennedy continued to study the marks.

"He removed his shoes--either to help in climbing or to prevent
noise--ah--here's the foot! Strange--see how small it is--and broad,
how prehensile the toes--almost like fingers. Surely that foot could
never have been encased in American shoes all its life. I shall make
plaster casts of these, to preserve later."

He was still scouting about on hands and knees in the dampness of the
rhododendrons. Suddenly he reached his long arm in among the shrubs and
picked up a little reed stick. On the end of it was a small cylinder of
buff brown.

He looked at it curiously, dug his nail into the soft mass, then rubbed
his nail over the tip of his tongue gingerly.

With a wry face, as if the taste were extremely acrid, he moistened his
handkerchief and wiped off his tongue vigorously.

"Even that minute particle that was on my nail makes my tongue tingle
and feel numb," he remarked, still rubbing. "Let us go back again. I
want to see Bernardo."

"Had he any visitors during the day?" queried Kennedy, as he reentered
the ghastly little room, while the curator stood outside, completely
unnerved by the tragedy which had been so close to him without his
apparently knowing it. Kennedy was squeezing out from the little wound
on Northrop's neck a few drops of liquid on a sterilized piece of glass.

"No; no one," Bernardo answered, after a moment.

"Did you see anyone in the museum who looked suspicious?" asked
Kennedy, watching Bernardo's face keenly.

"No," he hesitated. "There were several people wandering about among
the exhibits, of course. One, I recall, late in the afternoon, was a
little dark-skinned woman, rather good-looking."

"A Mexican?"

"Yes, I should say so. Not of Spanish descent, though. She was rather
of the Indian type. She seemed to be much interested in the various
exhibits, asked me several questions, very intelligently, too. Really,
I thought she was trying to--er--flirt with me."

He shot a glance at Craig, half of confession, half of embarrassment.

"And--oh, yes--there was another--a man, a little man, as I recall,
with shaggy hair. He looked like a Russian to me. I remember, because
he came to the door, peered around hastily, and went away. I thought he
might have got into the wrong part of the building and went to direct
him right--but before I could get out into the hall, he was gone. I
remember, too, that, as I turned, the woman had followed me and soon
was asking other questions--which, I will admit--I was glad to answer."

"Was Northrop in his room while these people were here?"

"Yes; he had locked the door so that none of the students or visitors
could disturb him."

"Evidently the woman was diverting your attention while the man entered
Northrop's room by the window," ruminated Craig, as we stood for a
moment in the outside doorway.

He had already telephoned to our old friend Doctor Leslie, the coroner,
to take charge of the case, and now was ready to leave. The news had
spread, and the janitor of the building was waiting to lock the campus
door to keep back the crowd of students and others.

Our next duty was the painful one of breaking the news to Mrs.
Northrop. I shall pass it over. Perhaps no one could have done it more
gently than Kennedy. She did not cry. She was simply dazed. Fortunately
her mother was with her, had been, in fact, ever since Northrop had
gone on the expedition.

"Why should anyone want to steal tablets of old Mixtec inscriptions?" I
asked thoughtfully, as we walked sadly over the campus in the direction
of the chemistry building. "Have they a sufficient value, even on
appreciative Fifth Avenue, to warrant murder?"

"Well," he remarked, "it does seem incomprehensible. Yet people do just
such things. The psychologists tell us that there is a veritable mania
for possessing such curios. However, it is possible that there may be
some deeper significance in this case," he added, his face puckered in
thought.

Who was the mysterious Mexican woman, who the shaggy Russian? I asked
myself. Clearly, at least, if she existed at all, she was one of the
millions not of Spanish but of Indian descent in the country south of
us. As I reasoned it out, it seemed to me as if she must have been an
accomplice. She could not have got into Northrop's room either before
or after Doctor Bernardo left. Then, too, the toe-and shoe-prints were
not hers. But, I figured, she certainly had a part in the plot.

While I was engaged in the vain effort to unravel the tragic affair by
pure reason, Kennedy was at work with practical science.

He began by examining the little dark cylinder on the end of the reed.
On a piece of the stuff, broken off, he poured a dark liquid from a
brown-glass bottle. Then he placed it under a microscope.

"Microscopically," he said slowly, "it consists almost wholly of
minute, clear granules which give a blue reaction with iodine. They are
starch. Mixed with them are some larger starch granules, a few plant
cells, fibrous matter, and other foreign particles. And then, there is
the substance that gives that acrid, numbing taste." He appeared to be
vacantly studying the floor.

"What do you think it is?" I asked, unable to restrain myself.

"Aconite," he answered slowly, "of which the active principle is the
deadly poisonous alkaloid, aconitin."

He walked over and pulled down a well-thumbed standard work on
toxicology, turned the pages, then began to read aloud:

Pure aconitin is probably the most actively poisonous substance with
which we are acquainted and, if administered hypodermically, the
alkaloid is even more powerfully poisonous than when taken by the mouth.

As in the case of most of the poisonous alkaloids, aconitin does not
produce any decidedly characteristic post-mortem appearances. There is
no way to distinguish it from other alkaloids, in fact, no reliable
chemical test. The physiological effects before death are all that can
be relied on.

Owing to its exceeding toxic nature, the smallness of the dose required
to produce death, and the lack of tests for recognition, aconitin
possesses rather more interest in legal medicine than most other
poisons.

It is one of the few substances which, in the present state of
toxicology, might be criminally administered and leave no positive
evidence of the crime. If a small but fatal dose of the poison were to
be given, especially if it were administered hypodermically, the
chances of its detection in the body after death would be practically
none.



CHAPTER XI

THE "PILLAR OF DEATH"


I was looking at him fixedly as the diabolical nature of what must have
happened sank into my mind. Here was a poison that defied detection. I
could see by the look on Craig's face that that problem, alone, was
enough to absorb his attention. He seemed fully to realize that we had
to deal with a criminal so clever that he might never be brought to
justice.

An idea flashed over me.

"How about the letters?" I suggested.

"Good, Walter!" he exclaimed.

He untied the package which Mrs. Northrop had given him and glanced
quickly over one after another of the letters.

"Ah!" he exclaimed, fairly devouring one dated at Mitla. "Listen--it
tells about Northrop's work and goes on:

"'I have been much interested in a cavern, or subterraneo, here, in the
shape of a cross, each arm of which extends for some twelve feet
underground. In the center it is guarded by a block of stone popularly
called "the Pillar of Death." There is a superstition that whoever
embraces it will die before the sun goes down.

"'From the subterraneo is said to lead a long, underground passage
across the court to another subterranean chamber which is full of
Mixtec treasure. Treasure hunters have dug all around it, and it is
said that two old Indians, only, know of the immense amount of buried
gold and silver, but that they will not reveal it.'"

I started up. Here was the missing link which I had been waiting for.

"There, at least, is the motive," I blurted out. "That is why Bernardo
was so reticent. Northrop, in his innocence of heart, had showed him
that inscription."

Kennedy said nothing as he finally tied up the little packet of letters
and locked it in his safe. He was not given to hasty generalizations;
neither was he one who clung doggedly to a preconceived theory.

It was still early in the afternoon. Craig and I decided to drop into
the museum again in order to see Doctor Bernardo. He was not there and
we sat down to wait.

Just then the letter box in the door clicked. It was the postman on his
rounds. Kennedy walked over and picked up the letter.

The postmark bore the words, "Mexico City," and a date somewhat later
than that on which Northrop had left Vera Cruz. In the lower corner,
underscored, were the words, "Personal--Urgent."

"I'd like to know what is in that," remarked Craig, turning it over and
over.

He appeared to be considering something, for he rose suddenly and
shoved the letter into his pocket.

I followed, and a few moments later, across the campus in his
laboratory, he was working quickly over an X-ray apparatus. He had
placed the letter in it.

"These are what are known as 'low' tubes," he explained. "They give out
'soft rays.'" He continued to work for a few moments, then handed me
the letter.

"Now, Walter," he said, "if you will just hurry back to the museum and
replace that letter, I think I will have something that will astonish
you--though whether it will have any bearing on the case, remains to be
seen."

"What is it?" I asked, a few minutes later, when I had rejoined him,
after returning the letter. He was poring intently over what looked
like a negative.

"The possibility of reading the contents of documents inclosed in a
sealed envelope," he replied, still studying the shadowgraph closely,
"has already been established by the well-known English scientist,
Doctor Hall Edwards. He has been experimenting with the method of using
X-rays recently discovered by a German scientist, by which radiographs
of very thin substances, such as a sheet of paper, a leaf, an insect's
body, may be obtained. These thin substances through which the rays
used formerly to pass without leaving an impression, can now be
radiographed."

I looked carefully as he traced out something on the negative. On it
was easily possible, following his guidance, to read the words
inscribed on the sheet of paper inside. So admirably defined were all
the details that even the gum on the envelope and the edges of the
sheet of paper inside the envelope could be distinguished.

"Any letter written with ink having a mineral basis can be
radiographed," added Craig. "Even when the sheet is folded in the usual
way, it is possible by taking a radiograph stereoscopically, to
distinguish the writing, every detail standing out in relief. Besides,
it can be greatly magnified, which aids in deciphering it if it is
indistinct or jumbled up. Some of it looks like mirror writing. Ah," he
added, "here's something interesting!"

Together we managed to trace out the contents of several paragraphs, of
which the significant parts were as follows:

 I am expecting that my friend Senora Herreria will be in New York
by the time you receive this, and should she call on you, I know you
will accord her every courtesy. She has been in Mexico City for a few
days, having just returned from Mitla, where she met Professor
Northrop. It is rumored that Professor Northrop has succeeded in
smuggling out of the country a very important stone bearing an
inscription which, I understand, is of more than ordinary interest. I
do not know anything definite about it, as Senora Herreria is very
reticent on the matter, but depend on you to find out if possible and
let me know of it.

According to the rumors and the statements of the senora, it seems that
Northrop has taken an unfair advantage of the situation down in Oaxaca,
and I suppose she and others who know about the inscription feel that
it is really the possession of the government.

You will find that the senora is an accomplished antiquarian and
scholar. Like many others down here just now, she has a high regard for
the Japanese. As you know, there exists a natural sympathy between some
Mexicans and Japanese, owing to what is believed to be a common origin
of the two races.

In spite of the assertions of many to the contrary, there is little
doubt left in the minds of students that the Indian races which have
peopled Mexico were of Mongolian stock. Many words in some dialects are
easily understood by Chinese immigrants. A secretary of the Japanese
legation here was able recently to decipher old Mixtec inscriptions
found in the ruins of Mitla.

Senora Herreria has been much interested in establishing the
relationship and, I understand, is acquainted with a Japanese curio
dealer in New York who recently visited Mexico for the same purpose. I
believe that she wishes to collaborate with him on a monograph on the
subject, which is expected to have a powerful effect on the public
opinion both here and at Tokyo.

In regard to the inscription which Northrop has taken with him, I rely
on you to keep me informed. There seems to be a great deal of mystery
connected with it, and I am simply hazarding a guess as to its nature.
If it should prove to be something which might interest either the
Japanese or ourselves, you can see how important it may be, especially
in view of the forthcoming mission of General Francisco to Tokyo.

Very sincerely yours,

DR. EMILIO SANCHEZ, Director.

"Bernardo is a Mexican," I exclaimed, as Kennedy finished reading, "and
there can be no doubt that the woman he mentioned was this Senora
Herreria."

Kennedy said nothing, but seemed to be weighing the various paragraphs
in the letter.

"Still," I observed, "so far, the only one against whom we have any
direct suspicion in the case is the shaggy Russian, whoever he is."

"A man whom Bernardo says looked like a Russian," corrected Craig.

He was pacing the laboratory restlessly.

"This is becoming quite an international affair," he remarked finally,
pausing before me, his hat on. "Would you like to relax your mind by a
little excursion among the curio shops of the city? I know something
about Japanese curios--more, perhaps, than I do of Mexican. It may
amuse us, even if it doesn't help in solving the mystery. Meanwhile, I
shall make arrangements for shadowing Bernardo. I want to know just how
he acts after he reads that letter."

He paused long enough to telephone his instructions to an uptown
detective agency which could be depended on for such mere routine work,
then joined me with the significant remark: "Blood is thicker than
water, anyhow, Walter. Still, even if the Mexicans are influenced by
sentiment, I hardly think that would account for the interest of our
friends from across the water in the matter."

I do not know how many of the large and small curio shops of the city
we visited that afternoon. At another time, I should have enjoyed the
visits immensely, for anyone seeking articles of beauty will find the
antique shops of Fifth and Fourth Avenues and the side streets well
worth visiting.

We came, at length, to one, a small, quaint, dusty rookery, down in a
basement, entered almost directly from the street. It bore over the
door a little gilt sign which read simply, "Sato's."

As we entered, I could not help being impressed by the wealth of
articles in beautiful cloisonne enamel, in mother-of-pearl, lacquer,
and champleve. There were beautiful little koros, or incense burners,
vases, and teapots. There were enamels incrusted, translucent, and
painted, works of the famous Namikawa, of Kyoto, and Namikawa, of
Tokyo. Satsuma vases, splendid and rare examples of the potter's art,
crowded gorgeously embroidered screens depicting all sorts of brilliant
scenes, among others the sacred Fujiyama rising in the stately
distance. Sato himself greeted us with a ready smile and bow.

"I am just looking for a few things to add to my den," explained
Kennedy, adding, "nothing in particular, but merely whatever happens to
strike my fancy."

"Surely, then, you have come to the right shop," greeted Sato. "If
there is anything that interests you, I shall be glad to show it."

"Thank you," replied Craig. "Don't let me trouble you with your other
customers. I will call on you if I see anything."

For several minutes, Craig and I busied ourselves looking about, and we
did not have to feign interest, either.

"Often things are not as represented," he whispered to me, after a
while, "but a connoiseur can tell spurious goods. These are the real
thing, mostly."

"Not one in fifty can tell the difference," put in the voice of Sato,
at his elbow.

"Well, you see I happen to know," Craig replied, not the least
disconcerted. "You can't always be too sure."

A laugh and a shrug was Sato's answer. "It's well all are not so keen,"
he said, with a frank acknowledgment that he was not above sharp
practices.

I glanced now and then at the expressionless face of the curio dealer.
Was it merely the natural blankness of his countenance that impressed
me, or was there, in fact, something deep and dark hidden in it,
something of "East is East and West is West" which I did not and could
not understand? Craig was admiring the bronzes. He had paused before
one, a square metal fire-screen of odd design, with the title on a
card, "Japan Gazing at the World."

It represented Japan as an eagle, with beak and talons of burnished
gold, resting on a rocky island about which great waves dashed. The
bird had an air of dignity and conscious pride in its strength, as it
looked out at the world, a globe revolving in space.

"Do you suppose there is anything significant in that?" I asked,
pointing to the continent of North America, also in gold and
prominently in view.

"Ah, honorable sir," answered Sato, before Kennedy could reply, "the
artist intended by that to indicate Japan's friendliness for America
and America's greatness."

He was inscrutable. It seemed as if he were watching our every move,
and yet it was done with a polite cordiality that could not give
offense.

Behind some bronzes of the Japanese Hercules destroying the demons and
other mythical heroes was a large alcove, or tokonoma, decorated with
peacock, stork, and crane panels. Carvings and lacquer added to the
beauty of it. A miniature chrysanthemum garden heightened the illusion.
Carved hinoki wood framed the panels, and the roof was supported by
columns in the old Japanese style, the whole being a compromise between
the very simple and quiet and the polychromatic. The dark woods, the
lanterns, the floor tiles of dark red, and the cushions of rich gold
and yellow were most alluring. It had the genuine fascination of the
Orient.

"Will the gentlemen drink a little sake?" Sato asked politely.

Craig thanked him and said that we would.

"Otaka!" Sato called.

A peculiar, almost white-skinned attendant answered, and a moment later
produced four cups and poured out the rice brandy, taking his own
quietly, apart from us. I watched him drink, curiously. He took the
cup; then, with a long piece of carved wood, he dipped into the sake,
shaking a few drops on the floor to the four quarters. Finally, with a
deft sweep, he lifted his heavy mustache with the piece of wood and
drank off the draft almost without taking breath.

He was a peculiar man of middle height, with a shock of dark, tough,
woolly hair, well formed and not bad-looking, with a robust general
physique, as if his ancestors had been meat eaters. His forehead was
narrow and sloped backward; the cheekbones were prominent; nose hooked,
broad and wide, with strong nostrils; mouth large, with thick lips, and
not very prominent chin. His eyes were perhaps the most noticeable
feature. They were dark gray, almost like those of a European.

As Otaka withdrew with the empty cups, we rose to continue our
inspection of the wonders of the shop. There were ivories of all
descriptions. Here was a two-handled sword, with a very large ivory
handle, a weirdly carved scabbard, and wonderful steel blade. By the
expression of Craig's face, Sato knew that he had made a sale.

Craig had been rummaging among some warlike instruments which Sato,
with the instincts of a true salesman, was now displaying, and had
picked up a bow. It was short, very strong, and made of pine wood. He
held it horizontally and twanged the string. I looked up in time to
catch a pleased expression on the face of Otaka.

"Most people would have held it the other way," commented Sato.

Craig said nothing, but was examining an arrow, almost twenty inches
long and thick, made of cane, with a point of metal very sharp but
badly fastened. He fingered the deep blood groove in the scooplike head
of the arrow and looked at it carefully.

"I'll take that," he said, "only I wish it were one with the regular
reddish-brown lump in it."

"Oh, but, honorable sir," apologized Sato, "the Japanese law prohibits
that, now. There are few of those, and they are very valuable."

"I suppose so," agreed Craig. "This will do, though. You have a
wonderful shop here, Sato. Some time, when I feel richer, I mean to
come in again. No, thank you, you need not send them; I'll carry them."

We bowed ourselves out, promising to come again when Sato received a
new consignment from the Orient which he was expecting.

"That other Jap is a peculiar fellow," I observed, as we walked along
uptown again.

"He isn't a Jap," remarked Craig. "He is an Ainu, one of the aborigines
who have been driven northward into the island of Yezo."

"An Ainu?" I repeated.

"Yes. Generally thought, now, to be a white race and nearer of kin to
Europeans than Asiatics. The Japanese have pushed them northward and
are now trying to civilize them. They are a dirty, hairy race, but when
they are brought under civilizing influences they adapt themselves to
their environment and make very good servants. Still, they are on about
the lowest scale of humanity."

"I thought Otaka was very mild," I commented.

"They are a most inoffensive and peaceable people usually," he
answered, "good-natured and amenable to authority. But they become
dangerous when driven to despair by cruel treatment. The Japanese
government is very considerate of them--but not all Japanese are."



CHAPTER XII

THE ARROW POISON


Far into the night Craig was engaged in some very delicate and minute
microscopic work in the laboratory.

We were about to leave when there was a gentle tap on the door. Kennedy
opened it and admitted a young man, the operative of the detective
agency who had been shadowing Bernardo. His report was very brief, but,
to me at least, significant. Bernardo, on his return to the museum, had
evidently read the letter, which had agitated him very much, for a few
moments later he hurriedly left and went downtown to the Prince Henry
Hotel. The operative had casually edged up to the desk and overheard
whom he asked for. It was Senora Herreria. Once again, later in the
evening, he had asked for her, but she was still out.

It was quite early the next morning, when Kennedy had resumed his
careful microscopic work, that the telephone bell rang, and he answered
it mechanically. But a moment later a look of intense surprise crossed
his face.

"It was from Doctor Leslie," he announced, hanging up the receiver
quickly. "He has a most peculiar case which he wants me to see--a
woman."

Kennedy called a cab, and, at a furious pace, we dashed across the city
and down to the Metropolitan Hospital, where Doctor Leslie was waiting.
He met us eagerly and conducted us to a little room where, lying
motionless on a bed, was a woman.

She was a striking-looking woman, dark of hair and skin, and in life
she must have been sensuously attractive. But now her face was drawn
and contorted--with the same ghastly look that had been on the face of
Northrop.

"She died in a cab," explained Doctor Leslie, "before they could get
her to the hospital. At first they suspected the cab driver. But he
seems to have proved his innocence. He picked her up last night on
Fifth Avenue, reeling--thought she was intoxicated. And, in fact, he
seems to have been right. Our tests have shown a great deal of alcohol
present, but nothing like enough to have had such a serious effect."

"She told nothing of herself?" asked Kennedy.

"No; she was pretty far gone when the cabby answered her signal. All he
could get out of her was a word that sounded like 'Curio-curio.' He
says she seemed to complain of something about her mouth and head. Her
face was drawn and shrunken; her hands were cold and clammy, and then
convulsions came on. He called an ambulance, but she was past saving
when it arrived. The numbness seemed to have extended over all her
body; swallowing was impossible; there was entire loss of her voice as
well as sight, and death took place by syncope."

"Have you any clue to the cause of her death?" asked Craig.

"Well, it might have been some trouble with her heart, I suppose,"
remarked Doctor Leslie tentatively.

"Oh, she looks strong that way. No, hardly anything organic."

"Well, then I thought she looked like a Mexican," went on Doctor
Leslie. "It might be some new tropical disease. I confess I don't know.
The fact is," he added, lowering his voice, "I had my own theory about
it until a few moments ago. That was why I called you."

"What do you mean?" asked Craig, evidently bent on testing his own
theory by the other's ignorance.

Doctor Leslie made no answer immediately, but raised the sheet which
covered her body and disclosed, in the fleshy part of the upper arm, a
curious little red swollen mark with a couple of drops of darkened
blood.

"I thought at first," he added, "that we had at last a genuine
'poisoned needle' case. You see, that looked like it. But I have made
all the tests for curare and strychnin without results."

At the mere suggestion, a procession of hypodermic-needle and
white-slavery stories flashed before me.

"But," objected Kennedy, "clearly this was not a case of kidnaping. It
is a case of murder. Have you tested for the ordinary poisons?"

Doctor Leslie shook his head. "There was no poison," he said,
"absolutely none that any of our tests could discover."

Kennedy bent over and squeezed out a few drops of liquid from the wound
on a microscope slide, and covered them.

"You have not identified her yet," he added, looking up. "I think you
will find, Leslie, that there is a Senora Herreria registered at the
Prince Henry who is missing, and that this woman will agree with the
description of her. Anyhow, I wish you would look it up and let me
know."

Half an hour later, Kennedy was preparing to continue his studies with
the microscope when Doctor Bernardo entered. He seemed most solicitous
to know what progress was being made on the case, and, although Kennedy
did not tell much, still he did not discourage conversation on the
subject.

When we came in the night before, Craig had unwrapped and tossed down
the Japanese sword and the Ainu bow and arrow on a table, and it was
not long before they attracted Bernardo's attention.

"I see you are a collector yourself," he ventured, picking them up.

"Yes," answered Craig, offhand; "I picked them up yesterday at Sato's.
You know the place?"

"Oh, yes, I know Sato," answered the curator, seemingly without the
slightest hesitation. "He has been in Mexico--is quite a student."

"And the other man, Otaka?"

"Other man--Otaka? You mean his wife?"

I saw Kennedy check a motion of surprise and came to the rescue with
the natural question: "His wife--with a beard and mustache?"

It was Bernardo's turn to be surprised. He looked at me a moment, then
saw that I meant it, and suddenly his face lighted up.

"Oh," he exclaimed, "that must have been on account of the immigration
laws or something of the sort. Otaka is his wife. The Ainus are much
sought after by the Japanese as wives. The women, you know, have a
custom of tattooing mustaches on themselves. It is hideous, but they
think it is beautiful."

"I know," I pursued, watching Kennedy's interest in our conversation,
"but this was not tattooed."

"Well, then, it must have been false," insisted Bernardo.

The curator chatted a few moments, during which I expected Kennedy to
lead the conversation around to Senora Herreria. But he did not,
evidently fearing to show his hand.

"What did you make of it?" I asked, when he had gone. "Is he trying to
hide something?"

"I think he has simplified the case," remarked Craig, leaning back, his
hands behind his head, gazing up at the ceiling. "Hello, here's Leslie!
What did you find, Doctor?" The coroner had entered with a look of awe
on his face, as if Kennedy had directed him by some sort of necromancy.

"It was Senora Herreria!" he exclaimed. "She has been missing from the
hotel ever since late yesterday afternoon. What do you think of it?"

"I think," replied Kennedy, speaking slowly and deliberately, "that it
is very much like the Northrop case. You haven't taken that up yet?"

"Only superficially. What do you make of it?" asked the coroner.

"I had an idea that it might be aconitin poisoning," he said.

Leslie glanced at him keenly for a moment. "Then you'll never prove
anything in the laboratory," he said.

"There are more ways of catching a criminal, Leslie," put in Craig,
"than are set down in the medico-legal text-books. I shall depend on
you and Jameson to gather together a rather cosmopolitan crowd here
to-night."

He said it with a quiet confidence which I could not gainsay, although
I did not understand. However, mostly with the official aid of Doctor
Leslie, I followed out his instructions, and it was indeed a strange
party that assembled that night. There were Doctor Bernardo; Sato, the
curio dealer; Otaka, the Ainu, and ourselves. Mrs. Northrop, of course,
could not come.

"Mexico," began Craig, after he had said a few words explaining why he
had brought us together, "is full of historical treasure. To all
intents and purposes, the government says, 'Come and dig.' But when
there are finds, then the government swoops down on them for its own
national museum. The finder scarcely gets a chance to export them.
However, now seemed to be the time to Professor Northrop to smuggle his
finds out of the country.

"But evidently it could not be done without exciting all kinds of
rumors and suspicions. Stories seem to have spread far and fast about
what he had discovered. He realized the unsettled condition of the
country--perhaps wanted to confirm his reading of a certain inscription
by consultation with one scholar whom he thought he could trust. At any
rate, he came home."

Kennedy paused, making use of the silence for emphasis. "You have all
read of the wealth that Cortez found in Mexico. Where are the gold and
silver of the conquistadores? Gone to the melting pot, centuries ago.
But is there none left? The Indians believe so. There are persons who
would stop at nothing--even at murder of American professors, murder of
their own comrades, to get at the secret."

He laid his hand almost lovingly on his powerful little microscope as
he resumed on another line of evidence.

"And while we are on the subject of murders, two very similar deaths
have occurred," he went on. "It is of no use to try to gloss them over.
Frankly, I suspected that they might have been caused by aconite
poisoning. But, in the case of such poisoning, not only is the lethal
dose very small but our chemical methods of detection are nil. The dose
of the active principle, aconitin nitrate, is about one six-hundredth
of a grain. There are no color tests, no reactions, as in the case of
the other organic poisons."

I wondered what he was driving at. Was there, indeed, no test? Had the
murderer used the safest of poisons--one that left no clue? I looked
covertly at Sato's face. It was impassive. Doctor Bernardo was visibly
uneasy as Kennedy proceeded. Cool enough up to the time of the mention
of the treasure, I fancied, now, that he was growing more and more
nervous.

Craig laid down on the table the reed stick with the little darkened
cylinder on the end.

"That," he said, "is a little article which I picked up beneath
Northrop's window yesterday. It is a piece of anno-noki, or bushi." I
fancied I saw just a glint of satisfaction in Otaka's eyes.

"Like many barbarians," continued Craig, "the Ainus from time
immemorial have prepared virulent poisons with which they charged their
weapons of the chase and warfare. The formulas for the preparations, as
in the case of other arrow poisons of other tribes, are known only to
certain members, and the secret is passed down from generation to
generation as an heirloom, as it were. But in this case it is no longer
a secret. It has now been proved that the active principle of this
poison is aconite."

"If that is the case," broke in Doctor Leslie, "it is hopeless to
connect anyone directly in that way with these murders. There is no
test for aconitin."

I thought Sato's face was more composed and impassive than ever. Doctor
Bernardo, however, was plainly excited.

"What--no test--NONE?" asked Kennedy, leaning forward eagerly. Then, as
if he could restrain the answer to his own question no longer, he shot
out: "How about the new starch test just discovered by Professor
Reichert, of the University of Pennsylvania? Doubtless you never
dreamed that starch may be a means of detecting the nature of a poison
in obscure cases in criminology, especially in cases where the quantity
of poison necessary to cause death is so minute that no trace of it can
be found in the blood.

"The starch method is a new and extremely inviting subject to me. The
peculiarities of the starch of any plant are quite as distinctive of
the plant as are those of the hemoglobin crystals in the blood of an
animal. I have analyzed the evidence of my microscope in this case
thoroughly. When the arrow poison is introduced subcutaneously--say, by
a person shooting a poisoned dart, which he afterward removes in order
to destroy the evidence--the lethal constituents are rapidly absorbed.

"But the starch remains in the wound. It can be recovered and studied
microscopically and can be definitely recognized. Doctor Reichert has
published a study of twelve hundred such starches from all sorts of
plants. In this case, it not only proves to be aconitin but the starch
granules themselves can be recognized. They came from this piece of
arrow poison."

Every eye was fixed on him now.

"Besides," he rapped out, "in the soft soil beneath the window of
Professor Northrop's room, I found footprints. I have only to compare
the impressions I took there and those of the people in this room, to
prove that, while the real murderer stood guard below the window, he
sent some one more nimble up the rain pipe to shoot the poisoned dart
at Professor Northrop, and, later, to let down a rope by which he, the
instigator, could gain the room, remove the dart, and obtain the key to
the treasure he sought."

Kennedy was looking straight at Professor Bernardo.

"A friend of mine in Mexico has written me about an inscription," he
burst out. "I received the letter only to-day. As nearly as I can
gather, there was an impression that some of Northrop's stuff would be
valuable in proving the alleged kinship between Mexico and Japan,
perhaps to arouse hatred of the United States."

"Yes--that is all very well," insisted Kennedy. "But how about the
treasure?"

"Treasure?" repeated Bernardo, looking from one of us to another.

"Yes," pursued Craig relentlessly, "the treasure. You are an expert in
reading the hieroglyphics. By your own statement, you and Northrop had
been going over the stuff he had sent up. You know it."

Bernardo gave a quick glance from Kennedy to me. Evidently he saw that
the secret was out.

"Yes," he said huskily, in a low tone, "Northrop and I were to follow
the directions after we had plotted them out and were to share it
together on the next expedition, which I could direct as a Mexican
without so much suspicion. I should still have shared it with his widow
if this unfortunate affair had not exposed the secret."

Bernardo had risen earnestly.

"Kennedy," he cried, "before God, if you will get back that stone and
keep the secret from going further than this room, I will prove what I
have said by dividing the Mixtec treasure with Mrs. Northrop and making
her one of the richest widows in the country!"

"That is what I wanted to be sure of," nodded Craig. "Bernardo, Senora
Herreria, of whom your friend wrote to you from Mexico, has been
murdered in the same way that Professor Northrop was. Otaka was sent by
her husband to murder Northrop, in order that they might obtain the
so-called 'Pillar of Death' and the key to the treasure. Then, when the
senora was no doubt under the influence of sake in the pretty little
Oriental bower at the curio shop, a quick jab, and Otaka had removed
one who shared the secret with them."

He had turned and faced the pair.

"Sato," he added, "you played on the patriotism of the senora until you
wormed from her the treasure secret. Evidently rumors of it had spread
from Mexican Indians to Japanese visitors. And then, Otaka, all
jealousy over one whom she, no doubt, justly considered a rival,
completed your work by sending her forth to die, unknown, on the
street. Walter, ring up First Deputy O'Connor. The stone is hidden
somewhere in the curio shop. We can find it without Sato's help. The
quicker such a criminal is lodged safely in jail, the better for
humanity."

Sato was on his feet, advancing cautiously toward Craig. I knew the
dangers, now, of anno-noki, as well as the wonders of jujutsu, and,
with a leap, I bounded past Bernardo and between Sato and Kennedy.

How it happened, I don't know, but, an instant later, I was sprawling.

Before I could recover myself, before even Craig had a chance to pull
the hair-trigger of his automatic, Sato had seized the Ainu arrow
poison from the table, had bitten the little cylinder in half, and had
crammed the other half into the mouth of Otaka.



CHAPTER XIII

THE RADIUM ROBBER


Kennedy simply reached for the telephone and called an ambulance. But
it was purely perfunctory. Dr. Leslie himself was the only official who
could handle Sato's case now.

We had planned a little vacation for ourselves, but the planning came
to naught. The next night we spent on a sleeper. That in itself is work
to me.

It all came about through a hurried message from Murray Denison,
president of the Federal Radium Corporation. Nothing would do but that
he should take both Kennedy and myself with him post-haste to
Pittsburgh at the first news of what had immediately been called "the
great radium robbery."

Of course the newspapers were full of it. The very novelty of an
ultra-modern cracksman going off with something worth upward of a
couple of hundred thousand dollars--and all contained in a few platinum
tubes which could be tucked away in a vest pocket--had something about
it powerfully appealing to the imagination.

"Most ingenious, but, you see, the trouble with that safe is that it
was built to keep radium IN--not cracksmen OUT," remarked Kennedy, when
Denison had rushed us from the train to take a look at the little safe
in the works of the Corporation.

"Breaking into such a safe as this," added Kennedy, after a cursory
examination, "is simple enough, after all."

It was, however, a remarkably ingenious contrivance, about three feet
in height and of a weight of perhaps a ton and a half, and all to house
something weighing only a few grains.

"But," Denison hastened to explain, "we had to protect the radium not
only against burglars, but, so to speak, against itself. Radium
emanations pass through steel and experiments have shown that the best
metal to contain them is lead. So, the difficulty was solved by making
a steel outer case enclosing an inside leaden shell three inches thick."

Kennedy had been toying thoughtfully with the door.

"Then the door, too, had to be contrived so as to prevent any escape of
the emanations through joints. It is lathe turned and circular, a 'dead
fit.' By means of a special contrivance any slight looseness caused by
wear and tear of closing can be adjusted. And another feature. That is
the appliance for preventing the loss of emanation when the door is
opened. Two valves have been inserted into the door and before it is
opened tubes with mercury are passed through which collect and store
the emanation."

"All very nice for the radium," remarked Craig cheerfully. "But the
fellow had only to use an electric drill and the gram or more of radium
was his."

"I know that--now," ruefully persisted Denison. "But the safe was
designed for us specially. The fellow got into it and got away, as far
as I can see, without leaving a clue."

"Except one, of course," interrupted Kennedy quickly.

Denison looked at him a moment keenly, then nodded and said, "Yes--you
are right. You mean one which he must bear on himself?"

"Exactly. You can't carry a gram or more of radium bromide long with
impunity. The man to look for is one who in a few days will have
somewhere on his body a radium burn which will take months to heal. The
very thing he stole is a veritable Frankenstein's monster bent on the
destruction of the thief himself!"

Kennedy had meanwhile picked up one of the Corporation's circulars
lying on a desk. He ran his eye down the list of names.

"So, Hartley Haughton, the broker, is one of your stockholders," mused
Kennedy.

"Not only one but THE one," replied Denison with obvious pride.

Haughton was a young man who had come recently into his fortune, and,
while no one believed it to be large, he had cut quite a figure in Wall
Street.

"You know, I suppose," added Denison, "that he is engaged to Felicie
Woods, the daughter of Mrs. Courtney Woods?"

Kennedy did not, but said nothing.

"A most delightful little girl," continued Denison thoughtfully. "I
have known Mrs. Woods for some time. She wanted to invest, but I told
her frankly that this is, after all, a speculation. We may not be able
to swing so big a proposition, but, if not, no one can say we have
taken a dollar of money from widows and orphans."

"I should like to see the works," nodded Kennedy approvingly.

"By all means."

The plant was a row of long low buildings of brick on the outskirts of
the city, once devoted to the making of vanadium steel. The ore, as
Denison explained, was brought to Pittsburgh because he had found here
already a factory which could readily be turned into a plant for the
extraction of radium. Huge baths and vats and crucibles for the various
acids and alkalis and other processes used in treating the ore stood at
various points.

"This must be like extracting gold from sea water," remarked Kennedy
jocosely, impressed by the size of the plant as compared to the product.

"Except that after we get through we have something infinitely more
precious than gold," replied Denison, "something which warrants the
trouble and outlay. Yes, the fact is that the percentage of radium in
all such ores is even less than of gold in sea water."

"Everything seems to be most carefully guarded," remarked Kennedy as we
concluded our tour of the well-appointed works.

He had gone over everything in silence, and now at last we had returned
to the safe.

"Yes," he repeated slowly, as if confirming his original impression,
"such an amount of radium as was stolen wouldn't occasion immediate
discomfort to the thief, I suppose, but later no infernal machine could
be more dangerous to him."

I pictured to myself the series of fearful works of mischief and terror
that might follow, a curse on the thief worse than that of the weirdest
curses of the Orient, the danger to the innocent, and the fact that in
the hands of a criminal it was an instrument for committing crimes that
might defy detection.

"There is nothing more to do here now," he concluded. "I can see
nothing for the present except to go back to New York. The telltale
burn may not be the only clue, but if the thief is going to profit by
his spoils we shall hear about it best in New York or by cable from
London, Paris, or some other European city."

Our hurried departure from New York had not given us a chance to visit
the offices of the Radium Corporation for the distribution of the salts
themselves. They were in a little old office building on William
Street, near the drug district and yet scarcely a moment's walk from
the financial district.

"Our head bookkeeper, Miss Wallace, is ill," remarked Denison when we
arrived at the office, "but if there is anything I can do to help you,
I shall be glad to do it. We depend on Miss Wallace a great deal.
Haughton says she is the brains of the office."

Kennedy looked about the well-appointed suite curiously.

"Is this another of those radium safes?" he asked, approaching one
similar in appearance to that which had been broken open already.

"Yes, only a little larger."

"How much is in it?"

"Most of our supply. I should say about two and a half grams. Miss
Wallace has the record."

"It is of the same construction, I presume," pursued Kennedy. "I wonder
whether the lead lining fits closely to the steel?"

"I think not," considered Denison. "As I remember there was a sort of
insulating air cushion or something of the sort."

Denison was quite eager to show us about. In fact ever since he had
hustled us out to view the scene of the robbery, his high nervous
tension had given us scarcely a moment's rest. For hours he had talked
radium, until I felt that he, like his metal, must have an
inexhaustible emanation of words. He was one of those nervous, active
little men, a born salesman, whether of ribbons or radium.

"We have just gone into furnishing radium water," he went on, bustling
about and patting a little glass tank.

I looked closely and could see that the water glowed in the dark with a
peculiar phosphorescence.

"The apparatus for the treatment," he continued, "consists of two glass
and porcelain receptacles. Inside the larger receptacle is placed the
smaller, which contains a tiny quantity of radium. Into the larger
receptacle is poured about a gallon of filtered water. The emanation
from that little speck of radium is powerful enough to penetrate its
porcelain holder and charge the water with its curative properties.
From a tap at the bottom of the tank the patient draws the number of
glasses of water a day prescribed. For such purposes the emanation
within a day or two of being collected is as good as radium itself.
Why, this water is five thousand times as radioactive as the most
radioactive natural spring water."

"You must have control of a comparatively large amount of the metal,"
suggested Kennedy.

"We are, I believe, the largest holders of radium in the world," he
answered. "I have estimated that all told there are not much more than
ten grams, of which Madame Curie has perhaps three, while Sir Ernest
Cassel of London is the holder of perhaps as much. We have nearly four
grams, leaving about six or seven for the rest of the world."

Kennedy nodded and continued to look about.

"The Radium Corporation," went on Denison, "has several large deposits
of radioactive ore in Utah in what is known as the Poor Little Rich
Valley, a valley so named because from being about the barrenest and
most unproductive mineral or agricultural hole in the hills, the sudden
discovery of the radioactive deposits has made it almost priceless."

He had entered a private office and was looking over some mail that had
been left on his desk during his absence.

"Look at this," he called, picking up a clipping from a newspaper which
had been laid there for his attention. "You see, we have them aroused."

We read the clipping together hastily:

PLAN TO CORNER WORLD'S RADIUM

LONDON.--Plans are being matured to form a large corporation for the
monopoly of the existing and future supply of radium throughout the
world. The company is to be called Universal Radium, Limited, and the
capital of ten million dollars will be offered for public subscription
at par simultaneously in London, Paris and New York.

The company's business will be to acquire mines and deposits of
radioactive substances as well as the control of patents and processes
connected with the production of radium. The outspoken purpose of the
new company is to obtain a world-wide monopoly and maintain the price.

 "Ah--a competitor," commented Kennedy, handing back the clipping.

"Yes. You know radium salts used always to come from Europe. Now we are
getting ready to do some exporting ourselves. Say," he added excitedly,
"there's an idea, possibly, in that."

"How?" queried Craig.

"Why, since we should be the principal competitors to the foreign
mines, couldn't this robbery have been due to the machinations of these
schemers? To my mind, the United States, because of its supply of
radium-bearing ores, will have to be reckoned with first in cornering
the market. This is the point, Kennedy. Would those people who seem to
be trying to extend their new company all over the world stop at
anything in order to cripple us at the start?"

How much longer Denison would have rattled on in his effort to explain
the robbery, I do not know. The telephone rang and a reporter from the
Record, who had just read my own story in the Star, asked for an
interview. I knew that it would be only a question of minutes now
before the other men were wearing a path out on the stairs, and we
managed to get away before the onrush began.

"Walter," said Kennedy, as soon as we had reached the street. "I want
to get in touch with Halsey Haughton. How can it be done?"

I could think of nothing better at that moment than to inquire at the
Star's Wall Street office, which happened to be around the corner. I
knew the men down there intimately, and a few minutes later we were
whisked up in the elevator to the office.

They were as glad to see me as I was to see them, for the story of the
robbery had interested the financial district perhaps more than any
other.

"Where can I find Halsey Haughton at this hour?" I asked.

"Say," exclaimed one of the men, "what's the matter? There have been
all kinds of rumors in the Street about him to-day. Did you know he was
ill?"

"No," I answered. "Where is he?"

"Out at the home of his fiancee, who is the daughter of Mrs. Courtney
Woods, at Glenclair."

"What's the matter?" I persisted.

"That's just it. No one seems to know. They say--well--they say he has
a cancer."

Halsey Haughton suffering from cancer? It was such an uncommon thing to
hear of a young man that I looked up quickly in surprise. Then all at
once it flashed over me that Denison and Kennedy had discussed the
matter of burns from the stolen radium. Might not this be, instead of
cancer, a radium burn?

Kennedy, who had been standing a little apart from me while I was
talking with the boys, signaled to me with a quick glance not to say
too much, and a few minutes later we were on the street again.

I knew without being told that he was bound by the next train to the
pretty little New Jersey suburb of Glenclair.

It was late when we arrived, yet Kennedy had no hesitation in calling
at the quaint home of Mrs. Courtney Woods on Woodridge Avenue.

Mrs. Woods, a well-set-up woman of middle age, who had retained her
youth and good looks in a remarkable manner, met us in the foyer.
Briefly, Kennedy explained that we had just come in from Pittsburgh
with Mr. Denison and that it was very important that we should see
Haughton at once.

We had hardly told her the object of our visit when a young woman of
perhaps twenty-two or three, a very pretty girl, with all the good
looks of her mother and a freshness which only youth can possess,
tiptoed quietly downstairs. Her face told plainly that she was deeply
worried over the illness of her fiance.

"Who is it, mother?" she whispered from the turn in the stairs. "Some
gentlemen from the company? Hartley's door was open when the bell rang,
and he thought he heard something said about the Pittsburgh affair."

Though she had whispered, it had not been for the purpose of concealing
anything from us, but rather that the keen ears of her patient might
not catch the words. She cast an inquiring glance at us.

"Yes," responded Kennedy in answer to her look, modulating his tone.
"We have just left Mr. Denison at the office. Might we see Mr. Haughton
for a moment? I am sure that nothing we can say or do will be as bad
for him as our going away, now that he knows that we are here."

The two women appeared to consult for a moment.

"Felicie," called a rather nervous voice from the second floor, "is it
some one from the company?"

"Just a moment, Hartley," she answered, then, lower to her mother,
added, "I don't think it can do any harm, do you, mother?"

"You remember the doctor's orders, my dear."

Again the voice called her.

"Hang the doctor's orders," the girl exclaimed, with an air of almost
masculinity. "It can't be half so bad as to have him worry. Will you
promise not to stay long? We expect Dr. Bryant in a few moments,
anyway."



CHAPTER XIV

THE SPINTHARISCOPE


We followed her upstairs and into Haughton's room, where he was lying
in bed, propped up by pillows. Haughton certainly was ill. There was no
mistake about that. He was a tall, gaunt man with an air about him that
showed that he found illness very irksome. Around his neck was a
bandage, and some adhesive tape at the back showed that a plaster of
some sort had been placed there.

As we entered his eyes traveled restlessly from the face of the girl to
our own in an inquiring manner. He stretched out a nervous hand to us,
while Kennedy in a few short sentences explained how we had become
associated with the case and what we had seen already.

"And there is not a clue?" he repeated as Craig finished.

"Nothing tangible yet," reiterated Kennedy. "I suppose you have heard
of this rumor from London of a trust that is going into the radium
field internationally?"

"Yes," he answered, "that is the thing you read to me in the morning
papers, you remember, Felicie. Denison and I have heard such rumors
before. If it is a fight, then we shall give them a fight. They can't
hold us up, if Denison is right in thinking that they are at the bottom
of this--this robbery."

"Then you think he may be right?" shot out Kennedy quickly.

Haughton glanced nervously from Kennedy to me.

"Really," he answered, "you see how impossible it is for me to have an
opinion? You and Denison have been over the ground. You know much more
about it than I do. I am afraid I shall have to defer to you."

Again we heard the bell downstairs, and a moment later a cheery voice,
as Mrs. Woods met some one down in the foyer, asked, "How is the
patient to-night?"

We could not catch the reply.

"Dr. Bryant, my physician," put in Haughton. "Don't go. I will assume
the responsibility for your being here. Hello, Doctor. Why, I'm much
the same to-night, thank you. At least no worse since I took your
advice and went to bed."

Dr. Bryant was a bluff, hearty man, with the personal magnetism which
goes with the making of a successful physician. He had mounted the
stairs quietly but rapidly, evidently prepared to see us.

"Would you mind waiting in this little dressing room?" asked the
doctor, motioning to another, smaller room adjoining.

He had taken from his pocket a little instrument with a dial face like
a watch, which he attached to Haughton's wrist. "A pocket instrument to
measure blood pressure," whispered Craig, as we entered the little room.

While the others were gathered about Haughton, we stood in the next
room, out of earshot. Kennedy had leaned his elbow on a chiffonier. As
he looked about the little room, more from force of habit than because
he thought he might discover anything, Kennedy's eye rested on a glass
tray on the top in which lay some pins, a collar button or two, which
Haughton had apparently just taken off, and several other little
unimportant articles.

Kennedy bent over to look at the glass tray more closely, a puzzled
look crossed his face, and with a glance at the other room he gathered
up the tray and its contents.

"Keep up a good courage," said Dr. Bryant. "You'll come out all right,
Haughton." Then as he left the bedroom he added to us, "Gentlemen, I
hope you will pardon me, but if you could postpone the remainder of
your visit until a later day, I am sure you will find it more
satisfactory."

There was an air of finality about the doctor, though nothing
unpleasant in it. We followed him down the stairs, and as we did so,
Felicie, who had been waiting in a reception room, appeared before the
portieres, her earnest eyes fixed on his kindly face.

"Dr. Bryant," she appealed, "is he--is he, really--so badly?"

The Doctor, who had apparently known her all her life, reached down and
took one of her hands, patting it with his own in a fatherly way.
"Don't worry, little girl," he encouraged. "We are going to come out
all right--all right."

She turned from him to us and, with a bright forced smile which showed
the stuff she was made of, bade us good night.

Outside, the Doctor, apparently regretting that he had virtually forced
us out, paused before his car. "Are you going down toward the station?
Yes? I am going that far. I should be glad to drive you there."

Kennedy climbed into the front seat, leaving me in the rear where the
wind wafted me their brief conversation as we sped down Woodbridge
Avenue.

"What seems to be the trouble?" asked Craig.

"Very high blood pressure, for one thing," replied the Doctor frankly.

"For which the latest thing is the radium water cure, I suppose?"
ventured Kennedy.

"Well, radioactive water is one cure for hardening of the arteries. But
I didn't say he had hardening of the arteries. Still, he is taking the
water, with good results. You are from the company?"

Kennedy nodded.

"It was the radium water that first interested him in it. Why, we found
a pressure of 230 pounds, which is frightful, and we have brought it
down to 150, not far from normal."

"Still that could have nothing to do with the sore on his neck,"
hazarded Kennedy.

The Doctor looked at him quickly, then ahead at the path of light which
his motor shed on the road.

He said nothing, but I fancied that even he felt there was something
strange in his silence over the new complication. He did not give
Kennedy a chance to ask whether there were any other such sores.

"At any rate," he said, as he throttled down his engine with a flourish
before the pretty little Glenclair station, "that girl needn't worry."

There was evidently no use in trying to extract anything further from
him. He had said all that medical ethics or detective skill could get
from him. We thanked him and turned to the ticket window to see how
long we should have to wait.

"Either that doctor doesn't know what he is talking about or he is
concealing something," remarked Craig, as we paced up and down the
platform. "I am inclined to read the enigma in the latter way."

Nothing more passed between us during the journey back, and we hurried
directly to the laboratory, late as it was. Kennedy had evidently been
revolving something over and over in his mind, for the moment he had
switched on the light, he unlocked one of his air-and dust-proof
cabinets and took from it an instrument which he placed on a table
before him.

It was a peculiar-looking instrument, like a round glass electric
battery with a cylinder atop, smaller and sticking up like a safety
valve. On that were an arm, a dial, and a lens fixed in such a way as
to read the dial. I could not see what else the rather complicated
little apparatus consisted of, but inside, when Kennedy brought near it
the pole of a static electric machine two delicate thin leaves of gold
seemed to fly wide apart when it was charged.

Kennedy had brought the glass tray near the thing. Instantly the leaves
collapsed and he made a reading through the lens.

"What is it?" I asked.

"A radioscope," he replied, still observing the scale. "Really a very
sensitive gold leaf electroscope, devised by one of the students of
Madame Curie. This method of detection is far more sensitive even than
the spectroscope."

"What does it mean when the leaves collapse?" I asked.

"Radium has been near that tray," he answered. "It is radioactive. I
suspected it first when I saw that violet color. That is what radium
does to that kind of glass. You see, if radium exists in a gram of
inactive matter only to the extent of one in ten-thousand million parts
its presence can be readily detected by this radioscope, and everything
that has been rendered radioactive is the same. Ordinarily the air
between the gold leaves is insulating. Bringing something radioactive
near them renders the air a good conductor and the leaves fall under
the radiation."

"Wonderful!" I exclaimed, marveling at the delicacy of it.

"Take radium water," he went on, "sufficiently impregnated with radium
emanations to be luminous in the dark, like that water of Denison's. It
would do the same. In fact all mineral waters and the so-called
curarive muds like fango are slightly radioactive. There seems to be a
little radium everywhere on earth that experiments have been made, even
in the interiors of buildings. It is ubiquitous. We are surrounded and
permeated by radiations--that soil out there on the campus, the air of
this room, all. But," he added contemplatively, "there is something
different about that tray. A lot of radium has been near that, and
recently."

"How about that bandage about Haughton's neck?" I asked suddenly. "Do
you think radium could have had anything to do with that?" "Well, as to
burns, there is no particular immediate effect usually, and sometimes
even up to two weeks or more, unless the exposure has been long and to
a considerable quantity. Of course radium keeps itself three or four
degrees warmer than other things about it constantly. But that isn't
what does the harm. It is continually emitting little corpuscles, which
I'll explain some other time, traveling all the way from twenty to one
hundred and thirty thousand miles a second, and these corpuscles
blister and corrode the flesh like quick-moving missiles bombarding it.
The gravity of such lesions increases with the purity of the radium.
For instance I have known an exposure of half an hour to a
comparatively small quantity through a tube, a box and the clothes to
produce a blister fifteen days later. Curie said he wouldn't trust
himself in a room with a kilogram of it. It would destroy his eyesight,
burn off his skin and kill him eventually. Why, even after a slight
exposure your clothes are radioactive--the electroscope will show that."

He was still fumbling with the glass plate and the various articles on
it.

"There's something very peculiar about all this," he muttered, almost
to himself.

Tired by the quick succession of events of the past two days, I left
Kennedy still experimenting in his laboratory and retired, still
wondering when the real clue was to develop. Who could it have been who
bore the tell-tale burn? Was the mark hidden by the bandage about
Haughton's neck the brand of the stolen tubes? Or were there other
marks on his body which we could not see?

No answer came to me, and I fell asleep and woke up without a radiation
of light on the subject. Kennedy spent the greater part of the day
still at work at his laboratory, performing some very delicate
experiments. Finding nothing to do there, I went down to the Star
office and spent my time reading the reports that came in from the
small army of reporters who had been assigned to run down clues in the
case which was the sensation of the moment. I have always felt my own
lips sealed in such cases, until the time came that the story was
complete and Kennedy released me from any further need of silence. The
weird and impossible stories which came in not only to the Star but to
the other papers surely did make passable copy in this instance, but
with my knowledge of the case I could see that not one of them brought
us a step nearer the truth.

One thing which uniformly puzzled the newspapers was the illness of
Haughton and his enforced idleness at a time which was of so much
importance to the company which he had promoted and indeed very largely
financed. Then, of course, there was the romantic side of his
engagement to Felicie Woods.

Just what connection Felicie Woods had with the radium robbery if any,
I was myself unable quite to fathom. Still, that made no difference to
the papers. She was pretty and therefore they published her picture,
three columns deep, with Haughton and Denison, who were intimately
concerned with the real loss in little ovals perhaps an inch across and
two inches in the opposite dimension.

The late afternoon news editions had gone to press, and I had given up
in despair, determined to go up to the laboratory and sit around idly
watching Kennedy with his mystifying experiments, in preference to
waiting for him to summon me.

I had scarcely arrived and settled myself to an impatient watch, when
an automobile drove up furiously, and Denison himself, very excited,
jumped out and dashed into the laboratory.

"What's the matter?" asked Kennedy, looking up from a test tube which
he had been examining, with an air for all the world expressive of "Why
so hot, little man?"

"I've had a threat," ejaculated Denison.

He laid on one of the laboratory tables a letter, without heading and
without signature, written in a disguised hand, with an evident attempt
to simulate the cramped script of a foreign penmanship.

"I know who did the Pittsburgh job. The same party is out to ruin
Federal Radium. Remember Pittsburgh and be prepared!

"A STOCKHOLDER."

"Well?" demanded Kennedy, looking up.

"That can have only one meaning," asserted Denison.

"What is that?" inquired Kennedy coolly, as if to confirm his own
interpretation.

"Why, another robbery--here in New York, of course."

"But who would do it?" I asked.

"Who?" repeated Denison. "Some one representing that European combine,
of course. That is only part of the Trust method--ruin of competitors
whom they cannot absorb."

"Then you have refused to go into the combine? You know who is backing
it?"

"No--no," admitted Denison reluctantly. "We have only signified our
intent to go it alone, as often as anyone either with or without
authority has offered to buy us out. No, I do not even know who the
people are. They never act in the open. The only hints I have ever
received were through perfectly reputable brokers acting for others."

"Does Haughton know of this note?" asked Kennedy.

"Yes. As soon as I received it, I called him up."

"What did he say?"

"He said to disregard it. But--you know what condition he is in. I
don't know what to do, whether to surround the office by a squad of
detectives or remove the radium to a regular safety deposit vault, even
at the loss of the emanation. Haughton has left it to me."

Suddenly the thought flashed across my mind that perhaps Haughton could
act in this uninterested fashion because he had no fear of ruin either
way. Might he not be playing a game with the combination in which he
had protected himself so that he would win, no matter what happened?

"What shall I do?" asked Denison. "It is getting late."

"Neither," decided Kennedy.

Denison shook his head. "No," he said, "I shall have some one watch
there, anyhow."



CHAPTER XV

THE ASPHYXIATING SAFE


Denison had scarcely gone to arrange for some one to watch the office
that night, when Kennedy, having gathered up his radioscope and packed
into a parcel a few other things from various cabinets, announced:
"Walter, I must see that Miss Wallace, right away. Denison has already
given me her address. Call a cab while I finish clearing up here. I
don't like the looks of this thing, even if Haughton does neglect it."

We found Miss Wallace at a modest boarding-house in an old but still
respectable part of the city. She was a very pretty girl, of the
slender type, rather a business woman than one given much to amusement.
She had been ill and was still ill. That was evident from the
solicitous way in which the motherly landlady scrutinized two strange
callers.

Kennedy presented a card from Denison, and she came down to the parlor
to see us.

"Miss Wallace," began Kennedy, "I know it is almost cruel to trouble
you when you are not feeling like office work, but since the robbery of
the safe at Pittsburgh, there have been threats of a robbery of the New
York office."

She started involuntarily, and it was evident, I thought, that she was
in a very high-strung state.

"Oh," she cried, "why, the loss means ruin to Mr. Denison!"

There were genuine tears in her eyes as she said it.

"I thought you would be willing to aid us," pursued Kennedy
sympathetically. "Now, for one thing, I want to be perfectly sure just
how much radium the Corporation owns, or rather owned before the first
robbery."

"The books will show it," she said simply.

"They will?" commented Kennedy. "Then if you will explain to me briefly
just the system you used in keeping account of it, perhaps I need not
trouble you any more."

"I'll go down there with you," she answered bravely. "I'm better
to-day, anyhow, I think."

She had risen, but it was evident that she was not as strong as she
wanted us to think.

"The least I can do is to make it as easy as possible by going in a
car," remarked Kennedy, following her into the hall where there was a
telephone.

The hallway was perfectly dark, yet as she preceded us I could see that
the diamond pin which held her collar in the back sparkled as if a
lighted candle had been brought near it. I had noticed in the parlor
that she wore a handsome tortoiseshell comb set with what I thought
were other brilliants, but when I looked I saw now that there was not
the same sparkle to the comb which held her dark hair in a soft mass. I
noticed these little things at the time, not because I thought they had
any importance, but merely by chance, wondering at the sparkle of the
one diamond which had caught my eye.

"What do you make of her?" I asked as Kennedy finished telephoning.

"A very charming and capable girl," he answered noncommittally.

"Did you notice how that diamond in her neck sparkled?" I asked quickly.

He nodded. Evidently it had attracted his attention, too.

"What makes it?" I pursued.

"Well, you know radium rays will make a diamond fluoresce in the dark."

"Yes," I objected, "but how about those in the comb?"

"Paste, probably," he answered tersely, as we heard her foot on the
landing. "The rays won't affect paste."

It was indeed a shame to take advantage of Miss Wallace's loyalty to
Denison, but she was so game about it that I knew only the utmost
necessity on Kennedy's part would have prompted him to do it. She had a
key to the office so that it was not necessary to wait for Denison, if
indeed we could have found him.

Together she and Kennedy went over the records. It seemed that there
were in the safe twenty-five platinum tubes of one hundred milligrams
each, and that there had been twelve of the same amount at Pittsburgh.
Little as it seemed in weight it represented a fabulous fortune.

"You have not the combination?" inquired Kennedy.

"No. Only Mr. Denison has that. What are you going to do to protect the
safe to-night?" she asked.

"Nothing especially," evaded Kennedy.

"Nothing?" she repeated in amazement.

"I have another plan," he said, watching her intently. "Miss Wallace,
it was too much to ask you to come down here. You are ill."

She was indeed quite pale, as if the excitement had been an
overexertion.

"No, indeed," she persisted. Then, feeling her own weakness, she moved
toward the door of Denison's office where there was a leather couch.
"Let me rest here a moment. I do feel queer. I--"

She would have fallen if he had not sprung forward and caught her as
she sank to the floor, overcome by the exertion.

Together we carried her in to the couch, and as we did so the comb from
her hair clattered to the floor.

Craig threw open the window, and bathed her face with water until there
was a faint flutter of the eyelids.

"Walter," he said, as she began to revive, "I leave her to you. Keep
her quiet for a few moments. She has unintentionally given me just the
opportunity I want."

While she was yet hovering between consciousness and unconsciousness on
the couch, he had unwrapped the package which he had brought with him.
For a moment he held the comb which she had dropped near the
radioscope. With a low exclamation of surprise he shoved it into his
pocket.

Then from the package he drew a heavy piece of apparatus which looked
as if it might be the motor part of an electric fan, only in place of
the fan he fitted a long, slim, vicious-looking steel bit. A flexible
wire attached the thing to the electric light circuit and I knew that
it was an electric drill. With his coat off he tugged at the little
radium safe until he had moved it out, then dropped on his knees behind
it and switched the current on in the electric drill.

It was a tedious process to drill through the steel of the outer casing
of the safe and it was getting late. I shut the door to the office so
that Miss Wallace could not see.

At last by the cessation of the low hum of the boring, I knew that he
had struck the inner lead lining. Quietly I opened the door and stepped
out. He was injecting something from an hermetically sealed lead tube
into the opening he had made and allowing it to run between the two
linings of lead and steel. Then using the tube itself he sealed the
opening he had made and dabbed a little black over it.

Quickly he shoved the safe back, then around it concealed several small
coils with wires also concealed and leading out through a window to a
court.

"We'll catch the fellow this time," he remarked as he worked. "If you
ever have any idea, Walter, of going into the burglary business, it
would be well to ascertain if the safes have any of these little
selenium cells as suggested by my friend, Mr. Hammer, the inventor. For
by them an alarm can be given miles away the moment an intruder's
bull's-eye falls on a hidden cell sensitive to light."

While I was delegated to take Miss Wallace home, Kennedy made
arrangements with a small shopkeeper on the ground floor of a building
that backed up on the court for the use of his back room that night,
and had already set up a bell actuated by a system of relays which the
weak current from the selenium cells could operate.

It was not until nearly midnight that he was ready to leave the
laboratory again, where he had been busily engaged in studying the
tortoiseshell comb which Miss Wallace in her weakness had forgotten.

The little shopkeeper let us in sleepily and Kennedy deposited a large
round package on a chair in the back of the shop, as well as a long
piece of rubber tubing. Nothing had happened so far.

As we waited the shopkeeper, now wide awake and not at all unconvinced
that we were bent on some criminal operation, hung around. Kennedy did
not seem to care. He drew from his pocket a little shiny brass
instrument in a lead case, which looked like an abbreviated microscope.

"Look through it," he said, handing it to me.

I looked and could see thousands of minute sparks.

"What is it?" I asked.

"A spinthariscope. In that it is possible to watch the bombardment of
the countless little corpuscles thrown off by radium, as they strike on
the zinc blende crystal which forms the base. When radium was
originally discovered, the interest was merely in its curious
properties, its power to emit invisible rays which penetrated solid
substances and rendered things fluorescent, of expending energy without
apparent loss.

"Then came the discovery," he went on, "of its curative powers. But the
first results were not convincing. Still, now that we know the reasons
why radium may be dangerous and how to protect ourselves against them
we know we possess one of the most wonderful of curative agencies."

I was thinking rather of the dangers than of the beneficence of radium
just now, but Kennedy continued.

"It has cured many malignant growths that seemed hopeless, brought back
destroyed cells, exercised good effects in diseases of the liver and
intestines and even the baffling diseases of the arteries. The reason
why harm, at first, as well as good came, is now understood. Radium
emits, as I told you before, three kinds of rays, the alpha, beta, and
gamma rays, each with different properties. The emanation is another
matter. It does not concern us in this case, as you will see."

Fascinated as I was by the mystery of the case, I began to see that he
was gradually arriving at an explanation which had baffled everyone
else.

"Now, the alpha rays are the shortest," he launched forth, "in length
let us say one inch. They exert a very destructive effect on healthy
tissue. That is the cause of injury. They are stopped by glass,
aluminum and other metals, and are really particles charged with
positive electricity. The beta rays come next, say, about an inch and a
half. They stimulate cell growth. Therefore they are dangerous in
cancer, though good in other ways. They can be stopped by lead, and are
really particles charged with negative electricity. The gamma rays are
the longest, perhaps three inches long, and it is these rays which
effect cures, for they check the abnormal and stimulate the normal
cells. They penetrate lead. Lead seems to filter them out from the
other rays. And at three inches the other rays don't reach, anyhow. The
gamma rays are not charged with electricity at all, apparently."

He had brought a little magnet near the spinthariscope. I looked into
it.

"A magnet," he explained, "shows the difference between the alpha,
beta, and gamma rays. You see those weak and wobbly rays that seem to
fall to one side? Those are the alpha rays. They have a strong action,
though, on tissues and cells. Those falling in the other direction are
the beta rays. The gamma rays seem to flow straight."

"Then it is the alpha rays with which we are concerned mostly now?" I
queried, looking up.

"Exactly. That is why, when radium is unprotected or insufficiently
protected and comes too near, it is destructive of healthy cells,
produces burns, sores, which are most difficult to heal. It is with the
explanation of such sores that we must deal."

It was growing late. We had waited patiently now for some time. Kennedy
had evidently reserved this explanation, knowing we should have to
wait. Still nothing happened.

Added to the mystery of the violet-colored glass plate was now that of
the luminescent diamond. I was about to ask Kennedy point-blank what he
thought of them, when suddenly the little bell before us began to buzz
feebly under the influence of a current.

I gave a start. The faithful little selenium cell burglar alarm had
done the trick. I knew that selenium was a good conductor of
electricity in the light, poor in the dark. Some one had, therefore,
flashed a light on one of the cells in the Corporation office. It was
the moment for which Kennedy had prepared.

Seizing the round package and the tubing, he dashed out on the street
and around the corner. He tried the door opening into the Radium
Corporation hallway. It was closed, but unlocked. As it yielded and we
stumbled in, up the old worn wooden stairs of the building, I knew that
there must be some one there.

A terrific, penetrating, almost stunning odor seemed to permeate the
air even in the hall.

Kennedy paused at the door of the office, tried it, found it unlocked,
but did not open it.

"That smell is ethyldichloracetate," he explained. "That was what I
injected into the air cushion of that safe between the two linings. I
suppose my man here used an electric drill. He might have used thermit
or an oxyacetylene blowpipe for all I would care. These fumes would
discourage a cracksman from 'soup' to nuts," he laughed, thoroughly
pleased at the protection modern science had enabled him to devise.

As we stood an instant by the door, I realized what had happened. We
had captured our man. He was asphyxiated!

Yet how were we to get to him? Would Craig leave him in there, perhaps
to die? To go in ourselves meant to share his fate, whatever might be
the effect of the drug.

Kennedy had torn the wrapping off the package. From it he drew a huge
globe with bulging windows of glass in the front and several curious
arrangements on it at other points. To it he fitted the rubber tubing
and a little pump. Then he placed the globe over his head, like a
diver's helmet, and fastened some air-tight rubber arrangement about
his neck and shoulders.

"Pump, Walter!" he shouted. "This is an oxygen helmet such as is used
in entering mines filled with deadly gases."

Without another word he was gone into the blackness of the noxious
stifle which filled the Radium Corporation office since the cracksman
had struck the unexpected pocket of rapidly evaporating stuff.

I pumped furiously.

Inside I could hear him blundering around. What was he doing?

He was coming back slowly. Was he, too, overcome?

As he emerged into the darkness of the hallway where I myself was
almost sickened, I saw that he was dragging with him a limp form.

A rush of outside air from the street door seemed to clear things a
little. Kennedy tore off the oxygen helmet and dropped down on his
knees beside the figure, working its arms in the most approved manner
of resuscitation.

"I think we can do it without calling on the pulmotor," he panted.
"Walter, the fumes have cleared away enough now in the outside office.
Open a window--and keep that street door open, too."

I did so, found the switch and turned on the lights.

It was Denison himself!

For many minutes Kennedy worked over him. I bent down, loosened his
collar and shirt, and looked eagerly at his chest for the tell-tale
marks of the radium which I felt sure must be there. There was not even
a discoloration.

Not a word was said, as Kennedy brought the stupefied little man around.

Denison, pale, shaken, was leaning back now in a big office chair,
gasping and holding his head.

Kennedy, before him, reached down into his pocket and handed him the
spinthariscope.

"You see that?" he demanded.

Denison looked through the eyepiece.

"Wh--where did you get so much of it?" he asked, a queer look on his
face.

"I got that bit of radium from the base of the collar button of Hartley
Haughton," replied Kennedy quietly, "a collar button which some one
intimate with him had substituted for his own, bringing that deadly
radium with only the minutest protection of a thin strip of metal close
to the back of his neck, near the spinal cord and the medulla oblongata
which controls blood pressure. That collar button was worse than the
poisoned rings of the Borgias. And there is more radium in the pretty
gift of a tortoiseshell comb with its paste diamonds which Miss Wallace
wore in her hair. Only a fraction of an inch, not enough to cut off the
deadly alpha rays, protected the wearers of those articles."

He paused a moment, while surging through my mind came one after
another the explanations of the hitherto inexplicable. Denison seemed
almost to cringe in the chair, weak already from the fumes.

"Besides," went on Kennedy remorselessly, "when I went in there to drag
you out, I saw the safe open. I looked. There was nothing in those
pretty platinum tubes, as I suspected. European trust--bah! All the
cheap devices of a faker with a confederate in London to send a
cablegram--and another in New York to send a threatening letter."

Kennedy extended an accusing forefinger at the man cowering before him.

"This is nothing but a get-rich-quick scheme, Denison. There never was
a milligram of radium in the Poor Little Rich Valley, not a milligram
here in all the carefully kept reports of Miss Wallace--except what was
bought outside by the Corporation with the money it collected from its
dupes. Haughton has been fleeced. Miss Wallace, blinded by her loyalty
to you--you will always find such a faithful girl in such schemes as
yours--has been fooled.

"And how did you repay it? What was cleverer, you said to yourself,
than to seem to be robbed of what you never had, to blame it on a
bitter rival who never existed? Then to make assurance doubly sure, you
planned to disable, perhaps get rid of the come-on whom you had
trimmed, and the faithful girl whose eyes you had blinded to your
gigantic swindle.

"Denison," concluded Kennedy, as the man drew back, his very face
convicting him, "Denison, you are the radium robber--robber in another
sense!"



CHAPTER XVI

THE DEAD LINE


Maiden Lane, no less than Wall Street, was deeply interested in the
radium case. In fact, it seemed that one case in this section of the
city led to another.

Naturally, the Star and the other papers made much of the capture of
Denison. Still, I was not prepared for the host of Maiden Lane cases
that followed. Many of them were essentially trivial. But one proved to
be of extreme importance.

"Professor Kennedy, I have just heard of your radium case, and I--I
feel that I can--trust you."

There was a note of appeal in the hesitating voice of the tall, heavily
veiled woman whose card had been sent up to us with a nervous "Urgent"
written across its face.

It was very early in the morning, but our visitor was evidently
completely unnerved by some news which she had just received and which
had sent her posting to see Craig.

Kennedy met her gaze directly with a look that arrested her involuntary
effort to avoid it again. She must have read in his eyes more than in
his words that she might trust him.

"I--I have a confession to make," she faltered.

"Please sit down, Mrs. Moulton," he said simply. "It is my business to
receive confidences--and to keep them."

She sank into, rather than sat down in, the deep leather rocker beside
his desk, and now for the first time raised her veil.

Antoinette Moulton was indeed stunning, an exquisite creature with a
wonderful charm of slender youth, brightness of eye and brunette
radiance.

I knew that she had been on the musical comedy stage and had had a
rapid rise to a star part before her marriage to Lynn Moulton, the
wealthy lawyer, almost twice her age. I knew also that she had given up
the stage, apparently without a regret. Yet there was something strange
about the air of secrecy of her visit. Was there a hint in it of a
disagreement between the Moultons, I wondered, as I waited while
Kennedy reassured her.

Her distress was so unconcealed that Craig, for the moment, laid aside
his ordinary inquisitorial manner. "Tell me just as much or just as
little as you choose, Mrs. Moulton," he added tactfully. "I will do my
best."

A look almost of gratitude crossed her face.

"When we were married," she began again, "my husband gave me a
beautiful diamond necklace. Oh, it must have been worth a hundred
thousand dollars easily. It was splendid. Everyone has heard of it. You
know, Lynn--er--Mr. Moulton, has always been an enthusiastic collector
of jewels."

She paused again and Kennedy nodded reassuringly. I knew the thought in
his mind. Moulton had collected one gem that was incomparable with all
the hundred thousand dollar necklaces in existence.

"Several months ago." she went on rapidly, still avoiding his eyes and
forcing the words from her reluctant lips, "I--oh, I needed
money--terribly."

She had risen and faced him, pressing her daintily gloved hands
together in a little tremble of emotion which was none the less genuine
because she had studied the art of emotion.

"I took the necklace to a jeweler, Herman Schloss, of Maiden Lane, a
man with whom my husband had often had dealings and whom I thought I
could trust. Under a promise of secrecy he loaned me fifty thousand
dollars on it and had an exact replica in paste made by one of his best
workmen. This morning, just now, Mr. Schloss telephoned me that his
safe had been robbed last night. My necklace is gone!"

She threw out her hands in a wildly appealing gesture.

"And if Lynn finds that the necklace in our wall safe is of paste--as
he will find, for he is an expert in diamonds--oh--what shall I do?
Can't you--can't you find my necklace?"

Kennedy was following her now eagerly. "You were blackmailed out of the
money?" he queried casually, masking his question.

There was a sudden, impulsive drooping of her mouth, an evasion and
keen wariness in her eyes. "I can't see that that has anything to do
with the robbery," she answered in a low voice.

"I beg your pardon," corrected Kennedy quickly. "Perhaps not. I'm
sorry. Force of habit, I suppose. You don't know anything more about
the robbery?"

"N--no, only that it seems impossible that it could have happened in a
place that has the wonderful burglar alarm protection that Mr. Schloss
described to me."

"You know him pretty well?"

"Only through this transaction," she replied hastily. "I wish to heaven
I had never heard of him."

The telephone rang insistently.

"Mrs. Moulton," said Kennedy, as he returned the receiver to the hook,
"it may interest you to know that the burglar alarm company has just
called me up about the same case. If I had need of an added incentive,
which I hope you will believe I have not, that might furnish it. I will
do my best," he repeated.

"Thank you--a thousand times," she cried fervently, and, had I been
Craig, I think I should have needed no more thanks than the look she
gave him as he accompanied her to the door of our apartment.

It was still early and the eager crowds were pushing their way to
business through the narrow network of downtown streets as Kennedy and
I entered a large office on lower Broadway in the heart of the jewelry
trade and financial district.

"One of the most amazing robberies that has ever been attempted has
been reported to us this morning," announced James McLear, manager of
the Hale Electric Protection, adding with a look half of anxiety, half
of skepticism, "that is, if it is true."

McLear was a stocky man, of powerful build and voice and a general
appearance of having been once well connected with the city detective
force before an attractive offer had taken him into this position of
great responsibility.

"Herman Schloss, one of the best known of Maiden Lane jewelers," he
continued, "has been robbed of goods worth two or three hundred
thousand dollars--and in spite of every modern protection. So that you
will get it clearly, let me show you what we do here."

He ushered us into a large room, on the walls of which were hundreds of
little indicators. From the front they looked like rows of little
square compartments, tier on tier, about the size of ordinary post
office boxes. Closer examination showed that each was equipped with a
delicate needle arranged to oscillate backward and forward upon the
very minutest interference with the electric current. Under the boxes,
each of which bore a number, was a series of drops and buzzers numbered
to correspond with the boxes.

"In nearly every office in Maiden Lane where gems and valuable jewelry
are stored," explained McLear, "this electrical system of ours is
installed. When the safes are closed at night and the doors swung
together, a current of electricity is constantly shooting around the
safes, conducted by cleverly concealed wires. These wires are picked up
by a cable system which finds its way to this central office. Once
here, the wires are safeguarded in such manner that foreign currents
from other wires or from lightning cannot disturb the system."

We looked with intense interest at this huge electrical pulse that felt
every change over so vast and rich an area.

"Passing a big dividing board," he went on, "they are distributed and
connected each in its place to the delicate tangent galvanometers and
sensitive indicators you see in this room. These instantly announce the
most minute change in the working of the current, and each office has a
distinct separate metallic circuit. Why, even a hole as small as a lead
pencil in anything protected would sound the alarm here."

Kennedy nodded appreciatively.

"You see," continued McLear, glad to be able to talk to one who
followed him so closely, "it is another evidence of science finding for
us greater security in the use of a tiny electric wire than in massive
walls of steel and intricate lock devices. But here is a case in which,
it seems, every known protection has failed. We can't afford to pass
that by. If we have fallen down we want to know how, as well as to
catch the burglar."

"How are the signals given?" I asked.

"Well, when the day's business is over, for instance, Schloss would
swing the heavy safe doors together and over them place the doors of a
wooden cabinet. That signals an alarm to us here. We answer it and if
the proper signal is returned, all right. After that no one can tamper
with the safe later in the night without sounding an alarm that would
bring a quick investigation."

"But suppose that it became necessary to open the safe before the next
morning. Might not some trusted employee return to the office, open it,
give the proper signals and loot the safe?"

"No indeed," he answered confidently. "The very moment anyone touches
the cabinet, the alarm is sounded. Even if the proper code signal is
returned, it is not sufficient. A couple of our trusted men from the
central office hustle around there anyhow and they don't leave until
they are satisfied that everything is right. We have the authorized
signatures on hand of those who are supposed to open the safe and a
duplicate of one of them must be given or there is an arrest."

McLear considered for a moment.

"For instance, Schloss, like all the rest, was assigned a box in which
was deposited a sealed envelope containing a key to the office and his
own signature, in this case, since he alone knew the combination. Now,
when an alarm is sounded, as it was last night, and the key removed to
gain entrance to the office, a record is made and the key has to be
sealed up again by Schloss. A report is also submitted showing when the
signals are received and anything else that is worth recording. Last
night our men found nothing wrong, apparently. But this morning we
learn of the robbery."

"The point is, then," ruminated Kennedy, "what happened in the interval
between the ringing of the alarm and the arrival of the special
officers? I think I'll drop around and look Schloss' place over," he
added quietly, evidently eager to begin at the actual scene of the
crime.

On the door of the office to which McLear took us was one of those
small blue plates which chance visitors to Maiden Lane must have seen
often. To the initiated--be he crook or jeweler--this simple sign means
that the merchant is a member of the Jewelers' Security Alliance,
enough in itself, it would seem, to make the boldest burglar hesitate.
For it is the motto of this organization to "get" the thief at any cost
and at any time. Still, it had not deterred the burglar in this
instance.

"I know people are going to think it is a fake burglary," exclaimed
Schloss, a stout, prosperous-looking gem broker, as we introduced
ourselves. "But over two hundred thousands dollars' worth of stones are
gone," he half groaned. "Think of it, man," he added, "one of the
greatest robberies since the Dead Line was established. And if they can
get away with it, why, no one down here is protected any more. Half a
billion dollars in jewels in Maiden Lane and John Street are easy prey
for the cracksmen!"

Staggering though the loss must have been to him, he had apparently
recovered from the first shock of the discovery and had begun the fight
to get back what had been lost.

It was, as McLear had intimated, a most amazing burglary, too. The door
of Schloss' safe was open when Kennedy and I arrived and found the
excited jeweler nervously pacing the office. Surrounding the safe, I
noticed a wooden framework constructed in such a way as to be a part of
the decorative scheme of the office.

Schloss banged the heavy doors shut.

"There, that's just how it was--shut as tight as a drum. There was
absolutely no mark of anyone tampering with the combination lock. And
yet the safe was looted!"

"How did you discover it?" asked Craig. "I presume you carry burglary
insurance?"

Schloss looked up quickly. "That's what I expected as a first question.
No, I carried very little insurance. You see, I thought the safe, one
of those new chrome steel affairs, was about impregnable. I never lost
a moment's sleep over it; didn't think it possible for anyone to get
into it. For, as you see, it is completely wired by the Hale Electric
Protection--that wooden framework about it. No one could touch that
when it was set without jangling a bell at the central office which
would send men scurrying here to protect the place."

"But they must have got past it," suggested Kennedy.

"Yes--they must have. At least this morning I received the regular Hale
report. It said that their wires registered last night as though some
one was tampering with the safe. But by the time they got around, in
less than five minutes, there was no one here, nothing seemed to be
disturbed. So they set it down to induction or electrolysis, or
something the matter with the wires. I got the report the first thing
when I arrived here with my assistant, Muller."

Kennedy was on his knees, going over the safe with a fine brush and
some powder, looking now and then through a small magnifying glass.

"Not a finger print," he muttered. "The cracksman must have worn
gloves. But how did he get in? There isn't a mark of 'soup' having been
used to blow it up, nor of a 'can-opener' to rip it open, if that were
possible, nor of an electric or any other kind of drill."

"I've read of those fellows who burn their way in," said Schloss.

"But there is no hole," objected Kennedy, "not a trace of the use of
thermit to burn the way in or of the oxyacetylene blowpipe to cut a
piece out. Most extraordinary," he murmured.

"You see," shrugged Schloss, "everyone will say it must have been
opened by one who knew the combination. But I am the only one. I have
never written it down or told anyone, not even Muller. You understand
what I am up against?"

"There's the touch system," I suggested. "You remember, Craig, the old
fellow who used to file his finger tips to the quick until they were so
sensitive that he could actually feel when he had turned the
combination to the right plunger? Might not that explain the lack of
finger prints also?" I added eagerly.

"Nothing like that in this case, Walter," objected Craig positively.
"This fellow wore gloves, all right. No, this safe has been opened and
looted by no ordinarily known method. It's the most amazing case I ever
saw in that respect--almost as if we had a cracksman in the fourth
dimension to whom the inside of a closed cube is as accessible as is
the inside of a plane square to us three dimensional creatures. It is
almost incomprehensible."

I fancied I saw Schloss' face brighten as Kennedy took this view. So
far, evidently, he had run across only skepticism.

"The stones were unset?" resumed Craig.

"Mostly. Not all."

"You would recognize some of them if you saw them?"

"Yes indeed. Some could be changed only by re-cutting. Even some of
those that were set were of odd cut and size--some from a diamond
necklace which belonged to a--"

There was something peculiar in both his tone and manner as he cut
short the words.

"To whom?" asked Kennedy casually.

"Oh, once to a well-known woman in society," he said carefully. "It is
mine, though, now--at least it was mine. I should prefer to mention no
names. I will give a description of the stones."

"Mrs. Lynn Moulton, for instance?" suggested Craig quietly.

Schloss jumped almost as if a burglar alarm had sounded under his very
ears. "How did you know? Yes--but it was a secret. I made a large loan
on it, and the time has expired."

"Why did she need money so badly?" asked Kennedy.

"How should I know?" demanded Schloss.

Here was a deepening mystery, not to be elucidated by continuing this
line of inquiry with Schloss, it seemed.



CHAPTER XVII

THE PASTE REPLICA


Carefully Craig was going over the office. Outside of the safe, there
had apparently been nothing of value. The rest of the office was not
even wired, and it seemed to have been Schloss' idea that the few
thousands of burglary insurance amply protected him against such loss.
As for the safe, its own strength and the careful wiring might well
have been considered quite sufficient under any hitherto to-be-foreseen
circumstances.

A glass door, around the bend of a partition, opened from the hallway
into the office and had apparently been designed with the object of
making visible the safe so that anyone passing might see whether an
intruder was tampering with it.

Kennedy had examined the door, perhaps in the expectation of finding
finger prints there, and was passing on to other things, when a change
in his position caused his eye to catch a large oval smudge on the
glass, which was visible when the light struck it at the right angle.
Quickly he dusted it over with the powder, and brought out the detail
more clearly. As I examined it, while Craig made preparations to cut
out the glass to preserve it, it seemed to contain a number of minute
points and several more or less broken parallel lines. The edges
gradually trailed off into an indistinct faintness.

Business, naturally, was at a standstill, and as we were working near
the door, we could see that the news of Schloss' strange robbery had
leaked out and was spreading rapidly. Scores of acquaintances in the
trade stopped at the door to inquire about the rumor.

To each, it seemed that Morris Muller, the working jeweler employed by
Schloss, repeated the same story.

"Oh," he said, "it is a big loss--yes--but big as it is, it will not
break Mr. Schloss. And," he would add with the tradesman's idea of
humor, "I guess he has enough to play a game of poker--eh?"

"Poker?" asked Kennedy smiling. "Is he much of a player?"

"Yes. Nearly every night with his friends he plays."

Kennedy made a mental note of it. Evidently Schloss trusted Muller
implicitly. He seemed like a partner, rather than an employee, even
though he had not been entrusted with the secret combination.

Outside, we ran into city detective Lieutenant Winters, the officer who
was stationed at the Maiden Lane post, guarding that famous section of
the Dead Line established by the immortal Byrnes at Fulton Street,
below which no crook was supposed to dare even to be seen. Winters had
been detailed on the case.

"You have seen the safe in there?" asked Kennedy, as he was leaving to
carry on his investigation elsewhere.

Winters seemed to be quite as skeptical as Schloss had intimated the
public would be. "Yes," he replied, "there's been an epidemic of
robbery with the dull times--people who want to collect their burglary
insurance, I guess."

"But," objected Kennedy, "Schloss carried so little."

"Well, there was the Hale Protection. How about that?"

Craig looked up quickly, unruffled by the patronizing air of the
professional toward the amateur detective.

"What is your theory?" he asked. "Do you think he robbed himself?"

Winters shrugged his shoulders. "I've been interested in Schloss for
some time," he said enigmatically. "He has had some pretty swell
customers. I'll keep you wised up, if anything happens," he added in a
burst of graciousness, walking off.

On the way to the subway, we paused again to see McLear.

"Well," he asked, "what do you think of it, now?"

"All most extraordinary," ruminated Craig. "And the queerest feature of
all is that the chief loss consists of a diamond necklace that belonged
once to Mrs. Antoinette Moulton."

"Mrs. Lynn Moulton?" repeated McLear.

"The same," assured Kennedy.

McLear appeared somewhat puzzled. "Her husband is one of our old
subscribers," he pursued. "He is a lawyer on Wall Street and quite a
gem collector. Last night his safe was tampered with, but this morning
he reports no loss. Not half an hour ago he had us on the wire
congratulating us on scaring off the burglars, if there had been any."

"What is your opinion," I asked. "Is there a gang operating?"

"My belief is," he answered, reminiscently of his days on the detective
force, "that none of the loot will be recovered until they start to
'fence' it. That would be my lay--to look for the fence. Why, think of
all the big robberies that have been pulled off lately. Remember," he
went on, "the spoils of a burglary consist generally of precious
stones. They are not currency. They must be turned into currency--or
what's the use of robbery?

"But merely to offer them for sale at an ordinary jeweler's would be
suspicious. Even pawnbrokers are on the watch. You see what I am
driving at? I think there is a man or a group of men whose business it
is to pay cash for stolen property and who have ways of returning gems
into the regular trade channels. In all these robberies we get a
glimpse of as dark and mysterious a criminal as has ever been recorded.
He may be--anybody. About his legitimacy, I believe, no question has
ever been raised. And, I tell you, his arrest is going to create a
greater sensation than even the remarkable series of robberies that he
has planned or made possible. The question is, to my mind, who is this
fence?"

McLear's telephone rang and he handed the instrument to Craig.

"Yes, this is Professor Kennedy," answered Craig. "Oh, too bad you've
had to try all over to get me. I've been going from one place to
another gathering clues and have made good progress, considering I've
hardly started. Why--what's the matter? Really?"

An interval followed, during which McLear left to answer a personal
call on another wire.

As Kennedy hung up the receiver, his face wore a peculiar look. "It was
Mrs. Moulton," he blurted out. "She thinks that her husband has found
out that the necklace is paste."

"How?" I asked.

"The paste replica is gone from her wall safe in the Deluxe."

I turned, startled at the information. Even Kennedy himself was
perplexed at the sudden succession of events. I had nothing to say.

Evidently, however, his rule was when in doubt play a trump, for,
twenty minutes later found us in the office of Lynn Moulton, the famous
corporation lawyer, in Wall Street.

Moulton was a handsome man of past fifty with a youthful face against
his iron gray hair and mustache, well dressed, genial, a man who seemed
keenly in love with the good things of life.

"It is rumored," began Kennedy, "that an attempt was made on your safe
here at the office last night."

"Yes," he admitted, taking off his glasses and polishing them
carefully. "I suppose there is no need of concealment, especially as I
hear that a somewhat similar attempt was made on the safe of my friend
Herman Schloss in Maiden Lane."

"You lost nothing?"

Moulton put his glasses on and looked Kennedy in the face frankly.

"Nothing, fortunately," he said, then went on slowly. "You see, in my
later years, I have been something of a collector of precious stones
myself. I don't wear them, but I have always taken the keenest pleasure
in owning them and when I was married it gave me a great deal more
pleasure to have them set in rings, pendants, tiaras, necklaces, and
other forms for my wife."

He had risen, with the air of a busy man who had given the subject all
the consideration he could afford and whose work proceeded almost by
schedule. "This morning I found my safe tampered with, but, as I said,
fortunately something must have scared off the burglars."

He bowed us out politely. What was the explanation, I wondered. It
seemed, on the face of things, that Antoinette Moulton feared her
husband. Did he know something else already, and did she know he knew?
To all appearances he took it very calmly, if he did know. Perhaps that
was what she feared, his very calmness.

"I must see Mrs. Moulton again," remarked Kennedy, as we left.

The Moultons lived, we found, in one of the largest suites of a new
apartment hotel, the Deluxe, and in spite of the fact that our arrival
had been announced some minutes before we saw Mrs. Moulton, it was
evident that she had been crying hysterically over the loss of the
paste jewels and what it implied.

"I missed it this morning, after my return from seeing you," she
replied in answer to Craig's inquiry, then added, wide-eyed with alarm,
"What shall I do? He must have opened the wall safe and found the
replica. I don't dare ask him point-blank."

"Are you sure he did it?" asked Kennedy, more, I felt, for its moral
effect on her than through any doubt in his own mind.

"Not sure. But then the wall safe shows no marks, and the replica is
gone."

"Might I see your jewel case?" he asked.

"Surely. I'll get it. The wall safe is in Lynn's room. I shall probably
have to fuss a long time with the combination."

In fact she could not have been very familiar with it for it took
several minutes before she returned. Meanwhile, Kennedy, who had been
drumming absently on the arms of his chair, suddenly rose and walked
quietly over to a scrap basket that stood beside an escritoire. It had
evidently just been emptied, for the rooms must have been cleaned
several hours before. He bent down over it and picked up two scraps of
paper adhering to the wicker work. The rest had evidently been thrown
away.

I bent over to read them. One was:

           --rest Nettie--
           --dying to see--

The other read:

           --cherche to-d
           --love and ma
           --rman.

What did it mean? Hastily, I could fill in "Dearest Nettie," and "I am
dying to see you." Kennedy added, "The Recherche to-day," that being
the name of a new apartment uptown, as well as "love and many kisses."
But "--rman"--what did that mean? Could it be Herman--Herman Schloss?

She was returning and we resumed our seats quickly.

Kennedy took the jewel case from her and examined it carefully. There
was not a mark on it.

"Mrs. Moulton," he said slowly, rising and handing it back to her,
"have you told me all?"

"Why--yes," she answered.

Kennedy shook his head gravely.

"I'm afraid not. You must tell me everything."

"No--no," she cried vehemently, "there is nothing more."

We left and outside the Deluxe he paused, looked about, caught sight of
a taxicab and hailed it.

"Where?" asked the driver.

"Across the street," he said, "and wait. Put the window in back of you
down so I can talk. I'll tell you where to go presently. Now, Walter,
sit back as far as you can. This may seem like an underhand thing to
do, but we've got to get what that woman won't tell us or give up the
case."

Perhaps half an hour we waited, still puzzling over the scraps of
paper. Suddenly I felt a nudge from Kennedy. Antoinette Moulton was
standing in the doorway across the street. Evidently she preferred not
to ride in her own car, for a moment later she entered a taxicab.

"Follow that black cab," said Kennedy to our driver.

Sure enough, it stopped in front of the Recherche Apartments and Mrs.
Moulton stepped out and almost ran in.

We waited a moment, then Kennedy followed. The elevator that had taken
her up had just returned to the ground floor.

"The same floor again," remarked Kennedy, jauntily stepping in and
nodding familiarly to the elevator boy.

Then he paused suddenly, looked at his watch, fixed his gaze
thoughtfully on me an instant, and exclaimed. "By George--no. I can't
go up yet. I clean forgot that engagement at the hotel. One moment,
son. Let us out. We'll be back again."

Considerably mystified, I followed him to the sidewalk.

"You're entitled to an explanation," he laughed catching my bewildered
look as he opened the cab door. "I didn't want to go up now while she
is there, but I wanted to get on good terms with that boy. We'll wait
until she comes down, then go up."

"Where?" I asked.

"That's what I am going through all this elaborate preparation to find
out. I have no more idea than you have."

It could not have been more than twenty minutes later when Mrs. Moulton
emerged rather hurriedly, and drove away.

While we had been waiting I had observed a man on the other side of the
street who seemed unduly interested in the Recherche, too, for he had
walked up and down the block no less than six times. Kennedy saw him,
and as he made no effort to follow Mrs. Moulton, Kennedy did not do so
either. In fact a little quick glance which she had given at our cab
had raised a fear that she might have discovered that she was being
followed.

Kennedy and I paid off our cabman and sauntered into the Recherche in
the most debonair manner we could assume.

"Now, son, we'll go up," he said to the boy who, remembering us, and
now not at all clear in his mind that he might not have seen us before
that, whisked us to the tenth floor.

"Let me see," said Kennedy, "it's number one hundred and--er---"

"Three," prompted the boy.

He pressed the buzzer and a neatly dressed colored maid responded.

"I had an appointment here with Mrs. Moulton this morning," remarked
Kennedy.

"She has just gone," replied the maid, off her guard.

"And was to meet Mr. Schloss here in half an hour," he added quickly.

It was the maid's turn to look surprised.

"I didn't think he was to be here," she said. "He's had some--"

"Trouble at the office," supplied Kennedy. "That's what it was about.
Perhaps he hasn't been able to get away yet. But I had the appointment.
Ah, I see a telephone in the hall. May I?"

He had stepped politely in, and by dint of cleverly keeping his finger
on the hook in the half light, he carried on a one-sided conversation
with himself long enough to get a good chance to look about.

There was an air of quiet and refinement about the apartment in the
Recherche. It was darkened to give the little glowing electric bulbs in
their silken shades a full chance to simulate right. The deep velvety
carpets were noiseless to the foot, and the draperies, the pictures,
the bronzes, all bespoke taste.

But the chief objects of interest to Craig were the little square green
baize-covered tables on one of which lay neatly stacked a pile of
gilt-edged cards and a mahogany box full of ivory chips of red, white
and blue.

It was none of the old-time gambling places, like Danfield's, with its
steel door which Craig had once cut through with an oxyacetylene
blowpipe in order to rescue a young spendthrift from himself.

Kennedy seemed perfectly well satisfied merely with a cursory view of
the place, as he hung up the receiver and thanked the maid politely for
allowing him to use it.

"This is up-to-date gambling in cleaned-up New York," he remarked as we
waited for the elevator to return for us. "And the worst of it all is
that it gets the women as well as the men. Once they are caught in the
net, they are the most powerful lure to men that the gamblers have yet
devised."

We rode down in silence, and as we went down the steps to the street, I
noticed the man whom we had seen watching the place, lurking down at
the lower corner. Kennedy quickened his pace and came up behind him.

"Why, Winters!" exclaimed Craig. "You here?"

"I might say the same to you," grinned the detective not displeased
evidently that our trail had crossed his. "I suppose you are looking
for Schloss, too. He's up in the Recherche a great deal, playing poker.
I understand he owns an interest in the game up there."

Kennedy nodded, but said nothing.

"I just saw one of the cappers for the place go out before you went in."

"Capper?" repeated Kennedy surprised. "Antoinette Moulton a steerer for
a gambling joint? What can a rich society woman have to do with a place
like that or a man like Schloss?"

Winters smiled sardonically. "Society ladies to-day often get into
scrapes of which their husbands know nothing," he remarked. "You didn't
know before that Antoinette Moulton, like many of her friends in the
smart set, was a gambler--and loser--did you?"

Craig shook his head. He had more of human than scientific interest in
a case of a woman of her caliber gone wrong.

"But you must have read of the famous Moulton diamonds?"

"Yes," said Craig, blankly, as if it were all news to him.

"Schloss has them--or at least had them. The jewels she wore at the
opera this winter were paste, I understand."

"Does Moulton play?" he asked.

"I think so--but not here, naturally. In a way, I suppose, it is his
fault. They all do it. The example of one drives on another."

Instantly there flashed over my mind a host of possibilities. Perhaps,
after all, Winters had been right. Schloss had taken this way to make
sure of the jewels so that she could not redeem them. Suddenly another
explanation crowded that out. Had Mrs. Moulton robbed the safe herself,
or hired some one else to do it for her, and had that person gone back
on her?

Then a horrid possibility occurred to me. Whatever Antoinette Moulton
may have been and done, some one must have her in his power. What a
situation for the woman! My sympathy went out to her in her supreme
struggle. Even if it had been a real robbery, Schloss might easily
recover from it. But for her every event spelled ruin and seemed only
to be bringing that ruin closer.

We left Winters, still watching on the trail of Schloss, and went on
uptown to the laboratory.



CHAPTER XVIII

THE BURGLAR'S MICROPHONE


That night I was sitting, brooding over the case, while Craig was
studying a photograph which he made of the smudge on the glass door
down at Schloss'. He paused in his scrutiny of the print to answer the
telephone.

"Something has happened to Schloss," he exclaimed seizing his hat and
coat. "Winters has been watching him. He didn't go to the Recherche.
Winters wants me to meet him at a place several blocks below it Come
on. He wouldn't say over the wire what it was. Hurry."

We met Winters in less than ten minutes at the address he had given, a
bachelor apartment in the neighborhood of the Recherche.

"Schloss kept rooms here," explained Winters, hurrying us quickly
upstairs. "I wanted you to see before anyone else."

As we entered the large and luxuriously furnished living room of the
jeweler's suite, a gruesome sight greeted us.

There lay Schloss on the floor, face down, in a horribly contorted
position. In one hand, clenched under him partly, the torn sleeve of a
woman's dress was grasped convulsively. The room bore unmistakable
traces of a violent struggle, but except for the hideous object on the
floor was vacant.

Kennedy bent down over him. Schloss was dead. In a corner, by the door,
stood a pile of grips, stacked up, packed, and undisturbed.

Winters who had been studying the room while we got our bearings picked
up a queer-looking revolver from the floor. As he held it up I could
see that along the top of the barrel was a long cylinder with a ratchet
or catch at the butt end. He turned it over and over carefully.

"By George," he muttered, "it has been fired off."

Kennedy glanced more minutely at the body. There was not a mark on it.
I stared about vacantly at the place where Winters had picked the thing
up.

"Look," I cried, my eye catching a little hole in the baseboard of the
woodwork near it.

"It must have fallen and exploded on the floor," remarked Kennedy. "Let
me see it, Winters."

Craig held it at arm's length and pulled the catch. Instead of an
explosion, there came a cone of light from the top of the gun. As
Kennedy moved it over the wall, I saw in the center of the circle of
light a dark spot.

"A new invention," Craig explained. "All you need to do is to move it
so that little dark spot falls directly on an object. Pull the
trigger--the bullet strikes the dark spot. Even a nervous and unskilled
marksman becomes a good shot in the dark. He can even shoot from behind
the protection of something--and hit accurately."

It was too much for me. I could only stand and watch Kennedy as he
deftly bent over Schloss again and placed a piece of chemically
prepared paper flat on the forehead of the dead man.

When he withdrew it, I could see that it bore marks of the lines on his
head. Without a word, Kennedy drew from his pocket a print of the
photograph of the smudge on Schloss' door.

"It is possible," he said, half to himself, "to identify a person by
means of the arrangement of the sweat glands or pores. Poroscopy, Dr.
Edmond Locard, director of the Police Laboratory at Lyons, calls it.
The shape, arrangement, number per square centimeter, all vary in
different individuals. Besides, here we have added the lines of the
forehead."

He was studying the two impressions intensely. When he looked up from
his examination, his face wore a peculiar expression.

"This is not the head which was placed so close to the glass of the
door of Schloss' office, peering through, on the night of the robbery,
in order to see before picking the lock whether the office was empty
and everything ready for the hasty attack on the safe."

"That disposes of my theory that Schloss robbed himself," remarked
Winters reluctantly. "But the struggle here, the sleeve of the dress,
the pistol--could he have been shot?"

"No, I think not," considered Kennedy. "It looks to me more like a case
of apoplexy."

"What shall we do?" asked Winters. "Far from clearing anything up, this
complicates it."

"Where's Muller?" asked Kennedy. "Does he know? Perhaps he can shed
some light on it."

The clang of an ambulance bell outside told that the aid summoned by
Winters had arrived.

We left the body in charge of the surgeon and of a policeman who
arrived about the same time, and followed Winters.

Muller lived in a cheap boarding house in a shabbily respectable street
downtown, and without announcing ourselves we climbed the stairs to his
room. He looked up surprised but not disconcerted as we entered.

"What's the matter?" he asked.

"Muller," shot out Winters, "we have just found Mr. Schloss dead!"

"D-dead!" he stammered.

The man seemed speechless with horror.

"Yes, and with his grips packed as if to run away."

Muller looked dazedly from one of us to the other, but shut up like a
clam.

"I think you had better come along with us as a material witness,"
burst out Winters roughly.

Kennedy said nothing, leaving that sort of third degree work to the
detective. But he was not idle, as Winters tried to extract more than
the monosyllables, "I don't know," in answer to every inquiry of Muller
about his employer's life and business.

A low exclamation from Craig attracted my attention from Winters. In a
corner he had discovered a small box and had opened it. Inside was a
dry battery and a most peculiar instrument, something like a little
flat telephone transmitter yet attached by wires to earpieces that
fitted over the head after the manner of those of a wireless detector.

"What's this?" asked Kennedy, dangling it before Muller.

He looked at it phlegmatically. "A deaf instrument I have been working
on," replied the jeweler. "My hearing is getting poor."

Kennedy looked hastily from the instrument to the man.

"I think I'll take it along with us," he said quietly.

Winters, true to his instincts, had been searching Muller in the
meantime. Besides the various assortment that a man carries in his
pockets usually, including pens, pencils, notebooks, a watch, a
handkerchief, a bunch of keys, one of which was large enough to open a
castle, there was a bunch of blank and unissued pawn-tickets bearing
the name, "Stein's One Per Cent. a Month Loans," and an address on the
Bowery.

Was Muller the "fence" we were seeking, or only a tool for the "fence"
higher up? Who was this Stein?

What it all meant I could only guess. It was a far cry from the wealth
of Diamond Lane to a dingy Bowery pawnshop, even though pawnbroking at
one per cent. a month--and more, on the side--pays. I knew, too, that
diamonds are hoarded on the East Side as nowhere else in the world,
outside of India. It was no uncommon thing, I had heard, for a
pawnbroker whose shop seemed dirty and greasy to the casual visitor to
have stored away in his vault gems running into the hundreds of
thousands of dollars.

"Mrs. Moulton must know of this," remarked Kennedy. "Winters, you and
Jameson bring Muller along. I am going up to the Deluxe."

I must say that I was surprised at finding Mrs. Moulton there. Outside
the suite Winters and I waited with the unresisting Muller, while
Kennedy entered. But through the door which he left ajar I could hear
what passed.

"Mrs. Moulton," he began, "something terrible has happened--"

He broke off, and I gathered that her pale face and agitated manner
told him that she knew already.

"Where is Mr. Moulton?" he went on, changing his question.

"Mr. Moulton is at his office," she answered tremulously. "He
telephoned while I was out that he had to work to-night. Oh, Mr.
Kennedy--he knows--he knows. I know it. He has avoided me ever since I
missed the replica from-"

"Sh!" cautioned Craig. He had risen and gone to the door.

"Winters," he whispered, "I want you to go down to Lynn Moulton's
office. Meanwhile Jameson can take care of Muller. I am going over to
that place of Stein's presently. Bring Moulton up there. You will wait
here, Walter, for the present," he nodded.

He returned to the room where I could hear her crying softly.

"Now, Mrs. Moulton," he said gently, "I'm afraid I must trouble you to
go with me. I am going over to a pawnbroker's on the Bowery."

"The Bowery?" she repeated, with a genuinely surprised shudder. "Oh,
no, Mr. Kennedy. Don't ask me to go anywhere to-night. I am--I am in no
condition to go anywhere--to do anything--I--"

"But you must," said Kennedy in a low voice.

"I can't. Oh--have mercy on me. I am terribly upset. You--"

"It is your duty to go, Mrs. Moulton," he repeated.

"I don't understand." she murmured. "A pawnbroker's?"

"Come," urged Kennedy, not harshly but firmly, then, as she held back,
added, playing a trump card, "We must work quickly. In his hands we
found the fragments of a torn dress. When the police--"

She uttered a shriek. A glance had told her, if she had deceived
herself before, that Kennedy knew her secret.

Antoinette Moulton was standing before him, talking rapidly.

"Some one has told Lynn. I know it. There is nothing now that I can
conceal. If you had come half an hour later you would not have found
me. He had written to Mr. Schloss, threatening him that if he did not
leave the country he would shoot him at sight. Mr. Schloss showed me
the letter.

"It had come to this. I must either elope with Schloss, or lose his
aid. The thought of either was unendurable. I hated him--yet was
dependent on him.

"To-night I met him, in his empty apartment, alone. I knew that he had
what was left of his money with him, that everything was packed up. I
went prepared. I would not elope. My plan was no less than to make him
pay the balance on the necklace that he had lost--or to murder him.

"I carried a new pistol in my muff, one which Lynn had just bought. I
don't know how I did it. I was desperate.

"He told me he loved me, that Lynn did not, never had--that Lynn had
married me only to show off his wealth and diamonds, to give him a
social! position--that I was merely a--a piece of property--a dummy.

"He tried to kiss me. It was revolting. I struggled away from him.

"And in the struggle, the revolver fell from my muff and exploded on
the floor.

"At once he was aflame with suspicion.

"'So--it's murder you want!' he shouted. 'Well, murder it shall be!'

"I saw death in his eye as he seized my arm. I was defenseless now. The
old passion came over him. Before he killed--he--would have his way
with me.

"I screamed. With a wild effort I twisted away from him.

"He raised his hand to strike me, I saw his eyes, glassy. Then he sank
back--fell to the floor--dead of apoplexy--dead of his furious emotions.

"I fled.

"And now you have found me."

She had turned, hastily, to leave the room. Kennedy blocked the door.

"Mrs. Moulton," he said firmly, "listen to me. What was the first
question you asked me? 'Can I trust you?' And I told you you could.
This is no time for--for suicide." He shot the word out bluntly. "All
may not be lost. I have sent for your husband. Muller is outside."

"Muller?" she cried. "He made the replica."

"Very well. I am going to clear this thing up. Come. You MUST."

It was all confused to me, the dash in a car to the little pawnbroker's
on the first floor of a five-story tenement, the quick entry into the
place by one of Muller's keys.

Over the safe in back was a framework like that which had covered
Schloss' safe. Kennedy tore it away, regardless of the alarm which it
must have sounded. In a moment he was down before it on his knees.

"This is how Schloss' safe was opened so quickly," he muttered, working
feverishly. "Here is some of their own medicine."

He had placed the peculiar telephone-like transmitter close to the
combination lock and was turning the combination rapidly.

Suddenly he rose, gave the bolts a twist, and the ponderous doors swung
open.

"What is it?" I asked eagerly.

"A burglar's microphone," he answered, hastily looking over the
contents of the safe. "The microphone is now used by burglars for
picking combination locks. When you turn the lock, a slight sound is
made when the proper number comes opposite the working point. It can be
heard sometimes by a sensitive ear, although it is imperceptible to
most persons. But by using a microphone it is an easy matter to hear
the sounds which allow of opening the lock."

He had taken a yellow chamois bag out of the safe and opened it.

Inside sparkled the famous Moulton diamonds. He held them up--in all
their wicked brilliancy. No one spoke.

Then he took another yellow bag, more dirty and worn than the first. As
he opened it, Mrs. Moulton could restrain herself no longer.

"The replica!" she cried. "The replica!"

Without a word, Craig handed the real necklace to her. Then he slipped
the paste jewels into the newer of the bags and restored both it and
the empty one to their places, banged shut the door of the safe, and
replaced the wooden screen.

"Quick!" he said to her, "you have still a minute to get away.
Hurry--anywhere--away--only away!"

The look of gratitude that came over her face, as she understood the
full meaning of it was such as I had never seen before.

"Quick!" he repeated.

It was too late.

"For God's sake, Kennedy," shouted a voice at the street door, "what
are you doing here?"

It was McLear himself. He had come with the Hale patrol, on his mettle
now to take care of the epidemic of robberies.

Before Craig could reply a cab drew up with a rush at the curb and two
men, half fighting, half cursing, catapulted themselves into the shop.

They were Winters and Moulton.

Without a word, taking advantage of the first shock of surprise,
Kennedy had clapped a piece of chemical paper on the foreheads of Mrs.
Moulton, then of Moulton, and on Muller's. Oblivious to the rest of us,
he studied the impressions in the full light of the counter.

Moulton was facing his wife with a scornful curl of the lip.

"I've been told of the paste replica--and I wrote Schloss that I'd
shoot him down like the dog he is, you--you traitress," he hissed.

She drew herself up scornfully.

"And I have been told why you married me--to show off your wicked
jewels and help you in your--"

"You lie!" he cried fiercely. "Muller--some one--open this
safe--whosever it is. If what I have been told is true, there is in it
one new bag containing the necklace. It was stolen from Schloss to whom
you sold my jewels. The other old bag, stolen from me, contains the
paste replica you had made to deceive me."

It was all so confused that I do not know how it happened. I think it
was Muller who opened the safe.

"There is the new yellow bag," cried Moulton, "from Schloss' own safe.
Open it."

McLear had taken it. He did so. There sparkled not the real gems, but
the replica.

"The devil!" Moulton exclaimed, breaking from Winters and seizing the
old bag.

He tore it open and--it was empty.

"One moment," interrupted Kennedy, looking up quietly from the counter.
"Seal that safe again, McLear. In it are the Schloss jewels and the
products of half a dozen other robberies which the dupe Muller--or
Stein, as you please--pulled off, some as a blind to conceal the real
criminal. You may have shown him how to leave no finger prints, but you
yourself have left what is just as good--your own forehead print.
McLear--you were right. There's your criminal--Lynn Moulton,
professional fence, the brains of the thing."



CHAPTER XIX

THE GERM LETTER


Lynn Moulton made no fight and Kennedy did not pursue the case, for,
with the rescue of Antoinette Moulton, his interest ceased.

Blackmail takes various forms, and the Moulton affair was only one
phase of it. It was not long before we had to meet a much stranger
attempt.

"Read the letter, Professor Kennedy. Then I will tell you the sequel."

Mrs. Hunter Blake lay back in the cushions of her invalid chair in the
sun parlor of the great Blake mansion on Riverside Drive, facing the
Hudson with its continuous reel of maritime life framed against the
green-hilled background of the Jersey shore.

Her nurse, Miss Dora Sears, gently smoothed out the pillows and
adjusted them so that the invalid could more easily watch us. Mrs.
Blake, wealthy, known as a philanthropist, was not an old woman, but
had been for years a great sufferer from rheumatism.

I watched Miss Sears eagerly. Full-bosomed, fine of face and figure,
she was something more than a nurse; she was a companion. She had
bright, sparkling black eyes and an expression about her well-cut mouth
which made one want to laugh with her. It seemed to say that the world
was a huge joke and she invited you to enjoy the joke with her.

Kennedy took the letter which Miss Sears proffered him, and as he did
so I could not help noticing her full, plump forearm on which gleamed a
handsome plain gold bracelet. He spread the letter out on a dainty
wicker table in such a way that we both could see it.

We had been summoned over the telephone to the Blake mansion by
Reginald Blake, Mrs. Blake's eldest son. Reginald had been very
reticent over the reason, but had seemed very anxious and insistent
that Kennedy should come immediately.

Craig read quickly and I followed him, fascinated by the letter from
its very opening paragraph.

"Dear Madam," it began. "Having received my diploma as doctor of
medicine and bacteriology at Heidelberg in 1909, I came to the United
States to study a most serious disease which is prevalent in several of
the western mountain states."

So far, I reflected, it looked like an ordinary appeal for aid. The
next words, however, were queer: "I have four hundred persons of wealth
on my list. Your name was--"

Kennedy turned the page. On the next leaf of the letter sheet was
pasted a strip of gelatine. The first page had adhered slightly to the
gelatine.

"Chosen by fate," went on the sentence ominously.

"By opening this letter," I read, "you have liberated millions of the
virulent bacteria of this disease. Without a doubt you are infected by
this time, for no human body is impervious to them, and up to the
present only one in one hundred has fully recovered after going through
all its stages."

I gasped. The gelatine had evidently been arranged so that when the two
sheets were pulled apart, the germs would be thrown into the air about
the person opening the letter. It was a very ingenious device.

The letter continued, "I am happy to say, however, that I have a
prophylactic which will destroy any number of these germs if used up to
the ninth day. It is necessary only that you should place five thousand
dollars in an envelope and leave it for me to be called for at the desk
of the Prince Henry Hotel. When the messenger delivers the money to me,
the prophylactic will be sent immediately.

"First of all, take a match and burn this letter to avoid spreading the
disease. Then change your clothes and burn the old ones. Enclosed you
will find in a germ-proof envelope an exact copy of this letter. The
room should then be thoroughly fumigated. Do not come into close
contact with anyone near and dear to you until you have used the
prophylactic. Tell no one. In case you do, the prophylactic will not be
sent under any circumstances. Very truly yours, DR. HANS HOPF."

"Blackmail!" exclaimed Kennedy, looking intently again at the gelatine
on the second page, as I involuntarily backed away and held my breath.

"Yes, I know," responded Mrs. Blake anxiously, "but is it true?"

There could be no doubt from the tone of her voice that she more than
half believed that it was true.

"I cannot say--yet," replied Craig, still cautiously scanning the
apparently innocent piece of gelatine on the original letter which Mrs.
Blake had not destroyed. "I shall have to keep it and examine it."

On the gelatine I could see a dark mass which evidently was supposed to
contain the germs.

"I opened the letter here in this room," she went on. "At first I
thought nothing of it. But this morning, when Buster, my prize
Pekinese, who had been with me, sitting on my lap at the time, and
closer to the letter even than I was, when Buster was taken suddenly
ill, I--well, I began to worry."

She finished with a little nervous laugh, as people will to hide their
real feelings.

"I should like to see the dog," remarked Kennedy simply.

"Miss Sears," asked her mistress, "will you get Buster, please?"

The nurse left the room. No longer was there the laughing look on her
face. This was serious business.

A few minutes later she reappeared, carrying gingerly a small dog
basket. Mrs. Blake lifted the lid. Inside was a beautiful little
"Peke," and it was easy to see that Buster was indeed ill.

"Who is your doctor?" asked Craig, considering.

"Dr. Rae Wilson, a very well-known woman physician."

Kennedy nodded recognition of the name. "What does she say?" he asked,
observing the dog narrowly.

"We haven't told anyone, outside, of it yet," replied Mrs. Blake. "In
fact until Buster fell sick, I thought it was a hoax."

"You haven't told anyone?"

"Only Reginald and my daughter Betty. Betty is frantic--not with fear
for herself, but with fear for me. No one can reassure her. In fact it
was as much for her sake as anyone's that I sent for you. Reginald has
tried to trace the thing down himself, but has not succeeded."

She paused. The door opened and Reginald Blake entered. He was a young
fellow, self confident and no doubt very efficient at the new dances,
though scarcely fitted to rub elbows with a cold world which, outside
of his own immediate circle, knew not the name of Blake. He stood for a
moment regarding us through the smoke of his cigarette.

"Tell me just what you have done," asked Kennedy of him as his mother
introduced him, although he had done the talking for her over the
telephone.

"Done?" he drawled. "Why, as soon as mother told me of the letter, I
left an envelope up at the Prince Henry, as it directed."

"With the money?" put in Craig quickly.

"Oh, no--just as a decoy."

"Yes. What happened?"

"Well, I waited around a long time. It was far along in the day when a
woman appeared at the desk. I had instructed the clerk to be on the
watch for anyone who asked for mail addressed to a Dr. Hopf. The clerk
slammed the register. That was the signal. I moved up closer."

"What did she look like?" asked Kennedy keenly.

"I couldn't see her face. But she was beautifully dressed, with a long
light flowing linen duster, a veil that hid her features and on her
hands and arms a long pair of motoring doeskin gloves. By George, she
was a winner--in general looks, though. Well, something about the
clerk, I suppose, must have aroused her suspicions. For, a moment
later, she was gone in the crowd. Evidently she had thought of the
danger and had picked out a time when the lobby would be full and
everybody busy. But she did not leave by the front entrance through
which she entered. I concluded that she must have left by one of the
side street carriage doors."

"And she got away?"

"Yes. I found that she asked one of the boys at the door to crank up a
car standing at the curb. She slid into the seat, and was off in a
minute."

Kennedy said nothing. But I knew that he was making a mighty effort to
restrain comment on the bungling amateur detective work of the son of
our client.

Reginald saw the look on his face. "Still," he hastened, "I got the
number of the car. It was 200859 New York."

"You have looked it up?" queried Kennedy quickly.

"I didn't need to do it. A few minutes later Dr. Rae Wilson herself
came out--storming like mad. Her car had been stolen at the very door
of the hotel by this woman with the innocent aid of the hotel
employees."

Kennedy was evidently keenly interested. The mention of the stolen car
had apparently at once suggested an idea to him.

"Mrs. Blake," he said, as he rose to go, "I shall take this letter with
me. Will you see that Buster is sent up to my laboratory immediately?"

She nodded. It was evident that Buster was a great pet with her and
that it was with difficulty she kept from smoothing his silky coat.

"You--you won't hurt Buster?" she pleaded.

"No. Trust me. More than that, if there is any possible way of
untangling this mystery, I shall do it."

Mrs. Blake looked rather than spoke her thanks. As we went downstairs,
accompanied by Miss Sears, we could see in the music room a very
interesting couple, chatting earnestly over the piano.

Betty Blake, a slip of a girl in her first season, was dividing her
attention between her visitor and the door by which we were passing.

She rose as she heard us, leaving the young man standing alone at the
piano. He was of an age perhaps a year or two older than Reginald
Blake. It was evident that, whatever Miss Betty might think, he had
eyes for no one else but the pretty debutante. He even seemed to be
regarding Kennedy sullenly, as if he were a possible rival.

"You--you don't think it is serious?" whispered Betty in an undertone,
scarcely waiting to be introduced. She had evidently known of our
visit, but had been unable to get away to be present upstairs.

"Really, Miss Blake," reassured Kennedy, "I can't say. All I can do is
to repeat what I have already said to your mother. Keep up a good heart
and trust me to work it out."

"Thank you," she murmured, and then, impulsively extending her small
hand to Craig, she added, "Mr. Kennedy, if there is anything I can do
to help you, I beg that you will call on me."

"I shall not forget," he answered, relinquishing the hand reluctantly.
Then, as she thanked him, and turned again to her guest, he added in a
low tone to me, "A remarkable girl, Walter, a girl that can be depended
on."

We followed Miss Sears down the hall.

"Who was that young man in the music room?" asked Kennedy, when we were
out of earshot.

"Duncan Baldwin," she answered. "A friend and bosom companion of
Reginald."

"He seems to think more of Betty than of her brother," Craig remarked
dryly.

Miss Sears smiled. "Sometimes, we think they are secretly engaged," she
returned. We had almost reached the door. "By the way," she asked
anxiously, "do you think there are any precautions that I should take
for Mrs. Blake--and the rest?"

"Hardly," answered Kennedy, after a moment's consideration, "as long as
you have taken none in particular already. Still, I suppose it will do
no harm to be as antiseptic as possible."

"I shall try," she promised, her face showing that she considered the
affair now in a much more serious light than she had before our visit.

"And keep me informed of anything that turns up," added Kennedy handing
her a card with the telephone number of the laboratory.

As we left the Blake mansion, Kennedy remarked, "We must trace that car
somehow--at least we must get someone working on that."

Half an hour later we were in a towering office building on Liberty
Street, the home of various kinds of insurance. Kennedy stopped before
a door which bore the name, "Douglas Garwood: Insurance Adjuster."

Briefly, Craig told the story of the stolen car, omitting the account
of the dastardly method taken to blackmail Mrs. Blake. As he proceeded
a light seemed to break on the face of Garwood, a heavyset man, whose
very gaze was inquisitorial.

"Yes, the theft has been reported to us already by Dr. Wilson herself,"
he interrupted. "The car was insured in a company I represent."

"I had hoped so," remarked Kennedy, "Do you know the woman?" he added,
watching the insurance adjuster who had been listening intently as he
told about the fair motor car thief.

"Know her?" repeated Garwood emphatically. "Why, man, we have been so
close to that woman that I feel almost intimate with her. The
descriptions are those of a lady, well-dressed, and with a voice and
manner that would carry her through any of the fashionable hotels,
perhaps into society itself."

"One of a gang of blackmailers, then," I hazarded.

Garwood shrugged his shoulders. "Perhaps," he acquiesced. "It is
automobile thieving that interests me, though. Why," he went on, rising
excitedly, "the gangs of these thieves are getting away with half a
million dollars' worth of high-priced cars every year. The police seem
to be powerless to stop it. We appeal to them, but with no result. So,
now we have taken things into our own hands."

"What are you doing in this case?" asked Kennedy.

"What the insurance companies have to do to recover stolen
automobiles," Garwood replied. "For, with all deference to your friend,
Deputy O'Connor, it is the insurance companies rather than the police
who get stolen cars back."

He had pulled out a postal card from a pigeon hole in his desk,
selecting it from several apparently similar. We read:

$250.00 REWARD

We will pay $100.00 for car, $150.00 additional for information which
will convict the thief. When last seen, driven by a woman, name not
known, who is described as dark-haired, well-dressed, slight,
apparently thirty years old. The car is a Dixon, 1912, seven-passenger,
touring, No. 193,222, license No. 200,859, New York; dark red body,
mohair top, brass lamps, has no wind shield; rear axle brake band
device has extra nut on turnbuckle not painted. Car last seen near
Prince Henry Hotel, New York City, Friday, the 10th.

Communicate by telegraph or telephone, after notifying nearest police
department, with Douglas Garwood, New York City. "The secret of it is,"
explained Garwood, as we finished reading, "that there are innumerable
people who keep their eyes open and like to earn money easily. Thus we
have several hundreds of amateur and enthusiastic detectives watching
all over the city and country for any car that looks suspicious."

Kennedy thanked him for his courtesy, and we rose to go. "I shall be
glad to keep you informed of anything that turns up," he promised.



CHAPTER XX

THE ARTIFICIAL KIDNEY


In the laboratory, Kennedy quietly set to work. He began by tearing
from the germ letter the piece of gelatine and first examining it with
a pocket lens. Then, with a sterile platinum wire, he picked out
several minute sections of the black spot on the gelatine and placed
them in agar, blood serum, and other media on which they would be
likely to grow.

"I shall have to wait until to-morrow to examine them properly," he
remarked. "There are colonies of something there, all right, but I must
have them more fully developed."

A hurried telephone call late in the day from Miss Sears told us that
Mrs. Blake herself had begun to complain, and that Dr. Wilson had been
summoned but had been unable to give an opinion on the nature of the
malady.

Kennedy quickly decided on making a visit to the doctor, who lived not
far downtown from the laboratory.

Dr. Rae Wilson proved to be a nervous little woman, inclined, I felt,
to be dictatorial. I thought that secretly she felt a little piqued at
our having been taken into the Blakes' confidence before herself, and
Kennedy made every effort to smooth that aspect over tactfully.

"Have you any idea what it can be?" he asked finally.

She shook her head noncommittally. "I have taken blood smears," she
answered, "but so far haven't been able to discover anything. I shall
have to have her under observation for a day or two before I can answer
that. Still, as Mrs. Blake is so ill, I have ordered another trained
nurse to relieve Miss Sears of the added work, a very efficient nurse,
a Miss Rogers."

Kennedy had risen to go. "You have had no word about your car?" he
asked casually.

"None yet. I'm not worrying. It was insured."

"Who is this arch criminal, Dr. Hopf?" I mused as we retraced our steps
to the laboratory. "Is Mrs. Blake stricken now by the same trouble that
seems to have affected Buster?"

"Only my examination will show," he said. "I shall let nothing
interfere with that now. It must be the starting point for any work
that I may do in the case."

We arrived at Kennedy's workshop of scientific crime and he immediately
plunged into work. Looking up he caught sight of me standing helplessly
idle.

"Walter," he remarked thoughtfully adjusting a microscope, "suppose you
run down and see Garwood. Perhaps he has something to report. And by
the way, while you are out, make inquiries about the Blakes, young
Baldwin, Miss Sears and this Dr. Wilson. I have heard of her before, at
least by name. Perhaps you may find something interesting."

Glad to have a chance to seem to be doing something whether it amounted
to anything or not, I dropped in to see Garwood. So far he had nothing
to report except the usual number of false alarms. From his office I
went up to the Star where fortunately I found one of the reporters who
wrote society notes.

The Blakes, I found, as we already knew, to be well known and moving in
the highest social circles. As far as known they had no particular
enemies, other than those common to all people of great wealth. Dr.
Wilson had a large practice, built up in recent years, and was one of
the best known society physicians for women. Miss Sears was unknown, as
far as I could determine. As for Duncan Baldwin, I found that he had
become acquainted with Reginald Blake in college, that he came of no
particular family and seemed to have no great means, although he was
very popular in the best circles. In fact he had had, thanks to his
friend, a rather meteoric rise in society, though it was reported that
he was somewhat involved in debt as a result.

I returned to the laboratory to find that Craig had taken out of a
cabinet a peculiar looking arrangement. It consisted of thirty-two
tubes, each about sixteen inches long, with S-turns, like a minute
radiator. It was altogether not over a cubic foot in size, and enclosed
in a glass cylinder. There were in it, perhaps, fifty feet of tubes, a
perfectly-closed tubular system which I noticed Kennedy was keeping
absolutely sterile in a germicidal solution of some kind.

Inside the tubes and surrounding them was a saline solution which was
kept at a uniform temperature by a special heating apparatus.

Kennedy had placed the apparatus on the laboratory table and then
gently took the little dog from his basket and laid him beside it. A
few minutes later the poor little suffering Buster was mercifully under
the influence of an anesthetic.

Quickly Craig worked. First he attached the end of one of the tubes by
means of a little cannula to the carotid artery of the dog. Then the
other was attached to the jugular vein.

As he released the clamp which held the artery, the little dog's
feverishly beating heart spurted the arterial blood from the carotid
into the tubes holding the normal salt solution and that pressure, in
turn, pumped the salt solution which filled the tubes into the jugular
vein, thus replacing the arterial blood that had poured into the tubes
from the other end and maintaining the normal hydrostatic conditions in
the body circulation. The dog was being kept alive, although perhaps a
third of his blood was out of his body.

"You see," he said at length, after we had watched the process a few
minutes, "what I have here is in reality an artificial kidney. It is a
system that has been devised by several doctors at Johns Hopkins.

"If there is any toxin in the blood of this dog, the kidneys are
naturally endeavoring to eliminate it. Perhaps it is being eliminated
too slowly. In that case this arrangement which I have here will aid
them. We call it vividiffusion and it depends for its action on the
physical principle of osmosis, the passage of substances of a certain
kind through a porous membrane, such as these tubes of celloidin.

"Thus any substance, any poison that is dialyzable is diffused into the
surrounding salt solution and the blood is passed back into the body,
with no air in it, no infection, and without alteration. Clotting is
prevented by the injection of a harmless substance derived from
leeches, known as hirudin. I prevent the loss of anything in the blood
which I want retained by placing in the salt solution around the tubes
an amount of that substance equal to that held in solution by the
blood. Of course that does not apply to the colloidal substances in the
blood which would not pass by osmosis under any circumstances. But by
such adjustments I can remove and study any desired substance in the
blood, provided it is capable of diffusion. In fact this little
apparatus has been found in practice to compare favorably with the
kidneys themselves in removing even a lethal dose of poison."

I watched in amazement. He was actually cleaning the blood of the dog
and putting it back again, purified, into the little body. Far from
being cruel, as perhaps it might seem, it was in reality probably the
only method by which the animal could be saved, and at the same time it
was giving us a clue as to some elusive, subtle substance used in the
case.

"Indeed," Kennedy went on reflectively, "this process can be kept up
for several hours without injury to the dog, though I do not think that
will be necessary to relieve the unwonted strain that has been put upon
his natural organs. Finally, at the close of the operation, serious
loss of blood is overcome by driving back the greater part of it into
his body, closing up the artery and vein, and taking good care of the
animal so that he will make a quick recovery."

For a long time I watched the fascinating process of seeing the life
blood coursing through the porous tubes in the salt solution, while
Kennedy gave his undivided attention to the success of the delicate
experiment. It was late when I left him, still at work over Buster, and
went up to our apartment to turn in, convinced that nothing more would
happen that night.

The next morning, with characteristic energy, Craig was at work early,
examining the cultures he had made from the black spots on the gelatine.

By the look of perplexity on his face, I knew that he had discovered
something that instead of clearing the mystery up, further deepened it.

"What do you find?" I asked anxiously.

"Walter," he exclaimed, laying aside the last of the slides which he
had been staining and looking at intently through the microscope, "that
stuff on the gelatine is entirely harmless. There was nothing in it
except common mold."

For the moment I did not comprehend. "Mold?" I repeated.

"Yes," he replied, "just common, ordinary mold such as grows on the top
of a jar of fruit or preserves when it is exposed to the air."

I stifled an exclamation of incredulity. It seemed impossible that the
deadly germ note should be harmless, in view of the events that had
followed its receipt.

Just then the laboratory door was flung open and Reginald Blake, pale
and excited, entered. He had every mark of having been up all night.

"What's the matter?" asked Craig.

"It's about my mother," he blurted out. "She seems to be getting worse
all the time. Miss Sears is alarmed, and Betty is almost ill herself
with worry. Dr. Wilson doesn't seem to know what it is that affects
her, and neither does the new nurse. Can you DO something?"

There was a tone of appeal in his voice that was not like the
self-sufficient Reginald of the day before.

"Does there seem to be any immediate danger?" asked Kennedy.

"Perhaps not--I can't say," he urged. "But she is gradually getting
worse instead of better."

Kennedy thought a moment. "Has anything else happened?" he asked slowly.

"N-no. That's enough, isn't it?"

"Indeed it is," replied Craig, trying to be reassuring. Then,
recollecting Betty, he added, "Reginald, go back and tell your sister
for me that she must positively make the greatest effort of her life to
control herself. Tell her that her mother needs her--needs her well and
brave. I shall be up at the house immediately. Do the best you can. I
depend on you."

Kennedy's words seemed to have a bracing effect on Reginald and a few
moments later he left, much calmer.

"I hope I have given him something to do which will keep him from
mussing things up again," remarked Kennedy, mindful of Reginald's
former excursion into detective work.

Meanwhile Craig plunged furiously into his study of the substances he
had isolated from the saline solution in which he had "washed" the
blood of the little Pekinese.

"There's no use doing anything in the dark," he explained. "Until we
know what it is we are fighting we can't very well fight."

For the moment I was overwhelmed by the impending tragedy that seemed
to be hanging over Mrs. Blake. The more I thought of it, the more
inexplicable became the discovery of the mold.

"That is all very well about the mold on the gelatine strip in the
letter," I insisted at length. "But, Craig, there must be something
wrong somewhere. Mere molds could not have made Buster so ill, and now
the infection, or whatever it is, has spread to Mrs. Blake herself.
What have you found out by studying Buster?"

He looked up from his close scrutiny of the material in one of the test
tubes which contained something he had recovered from the saline
solution of the diffusion apparatus.

I could read on his face that whatever it was, it was serious. "What is
it?" I repeated almost breathlessly.

"I suppose I might coin a word to describe it," he answered slowly,
measuring his phrases. "Perhaps it might be called
hyper-amino-acidemia."

I puckered my eyes at the mouth-filling term Kennedy smiled. "It would
mean," he explained, "a great quantity of the amino-acids,
non-coagulable, nitrogenous compounds in the blood. You know the
indols, the phenols, and the amins are produced both by putrefactive
bacteria and by the process of metabolism, the burning up of the
tissues in the process of utilizing the energy that means life. But
under normal circumstances, the amins are not present in the blood in
any such quantities as I have discovered by this new method of
diffusion."

He paused a moment, as if in deference to my inability to follow him on
such an abstruse topic, then resumed, "As far as I am able to
determine, this poison or toxin is an amin similar to that secreted by
certain cephalopods found in the neighborhood of Naples. It is an
aromatic amin. Smell it."

I bent over and inhaled the peculiar odor.

"Those creatures," he continued, "catch their prey by this highly
active poison secreted by the so-called salivary glands. Even a little
bit will kill a crab easily."

I was following him now with intense interest, thinking of the
astuteness of a mind capable of thinking of such a poison.

"Indeed, it is surprising," he resumed thoughtfully, "how many an
innocent substance can be changed by bacteria into a virulent poison.
In fact our poisons and our drugs are in many instances the close
relations of harmless compounds that represent the intermediate steps
in the daily process of metabolism."

"Then," I put in, "the toxin was produced by germs, after all?"

"I did not say that," he corrected. "It might have been. But I find no
germs in the blood of Buster. Nor did Dr. Wilson find any in the blood
smears which she took from Mrs. Blake."

He seemed to have thrown the whole thing back again into the limbo of
the unexplainable, and I felt nonplussed.

"The writer of that letter," he went on, waving the piece of sterile
platinum wire with which he had been transferring drops of liquid in
his search for germs, "was a much more skillful bacteriologist than I
thought, evidently. No, the trouble does not seem to be from germs
breathed in, or from germs at all--it is from some kind of germ-free
toxin that has been injected or otherwise introduced."

Vaguely now I began to appreciate the terrible significance of what he
had discovered.

"But the letter?" I persisted mechanically.

"The writer of that was quite as shrewd a psychologist as
bacteriologist," pursued Craig impressively. "He calculated the moral
effect of the letter, then of Buster's illness, and finally of reaching
Mrs. Blake herself."

"You think Dr. Rae Wilson knows nothing of it yet?" I queried.

Kennedy appeared to consider his answer carefully. Then he said slowly:
"Almost any doctor with a microscope and the faintest trace of a
scientific education could recognize disease germs either naturally or
feloniously implanted. But when it comes to the detection of
concentrated, filtered, germ-free toxins, almost any scientist might be
baffled. Walter," he concluded, "this is not mere blackmail, although
perhaps the visit of that woman to the Prince Henry--a desperate thing
in itself, although she did get away by her quick thinking--perhaps
that shows that these people are ready to stop at nothing. No, it goes
deeper than blackmail."

I stood aghast at the discovery of this new method of scientific
murder. The astute criminal, whoever he might be, had planned to leave
not even the slender clue that might be afforded by disease germs. He
was operating, not with disease itself, but with something showing the
ultimate effects, perhaps, of disease with none of the preliminary
symptoms, baffling even to the best of physicians.

I scarcely knew what to say. Before I realized it, however, Craig was
at last ready for the promised visit to Mrs. Blake. We went together,
carrying Buster, in his basket, not recovered, to be sure, but a very
different little animal from the dying creature that had been sent to
us at the laboratory.



CHAPTER XXI

THE POISON BRACELET


We reached the Blake mansion and were promptly admitted. Miss Betty,
bearing up bravely under Reginald's reassurances, greeted us before we
were fairly inside the door, though she and her brother were not able
to conceal the fact that their mother was no better. Miss Sears was
out, for an airing, and the new nurse, Miss Rogers, was in charge of
the patient.

"How do you feel, this morning?" inquired Kennedy as we entered the
sun-parlor, where Mrs. Blake had first received us.

A single glance was enough to satisfy me of the seriousness of her
condition. She seemed to be in almost a stupor from which she roused
herself only with difficulty. It was as if some overpowering toxin were
gradually undermining her already weakened constitution.

She nodded recognition, but nothing further.

Kennedy had set the dog basket down near her wheel-chair and she caught
sight of it.

"Buster?" she murmured, raising her eyes. "Is--he--all right?"

For answer, Craig simply raised the lid of the basket. Buster already
seemed to have recognized the voice of his mistress, and, with an
almost human instinct, to realize that though he himself was still weak
and ill, she needed encouragement.

As Mrs. Blake stretched out her slender hand, drawn with pain, to his
silky head, he gave a little yelp of delight and his little red tongue
eagerly caressed her hand.

It was as though the two understood each other. Although Mrs. Blake, as
yet, had no more idea what had happened to her pet, she seemed to feel
by some subtle means of thought transference that the intelligent
little animal was conveying to her a message of hope. The caress, the
sharp, joyous yelp, and the happy wagging of the bushy tail seemed to
brighten her up, at least for the moment, almost as if she had received
a new impetus.

"Buster!" she exclaimed, overjoyed to get her pet back again in so much
improved condition.

"I wouldn't exert myself too much, Mrs. Blake," cautioned Kennedy.

"Were--were there any germs in the letter?" she asked, as Reginald and
Betty stood on the other side of the chair, much encouraged,
apparently, at this show of throwing off the lethargy that had seized
her.

"Yes, but about as harmless as those would be on a piece of cheese,"
Kennedy hastened. "But I--I feel so weak, so played out--and my head--"

Her voice trailed off, a too evident reminder that her improvement had
been only momentary and prompted by the excitement of our arrival.

Betty bent down solicitously and made her more comfortable as only one
woman can make another. Kennedy, meanwhile, had been talking to Miss
Rogers, and I could see that he was secretly taking her measure.

"Has Dr. Wilson been here this morning?" I heard him ask.

"Not yet," she replied. "But we expect her soon."

"Professor Kennedy?" announced a servant.

"Yes?" answered Craig.

"There is someone on the telephone who wants to speak to you. He said
he had called the laboratory first and that they told him to call you
here."

Kennedy hurried after the servant, while Betty and Reginald joined me,
waiting, for we seemed to feel that something was about to happen.

"One of the unofficial detectives has unearthed a clue," he whispered
to me a few moments later when he returned. "It was Garwood." Then to
the others he added, "A car, repainted, and with the number changed,
but otherwise answering the description of Dr. Wilson's has been traced
to the West Side. It is somewhere in the neighborhood of a saloon and
garage where drivers of taxicabs hang out. Reginald, I wish you would
come along with us."

To Betty's unspoken question Craig hastened to add, "I don't think
there is any immediate danger. If there is any change--let me know. I
shall call up soon. And meanwhile," he lowered his voice to impress the
instruction on her, "don't leave your mother for a moment--not for a
moment," he emphasized.

Reginald was ready and together we three set off to meet Garwood at a
subway station near the point where the car had been reported. We had
scarcely closed the front door, when we ran into Duncan Baldwin, coming
down the street, evidently bent on inquiring how Mrs. Blake and Betty
were.

"Much better," reassured Kennedy. "Come on, Baldwin. We can't have too
many on whom we can rely on an expedition like this."

"Like what?" he asked, evidently not comprehending.

"There's a clue, they think, to that car of Dr. Wilson's," hastily
explained Reginald, linking his arm into that of his friend and falling
in behind us, as Craig hurried ahead.

It did not take long to reach the subway, and as we waited for the
train, Craig remarked: "This is a pretty good example of how the
automobile is becoming one of the most dangerous of criminal weapons.
All one has to do nowadays, apparently, after committing a crime, is to
jump into a waiting car and breeze away, safe."

We met Garwood and under his guidance picked our way westward from the
better known streets in the heart of the city, to a section that was
anything but prepossessing.

The place which Garwood sought was a typical Raines Law hotel on a
corner, with a saloon on the first floor, and apparently the requisite
number of rooms above to give it a legal license.

We had separated a little so that we would not attract undue attention.
Kennedy and I entered the swinging doors boldly, while the others
continued across to the other corner to wait with Garwood and take in
the situation. It was a strange expedition and Reginald was fidgeting
while Duncan seemed nervous.

Among the group of chauffeurs lounging at the bar and in the back room
anyone who had ever had any dealings with the gangs of New York might
have recognized the faces of men whose pictures were in the rogues'
gallery and who were members of those various aristocratic
organizations of the underworld.

Kennedy glanced about at the motley crowd. "This is a place where you
need only to be introduced properly," he whispered to me, "to have any
kind of crime committed for you."

As we stood there, observing, without appearing to do so, through an
open window on the side street I could tell from the sounds that there
was a garage in the rear of the hotel.

We were startled to hear a sudden uproar from the street.

Garwood, impatient at our delay, had walked down past the garage to
reconnoiter. A car was being backed out hurriedly, and as it turned and
swung around the corner, his trained eye had recognized it.

Instantly he had reasoned that it was an attempt to make a getaway, and
had raised an alarm.

Those nearest the door piled out, keen for any excitement. We, too,
dashed out on the street. There we saw passing an automobile, swaying
and lurching at the terrific speed with which its driver, urged it up
the avenue. As he flashed by he looked like an Italian to me, perhaps a
gunman.

Garwood had impressed a passing trolley car into service and was
pursuing the automobile in it, as it swayed on its tracks as crazily as
the motor did on the roadway, running with all the power the motorman
could apply.

A mounted policeman galloped past us, blazing away at the tires. The
avenue was stirred, as seldom even in its strenuous life, with reports
of shots, honking of horns, the clang of trolley bells and the shouts
of men.

The pursuers were losing when there came a rattle and roar from the
rear wheels which told that the tires were punctured and the heavy car
was riding on its rims. A huge brewery wagon crossing a side street
paused to see the fun, effectually blocking the road.

The car jolted to a stop. The chauffeur leaped out and a moment later
dived down into a cellar. In that congested district, pursuit was
useless.

"Only an accomplice," commented Kennedy. "Perhaps we can get him some
other way if we can catch the man--or woman--higher up."

Down the street now we could see Garwood surrounded by a curious crowd
but in possession of the car. I looked about for Duncan and Reginald.
They had apparently been swallowed up in the crowds of idlers which
seemed to be pouring out of nowhere, collecting to gape at the
excitement, after the manner of a New York crowd.

As I ran my eye over them, I caught sight of Reginald near the corner
where we had left him in an incipient fight with someone who had a
fancied grievance. A moment later we had rescued him.

"Where's Duncan?" he panted. "Did anything happen to him? Garwood told
us to stay here--but we got separated."

Policemen had appeared on the heels of the crowd and now, except for a
knot following Garwood, things seemed to be calming down.

The excitement over, and the people thinning out, Kennedy still could
not find any trace of Duncan. Finally he glanced in again through the
swinging doors. There was Duncan, evidently quite upset by what had
occurred, fortifying himself at the bar.

Suddenly from above came a heavy thud, as if someone had fallen on the
floor above us, followed by a suppressed shuffling of feet and a cry of
help.

Kennedy sprang toward a side door which led out into the hall to the
hotel room above. It was locked. Before any of the others he ran out on
the street and into the hall that way, taking the stairs two at a time,
past a little cubby-hole of an "office" and down the upper hall to a
door from which came the cry.

It was a peculiar room into which we burst, half bedroom, half
workshop, or rather laboratory, for on a deal table by a window stood a
rack of test-tubes, several beakers, and other paraphernalia.

A chambermaid was shrieking over a woman who was lying lethargic on the
floor.

I looked more closely.

It was Dora Sears.

For the moment I could not imagine what had happened. Had the events of
the past few days worked on her mind and driven her into temporary
insanity? Or had the blackmailing gang of automobile thieves, failing
in extorting money by their original plan, seized her?

Kennedy bent over and tried to lift her up. As he did so, the gold
bracelet, unclasped, clattered to the floor.

He picked it up and for a moment looked at it. It was hollow, but in
that part of it where it unclasped could be seen a minute hypodermic
needle and traces of a liquid.

"A poison bracelet," he muttered to himself, "one in which enough of a
virulent poison could be hidden so that in an emergency death could
cheat the law."

"But this Dr. Hopf," exclaimed Reginald, who stood behind us looking
from the insensible girl to the bracelet and slowly comprehending what
it all meant, "she alone knows where and who he is!"

We looked at Kennedy. What was to be done? Was the criminal higher up
to escape because one of his tools had been cornered and had taken the
easiest way to get out?

Kennedy had taken down the receiver of the wall telephone in the room.
A moment later he was calling insistently for his laboratory. One of
the students in another part of the building answered. Quickly he
described the apparatus for vividiffusion and how to handle it without
rupturing any of the delicate tubes.

"The large one," he ordered, "with one hundred and ninety-two tubes.
And hurry."

Before the student appeared, came an ambulance which some one in the
excitement had summoned. Kennedy quickly commandeered both the young
doctor and what surgical material he had with him.

Briefly he explained what he proposed to do and before the student
arrived with the apparatus, they had placed the nurse in such a
position that they were ready for the operation.

The next room which was unoccupied had been thrown open to us and there
I waited with Reginald and Duncan, endeavoring to explain to them the
mysteries of the new process of washing the blood.

The minutes lengthened into hours, as the blood of the poisoned girl
coursed through its artificial channel, literally being washed of the
toxin from the poisoned bracelet.

Would it succeed? It had saved the life of Buster. But would it bring
back the unfortunate before us, long enough even for her to yield her
secret and enable us to catch the real criminal. What if she died?

As Kennedy worked, the young men with me became more and more
fascinated, watching him. The vividiffusion apparatus was now in full
operation.

In the intervals when he left the apparatus in charge of the young
ambulance surgeon Kennedy was looking over the room. In a trunk which
was open he found several bundles of papers. As he ran his eye over
them quickly, he selected some and stuffed them into his pocket, then
went back to watch the working of the apparatus.

Reginald, who had been growing more and more nervous, at last asked if
he might call up Betty to find out how his mother was.

He came back from the telephone, his face wrinkled.

"Poor mother," he remarked anxiously, "do you think she will pull
through, Professor? Betty says that Dr. Wilson has given her no idea
yet about the nature of the trouble."

Kennedy thought a moment. "Of course," he said, "your mother has had no
such relative amount of the poison as Buster has had. I think that
undoubtedly she will recover by purely natural means. I hope so. But if
not, here is the apparatus," and he patted the vividiffusion tubes in
their glass case, "that will save her, too."

As well as I could I explained to Reginald the nature of the toxin that
Kennedy had discovered. Duncan listened, putting in a question now and
then. But it was evident that his thoughts were on something else, and
now and then Reginald, breaking into his old humor, rallied him about
thinking of Betty.

A low exclamation from both Kennedy and the surgeon attracted us.

Dora Sears had moved.

The operation of the apparatus was stopped, the artery and vein had
been joined up, and she was slowly coming out from under the effects of
the anesthetic.

As we gathered about her, at a little distance, we heard her cry in her
delirium, "I--I would have--done--anything--for him."

We strained our ears. Was she talking of the blackmailer, Dr. Hopf?

"Who?" asked Craig, bending over close to her ear.

"I--I would--have done anything," she repeated as if someone had
contradicted her. She went on, dreamily, ramblingly, "He--is--is--my
brother. I--"

She stopped through weakness.

"Where is Dr. Hopf?" asked Kennedy, trying to recall her fleeting
attention.

"Dr. Hopf? Dr. Hopf?" she repeated, then smiling to herself as people
will when they are leaving the borderline of anesthesia, she repeated
the name, "Hopf?"

"Yes," persisted Kennedy.

"There is no Dr. Hopf," she added. "Tell me--did--did they--"

"No Dr. Hopf?" Kennedy insisted.

She had lapsed again into half insensibility.

He rose and faced us, speaking rapidly.

"New York seems to have a mysterious and uncanny attraction for odds
and ends of humanity, among them the great army of adventuresses. In
fact there often seems to be something decidedly adventurous about the
nursing profession. This is a girl of unusual education in medicine.
Evidently she has traveled--her letters show it. Many of them show that
she has been in Italy. Perhaps it was there that she heard of the drug
that has been used in this case. It was she who injected the germ-free
toxin, first into the dog, then into Mrs. Blake, she who wrote the
blackmail letter which was to have explained the death."

He paused. Evidently she had heard dimly, was straining every effort to
hear. In her effort she caught sight of our faces.

Suddenly, as if she had seen an apparition, she raised herself with
almost superhuman strength.

"Duncan!" she cried. "Duncan! Why--didn't you--get away--while there
was time--after you warned me?"

Kennedy had wheeled about and was facing us. He was holding in his hand
some of the letters he had taken from the trunk. Among others was a
folded piece of parchment that looked like a diploma. He unfolded it
and we bent over to read.

It was a diploma from the Central Western College of Nursing. As I read
the name written in, it was with a shock. It was not Dora Sears, but
Dora Baldwin.

"A very clever plot," he ground out, taking a step nearer us. "With the
aid of your sister and a disreputable gang of chauffeurs you planned to
hasten the death of Mrs. Blake, to hasten the inheritance of the Blake
fortune by your future wife. I think your creditors will have less
chance of collecting now than ever, Duncan Baldwin."



CHAPTER XXII

THE DEVIL WORSHIPERS


Tragic though the end of the young nurse, Dora Baldwin, had been, the
scheme of her brother, in which she had become fatally involved, was by
no means as diabolical as that in the case that confronted us a short
time after that.

I recall this case particularly not only because it was so weird but
also because of the unique manner in which it began.

"I am damned--Professor Kennedy--damned!"

The words rang out as the cry of a lost soul. A terrible look of
inexpressible anguish and fear was written on the face of Craig's
visitor, as she uttered them and sank back, trembling, in the easy
chair, mentally and physically convulsed.

As nearly as I had been able to follow, Mrs. Veda Blair's story had
dealt mostly with a Professor and Madame Rapport and something she
called the "Red Lodge" of the "Temple of the Occult."

She was not exactly a young woman, although she was a very attractive
one. She was of an age that is, perhaps, even more interesting than
youth.

Veda Blair, I knew, had been, before her recent marriage to Seward
Blair, a Treacy, of an old, though somewhat unfortunate, family. Both
the Blairs and the Treacys had been intimate and old Seward Blair, when
he died about a year before, had left his fortune to his son on the
condition that he marry Veda Treacy.

"Sometimes," faltered Mrs. Blair, "it is as though I had two souls. One
of them is dispossessed of its body and the use of its organs and is
frantic at the sight of the other that has crept in."

She ended her rambling story, sobbing the terrible words, "Oh--I have
committed the unpardonable sin--I am anathema--I am damned--damned!"

She said nothing of what terrible thing she had done and Kennedy, for
the present, did not try to lead the conversation. But of all the
stories that I have heard poured forth in the confessional of the
detective's office, hers, I think, was the wildest.

Was she insane? At least I felt that she was sincere. Still, I wondered
what sort of hallucination Craig had to deal with, as Veda Blair
repeated the incoherent tale of her spiritual vagaries.

Almost, I had begun to fancy that this was a case for a doctor, not for
a detective, when suddenly she asked a most peculiar question.

"Can people affect you for good or evil, merely by thinking about you?"
she queried. Then a shudder passed over her. "They may be thinking
about me now!" she murmured in terror.

Her fear was so real and her physical distress so evident that Kennedy,
who had been listening silently for the most part, rose and hastened to
reassure her.

"Not unless you make your own fears affect yourself and so play into
their hands," he said earnestly.

Veda looked at him a moment, then shook her head mournfully. "I have
seen Dr. Vaughn," she said slowly.

Dr. Gilbert Vaughn, I recollected, was a well-known alienist in the
city.

"He tried to tell me the same thing," she resumed doubtfully.
"But--oh--I know what I know! I have felt the death thought--and he
knows it!"

"What do you mean?" inquired Kennedy, leaning forward keenly.

"The death thought," she repeated, "a malicious psychic attack. Some
one is driving me to death by it. I thought I could fight it off. I
went away to escape it. Now I have come back--and I have not escaped.
There is always that disturbing influence--always--directed against me.
I know it will--kill me!"

I listened, startled. The death thought! What did it mean? What
terrible power was it? Was it hypnotism? What was this fearsome, cruel
belief, this modern witchcraft that could unnerve a rich and educated
woman? Surely, after all, I felt that this was not a case for a doctor
alone; it called for a detective.

"You see," she went on, heroically trying to control herself, "I have
always been interested in the mysterious, the strange, the occult. In
fact my father and my husband's father met through their common
interest. So, you see, I come naturally by it.

"Not long ago I heard of Professor and Madame Rapport and their new
Temple of the Occult. I went to it, and later Seward became interested,
too. We have been taken into a sort of inner circle," she continued
fearfully, as though there were some evil power in the very words
themselves, "the Red Lodge."

"You have told Dr. Vaughn?" shot out Kennedy suddenly, his eyes fixed
on her face to see what it would betray.

Veda leaned forward, as if to tell a secret, then whispered in a low
voice, "He knows. Like us--he--he is a--Devil Worshiper!"

"What?" exclaimed Kennedy in wide-eyed astonishment.

"A Devil Worshiper," she repeated. "You haven't heard of the Red Lodge?"

Kennedy nodded negatively. "Could you get us--initiated?" he hazarded.

"P--perhaps," she hesitated, in a half-frightened tone. "I--I'll try to
get you in to-night."

She had risen, half dazed, as if her own temerity overwhelmed her.

"You--poor girl," blurted out Kennedy, his sympathies getting the upper
hand for the moment as he took the hand she extended mutely. "Trust me.
I will do all in my power, all in the power of modern science to help
you fight off this--influence."

There must have been something magnetic, hypnotic in his eye.

"I will stop here for you," she murmured, as she almost fled from the
room.

Personally, I cannot say that I liked the idea of spying. It is not
usually clean and wholesome. But I realized that occasionally it was
necessary.

"We are in for it now," remarked Kennedy half humorously, half
seriously, "to see the Devil in the twentieth century."

"And I," I added, "I am, I suppose, to be the reporter to Satan."

We said nothing more about it, but I thought much about it, and the
more I thought, the more incomprehensible the thing seemed. I had heard
of Devil Worship, but had always associated it with far-off Indian and
other heathen lands--in fact never among Caucasians in modern times,
except possibly in Paris. Was there such a cult here in my own city? I
felt skeptical.

That night, however, promptly at the appointed time, a cab called for
us, and in it was Veda Blair, nervous but determined.

"Seward has gone ahead," she explained. "I told him that a friend had
introduced you, that you had studied the occult abroad. I trust you to
carry it out."

Kennedy reassured her.

The curtains were drawn and we could see nothing outside, though we
must have been driven several miles, far out into the suburbs.

At last the cab stopped. As we left it we could see nothing of the
building, for the cab had entered a closed courtyard.

"Who enters the Red Lodge?" challenged a sepulchral voice at the
porte-cochere. "Give the password!"

"The Serpent's Tooth," Veda answered.

"Who are these?" asked the voice.

"Neophytes," she replied, and a whispered parley followed.

"Then enter!" announced the voice at length.

It was a large room into which we were first ushered, to be inducted
into the rites of Satan.

There seemed to be both men and women, perhaps half a dozen votaries.
Seward Blair was already present. As I met him, I did not like the look
in his eye; it was too stary. Dr. Vaughn was there, too, talking in a
low tone to Madame Rapport. He shot a quick look at us. His were not
eyes but gimlets that tried to bore into your very soul. Chatting with
Seward Blair was a Mrs. Langhorne, a very beautiful woman. To-night she
seemed to be unnaturally excited.

All seemed to be on most intimate terms, and, as we waited a few
minutes, I could not help recalling a sentence from Huysmans: "The
worship of the Devil is no more insane than the worship of God. The
worshipers of Satan are mystics--mystics of an unclean sort, it is
true, but mystics none the less."

I did not agree with it, and did not repeat it, of course, but a moment
later I overheard Dr. Vaughn saying to Kennedy: "Hoffman brought the
Devil into modern life. Poe forgoes the aid of demons and works
patiently and precisely by the scientific method. But the result is the
same."

"Yes," agreed Kennedy for the sake of appearances, "in a sense, I
suppose, we are all devil worshipers in modern society--always have
been. It is fear that rules and we fear the bad--not the good."

As we waited, I felt, more and more, the sense of the mysterious, the
secret, the unknown which have always exercised a powerful attraction
on the human mind. Even the aeroplane and the submarine, the X-ray and
wireless have not banished the occult.

In it, I felt, there was fascination for the frivolous and deep appeal
to the intellectual and spiritual. The Temple of the Occult had
evidently been designed to appeal to both types. I wondered how, like
Lucifer, it had fallen. The prime requisite, I could guess already,
however, was--money. Was it in its worship of the root of all evil that
it had fallen?

We passed soon into another room, hung entirely in red, with weird,
cabalistic signs all about, on the walls. It was uncanny, creepy.

A huge reproduction in plaster of one of the most sardonic of Notre
Dame's gargoyles seemed to preside over everything--a terrible figure
in such an atmosphere.

As we entered, we were struck by the blinding glare of the light, in
contrast with the darkened room in which we had passed our brief
novitiate, if it might be called such.

Suddenly the lights were extinguished.

The great gargoyle shone with an infernal light of its own!

"Phosphorescent paint," whispered Kennedy to me.

Still, it did not detract from the weird effect to know what caused it.

There was a startling noise in the general hush.

"Sata!" cried one of the devotees.

A door opened and there appeared the veritable priest of the
Devil--pale of face, nose sharp, mouth bitter, eyes glassy.

"That is Rapport," Vaughn whispered to me.

The worshipers crowded forward.

Without a word, he raised his long, lean forefinger and began to single
them out impressively. As he did so, each spoke, as if imploring aid.

He came to Mrs. Langhorne.

"I have tried the charm," she cried earnestly, "and the one whom I love
still hates me, while the one I hate loves me!"

"Concentrate!" replied the priest, "concentrate! Think always 'I love
him. He must love me. I want him to love me. I love him. He must love
me.' Over and over again you must think it. Then the other side, 'I
hate him. He must leave me. I want him to leave me. I hate him--hate
him.'"

Around the circle he went.

At last his lean finger was outstretched at Veda. It seemed as if some
imp of the perverse were compelling her unwilling tongue to unlock its
secrets.

"Sometimes," she cried in a low, tremulous voice, "something seems to
seize me, as if by the hand and urge me onward. I cannot flee from it."

"Defend yourself!" answered the priest subtly. "When you know that some
one is trying to kill you mentally, defend yourself! Work against it by
every means in your power. Discourage! Intimidate! Destroy!"

I marveled at these cryptic utterances. They shadowed a modern Black
Art, of which I had had no conception--a recrudescence in other
language of the age-old dualism of good and evil. It was a sort of
mental malpractice.

"Over and over again," he went on speaking to her, "the same thought is
to be repeated against an enemy. 'You know you are going to die! You
know you are going to die!' Do it an hour, two hours, at a time. Others
can help you, all thinking in unison the same thought."

What was this, I asked myself breathlessly--a new transcendental
toxicology?

Slowly, a strange mephitic vapor seemed to exhale into the room--or was
it my heightened imagination?



CHAPTER XXIII

THE PSYCHIC CURSE


There came a sudden noise--nameless--striking terror, low, rattling. I
stood rooted to the spot. What was it that held me? Was it an atavistic
joy in the horrible or was it merely a blasphemous curiosity?

I scarcely dared to look.

At last I raised my eyes. There was a live snake, upraised, his fangs
striking out viciously--a rattler!

I would have drawn back and fled, but Craig caught my arm.

"Caged," he whispered monosyllabically.

I shuddered. This, at least, was no drawing-room diablerie.

"It is Ophis," intoned Rapport, "the Serpent--the one active form in
Nature that cannot be ungraceful!"

The appearance of the basilisk seemed to heighten the tension.

At last it broke loose and then followed the most terrible blasphemies.
The disciples, now all frenzied, surrounded closer the priest, the
gargoyle and the serpent.

They worshiped with howls and obscenities. Mad laughter mingled with
pale fear and wild scorn in turns were written on the hectic faces
about me.

They had risen--it became a dance, a reel.

The votaries seemed to spin about on their axes, as it were, uttering a
low, moaning chant as they whirled. It was a mania, the spirit of
demonism. Something unseen seemed to urge them on.

Disgusted and stifled at the surcharged atmosphere, I would have tried
to leave, but I seemed frozen to the spot. I could think of nothing
except Poe's Masque of the Red Death.

Above all the rest whirled Seward Blair himself. The laugh of the
fiend, for the moment, was in his mouth. An instant he stood--the
oracle of the Demon--devil-possessed. Around whirled the frantic
devotees, howling.

Shrilly he cried, "The Devil is in me!"

Forward staggered the devil dancer--tall, haggard, with deep sunken
eyes and matted hair, face now smeared with dirt and blood-red with the
reflection of the strange, unearthly phosphorescence.

He reeled slowly through the crowd, crooning a quatrain, in a low,
monotonous voice, his eyelids drooping and his head forward on his
breast:

 If the Red Slayer think he slays,
   Or the slain think he is slain,
  They know not well the subtle ways
   I keep and pass and turn again!

Entranced the whirling crowd paused and watched. One of their number
had received the "power."

He was swaying slowly to and fro.

"Look!" whispered Kennedy.

His fingers twitched, his head wagged uncannily. Perspiration seemed to
ooze from every pore. His breast heaved.

He gave a sudden yell--ear-piercing. Then followed a screech of hellish
laughter.

The dance had ended, the dancers spellbound at the sight.

He was whirling slowly, eyes protruding now, mouth foaming, chest
rising and falling like a bellows, muscles quivering.

Cries, vows, imprecations, prayers, all blended in an infernal hubbub.

With a burst of ghastly, guttural laughter, he shrieked, "I AM the
Devil!"

His arms waved--cutting, sawing, hacking the air.

The votaries, trembling, scarcely moved, breathed, as he danced.

Suddenly he gave a great leap into the air--then fell, motionless. They
crowded around him. The fiendish look was gone--the demoniac laughter
stilled.

It was over.

The tension of the orgy had been too much for us. We parted, with
scarcely a word, and yet I could feel that among the rest there was a
sort of unholy companionship.

Silently, Kennedy and I drove away in the darkened cab, this time with
Seward and Veda Blair and Mrs. Langhorne.

For several minutes not a word was said. I was, however, much occupied
in watching the two women. It was not because of anything they said or
did. That was not necessary. But I felt that there was a feud,
something that set them against each other.

"How would Rapport use the death thought, I wonder?" asked Craig
speculatively, breaking the silence.

Blair answered quickly. "Suppose some one tried to break away, to
renounce the Lodge, expose its secrets. They would treat him so as to
make him harmless--perhaps insane, confused, afraid to talk, paralyzed,
or even to commit suicide or be killed in an accident. They would put
the death thought on him!"

Even in the prosaic jolting of the cab, away from the terrible
mysteries of the Red Lodge, one could feel the spell.

The cab stopped. Seward was on his feet in a moment and handing Mrs.
Langhorne out at her home. For a moment they paused on the steps for an
exchange of words.

In that moment I caught flitting over the face of Veda a look of
hatred, more intense, more real, more awful than any that had been
induced under the mysteries of the rites at the Lodge.

It was gone in an instant, and as Seward rejoined us I felt that, with
Mrs. Langhorne gone, there was less restraint. I wondered whether it
was she who had inspired the fear in Veda.

Although it was more comfortable, the rest of our journey was made in
silence and the Blairs dropped us at our apartment with many
expressions of cordiality as we left them to proceed to their own.

"Of one thing I'm sure," I remarked, entering the room where only a few
short hours before Mrs. Blair had related her strange tale. "Whatever
the cause of it, the devil dancers don't sham."

Kennedy did not reply. He was apparently wrapped up in the
consideration of the remarkable events of the evening.

As for myself, it was a state of affairs which, the day before, I
should have pronounced utterly beyond the wildest bounds of the
imagination of the most colorful writer. Yet here it was; I had seen it.

I glanced up to find Kennedy standing by the light examining something
he had apparently picked up at the Red Lodge. I bent over to look at
it, too. It was a little glass tube.

"An ampoule, I believe the technical name of such a container is," he
remarked, holding it closer to the light.

In it were the remains of a dried yellow substance, broken up minutely,
resembling crystals.

"Who dropped it?" I asked.

"Vaughn, I think," he replied. "At least, I saw him near Blair,
stooping over him, at the end, and I imagine this is what I saw
gleaming for an instant in the light."

Kennedy said nothing more, and for my part I was thoroughly at sea and
could make nothing out of it all.

"What object can such a man as Dr. Vaughn possibly have in frequenting
such a place?" I asked at length, adding, "And there's that Mrs.
Langhorne--she was interesting, too."

Kennedy made no direct reply. "I shall have them shadowed to-morrow,"
he said briefly, "while I am at work in the laboratory over this
ampoule."

As usual, also, Craig had begun on his scientific studies long before I
was able to shake myself loose from the nightmares that haunted me
after our weird experience of the evening.

He had already given the order to an agency for the shadowing, and his
next move was to start me out, also, looking into the history of those
concerned in the case. As far as I was able to determine, Dr. Vaughn
had an excellent reputation, and I could find no reason whatever for
his connection with anything of the nature of the Red Lodge. The
Rapports seemed to be nearly unknown in New York, although it was
reported that they had come from Paris lately. Mrs. Langhorne was a
divorcee from one of the western states, but little was known about
her, except that she always seemed to be well supplied with money. It
seemed to be well known in the circle in which Seward Blair moved that
he was friendly with her, and I had about reached the conclusion that
she was unscrupulously making use of his friendship, perhaps was not
above such a thing as blackmail.

Thus the day passed, and we heard no word from Veda Blair, although
that was explained by the shadows, whose trails crossed in a most
unexpected manner. Their reports showed that there was a meeting at the
Red Lodge during the late afternoon, at which all had been present
except Dr. Vaughn. We learned also from them the exact location of the
Lodge, in an old house just across the line in Westchester.

It was evidently a long and troublesome analysis that Craig was engaged
in at the laboratory, for it was some hours after dinner that night
when he came into the apartment, and even then he said nothing, but
buried himself in some of the technical works with which his library
was stocked. He said little, but I gathered that he was in great doubt
about something, perhaps, as much as anything, about how to proceed
with so peculiar a case.

It was growing late, and Kennedy was still steeped in his books, when
the door of the apartment, which we happened to have left unlocked, was
suddenly thrown open and Seward Blair burst in on us, wildly excited.

"Veda is gone!" he cried, before either of us could ask him what was
the matter.

"Gone?" repeated Kennedy. "How--where?"

"I don't know," Blair blurted out breathlessly. "We had been out
together this afternoon, and I returned with her. Then I went out to
the club after dinner for a while, and when I got back I missed
her--not quarter of an hour ago. I burst into her room--and there I
found this note. Read it. I don't know what to do. No one seems to know
what has become of her. I've called up all over and then thought
perhaps you might help me, might know some friend of hers that I don't
know, with whom she might have gone out."

Blair was plainly eager for us to help him. Kennedy took the paper from
him. On it, in a trembling hand, were scrawled some words, evidently
addressed to Blair himself:

"You would forgive me and pity me if you knew what I have been through.

"When I refused to yield my will to the will of the Lodge I suppose I
aroused the enmity of the Lodge.

"To-night as I lay in bed, alone, I felt that my hour had come, that
mental forces that were almost irresistible were being directed against
me.

"I realized that I must fight not only for my sanity but for my life.

"For hours I have fought that fight.

"But during those hours, some one, I won't say who, seemed to have
developed such psychic faculties of penetration that they were able to
make their bodies pass through the walls of my room.

"At last I am conquered. I pray that you--"

The writing broke off abruptly, as if she had left it in wild flight.

"What does that mean?" asked Kennedy, "the 'will of the Lodge'?"

Blair looked at us keenly. I fancied that there was even something
accusatory in the look. "Perhaps it was some mental reservation on her
part," he suggested. "You do not know yourself of any reason why she
should fear anything, do you?" he asked pointedly.

Kennedy did not betray even by the motion of an eyelash that we knew
more than we should ostensibly.

There was a tap at the door. I sprang to open it, thinking perhaps,
after all, it was Veda herself.

Instead, a man, a stranger, stood there.

"Is this Professor Kennedy?" he asked, touching his hat.

Craig nodded.

"I am from the psychopathic ward of the City Hospital--an orderly,
sir," the man introduced.

"Yes," encouraged Craig, "what can I do for you?"

"A Mrs. Blair has just been brought in, sir, and we can't find her
husband. She's calling for you now."

Kennedy stared from the orderly to Seward Blair, startled, speechless.

"What has happened?" asked Blair anxiously. "I am Mr. Blair."

The orderly shook his head. He had delivered his message. That was all
he knew.

"What do you suppose it is?" I asked, as we sped across town in a
taxicab. "Is it the curse that she dreaded?"

Kennedy said nothing and Blair appeared to hear nothing. His face was
drawn in tense lines.

The psychopathic ward is at once one of the most interesting and one of
the most depressing departments of a large city hospital, harboring, as
it does, all from the more or less harmless insane to violent
alcoholics and wrecked drug fiends.

Mrs. Blair, we learned, had been found hatless, without money, dazed,
having fallen, after an apparently aimless wandering in the streets.

For the moment she lay exhausted on the white bed of the ward, eyes
glazed, pupils contracted, pulse now quick, now almost evanescent, face
drawn, breathing difficult, moaning now and then in physical and mental
agony.

Until she spoke it was impossible to tell what had happened, but the
ambulance surgeon had found a little red mark on her white forearm and
had pointed it out, evidently with the idea that she was suffering from
a drug.

At the mere sight of the mark, Blair stared as though hypnotized.
Leaning over to Kennedy, so that the others could not hear, he
whispered, "It is the mark of the serpent!"

Our arrival had been announced to the hospital physician, who entered
and stood for a moment looking at the patient.

"I think it is a drug--a poison," he said meditatively.

"You haven't found out yet what it is, then?" asked Craig.

The physician shook his head doubtfully. "Whatever it is," he said
slowly, "it is closely allied to the cyanide groups in its rapacious
activity. I haven't the slightest idea of its true nature, but it seems
to have a powerful affinity for important nerve centers of respiration
and muscular coordination, as well as for disorganizing the blood. I
should say that it produces death by respiratory paralysis and
convulsions. To my mind it is an exact, though perhaps less active,
counterpart of hydrocyanic acid."

Kennedy had been listening intently at the start, but before the
physician had finished he had bent over and made a ligature quickly
with his handkerchief.

Then he dispatched a messenger with a note. Next he cut about the
minute wound on her arm until the blood flowed, cupping it to increase
the flow. Now and then he had them administer a little stimulant.

He had worked rapidly, while Blair watched him with a sort of
fascination.

"Get Dr. Vaughn," ordered Craig, as soon as he had a breathing spell
after his quick work, adding, "and Professor and Madame Rapport.
Walter, attend to that, will you? I think you will find an officer
outside. You'll have to compel them to come, if they won't come
otherwise," he added, giving the address of the Lodge, as we had found
it.

Blair shot a quick look at him, as though Craig in his knowledge were
uncanny. Apparently, the address had been a secret which he thought we
did not know.

I managed to find an officer and dispatch him for the Rapports. A
hospital orderly, I thought, would serve to get Dr. Vaughn.



CHAPTER XXIV

THE SERPENT'S TOOTH


I had scarcely returned to the ward when, suddenly, an unnatural
strength seemed to be infused into Veda.

She had risen in bed.

"It shall not catch me!" she cried in a new paroxysm of nameless
terror. "No--no--it is pursuing me. I am never out of its grasp. I have
been thought six feet underground--I know it. There it is again--still
driving me--still driving me!

"Will it never stop? Will no one stop it? Save me! It--is the death
thought!"

She had risen convulsively and had drawn back in abject, cowering
terror. What was it she saw? Evidently it was very real and very awful.
It pursued her relentlessly.

As she lay there, rolling her eyes about, she caught sight of us and
recognized us for the first time, although she had been calling for us.

"They had the thought on you, too, Professor Kennedy," she almost
screamed. "Hour after hour, Rapport and the rest repeated over and over
again, 'Why does not some one kill him? Why does he not die?' They knew
you--even when I brought you to the Red Lodge. They thought you were a
spy."

I turned to Kennedy. He had advanced and was leaning over to catch
every word. Blair was standing behind me and she had not seen her
husband yet. A quick glance showed me that he was trembling from head
to foot like a leaf, as though he, too, were pursued by the nameless
terror.

"What did they do?" Kennedy asked in a low tone.

Fearfully, gripping the bars of the iron bed, as though they were some
tangible support for her mind, she answered: "They would get together.
'Now, all of you,' they said, 'unite yourselves in thought against our
enemy, against Kennedy, that he must leave off persecuting us. He is
ripe for destruction!'"

Kennedy glanced sidewise at me, with a significant look.

"God grant," she implored, "that none haunt me for what I have done in
my ignorance!"

Just then the door opened and my messenger entered, accompanied by Dr.
Vaughn.

I had turned to catch the expression on Blair's face just in time. It
was a look of abject appeal.

Before Dr. Vaughn could ask a question, or fairly take in the
situation, Kennedy had faced him.

"What was the purpose of all that elaborate mummery out at the Red
Lodge?" asked Kennedy pointblank.

I think I looked at Craig in no less amazement than Vaughn. In spite of
the dramatic scenes through which we had passed, the spell of the
occult had not fallen on him for an instant.

"Mummery?" repeated Dr. Vaughn, bending his penetrating eyes on
Kennedy, as if he would force him to betray himself first.

"Yes," reiterated Craig. "You know as well as I do that it has been
said that it is a well-established fact that the world wants to be
deceived and is willing to pay for the privilege."

Dr. Vaughn still gazed from one to the other of us defiantly.

"You know what I mean," persisted Kennedy, "the mumbo-jumbo--just as
the Haitian obi man sticks pins in a doll or melts a wax figure of his
enemy. That is supposed to be an outward sign. But back of this
terrible power that people believe moves in darkness and mystery is
something tangible--something real."

Dr. Vaughn looked up sharply at him, I think mistaking Kennedy's
meaning. If he did, all doubt that Kennedy attributed anything to the
supernatural was removed as he went on: "At first I had no explanation
of the curious events I have just witnessed, and the more I thought
about them, the more obscure did they seem.

"I have tried to reason the thing out," he continued thoughtfully. "Did
auto-suggestion, self-hypnotism explain what I have seen? Has Veda
Blair been driven almost to death by her own fears only?"

No one interrupted and he answered his own question. "Somehow the idea
that it was purely fear that had driven her on did not satisfy me. As I
said, I wanted something more tangible. I could not help thinking that
it was not merely subjective. There was something objective, some force
at work, something more than psychic in the result achieved by this
criminal mental marauder, whoever it is."

I was following Kennedy's reasoning now closely. As he proceeded, the
point that he was making seemed more clear to me.

Persons of a certain type of mind could be really mentally unbalanced
by such methods which we had heard outlined, where the mere fact of
another trying to exert power over them became known to them. They
would, as a matter of fact, unbalance themselves, thinking about and
fighting off imaginary terrors.

Such people, I could readily see, might be quickly controlled, and in
the wake of such control would follow stifled love, wrecked homes,
ruined fortunes, suicide and even death.

Dr. Vaughn leaned forward critically. "What did you conclude, then, was
the explanation of what you saw last night?" he asked sharply.

Kennedy met his question squarely, without flinching. "It looks to me,"
he replied quietly, "like a sort of hystero-epilepsy. It is well known,
I believe, to demonologists--those who have studied this sort of thing.
They have recognized the contortions, the screams, the wild,
blasphemous talk, the cataleptic rigidity. They are epileptiform."

Vaughn said nothing, but continued to weigh Kennedy as if in a balance.
I, who knew him, knew that it would take a greater than Vaughn to find
him wanting, once Kennedy chose to speak. As for Vaughn, was he trying
to hide behind some technicality in medical ethics?

"Dr. Vaughn," continued Craig, as if goading him to the point of
breaking down his calm silence, "you are specialist enough to know
these things as well, better than I do. You must know that epilepsy is
one of the most peculiar diseases.

"The victim may be in good physical condition, apparently. In fact,
some hardly know that they have it. But it is something more than
merely the fits. Always there is something wrong mentally. It is not
the motor disturbance so much as the disturbance of consciousness."

Kennedy was talking slowly, deliberately, so that none could drop a
link in the reasoning.

"Perhaps one in ten epileptics has insane periods, more or less," he
went on, "and there is no more dangerous form of insanity.
Self-consciousness is lost, and in this state of automatism the worst
of crimes have been committed without the subsequent knowledge of the
patient. In that state they are no more responsible than are the actors
in one's dreams."

The hospital physician entered, accompanied by Craig's messenger,
breathless. Craig almost seized the package from his hands and broke
the seal.

"Ah--this is what I wanted," he exclaimed, with an air of relief,
forgetting for the time the exposition of the case that he was engaged
in. "Here I have some anti-crotalus venine, of Drs. Flexner and
Noguchi. Fortunately, in the city it is within easy reach."

Quickly, with the aid of the physician he injected it into Veda's arm.

"Of all substances in nature," he remarked, still at work over the
unfortunate woman, "none is so little known as the venom of serpents."

It was a startling idea which the sentence had raised in my mind. All
at once I recalled the first remark of Seward Blair, in which he had
repeated the password that had admitted us into the Red Lodge--"the
Serpent's Tooth." Could it have been that she had really been bitten at
some of the orgies by the serpent which they worshiped hideously
hissing in its cage? I was sure that, at least until they were
compelled, none would say anything about it. Was that the
interpretation of the almost hypnotized look on Blair's face?

"We know next to nothing of the composition of the protein bodies in
the venoms which have such terrific, quick physiological effects,"
Kennedy was saying. "They have been studied, it is true, but we cannot
really say that they are understood--or even that there are any
adequate tests by which they can be recognized. The fact is, that snake
venoms are about the safest of poisons for the criminal."

Kennedy had scarcely propounded this startling idea when a car was
heard outside. The Rapports had arrived, with the officer I had sent
after them, protesting and threatening.

They quieted down a bit as they entered, and after a quick glance
around saw who was present.

Professor Rapport gave one glance at the victim lying exhausted on the
bed, then drew back, melodramatically, and cried, "The Serpent--the
mark of the serpent!"

For a moment Kennedy gazed full in the eyes of them all.

"WAS it a snake bite?" he asked slowly, then, turning to Mrs. Blair,
after a quick glance, he went on rapidly, "The first thing to ascertain
is whether the mark consists of two isolated punctures, from the
poison-conducting teeth or fangs of the snake, which are constructed
like a hypodermic needle."

The hospital physician had bent over her at the words, and before
Kennedy could go on interrupted: "This was not a snake bite; it was
more likely from an all-glass hypodermic syringe with a
platinum-iridium needle."

Professor Rapport, priest of the Devil, advanced a step menacingly
toward Kennedy. "Remember," he said in a low, angry tone,
"remember--you are pledged to keep the secrets of the Red Lodge!"

Craig brushed aside the sophistry with a sentence. "I do not recognize
any secrets that I have to keep about the meeting this afternoon to
which you summoned the Blairs and Mrs. Langhorne, according to reports
from the shadows I had placed on Mrs. Langhorne and Dr. Vaughn."

If there is such a thing as the evil eye, Rapport's must have been a
pair of them, as he realized that Kennedy had resorted to the simple
devices of shadowing the devotees.

A cry, almost a shriek, startled us. Kennedy's encounter with Rapport
had had an effect which none of us had considered. The step or two in
advance which the prophet had taken had brought him into the line of
vision of the still half-stupefied Veda lying back of Kennedy on the
hospital cot.

The mere sight of him, the sound of his voice and the mention of the
Red Lodge had been sufficient to penetrate that stupor. She was sitting
bolt upright, a ghastly, trembling specter. Slowly a smile seemed to
creep over the cruel face of the mystic. Was it not a recognition of
his hypnotic power?

Kennedy turned and laid a gentle hand on the quaking convulsed figure
of the woman. One could feel the electric tension in the air, the
battle of two powers for good or evil. Which would win--the old
fascination of the occult or the new power of science?

It was a dramatic moment. Yet not so dramatic as the outcome. To my
surprise, neither won.

Suddenly she caught sight of her husband. Her face changed. All the
prehistoric jealousy of which woman is capable seemed to blaze forth.

"I will defend myself!" she cried. "I will fight back! She shall not
win--she shall not have you--no--she shall not--never!"

I recalled the strained feeling between the two women that I had
noticed in the cab. Was it Mrs. Langhorne who had been the disturbing
influence, whose power she feared, over herself and over her husband?

Rapport had fallen back a step, but not from the mind of Kennedy.

"Here," challenged Craig, facing the group and drawing from his pocket
the glass ampoule, "I picked this up at the Red Lodge last night."

He held it out in his hand before the Rapports so that they could not
help but see it. Were they merely good actors? They betrayed nothing,
at least by face or action.

"It is crotalin," he announced, "the venom of the rattlesnake--crotalus
horridus. It has been noticed that persons suffering from certain
diseases of which epilepsy is one, after having been bitten by a
rattlesnake, if they recover from the snake bite, are cured of the
disease."

Kennedy was forging straight ahead now in his exposure. "Crotalin," he
continued, "is one of the new drugs used in the treatment of epilepsy.
But it is a powerful two-edged instrument. Some one who knew the drug,
who perhaps had used it, has tried an artificial bite of a rattler on
Veda Blair, not for epilepsy, but for another, diabolical purpose,
thinking to cover up the crime, either as the result of the so-called
death thought of the Lodge or as the bite of the real rattler at the
Lodge."

Kennedy had at last got under Dr. Vaughn's guard. All his reticence was
gone.

"I joined the cult," he confessed. "I did it in order to observe and
treat one of my patients for epilepsy. I justified myself. I said, 'I
will be the exposer, not the accomplice, of this modern Satanism.' I
joined it and--"

"There is no use trying to shield anyone, Vaughn," rapped out Kennedy,
scarcely taking time to listen. "An epileptic of the most dangerous
criminal type has arranged this whole elaborate setting as a plot to
get rid of the wife who brought him his fortune and now stands in the
way of his unholy love of Mrs. Langhorne. He used you to get the poison
with which you treated him. He used the Rapports with money to play on
her mysticism by their so-called death thought, while he watched his
opportunity to inject the fatal crotalin."

Craig faced the criminal, whose eyes now showed more plainly than words
his deranged mental condition, and in a low tone added, "The Devil is
in you, Seward Blair!"



CHAPTER XXV

THE "HAPPY DUST"


Veda Blair's rescue from the strange use that was made of the venom
came at a time when the city was aroused as it never had been before
over the nation-wide agitation against drugs.

Already, it will be recalled, Kennedy and I had had some recent
experience with dope fiends of various kinds, but this case I set down
because it drew us more intimately into the crusade.

"I've called on you, Professor Kennedy, to see if I can't interest you
in the campaign I am planning against drugs."

Mrs. Claydon Sutphen, social leader and suffragist, had scarcely more
than introduced herself when she launched earnestly into the reason for
her visit to us.

"You don't realize it, perhaps," she continued rapidly, "but very often
a little silver bottle of tablets is as much a necessary to some women
of the smart set as cosmetics."

"I've heard of such cases," nodded Craig encouragingly.

"Well, you see I became interested in the subject," she added, "when I
saw some of my own friends going down. That's how I came to plan the
campaign in the first place."

She paused, evidently nervous. "I've been threatened, too," she went
on, "but I'm not going to give up the fight. People think that drugs
are a curse only to the underworld, but they have no idea what inroads
the habit has made in the upper world, too. Oh, it is awful!" she
exclaimed.

Suddenly, she leaned over and whispered, "Why, there's my own sister,
Mrs. Garrett. She began taking drugs after an operation, and now they
have a terrible hold on her. I needn't try to conceal anything. It's
all been published in the papers--everybody knows it. Think of
it--divorced, disgraced, all through these cursed drugs! Dr. Coleman,
our family physician, has done everything known to break up the habit,
but he hasn't succeeded."

Dr. Coleman, I knew, was a famous society physician. If he had failed,
I wondered why she thought a detective might succeed. But it was
evidently another purpose she had in mind in introducing the subject.

"So you can understand what it all means to me, personally," she
resumed, with a sigh. "I've studied the thing--I've been forced to
study it. Why, now the exploiters are even making drug fiends of
mere--children!"

Mrs. Sutphen spread out a crumpled sheet of note paper before us on
which was written something in a trembling scrawl. "For instance,
here's a letter I received only yesterday."

Kennedy glanced over it carefully. It was signed "A Friend," and read:

"I have heard of your drug war in the newspapers and wish to help you,
only I don't dare to do so openly. But I can assure you that if you
will investigate what I am about to tell you, you will soon be on the
trail of those higher up in this terrible drug business. There is a
little center of the traffic on West 66th Street, just off Broadway. I
cannot tell you more, but if you can investigate it, you will be doing
more good than you can possibly realize now. There is one girl there,
whom they call 'Snowbird.' If you could only get hold of her quietly
and place her in a sanitarium you might save her yet."

Craig was more than ordinarily interested. "And the children--what did
you mean by that?"

"Why, it's literally true," asserted Mrs. Sutphen in a horrified tone.
"Some of the victims are actually school children. Up there in 66th
Street we have found a man named Armstrong, who seems to be very
friendly with this young girl whom they call 'Snowbird.' Her real name,
by the way, is Sawtelle, I believe. She can't be over eighteen, a mere
child, yet she's a slave to the stuff."

"Oh, then you have actually already acted on the hint in the letter?"
asked Craig.

"Yes," she replied, "I've had one of the agents of our Anti-Drug
Society, a social worker, investigating the neighborhood."

Kennedy nodded for her to go on.

"I've even investigated myself a little, and now I want to employ some
one to break the thing up. My husband had heard of you and so here I
am. Can you help me?"

There was a note of appeal in her voice that was irresistible to a man
who had the heart of Kennedy.

"Tell me just what you have discovered so far," he asked simply.

"Well," she replied slowly, "after my agent verified the contents of
the letter, I watched until I saw this girl--she's a mere child, as I
said--going to a cabaret in the neighborhood. What struck me was that I
saw her go in looking like a wreck and come out a beautiful creature,
with bright eyes, flushed cheeks, almost youthful again. A most
remarkable girl she is, too," mused Mrs. Sutphen, "who always wears a
white gown, white hat, white shoes and white stockings. It must be a
mania with her."

Mrs. Sutphen seemed to have exhausted her small store of information,
and as she rose to go Kennedy rose also. "I shall be glad to look into
the case, Mrs. Sutphen," he promised. "I'm sure there is something that
can be done--there must be."

"Thank you, ever so much," she murmured, as she paused at the door,
something still on her mind. "And perhaps, too," she added, "you may
run across my sister, Mrs. Garrett."

"Indeed," he assured her, "if there is anything I can possibly do that
will assist you personally, I shall be only too happy to do it."

"Thank you again, ever so much," she repeated with just a little choke
in her voice.

For several moments Kennedy sat contemplating the anonymous letter
which she had left with him, studying both its contents and the
handwriting.

"We must go over the ground up there again," he remarked finally.
"Perhaps we can do better than Mrs. Sutphen and her drug investigator
have done."

Half an hour later we had arrived and were sauntering along the street
in question, walking slowly up and down in the now fast-gathering dusk.
It was a typical cheap apartment block of variegated character, with
people sitting idly on the narrow front steps and children spilling out
into the roadway in imminent danger of their young lives from every
passing automobile.

On the crowded sidewalk a creation in white hurtled past us. One glance
at the tense face in the flickering arc light was enough for Kennedy.
He pulled my arm and we turned and followed at a safe distance.

She looked like a girl who could not have been more than eighteen, if
she was as old as that. She was pretty, too, but already her face was
beginning to look old and worn from the use of drugs. It was
unmistakable.

In spite of the fact that she was hurrying, it was not difficult to
follow her in the crowd, as she picked her way in and out, and finally
turned into Broadway where the white lights were welcoming the night.

Under the glare of a huge electric sign she stopped a moment, then
entered one of the most notorious of the cabarets.

We entered also at a discreet distance and sat down at a table.

"Don't look around, Walter," whispered Craig, as the waiter took our
order, "but to your right is Mrs. Sutphen."

If he had mentioned any other name in the world, I could not have been
more surprised. I waited impatiently until I could pick her out from
the corner of my eye. Sure enough, it was Mrs. Sutphen and another
woman. What they were doing there I could not imagine, for neither had
the look of habitues of such a place.

I followed Kennedy's eye and found that he was gazing furtively at a
flashily dressed young man who was sitting alone at the far end in a
sort of booth upholstered in leather.

The girl in white, whom I was now sure was Miss Sawtelle, went over and
greeted him. It was too far to see just what happened, but the young
woman after sitting down rose and left almost immediately. As nearly as
I could make out, she had got something from him which she had dropped
into her handbag and was now hugging the handbag close to herself
almost as if it were gold.

We sat for a few minutes debating just what to do, when Mrs. Sutphen
and her friend rose. As she passed out, a quick, covert glance told us
to follow. We did so and the two turned into Broadway.

"Let me present you to Miss McCann," introduced Mrs. Sutphen as we
caught up with them. "Miss McCann is a social worker and trained
investigator whom I'm employing."

We bowed, but before we could ask a question, Mrs. Sutphen cried
excitedly: "I think I have a clue, anyway. We've traced the source of
the drugs at least as far as that young fellow, 'Whitecap,' whom you
saw in there."

I had not recognized his face, although I had undoubtedly seen pictures
of him before. But no sooner had I heard the name than I recognized it
as that of one of the most notorious gang leaders on the West Side.

Not only that, but Whitecap's gang played an important part in local
politics. There was scarcely a form of crime or vice to which Whitecap
and his followers could not turn a skilled hand, whether it was
swinging an election, running a gambling club, or dispensing "dope."

"You see," she explained, "even before I saw you, my suspicions were
aroused and I determined to obtain some of the stuff they are using up
here, if possible. I realized it would be useless for me to try to get
it myself, so I got Miss McCann from the Neighborhood House to try it.
She got it and has turned the bottle over to me."

"May I see it?" asked Craig eagerly.

Mrs. Sutphen reached hastily into her handbag, drew forth a small brown
glass bottle and handed it to him. Craig retreated into one of the less
dark side streets. There he pulled out the paraffinned cork from the
bottle, picked out a piece of cotton stuffed in the neck of the bottle
and poured out some flat tablets that showed a glistening white in the
palm of his hand. For an instant he regarded them.

"I may keep these?" he asked.

"Certainly," replied Mrs. Sutphen. "That's what I had Miss McCann get
them for."

Kennedy dropped the bottle into his pocket.

"So that was the gang leader, 'Whitecap,'" he remarked as we turned
again to Broadway.

"Yes," replied Mrs. Sutphen. "At certain hours, I believe he can be
found at that cabaret selling this stuff, whatever it is, to anyone who
comes properly introduced. The thing seems to be so open and notorious
that it amounts to a scandal."

We parted a moment later, Mrs. Sutphen and Miss McCann to go to the
settlement house, Craig and I to continue our investigations.

"First of all, Walter," he said as we swung aboard an uptown car, "I
want to stop at the laboratory."

In his den, which had been the scene of so many triumphs, Kennedy began
a hasty examination of the tablets, powdering one and testing it with
one chemical after another.

"What are they?" I asked at length when he seemed to have found the
right reaction which gave him the clue.

"Happy dust," he answered briefly.

"Happy dust?" I repeated, looking at him a moment in doubt as to
whether he was joking or serious. "What is that?"

"The Tenderloin name for heroin--a comparatively new derivative of
morphine. It is really morphine treated with acetic acid which renders
it more powerful than morphine alone."

"How do they take them? What's the effect?" I asked.

"The person who uses heroin usually powders the tablets and snuffs the
powder up the nose," he answered. "In a short time, perhaps only two or
three weeks, one can become a confirmed victim of 'happy dust.' And
while one is under its influence he is morally, physically and mentally
irresponsible."

Kennedy was putting away the paraphernalia he had used, meanwhile
talking about the drug. "One of the worst aspects of it, too," he
continued, "is the desire of the user to share his experience with some
one else. This passing on of the habit, which seems to be one of the
strongest desires of the drug fiend, makes him even more dangerous to
society than he would otherwise be. It makes it harder for anyone once
addicted to a drug to shake it off, for his friends will give him no
chance. The only thing to do is to get the victim out of his
environment and into an entirely new scene."

The laboratory table cleared again, Kennedy had dropped into a deep
study.

"Now, why was Mrs. Sutphen there?" he asked aloud. "I can't think it
was solely through her interest for that girl they call Snowbird. She
was interested in her, but she made no attempt to interfere or to
follow her. No, there must have been another reason."

"You don't think she's a dope fiend herself, do you?" I asked hurriedly.

Kennedy smiled. "Hardly, Walter. If she has any obsession on the
subject, it is more likely to lead her to actual fanaticism against all
stimulants and narcotics and everything connected with them. No, you
might possibly persuade me that two and two equal five--but not
seventeen. It's not very late. I think we might make another visit to
that cabaret and see whether the same thing is going on yet."



CHAPTER XXVI

THE BINET TEST


We rode downtown again and again sauntered in, this time with the
theater crowd. Our first visit had been so quiet and unostentatious
that the second attracted no attention or comment from the waiters, or
anyone else.

As we sat down we glanced over, and there in his corner still was
Whitecap. Apparently his supply of the dope was inexhaustible, for he
was still dispensing it. As we watched the tenderloin habitues come and
go, I came soon to recognize the signs by the mere look on the
face--the pasty skin, the vacant eye, the nervous quiver of the muscles
as though every organ and every nerve were crying out for more of the
favorite nepenthe. Time and again I noticed the victims as they sat at
the tables, growing more and more haggard and worn, until they could
stand it no longer. Then they would retire, sometimes after a visit
across the floor to Whitecap, more often directly, for they had stocked
themselves up with the drug evidently after the first visit to him. But
always they would come back, changed in appearance, with what seemed to
be a new lease of life, but nevertheless still as recognizable as drug
victims.

It was not long, as we waited, before another woman, older than Miss
Sawtelle, but dressed in an extreme fashion, hurried into the cabaret
and with scarcely a look to right or left went directly to Whitecap's
corner. I noticed that she, too, had the look.

There was a surreptitious passing of a bottle in exchange for a
treasury note, and she dropped into the seat beside him.

Before he could interfere, she had opened the bottle, crushed a tablet
or two in a napkin, and was holding it to her face as though breathing
the most exquisite perfume. With one quick inspiration of her breath
after another, she was snuffing the powder up her nose.

Whitecap with an angry gesture pulled the napkin from her face, and one
could fancy his snarl under his breath, "Say--do you want to get me in
wrong here?"

But it was too late. Some at least of the happy dust had taken effect,
at least enough to relieve the terrible pangs she must have been
suffering.

As she rose and retired, with a hasty apology to Whitecap for her
indiscretion, Kennedy turned to me and exclaimed, "Think of it. The
deadliest of all habits is the simplest. No hypodermic; no pipe; no
paraphernalia of any kind. It's terrible."

She returned to sit down and enjoy herself, careful not to obtrude
herself on Whitecap lest he might become angry at the mere sight of her
and treasure his anger up against the next time when she would need the
drug.

Already there was the most marvelous change in her. She seemed
captivated by the music, the dancing, the life which a few moments
before she had totally disregarded.

She was seated alone, not far from us, and as she glanced about Kennedy
caught her eye. She allowed her gaze to rest on us for a moment, the
signal for a mild flirtation which ended in our exchange of tables and
we found ourselves opposite the drug fiend, who was following up the
taking of the dope by a thin-stemmed glass of a liqueur.

I do not recall the conversation, but it was one of those
inconsequential talks that Bohemians consider so brilliant and
everybody else so vapid. As we skimmed from one subject to another,
treating the big facts of life as if they were mere incidents and the
little as if they overshadowed all else, I could see that Craig, who
had a faculty of probing into the very soul of anyone, when he chose,
was gradually leading around to a subject which I knew he wanted, above
all others, to discuss.

It was not long before, as the most natural remark in the world
following something he had made her say, just as a clever
prestidigitator forces a card, he asked, "What was it I saw you
snuffing over in the booth--happy dust?"

She did not even take the trouble to deny it, but nodded a brazen
"Yes." "How did you come to use it first?" he asked, careful not to
give offense in either tone or manner.

"The usual way, I suppose," she replied with a laugh that sounded harsh
and grating. "I was ill and I found out what it was the doctor was
giving me."

"And then?"

"Oh, I thought I would use it only as long as it served my purpose and,
when that was over, give it up."

"But--?" prompted Craig hypnotically.

"Instead, I was soon using six, eight, ten tablets of heroin a day. I
found that I needed that amount in order to live. Then it went up by
leaps to twenty, thirty, forty."

"Suppose you couldn't get it, what then?"

"Couldn't get it?" she repeated with an unspeakable horror. "Once I
thought I'd try to stop. But my heart skipped beats; then it seemed to
pound away, as if trying to break through my ribs. I don't think heroin
is like other drugs. When one has her 'coke'--that's cocaine--taken
away, she feels like a rag. Fill her up and she can do anything again.
But, heroin--I think one might murder to get it!"

The expression on the woman's face was almost tragic. I verily believe
that she meant it.

"Why," she cried, "if anyone had told me a year ago that the time would
ever come when I would value some tiny white tablets above anything
else in the world, yes, and even above my immortal soul, I would have
thought him a lunatic."

It was getting late, and as the woman showed no disposition to leave,
Kennedy and I excused ourselves.

Outside Craig looked at me keenly. "Can you guess who that was?"

"Although she didn't tell us her name," I replied, "I am morally
certain that it was Mrs. Garrett."

"Precisely," he answered, "and what a shame, too, for she must
evidently once have been a woman of great education and refinement."

He shook his head sadly. "Walter, there isn't likely to be anything
that we can do for some hours now. I have a little experiment I'd like
to make. Suppose you publish for me a story in the Star about the
campaign against drugs. Tell about what we have seen to-night, mention
the cabaret by indirection and Whitecap directly. Then we can sit back
and see what happens. We've got to throw a scare into them somehow, if
we are going to smoke out anyone higher up than Whitecap. But you'll
have to be careful, for if they suspect us our usefulness in the case
will be over."

Together, Kennedy and I worked over our story far into the night down
at the Star office, and the following day waited to see whether
anything came of it.

It was with a great deal of interest tempered by fear that we dropped
into the cabaret the following evening. Fortunately no one suspected
us. In fact, having been there the night before, we had established
ourselves, as it were, and were welcomed as old patrons and good
spenders.

I noticed, however, that Whitecap was not there. The story had been
read by such of the dope fiends as had not fallen too far to keep
abreast of the times and these and the waiters were busy quietly
warning off a line of haggard-eyed, disappointed patrons who came
around, as usual.

Some of them were so obviously dependent on Whitecap that I almost
regretted having written the story, for they must have been suffering
the tortures of the damned.

It was in the midst of a reverie of this sort that a low exclamation
from Kennedy recalled my attention. There was Snowbird with a man
considerably older than herself. They had just come in and were looking
about frantically for Whitecap. But Whitecap had been too frightened by
the story in the Star to sell any more of the magic happy dust openly
in the cabaret, at least.

The pair, nerve-racked and exhausted, sat down mournfully in a seat
near us, and as they talked earnestly in low tones we had an excellent
opportunity for studying Armstrong for the first time.

He was not a bad-looking man, or even a weak one. In back of the
dissipation of the drugs one fancied he could read the story of a
brilliant life wrecked. But there was little left to admire or respect.
As the couple talked earnestly, the one so old, the other so young in
vice, I had to keep a tight rein on myself to prevent my sympathy for
the wretched girl getting the better of common sense and kicking the
older man out of doors.

Finally Armstrong rose to go, with a final imploring glance from the
girl. Obviously she had persuaded him to forage about to secure the
heroin, by hook or crook, now that the accustomed source of supply was
cut off so suddenly.

It was also really our first chance to study the girl carefully under
the light, for her entrance and exit the night before had been so
hurried that we had seen comparatively little of her. Craig was
watching her narrowly. Not only were the effects of the drug plainly
evident on her face, but it was apparent that the snuffing the powdered
tablets was destroying the bones in her nose, through shrinkage of the
blood vessels, as well as undermining the nervous system and causing
the brain to totter.

I was wondering whether Armstrong knew of any depot for the secret
distribution of the drug. I could not believe that Whitecap was either
the chief distributer or the financial head of the illegal traffic. I
wondered who indeed was the man higher up. Was he an importer of the
drug, or was he the representative of some chemical company not averse
to making an illegal dollar now and then by dragging down his fellow
man?

Kennedy and I were trying to act as if we were enjoying the cabaret
show and not too much interested in the little drama that was being
acted before us. I think little Miss Sawtelle noticed, however, that we
were looking often her way. I was amazed, too, on studying her more
closely to find that there was something indefinably queer about her,
aside from the marked effect of the drugs she had been taking. What it
was I was at a loss to determine, but I felt sure from the expression
on Kennedy's face that he had noticed it also.

I was on the point of asking him if he, too, observed anything queer in
the girl, when Armstrong hurried in and handed her a small package,
then almost without a word stalked out again, evidently as much to
Snowbird's surprise as to our own.

She had literally seized the package, as though she were drowning and
grasping at a life buoy. Even the surprise at his hasty departure could
not prevent her, however, from literally tearing the wrapper off, and
in the sheltering shadow of the table cloth pouring forth the little
white pellets in her lap, counting them as a miser counts his gold,

"The old thief!" she exclaimed aloud. "He's held out twenty-five!"

I don't know which it was that amazed me most, the almost childish
petulance and ungovernable temper of the girl which made her cry out in
spite of her surroundings and the circumstances, or the petty rapacity
of the man who could stoop to such a low level as to rob her in this
seeming underhand manner.

There was no time for useless repining now. The call of outraged nature
for its daily and hourly quota of poison was too imperative. She dumped
the pellets back into the bottle hastily, and disappeared.

When she came back, it was with that expression I had come to know so
well. At least for a few hours there was a respite for her from the
terrific pangs she had been suffering. She was almost happy, smiling.
Even that false happiness, I felt, was superior to Armstrong's moral
sense blunted by drugs. I had begun to realize how lying, stealing,
crimes of all sorts might be laid at the door of this great evil.

In her haste to get where she could snuff the heroin she had forgotten
a light wrap lying on her chair. As she returned for it, it fell to the
floor. Instantly Kennedy was on his feet, bending over to pick it up.

She thanked him, and the smile lingered a moment on her face. It was
enough. It gave Kennedy the chance to pursue a conversation, and in the
free and easy atmosphere of the cabaret to invite her to sit over at
our table.

At least all her nervousness was gone and she chatted vivaciously.
Kennedy said little. He was too busy watching her. It was quite the
opposite of the case of Mrs. Garrett. Yet I was at a loss to define
what it was that I sensed.

Still the minutes sped past and we seemed to be getting on famously.
Unlike his action in the case of the older woman where he had been
sounding the depths of her heart and mind, in this case his idea seemed
to be to allow the childish prattle to come out and perhaps explain
itself.

However, at the end of half an hour when we seemed to be getting no
further along, Kennedy did not protest at her desire to leave us, "to
keep a date," as she expressed it.

"Waiter, the check, please," ordered Kennedy leisurely.

When he received it, he seemed to be in no great hurry to pay it, but
went over one item after another, then added up the footing again.

"Strange how some of these waiters grow rich?" Craig remarked finally
with a gay smile.

The idea of waiters and money quickly brought some petty reminiscences
to her mind. While she was still talking, Craig casually pulled a
pencil out of his pocket and scribbled some figures on the back of the
waiter's check.

From where I was sitting beside him, I could see that he had written
some figures similar to the following:

5183 47395 654726 2964375 47293815 924738651 2146073859

"Here's a stunt," he remarked, breaking into the conversation at a
convenient point. "Can you repeat these numbers after me?"

Without waiting for her to make excuse, he said quickly "5183." "5183,"
she repeated mechanically.

"47395," came in rapid succession, to which she replied, perhaps a
little slower than before,

"47395."

"Now, 654726," he said.

"654726," she repeated, I thought with some hesitation.

"Again, 2964375," he shot out.

"269," she hesitated, "73--" she stopped.

It was evident that she had reached the limit.

Kennedy smiled, paid the check and we parted at the door.

"What was all that rigmarole?" I inquired as the white figure
disappeared down the street.

"Part of the Binet test, seeing how many digits one can remember. An
adult ought to remember from eight to ten, in any order. But she has
the mentality of a child. That is the queer thing about her.
Chronologically she may be eighteen years or so old. Mentally she is
scarcely more than eight. Mrs. Sutphen was right. They have made a
fiend out of a mere child--a defective who never had a chance against
them."



CHAPTER XXVII

THE LIE DETECTOR


As the horror of it all dawned on me, I hated Armstrong worse than
ever, hated Whitecap, hated the man higher up, whoever he might be, who
was enriching himself out of the defective, as well as the weakling,
and the vicious--all three typified by Snowbird, Armstrong and Whitecap.

Having no other place to go, pending further developments of the
publicity we had given the drug war in the Star, Kennedy and I decided
on a walk home in the bracing night air.

We had scarcely entered the apartment when the hall boy called to us
frantically: "Some one's been trying to get you all over town,
Professor Kennedy. Here's the message. I wrote it down. An attempt has
been made to poison Mrs. Sutphen. They said at the other end of the
line that you'd know."

We faced each other aghast.

"My God!" exclaimed Kennedy. "Has that been the effect of our story,
Walter? Instead of smoking out anyone--we've almost killed some one."

As fast as a cab could whisk us around to Mrs. Sutphen's we hurried.

"I warned her that if she mixed up in any such fight as this she might
expect almost anything," remarked Mr. Sutphen nervously, as he met us
in the reception room. "She's all right, now, I guess, but if it hadn't
been for the prompt work of the ambulance surgeon I sent for, Dr.
Coleman says she would have died in fifteen minutes."

"How did it happen?" asked Craig.

"Why, she usually drinks a glass of vichy and milk before retiring,"
replied Mr. Sutphen. "We don't know yet whether it was the vichy or the
milk that was poisoned, but Dr. Coleman thinks it was chloral in one or
the other, and so did the ambulance surgeon. I tell you I was scared. I
tried to get Coleman, but he was out on a case, and I happened to think
of the hospitals as probably the quickest. Dr. Coleman came in just as
the young surgeon was bringing her around. He--oh, here he is now."

The famous doctor was just coming downstairs. He saw us, but, I
suppose, inasmuch as we did not belong to the Sutphen and Coleman set,
ignored us. "Mrs. Sutphen will be all right now," he said reassuringly
as he drew on his gloves. "The nurse has arrived, and I have given her
instructions what to do. And, by the way, my dear Sutphen, I should
advise you to deal firmly with her in that matter about which her name
is appearing in the papers. Women nowadays don't seem to realize the
dangers they run in mixing in in all these reforms. I have ordered an
analysis of both the milk and vichy, but that will do little good
unless we can find out who poisoned it. And there are so many chances
for things like that, life is so complex nowadays--"

He passed out with scarcely a nod at us. Kennedy did not attempt to
question him. He was thinking rapidly.

"Walter, we have no time to lose," he exclaimed, seizing a telephone
that stood on a stand near by. "This is the time for action.
Hello--Police Headquarters, First Deputy O'Connor, please."

As Kennedy waited I tried to figure out how it could have happened. I
wondered whether it might not have been Mrs. Garrett. Would she stop at
anything if she feared the loss of her favorite drug? But then there
were so many others and so many ways of "getting" anybody who
interfered with the drug traffic that it seemed impossible to figure it
out by pure deduction.

"Hello, O'Connor," I heard Kennedy say; "you read that story in the
Star this morning about the drug fiends at that Broadway cabaret? Yes?
Well, Jameson and I wrote it. It's part of the drug war that Mrs.
Sutphen has been waging. O'Connor, she's been poisoned--oh, no--she's
all right now. But I want you to send out and arrest Whitecap and that
fellow Armstrong immediately. I'm going to put them through a
scientific third degree up in the laboratory to-night. Thank you.
No--no matter how late it is, bring them up."

Dr. Coleman had gone long since, Mr. Sutphen had absolutely no interest
further than the recovery of Mrs. Sutphen just now, and Mrs. Sutphen
was resting quietly and could not be seen. Accordingly Kennedy and I
hastened up to the laboratory to wait until O'Connor could "deliver the
goods."

It was not long before one of O'Connor's men came in with Whitecap.

"While we're waiting," said Craig, "I wish you would just try this
little cut-out puzzle."

I don't know what Whitecap thought, but I know I looked at Craig's
invitation to "play blocks" as a joke scarcely higher in order than the
number repetition of Snowbird. Whitecap did it, however, sullenly, and
under compulsion, in, I should say about two minutes.

"I have Armstrong here myself," called out the voice of our old friend
O'Connor, as he burst into the room.

"Good!" exclaimed Kennedy. "I shall be ready for him in just a second.
Have Whitecap held here in the anteroom while you bring Armstrong into
the laboratory. By the way, Walter, that was another of the Binet
tests, putting a man at solving puzzles. It involves reflective
judgment, one of the factors in executive ability. If Whitecap had been
defective, it would have taken him five minutes to do that puzzle, if
at all. So you see he is not in the class with Miss Sawtelle. The test
shows him to be shrewd. He doesn't even touch his own dope. Now for
Armstrong."

I knew enough of the underworld to set Whitecap down, however, as a
"lobbygow"--an agent for some one higher up, recruiting both the gangs
and the ranks of street women.

Before us, as O'Connor led in Armstrong, was a little machine with a
big black cylinder. By means of wires and electrodes Kennedy attached
it to Armstrong's chest.

"Now, Armstrong," he began in an even tone, "I want you to tell the
truth--the whole truth. You have been getting heroin tablets from
Whitecap."

"Yes, sir," replied the dope fiend defiantly.

"To-day you had to get them elsewhere."

No answer.

"Never mind," persisted Kennedy, still calm, "I know. Why, Armstrong,
you even robbed that girl of twenty-five tablets."

"I did not," shot out the answer.

"There were twenty-five short," accused Kennedy.

The two faced each other. Craig repeated his remark.

"Yes," replied Armstrong, "I held out the tablets, but it was not for
myself, I can get all I want. I did it because I didn't want her to get
above seventy-five a day. I have tried every way to break her of the
habit that has got me--and failed. But seventy-five--is the limit!"

"A pretty story!" exclaimed O'Connor.

Craig laid his hand on his arm to check him, as he examined a record
registered on the cylinder of the machine.

"By the way, Armstrong, I want you to write me out a note that I can
use to get a hundred heroin tablets. You can write it all but the name
of the place where I can get them."

Armstrong was on the point of demurring, but the last sentence
reassured him. He would reveal nothing by it--yet.

Still the man was trembling like a leaf. He wrote:

"Give Whitecap one hundred shocks--A Victim."

For a moment Kennedy studied the note carefully. "Oh--er--I forgot,
Armstrong, but a few days ago an anonymous letter was sent to Mrs.
Sutphen, signed 'A Friend.' Do you know anything about it?"

"A note?" the man repeated. "Mrs. Sutphen? I don't know anything about
any note, or Mrs. Sutphen either."

Kennedy was still studying his record. "This," he remarked slowly, "is
what I call my psychophysical test for falsehood. Lying, when it is
practiced by an expert, is not easily detected by the most careful
scrutiny of the liar's appearance and manner.

"However, successful means have been developed for the detection of
falsehood by the study of experimental psychology. Walter, I think you
will recall the test I used once, the psychophysical factor of the
character and rapidity of the mental process known as the association
of ideas?"

I nodded acquiescence.

"Well," he resumed, "in criminal jurisprudence, I find an even more
simple and more subjective test which has been recently devised.
Professor Stoerring of Bonn has found out that feelings of pleasure and
pain produce well-defined changes in respiration. Similar effects are
produced by lying, according to the famous Professor Benussi of Graz.

"These effects are unerring, unequivocal. The utterance of a false
statement increases respiration; of a true statement decreases. The
importance and scope of these discoveries are obvious."

Craig was figuring rapidly on a piece of paper. "This is a certain and
objective criterion," he continued as he figured, "between truth and
falsehood. Even when a clever liar endeavors to escape detection by
breathing irregularly, it is likely to fail, for Benussi has
investigated and found that voluntary changes in respiration don't
alter the result. You see, the quotient obtained by dividing the time
of inspiration by the time of expiration gives me the result."

He looked up suddenly. "Armstrong, you are telling the truth about some
things--downright lies about others. You are a drug fiend--but I will
be lenient with you, for one reason. Contrary to everything that I
would have expected, you are really trying to save that poor
half-witted girl whom you love from the terrible habit that has gripped
you. That is why you held out the quarter of the one hundred tablets.
That is why you wrote the note to Mrs. Sutphen, hoping that she might
be treated in some institution."

Kennedy paused as a look of incredulity passed over Armstrong's face.

"Another thing you said was true," added Kennedy. "You can get all the
heroin you want. Armstrong, you will put the address of that place on
the outside of the note, or both you and Whitecap go to jail. Snowbird
will be left to her own devices--she can get all the 'snow,' as some of
you fiends call it, that she wants from those who might exploit her."

"Please, Mr. Kennedy," pleaded Armstrong.

"No," interrupted Craig, before the drug fiend could finish. "That is
final. I must have the name of that place."

In a shaky hand Armstrong wrote again. Hastily Craig stuffed the note
into his pocket, and ten minutes later we were mounting the steps of a
big brownstone house on a fashionable side street just around the
corner from Fifth Avenue.

As the door was opened by an obsequious colored servant, Craig handed
him the scrap of paper signed by the password, "A Victim."

Imitating the cough of a confirmed dope user, Craig was led into a
large waiting room.

"You're in pretty bad shape, sah," commented the servant.

Kennedy nudged me and, taking the cue, I coughed myself red in the face.

"Yes," he said. "Hurry--please."

The servant knocked at a door, and as it was opened we caught a glimpse
of Mrs. Garrett in negligee.

"What is it, Sam?" she asked.

"Two gentlemen for some heroin tablets, ma'am."

"Tell them to go to the chemical works--not to my office, Sam," growled
a man's voice inside.

With a quick motion, Kennedy had Mrs. Garrett by the wrist.

"I knew it," he ground out. "It was all a fake about how you got the
habit. You wanted to get it, so you could get and hold him. And neither
one of you would stop at anything, not even the murder of your sister,
to prevent the ruin of the devilish business you have built up in
manufacturing and marketing the stuff."

He pulled the note from the hand of the surprised negro. "I had the
right address, the place where you sell hundreds of ounces of the stuff
a week--but I preferred to come to the doctor's office where I could
find you both."

Kennedy had firmly twisted her wrist until, with a little scream of
pain, she let go the door handle. Then he gently pushed her aside, and
the next instant Craig had his hand inside the collar of Dr. Coleman,
society physician, proprietor of the Coleman Chemical Works downtown,
the real leader of the drug gang that was debauching whole sections of
the metropolis.



CHAPTER XXVIII

THE FAMILY SKELETON


Surprised though we were at the unmasking of Dr. Coleman, there was
nothing to do but to follow the thing out. In such cases we usually ran
into the greatest difficulty--organized vice. This was no exception.

Even when cases involved only a clever individual or a prominent
family, it was the same. I recall, for example, the case of a
well-known family in a New York suburb, which was particularly
difficult. It began in a rather unusual manner, too.

"Mr. Kennedy--I am ruined--ruined."

It was early one morning that the telephone rang and I answered it. A
very excited German, breathless and incoherent, was evidently at the
other end of the wire.

I handed the receiver to Craig and picked up the morning paper lying on
the table.

"Minturn--dead?" I heard Craig exclaim. "In the paper this morning?
I'll be down to see you directly."

Kennedy almost tore the paper from me. In the next to the end column
where late news usually is dropped was a brief account of the sudden
death of Owen Minturn, one of the foremost criminal lawyers of the
city, in Josephson's Baths downtown.

It ended: "It is believed by the coroner that Mr. Minturn was shocked
to death and evidence is being sought to show that two hundred and
forty volts of electricity had been thrown into the attorney's body
while he was in the electric bath. Joseph Josephson, the proprietor of
the bath, who operated the switchboard, is being held, pending the
completion of the inquiry."

As Kennedy hastily ran his eye over the paragraphs, he became more and
more excited himself.

"Walter," he cried, as he finished, "I don't believe that that was an
accident at all."

"Why?" I asked.

He already had his hat on, and I knew he was going to Josephson's
breakfastless. I followed reluctantly.

"Because," he answered, as we hustled along in the early morning crowd,
"it was only yesterday afternoon that I saw Minturn at his office and
he made an appointment with me for this very morning. He was a very
secretive man, but he did tell me this much, that he feared his life
was in danger and that it was in some way connected with that Pearcy
case up in Stratfield, Connecticut, where he has an estate. You have
read of the case?"

Indeed I had. It had seemed to me to be a particularly inexplicable
affair. Apparently a whole family had been poisoned and a few days
before old Mr. Randall Pearcy, a retired manufacturer, had died after a
brief but mysterious illness.

Pearcy had been married a year or so ago to Annette Oakleigh, a
Broadway comic opera singer, who was his second wife. By his first
marriage he had had two children, a son, Warner, and a daughter, Isabel.

Warner Pearcy, I had heard, had blazed a vermilion trail along the
Great White Way, but his sister was of the opposite temperament,
interested in social work, and had attracted much attention by
organizing a settlement in the slums of Stratfield for the uplift of
the workers in the Pearcy and other mills.

Broadway, as well as Stratfield, had already woven a fantastic
background, for the mystery and hints had been broadly made that
Annette Oakleigh had been indiscreetly intimate with a young physician
in the town, a Dr. Gunther, a friend, by the way, of Minturn. "There
has been no trial yet," went on Kennedy, "but Minturn seems to have
appeared before the coroner's jury at Stratfield and to have asserted
the innocence of Mrs. Pearcy and that of Dr. Gunther so well that,
although the jury brought in a verdict of murder by poison by some one
unknown, there has been no mention of the name of anyone else. The
coroner simply adjourned the inquest so that a more careful analysis
might be made of the vital organs. And now comes this second tragedy in
New York."

"What was the poison?" I asked. "Have they found out yet?"

"They are pretty sure, so Minturn told me, that it was lead poisoning.
The fact not generally known is," he added in a lower tone, "that the
cases were not confined to the Pearcy house. They had even extended to
Minturn's too, although about that he said little yesterday. The
estates up there adjoin, you know."

Owen Minturn, I recalled, had gained a formidable reputation by his
successful handling of cases from the lowest strata of society to the
highest. Indeed it was a byword that his appearance in court indicated
two things--the guilt of the accused and a verdict of acquittal.

"Of course," Craig pursued as we were jolted from station to station
downtown, "you know they say that Minturn never kept a record of a
case. But written records were as nothing compared to what that man
must have carried only in his head."

It was a common saying that, if Minturn should tell all he knew, he
might hang half a dozen prominent men in society. That was not strictly
true, perhaps, but it was certain that a revelation of the things
confided to him by clients which were never put down on paper would
have caused a series of explosions that would have wrecked at least
some portions of the social and financial world. He had heard much and
told little, for he had been a sort of "father confessor."

Had Minturn, I wondered, known the name of the real criminal?

Josephson's was a popular bath on Forty-second Street, where many of
the "sun-dodgers" were accustomed to recuperate during the day from
their arduous pursuit of pleasure at night and prepare for the
resumption of their toil during the coming night. It was more than
that, however, for it had a reputation for being conducted really on a
high plane.

We met Josephson downstairs. He had been released under bail, though
the place was temporarily closed and watched over by the agents of the
coroner and the police. Josephson appeared to be a man of some
education and quite different from what I had imagined from hearing him
over the telephone.

"Oh, Mr. Kennedy," he exclaimed, "who now will come to my baths? Last
night they were crowded, but to-day--"

He ended with an expressive gesture of his hands.

"One customer I have surely lost, young Mr. Pearcy," he went on.

"Warner Pearcy?" asked Craig. "Was he here last night?"

"Nearly every night," replied Josephson, now glib enough as his first
excitement subsided and his command of English returned. "He was a
neighbor of Mr. Minturn's, I hear. Oh, what luck!" growled Josephson as
the name recalled him to his present troubles.

"Well," remarked Kennedy with an attempt at reassurance as if to gain
the masseur's confidence, "I know as well as you that it is often
amazing what a tremendous shock a man may receive and yet not be
killed, and no less amazing how small a shock may kill. It all depends
on circumstances."

Josephson shot a covert look at Kennedy. "Yes," he reiterated, "but I
cannot see how it COULD be. If the lights had become short-circuited
with the bath, that might have thrown a current into the bath. But they
were not. I know it."

"Still," pursued Kennedy, watching him keenly, "it is not all a
question of current. To kill, the shock must pass through a vital
organ--the brain, the heart, the upper spinal cord. So, a small shock
may kill and a large one may not. If it passes in one foot and out by
the other, the current isn't likely to be as dangerous as if it passes
in by a hand or foot and then out by a foot or hand. In one case it
passes through no vital organ; in the other it is very likely to do so.
You see, the current can flow through the body only when it has a place
of entrance and a place of exit. In all cases of accident from electric
light wires, the victim is touching some conductor--damp earth, salty
earth, water, something that gives the current an outlet and--"

"But even if the lights had been short-circuited," interrupted
Josephson, "Mr. Minturn would have escaped injury unless he had touched
the taps of the bath. Oh, no, sir, accidents in the medical use of
electricity are rare. They don't happen here in my establishment," he
maintained stoutly. "The trouble was that the coroner, without any
knowledge of the physiological effects of electricity on the body,
simply jumped at once to the conclusion that it was the electric bath
that did it."

"Then it was for medical treatment that Mr. Minturn was taking the
bath?" asked Kennedy, quickly taking up the point.

"Yes, of course," answered the masseur, eager to explain. "You are
acquainted with the latest treatment for lead poisoning by means of the
electric bath?"

Kennedy nodded. "I know that Sir Thomas Oliver, the English authority
who has written much on dangerous trades, has tried it with marked
success."

"Well, sir, that was why Mr. Minturn was here. He came here introduced
by a Dr. Gunther of Stratfield."

"Indeed?" remarked Kennedy colorlessly, though I could see that it
interested him, for evidently Minturn had said nothing of being himself
a sufferer from the poison. "May I see the bath?"

"Surely," said Josephson, leading the way upstairs.

It was an oaken tub with metal rods on the two long sides, from which
depended prismatic carbon rods. Kennedy examined it closely.

"This is what we call a hydro-electric bath," Josephson explained.
"Those rods on the sides are the electrodes. You see there are no metal
parts in the tub itself. The rods are attached by wiring to a wall
switch out here."

He pointed to the next room. Kennedy examined the switch with care.

"From it," went on Josephson, "wires lead to an accumulator battery of
perhaps thirty volts. It uses very little current. Dr. Gunther tested
it and found it all right."

Craig leaned over the bath, and from the carbon electrodes scraped off
a white powder in minute crystals.

"Ordinarily," Josephson pursued, "lead is eliminated by the skin and
kidneys. But now, as you know, it is being helped along by
electrolysis. I talked to Dr. Gunther about it. It is his opinion that
it is probably eliminated as a chloride from the tissues of the body to
the electrodes in the bath in which the patient is wholly or partly
immersed. On the positive electrodes we get the peroxide. On the
negative there is a spongy metallic form of lead. But it is only a
small amount."

"The body has been removed?" asked Craig.

"Not yet," the masseur replied. "The coroner has ordered it kept here
under guard until he makes up his mind what disposition to have made of
it."

We were next ushered into a little room on the same floor, at the door
of which was posted an official from the coroner.

"First of all," remarked Craig, as he drew back the sheet and began, a
minute examination of the earthly remains of the great lawyer, "there
are to be considered the safeguards of the human body against the
passage through it of a fatal electric current--the high electric
resistance of the body itself. It is particularly high when the current
must pass through joints such as wrists, knees, elbows, and quite high
when the bones of the head are concerned. Still, there might have been
an incautious application of the current to the head, especially when
the subject is a person of advanced age or latent cerebral disease,
though I don't know that that fits Mr. Minturn. That's strange," he
muttered, looking up, puzzled. "I can find no mark of a burn on the
body--absolutely no mark of anything."

"That's what I say," put in Josephson, much pleased by what Kennedy
said, for he had been waiting anxiously to see what Craig discovered on
his own examination. "It's impossible."

"It's all the more remarkable," went on Craig, half to himself and
ignoring Josephson, "because burns due to electric currents are totally
unlike those produced in other ways. They occur at the point of
contact, usually about the arms and hands, or the head. Electricity is
much to be feared when it involves the cranial cavity." He completed
his examination of the head which once had carried secrets which
themselves must have been incandescent.

"Then, too, such burns are most often something more than superficial,
for considerable heat is developed which leads to massive destruction
and carbonization of the tissues to a considerable depth. I have seen
actual losses of substance--a lump of killed flesh surrounded by
healthy tissues. Besides, such burns show an unexpected indolence when
compared to the violent pains of ordinary burns. Perhaps that is due to
the destruction of the nerve endings. How did Minturn die? Was he
alone? Was he dead when he was discovered?"

"He was alone," replied Josephson, slowly endeavoring to tell it
exactly as he had seen it, "but that's the strange part of it. He
seemed to be suffering from a convulsion. I think he complained at
first of a feeling of tightness of his throat and a twitching of the
muscles of his hands and feet. Anyhow, he called for help. I was up
here and we rushed in. Dr. Gunther had just brought him and then had
gone away, after introducing him, and showing him the bath."

Josephson proceeded slowly, evidently having been warned that anything
he said might be used against him. "We carried him, when he was this
way, into this very room. But it was only for a short time. Then came a
violent convulsion. It seemed to extend rapidly all over his body. His
legs were rigid, his feet bent, his head back. Why, he was resting only
on his heels and the back of his head. You see, Mr. Kennedy, that
simply could not be the electric shock."

"Hardly," commented Kennedy, looking again at the body. "It looks more
like a tetanus convulsion. Yet there does not seem to be any trace of a
recent wound that might have caused lockjaw. How did he look?"

"Oh, his face finally became livid," replied Josephson. "He had a
ghastly, grinning expression, his eyes were wide, there was foam on his
mouth, and his breathing was difficult."

"Not like tetanus, either," revised Craig. "There the convulsion
usually begins with the face and progresses to the other muscles. Here
it seems to have gone the other way."

"That lasted a minute or so," resumed the masseur. "Then he sank
back--perfectly limp. I thought he was dead. But he was not. A cold
sweat broke out all over him and he was as if in a deep sleep."

"What did you do?" prompted Kennedy.

"I didn't know what to do. I called an ambulance. But the moment the
door opened, his body seemed to stiffen again. He had one other
convulsion--and when he grew limp he was dead."



CHAPTER XXIX

THE LEAD POISONER


It was a gruesome recital and I was glad to leave the baths finally
with Kennedy. Josephson was quite evidently relieved at the attitude
Craig had taken toward the coroner's conclusion that Minturn had been
shocked to death. As far as I could see, however, it added to rather
than cleared up the mystery.

Craig went directly uptown to his laboratory, in contrast with our
journey down, in abstracted silence, which was his manner when he was
trying to reason out some particularly knotty problem.

As Kennedy placed the white crystals which he had scraped off the
electrodes of the tub on a piece of dark paper in the laboratory, he
wet the tip of his finger and touched just the minutest grain to his
tongue.

The look on his face told me that something unexpected had happened. He
held a similar minute speck of the powder out to me.

It was an intensely bitter taste and very persistent, for even after we
had rinsed out our mouths it seemed to remain, clinging persistently to
the tongue.

He placed some of the grains in some pure water. They dissolved only
slightly, if at all. But in a tube in which he mixed a little ether and
chloroform they dissolved fairly readily.

Next, without a word, he poured just a drop of strong sulphuric acid on
the crystals. There was not a change in them.

Quickly he reached up into the rack and took down a bottle labeled
"Potassium Bichromate."

"Let us see what an oxidizing agent will do," he remarked.

As he gently added the bichromate, there came a most marvelous,
kaleidoscopic change. From being almost colorless, the crystals turned
instantly to a deep blue, then rapidly to purple, lilac, red, and then
the red slowly faded away and they became colorless again.

"What is it?" I asked, fascinated. "Lead?"

"N-no," he replied, the lines of his forehead deepening. "No. This is
sulphate of strychnine."

"Sulphate of strychnine?" I repeated in astonishment.

"Yes," he reiterated slowly. "I might have suspected that from the
convulsions, particularly when Josephson said that the noise and
excitement of the arrival of the ambulance brought on the fatal
paroxysm. That is symptomatic. But I didn't fully realize it until I
got up here and tasted the stuff. Then I suspected, for that taste is
characteristic. Even one part diluted seventy thousand times gives that
decided bitter taste."

"That's all very well," I remarked, recalling the intense bitterness
yet on my tongue. "But how do you suppose it was possible for anyone to
administer it? It seems to me that he would have said something, if he
had swallowed even the minutest part of it. He must have known it. Yet
apparently he didn't. At least he said nothing about it--or else
Josephson is concealing something."

"Did he swallow it--necessarily?" queried Kennedy, in a tone calculated
to show me that the chemical world, at least, was full of a number of
things, and there was much to learn.

"Well, I suppose if it had been given hypodermically, it would have a
more violent effect," I persisted, trying to figure out a way that the
poison might have been given.

"Even more unlikely," objected Craig, with a delight at discovering a
new mystery that to me seemed almost fiendish. "No, he would certainly
have felt a needle, have cried out and said something about it, if
anyone had tried that. This poisoned needle business isn't as easy as
some people seem to think nowadays."

"Then he might have absorbed it from the water," I insisted, recalling
a recent case of Kennedy's and adding, "by osmosis."

"You saw how difficult it was to dissolve in water," Craig rejected
quietly.

"Well, then," I concluded in desperation. "How could it have been
introduced?"

"I have a theory," was all he would say, reaching for the railway
guide, "but it will take me up to Stratfield to prove it."

His plan gave us a little respite and we paused long enough to lunch,
for which breathing space I was duly thankful. The forenoon saw us on
the train, Kennedy carrying a large and cumbersome package which he
brought down with him from the laboratory and which we took turns in
carrying, though he gave no hint of its contents.

We arrived in Stratfield, a very pretty little mill town, in the middle
of the afternoon, and with very little trouble were directed to the
Pearcy house, after Kennedy had checked the parcel with the station
agent.

Mrs. Pearcy, to whom we introduced ourselves as reporters of the Star,
was a tall blonde. I could not help thinking that she made a
particularly dashing widow. With her at the time was Isabel Pearcy, a
slender girl whose sensitive lips and large, earnest eyes indicated a
fine, high-strung nature.

Even before we had introduced ourselves, I could not help thinking that
there was a sort of hostility between the women. Certainly it was
evident that there was as much difference in temperament as between the
butterfly and the bee.

"No," replied the elder woman quickly to a request from Kennedy for an
interview, "there is nothing that I care to say to the newspapers. They
have said too much already about this--unfortunate affair."

Whether it was imagination or not, I fancied that there was an air of
reserve about both women. It struck me as a most peculiar household.
What was it? Was each suspicious of the other? Was each concealing
something?

I managed to steal a glance at Kennedy's face to see whether there was
anything to confirm my own impression. He was watching Mrs. Pearcy
closely as she spoke. In fact his next few questions, inconsequential
as they were, seemed addressed to her solely for the purpose of getting
her to speak.

I followed his eyes and found that he was watching her mouth, in
reality. As she answered I noted her beautiful white teeth. Kennedy
himself had trained me to notice small things, and at the time, though
I thought it was trivial, I recall noticing on her gums, where they
joined the teeth, a peculiar bluish-black line.

Kennedy had been careful to address only Mrs. Pearcy at first, and as
he continued questioning her, she seemed to realize that he was trying
to lead her along.

"I must positively refuse to talk any more," she repeated finally,
rising. "I am not to be tricked into saying anything."

She had left the room, evidently expecting that Isabel would follow.
She did not. In fact I felt that Miss Pearcy was visibly relieved by
the departure of her stepmother. She seemed anxious to ask us something
and now took the first opportunity.

"Tell me," she said eagerly, "how did Mr. Minturn die? What do they
really think of it in New York?"

"They think it is poisoning," replied Craig, noting the look on her
face.

She betrayed nothing, as far as I could see, except a natural
neighborly interest. "Poisoning?" she repeated. "By what?"

"Lead poisoning," he replied evasively.

She said nothing. It was evident that, slip of a girl though she was,
she was quite the match of anyone who attempted leading questions.
Kennedy changed his method.

"You will pardon me," he said apologetically, "for recalling what must
be distressing. But we newspapermen often have to do things and ask
questions that are distasteful. I believe it is rumored that your
father suffered from lead poisoning?"

"Oh, I don't know what it was--none of us do," she cried, almost
pathetically. "I had been living at the settlement until lately. When
father grew worse, I came home. He had such strange
visions--hallucinations, I suppose you would call them. In the daytime
he would be so very morose and melancholy. Then, too, there were
terrible pains in his stomach, and his eyesight began to fail. Yes, I
believe that Dr. Gunther did say it was lead poisoning. But--they have
said so many things--so many things," she repeated, plainly distressed
at the subject of her recent bereavement.

"Your brother is not at home?" asked Kennedy, quickly changing the
subject.

"No," she answered, then with a flash as though lifting the veil of a
confidence, added: "You know, neither Warner nor I have lived here much
this year. He has been in New York most of the time and I have been at
the settlement, as I already told you."

She hesitated, as if wondering whether she should say more, then added
quickly: "It has been repeated often enough; there is no reason why I
shouldn't say it to you. Neither of us exactly approved of father's
marriage."

She checked herself and glanced about, somewhat with the air of one who
has suddenly considered the possibility of being overheard.

"May I have a glass of water?" asked Kennedy suddenly.

"Why, certainly," she answered, going to the door, apparently eager for
an excuse to find out whether there was some one on the other side of
it.

There was not, nor any indication that there had been.

"Evidently she does not have any suspicions of THAT," remarked Kennedy
in an undertone, half to himself.

I had no chance to question him, for she returned almost immediately.
Instead of drinking the water, however, he held it carefully up to the
light. It was slightly turbid.

"You drink the water from the tap?" he asked, as he poured some of it
into a sterilized vial which he drew quickly from his vest pocket.

"Certainly," she replied, for the moment nonplussed at his strange
actions. "Everybody drinks the town water in Stratfield."

A few more questions, none of which were of importance, and Kennedy and
I excused ourselves.

At the gate, instead of turning toward the town, however, Kennedy went
on and entered the grounds of the Minturn house next door. The lawyer,
I had understood, was a widower and, though he lived in Stratfield only
part of the time, still maintained his house there.

We rang the bell and a middle-aged housekeeper answered.

"I am from the water company," he began politely. "We are testing the
water, perhaps will supply consumers with filters. Can you let me have
a sample?"

She did not demur, but invited us in. As she drew the water, Craig
watched her hands closely. She seemed to have difficulty in holding the
glass, and as she handed it to him, I noticed a peculiar hanging down
of the wrist. Kennedy poured the sample into a second vial, and I
noticed that it was turbid, too. With no mention of the tragedy to her
employer, he excused himself, and we walked slowly back to the road.

Between the two houses Kennedy paused, and for several moments appeared
to be studying them.

We walked slowly back along the road to the town. As we passed the
local drug store, Kennedy turned and sauntered in.

He found it easy enough to get into conversation with the druggist,
after making a small purchase, and in the course of a few minutes we
found ourselves gossiping behind the partition that shut off the arcana
of the prescription counter from the rest of the store.

Gradually Kennedy led the conversation around to the point which he
wanted, and asked, "I wish you'd let me fix up a little sulphureted
hydrogen."

"Go ahead," granted the druggist good-naturedly. "I guess you can do
it. You know as much about drugs as I do. I can stand the smell, if you
can."

Kennedy smiled and set to work.

Slowly he passed the gas through the samples of water he had taken from
the two houses. As he did so the gas, bubbling through, made a blackish
precipitate.

"What is it?" asked the druggist curiously.

"Lead sulphide," replied Kennedy, stroking his chin. "This is an
extremely delicate test. Why, one can get a distinct brownish tinge if
lead is present in even incredibly minute quantities."

He continued to work over the vials ranged on the table before him.

"The water contains, I should say, from ten to fifteen hundredths of a
grain of lead to the gallon," he remarked finally.

"Where did it come from?" asked the druggist, unable longer to restrain
his curiosity.

"I got it up at Pearcy's," Kennedy replied frankly, turning to observe
whether the druggist might betray any knowledge of it.

"That's strange," he replied in genuine surprise. "Our water in
Stratfield is supplied by a company to a large area, and it has always
seemed to me to be of great organic purity."

"But the pipes are of lead, are they not?" asked Kennedy.

"Y-yes," answered the druggist, "I think in most places the service
pipes are of lead. But," he added earnestly as he saw the implication
of his admission, "water has never to my knowledge been found to attack
the pipes so as to affect its quality injuriously."

He turned his own faucet and drew a glassful. "It is normally quite
clear," he added, holding the glass up.

It was in fact perfectly clear, and when he passed some of the gas
through it nothing happened at all.

Just then a man lounged into the store.

"Hello, Doctor," greeted the druggist. "Here are a couple of fellows
that have been investigating the water up at Pearcy's. They've found
lead in it. That ought to interest you. This is Dr. Gunther," he
introduced, turning to us.

It was an unexpected encounter, one I imagine that Kennedy might have
preferred to take place under other circumstances. But he was equal to
the occasion.

"We've been sent up here to look into the case for the New York Star,"
Kennedy said quickly. "I intended to come around to see you, but you
have saved me the trouble."

Dr. Gunther looked from one of us to the other. "Seems to me the New
York papers ought to have enough to do without sending men all over the
country making news," he grunted.

"Well," drawled Kennedy quietly, "there seems to be a most remarkable
situation up there at Pearcy's and Minturn's, too. As nearly as I can
make out several people there are suffering from unmistakable signs of
lead poisoning. There are the pains in the stomach, the colic, and then
on the gums is that characteristic line of plumbic sulphide, the
distinctive mark produced by lead. There is the wrist-drop, the
eyesight affected, the partial paralysis, the hallucinations and a
condition in old Pearcy's case almost bordering on insanity--to
enumerate the symptoms that seem to be present in varying degrees in
various persons in the two houses."

Gunther looked at Kennedy, as if in doubt just how to take him.

"That's what the coroner says, too--lead poisoning," put in the
druggist, himself as keen as anyone else for a piece of local news, and
evidently not averse to stimulating talk from Dr. Gunther, who had been
Pearcy's physician.

"That all seems to be true enough," replied Gunther at length
guardedly. "I recognized that some time ago."

"Why do you think it affects each so differently?" asked the druggist.

Dr. Gunther settled himself easily back in a chair to speak as one
having authority. "Well," he began slowly, "Miss Pearcy, of course,
hasn't been living there much until lately. As for the others, perhaps
this gentleman here from the Star knows that lead, once absorbed, may
remain latent in the system and then make itself felt. It is like
arsenic, an accumulative poison, slowly collecting in the body until
the limit is reached, or until the body, becoming weakened from some
other cause, gives way to it."

He shifted his position slowly, and went on, as if defending the course
of action he had taken in the case.

"Then, too, you know, there is an individual as well as family and sex
susceptibility to lead. Women are especially liable to lead poisoning,
but then perhaps in this case Mrs. Pearcy comes of a family that is
very resistant. There are many factors. Personally, I don't think
Pearcy himself was resistant. Perhaps Minturn was not, either. At any
rate, after Pearcy's death, it was I who advised Minturn to take the
electrolysis cure in New York. I took him down there," added Gunther.
"Confound it, I wish I had stayed with him. But I always found
Josephson perfectly reliable in hydrotherapy with other patients I sent
to him, and I understood that he had been very successful with cases
sent to him by many physicians in the city." He paused and I waited
anxiously to see whether Kennedy would make some reference to the
discovery of the strychnine salts.

"Have you any idea how the lead poisoning could have been caused?"
asked Kennedy instead.

Dr. Gunther shook his head. "It is a puzzle to me," he answered. "I am
sure of only one thing. It could not be from working in lead, for it is
needless to say that none of them worked."

"Food?" Craig suggested.

The doctor considered. "I had thought of that. I know that many cases
of lead poisoning have been traced to the presence of the stuff in
ordinary foods, drugs and drinks. I have examined the foods, especially
the bread. They don't use canned goods. I even went so far as to
examine the kitchen ware to see if there could be anything wrong with
the glazing. They don't drink wines and beers, into which now and then
the stuff seems to get."

"You seem to have a good grasp of the subject," flattered Kennedy, as
we rose to go. "I can hardly blame you for neglecting the water, since
everyone here seems to be so sure of the purity of the supply."

Gunther said nothing. I was not surprised, for, at the very least, no
one likes to have an outsider come in and put his finger directly on
the raw spot. What more there might be to it, I could only conjecture.

We left the druggist's and Kennedy, glancing at his watch, remarked:
"If you will go down to the station, Walter, and get that package we
left there, I shall be much obliged to you. I want to make just one
more stop, at the office of the water company, and I think I shall just
about have time for it. There's a pretty good restaurant across the
street. Meet me there, and by that time I shall know whether to carry
out a little plan I have outlined or not."



CHAPTER XXX

THE ELECTROLYTIC MURDER


We dined leisurely, which seemed strange to me, for it was not
Kennedy's custom to let moments fly uselessly when he was on a case.
However, I soon found out why it was. He was waiting for darkness.

As soon as the lights began to glow in the little stores on the main
street, we sallied forth, taking the direction of the Pearcy and
Minturn houses.

On the way he dropped into the hardware store and purchased a light
spade and one of the small pocket electric flashlights, about which he
wrapped a piece of cardboard in such a way as to make a most effective
dark lantern.

We trudged along in silence, occasionally changing from carrying the
heavy package to the light spade.

Both the Pearcy and Minturn houses were in nearly total darkness when
we arrived. They set well back from the road and were plentifully
shielded by shrubbery. Then, too, at night it was not a much frequented
neighborhood. We could easily hear the footsteps of anyone approaching
on the walk, and an occasional automobile gliding past did not worry us
in the least.

"I have calculated carefully from an examination of the water company's
map," said Craig, "just where the water pipe of the two houses branches
off from the main in the road."

After a measurement or two from some landmark, we set to work a few
feet inside, under cover of the bushes and the shadows, like two grave
diggers.

Kennedy had been wielding the spade vigorously for a few minutes when
it touched something metallic. There, just beneath the frost line, we
came upon the service pipe.

He widened the hole, and carefully scraped off the damp earth that
adhered to the pipe. Next he found a valve where he shut off the water
and cut out a small piece of the pipe.

"I hope they don't suspect anything like this in the houses with their
water cut off," he remarked as he carefully split the piece open
lengthwise and examined it under the light.

On the interior of the pipe could be seen patchy lumps of white which
projected about an eighth of an inch above the internal surface. As the
pipe dried in the warm night air, they could easily be brushed off as a
white powder.

"What is it--strychnine?" I asked.

"No," he replied, regarding it thoughtfully with some satisfaction.
"That is lead carbonate. There can be no doubt that the turbidity of
the water was due to this powder in suspension. A little dissolves in
the water, while the scales and incrustations in fine particles are
carried along in the current. As a matter of fact the amount necessary
to make the water poisonous need not be large."

He applied a little instrument to the cut ends of the pipe. As I bent
over, I could see the needle on its dial deflected just a bit.

"My voltmeter," he said, reading it, "shows that there is a current of
about 1.8 volts passing through this pipe all the time."

"Electrolysis of water pipes!" I exclaimed, thinking of statements I
had heard by engineers. "That's what they mean by stray or vagabond
currents, isn't it?"

He had seized the lantern and was eagerly following up and down the
line of the water pipe. At last he stopped, with a low exclamation, at
a point where an electric light wire supplying the Minturn cottage
crossed overhead. Fastened inconspicuously to the trunk of a tree which
served as a support for the wire was another wire which led down from
it and was buried in the ground.

Craig turned up the soft earth as fast as he could, until he reached
the pipe at this point. There was the buried wire wound several times
around it.

As quickly and as neatly as he could he inserted a connection between
the severed ends of the pipe to restore the flow of water to the
houses, turned on the water and covered up the holes he had dug. Then
he unwrapped the package which we had tugged about all day, and in a
narrow path between the bushes which led to the point where the wire
had tapped the electric light feed he placed in a shallow hole in the
ground a peculiar apparatus.

As nearly as I could make it out, it consisted of two flat platforms
between which, covered over and projected, was a slip of paper which
moved forward, actuated by clockwork, and pressed on by a sort of
stylus. Then he covered it over lightly with dirt so that, unless
anyone had been looking for it, it would never be noticed.

It was late when we reached the city again, but Kennedy had one more
piece of work and that devolved on me. All the way down on the train he
had been writing and rewriting something.

"Walter," he said, as the train pulled into the station, "I want that
published in to-morrow's papers."

I looked over what he had written. It was one of the most sensational
stories I have ever fathered, beginning, "Latest of the victims of the
unknown poisoner of whole families in Stratfield, Connecticut, is Miss
Isabel Pearcy, whose father, Randall Pearcy, died last week."

I knew that it was a "plant" of some kind, for so far he had discovered
no evidence that Miss Pearcy had been affected. What his purpose was, I
could not guess, but I got the story printed.

The next morning early Kennedy was quietly at work in the laboratory.

"What is this treatment of lead poisoning by electrolysis?" I asked,
now that there had come a lull when I might get an intelligible answer.
"How does it work?"

"Brand new, Walter," replied Kennedy. "It has been discovered that ions
will flow directly through the membranes."

"Ions?" I repeated. "What are ions?"

"Travelers," he answered, smiling, "so named by Faraday from the Greek
verb, io, to go. They are little positive and negative charges of
electricity of which molecules are composed. You know some believe now
that matter is really composed of electrical energy. I think I can
explain it best by a simile I use with my classes. It is as though you
had a ballroom in which the dancers in couples represent the neutral
molecules. There are a certain number of isolated ladies and
gentlemen--dissociated ions--" "Who don't know these new dances?" I
interrupted.

"They all know this dance," he laughed. "But, to be serious in the
simile, suppose at one end of the room there is a large mirror and at
the other a buffet with cigars and champagne. What happens to the
dissociated ions?"

"Well, I suppose you want me to say that the ladies gather about the
mirror and the men about the buffet."

"Exactly. And some of the dancing partners separate and follow the
crowd. Well, that room presents a picture of what happens in an
electrolytic solution at the moment when the electric current is
passing through it."

"Thanks," I laughed. "That was quite adequate to my immature
understanding."

Kennedy continued at work, checking up and arranging his data until the
middle of the afternoon, when he went up to Stratfield.

Having nothing better to do, I wandered out about town in the hope of
running across some one with whom to while away the hours until Kennedy
returned. I found out that, since yesterday, Broadway had woven an
entirely new background for the mystery. Now it was rumored that the
lawyer Minturn himself had been on very intimate terms with Mrs.
Pearcy. I did not pay much attention to the rumor, for I knew that
Broadway is constitutionally unable to believe that anybody is straight.

Kennedy had commissioned me to keep in touch with Josephson and I
finally managed to get around to the Baths, to find them still closed.

As I was talking with him, a very muddy and dusty car pulled up at the
door and a young man whose face was marred by the red congested blood
vessels that are in some a mark of dissipation burst in on us.

"What--closed up yet--Joe?" he asked. "Haven't they taken Minturn's
body away?"

"Yes, it was sent up to Stratfield to-day," replied the masseur, "but
the coroner seems to want to worry me all he can."

"Too bad. I was up almost all last night, and to-day I have been out in
my car--tired to death. Thought I might get some rest here. Where are
you sending the boys--to the Longacre?"

"Yes. They'll take good care of you till I open up again. Hope to see
you back again, then, Mr. Pearcy," he added, as the young man turned
and hurried out to his car again. "That was that young Pearcy, you
know. Nice boy--but living the life too fast. What's Kennedy
doing--anything?"

I did not like the jaunty bravado of the masseur which now seemed to be
returning, since nothing definite had taken shape. I determined that he
should not pump me, as he evidently was trying to do. I had at least
fulfilled Kennedy's commission and felt that the sooner I left
Josephson the better for both of us.

I was surprised at dinner to receive a wire from Craig saying that he
was bringing down Dr. Gunther, Mrs. Pearcy and Isabel to New York and
asking me to have Warner Pearcy and Josephson at the laboratory at nine
o'clock.

By strategy I managed to persuade Pearcy to come, and as for Josephson,
he could not very well escape, though I saw that as long as nothing
more had happened, he was more interested in "fixing" the police so
that he could resume business than anything else.

As we entered the laboratory that night, Kennedy, who had left his
party at a downtown hotel to freshen up, met us each at the door.
Instead of conducting us in front of his laboratory table, which was
the natural way, he led us singly around through the narrow space back
of it.

I recall that as I followed him, I half imagined that the floor gave
way just a bit, and there flashed over me, by a queer association of
ideas, the recollection of having visited an amusement park not long
before where merely stepping on an innocent-looking section of the
flooring had resulted in a tremendous knocking and banging beneath,
much to the delight of the lovers of slap-stick humor. This was serious
business, however, and I quickly banished the frivolous thought from my
mind.

"The discovery of poison, and its identification," began Craig at last
when we had all arrived and were seated about him, "often involves not
only the use of chemistry but also a knowledge of the chemical effect
of the poison on the body, and the gross as well as microscopic changes
which it produces in various tissues and organs--changes, some due to
mere contact, others to the actual chemicophysiological reaction
between the poison and the body."

His hand was resting on the poles of a large battery, as he proceeded:
"Every day the medical detective plays a more and more important part
in the detection of crime, and I might say that, except in the case of
crime complicated by a lunacy plea, his work has earned the respect of
the courts and of detectives, while in the case of insanity the
discredit is the fault rather of the law itself. The ways in which the
doctor can be of use in untangling the facts in many forms of crime
have become so numerous that the profession of medical detective may
almost be called a specialty."

Kennedy repeated what he had already told me about electrolysis, then
placed between the poles of the battery a large piece of raw beef.

He covered the negative electrode with blotting paper and soaked it in
a beaker near at hand.

"This solution," he explained, "is composed of potassium iodide. In
this other beaker I have a mixture of ordinary starch."

He soaked the positive electrode in the starch and then jammed the two
against the soft red meat. Then he applied the current.

A few moments later he withdrew the positive electrode. Both it and the
meat under it were blue!

"What has happened?" he asked. "The iodine ions have actually passed
through the beef to the positive pole and the paper on the electrode.
Here we have starch iodide."

It was a startling idea, this of the introduction of a substance by
electrolysis.

"I may say," he resumed, "that the medical view of electricity is
changing, due in large measure to the genius of the Frenchman, Dr.
Leduc. The body, we know, is composed largely of water, with salts of
soda and potash. It is an excellent electrolyte. Yet most doctors
regard the introduction of substances by the electric current as
insignificant or nonexistent. But on the contrary the introduction of
drugs by electrolysis is regular and far from being insignificant may
very easily bring about death.

"That action," he went on, looking from one of us to another, "may be
therapeutic, as in the cure for lead poisoning by removing the lead, or
it may be toxic--as in the case of actually introducing such a poison
as strychnine into the body by the same forces that will remove the
lead."

He paused a moment, to enforce the point which had already been
suggested. I glanced about hastily. If anyone in his little audience
was guilty, no one betrayed it, for all were following him, fascinated.
Yet in the wildly throbbing brain of some one of them the guilty
knowledge must be seared indelibly. Would the mere accusation be enough
to dissociate the truth from, that brain or would Kennedy have to
resort to other means?

"Some one," he went on, in a low, tense voice, leaning forward, "some
one who knew this effect placed strychnine salts on one of the
electrodes of the bath which Owen Minturn was to use."

He did not pause. Evidently he was planning to let the force of his
exposure be cumulative, until from its sheer momentum it carried
everything before it.

"Walter," he ordered quickly. "Lend me a hand."

Together we moved the laboratory table as he directed.

There, in the floor, concealed by the shadow, he had placed the same
apparatus which I had seen him bury in the path between the Pearcy and
Minturn estates at Stratfield.

We scarcely breathed.

"This," he explained rapidly, "is what is known as a kinograph--the
invention of Professor HeleShaw of London. It enables me to identify a
person by his or her walk. Each of you as you entered this room has
passed over this apparatus and has left a different mark on the paper
which registers."

For a moment he stopped, as if gathering strength for the final assault.

"Until late this afternoon I had this kinograph secreted at a certain
place in Stratfield. Some one had tampered with the leaden water pipes
and the electric light cable. Fearful that the lead poisoning brought
on by electrolysis might not produce its result in the intended victim,
that person took advantage of the new discoveries in electrolysis to
complete that work by introducing the deadly strychnine during the very
process of cure of the lead poisoning."

He slapped down a copy of a newspaper. "In the news this morning I told
just enough of what I had discovered and colored it in such a way that
I was sure I would arouse apprehension. I did it because I wanted to
make the criminal revisit the real scene of the crime. There was a
double motive now--to remove the evidence and to check the spread of
the poisoning."

He reached over, tore off the paper with a quick, decisive motion, and
laid it beside another strip, a little discolored by moisture, as
though the damp earth had touched it.

"That person, alarmed lest something in the cleverly laid plot, might
be discovered, went to a certain spot to remove the traces of the
diabolical work which were hidden there. My kinograph shows the
footsteps, shows as plainly as if I had been present, the exact person
who tried to obliterate the evidence."

An ashen pallor seemed to spread over the face of Miss Pearcy, as
Kennedy shot out the words.

"That person," he emphasized, "had planned to put out of the way one
who had brought disgrace on the Pearcy family. It was an act of private
justice."

Mrs. Pearcy could stand the strain no longer. She had broken down and
was weeping incoherently. I strained my ears to catch what she was
murmuring. It was Minturn's name, not Gunther's, that was on her lips.

"But," cried Kennedy, raising an accusatory finger from the kinograph
tracing and pointing it like the finger of Fate itself, "but the
self-appointed avenger forgot that the leaden water pipe was common to
the two houses. Old Mr. Pearcy, the wronged, died first. Isabel has
guessed the family skeleton--has tried hard to shield you, but, Warner
Pearcy, you are the murderer!"



CHAPTER XXXI

THE EUGENIC BRIDE


Scandal, such as that which Kennedy unearthed in this Pearcy case, was
never much to his liking, yet he seemed destined, about this period of
his career, to have a good deal of it.

We had scarcely finished with the indictment that followed the arrest
of young Pearcy, when we were confronted by a situation which was as
unique as it was intensely modern.

"There's absolutely no insanity in Eugenia's family," I heard a young
man remark to Kennedy, as my key turned in the lock of the laboratory
door.

For a moment I hesitated about breaking in on a confidential
conference, then reflected that, as they had probably already heard me
at the lock, I had better go in and excuse myself.

As I swung the door open, I saw a young man pacing up and down the
laboratory nervously, too preoccupied even to notice the slight noise I
had made.

He paused in his nervous walk and faced Kennedy, his back to me.

"Kennedy," he said huskily, "I wouldn't care if there was insanity in
her family--for, my God!--the tragedy of it all now--I love her!"

He turned, following Kennedy's eyes in my direction, and I saw on his
face the most haggard, haunting look of anxiety that I had ever seen on
a young person.

Instantly I recognized from the pictures I had seen in the newspapers
young Quincy Atherton, the last of this famous line of the family, who
had attracted a great deal of attention several months previously by
what the newspapers had called his search through society for a
"eugenics bride," to infuse new blood into the Atherton stock.

"You need have no fear that Mr. Jameson will be like the other
newspaper men," reassured Craig, as he introduced us, mindful of the
prejudice which the unpleasant notoriety of Atherton's marriage had
already engendered in his mind.

I recalled that when I had first heard of Atherton's "eugenic
marriage," I had instinctively felt a prejudice against the very idea
of such cold, calculating, materialistic, scientific mating, as if one
of the last fixed points were disappearing in the chaos of the social
and sex upheaval.

Now, I saw that one great fact of life must always remain. We might
ride in hydroaeroplanes, delve into the very soul by psychanalysis,
perhaps even run our machines by the internal forces of radium--even
marry according to Galton or Mendel. But there would always be love,
deep passionate love of the man for the woman, love which all the
discoveries of science might perhaps direct a little less blindly, but
the consuming flame of which not all the coldness of science could ever
quench. No tampering with the roots of human nature could ever change
the roots.

I must say that I rather liked young Atherton. He had a frank, open
face, the most prominent feature of which was his somewhat aristocratic
nose. Otherwise he impressed one as being the victim of heredity in
faults, if at all serious, against which he was struggling heroically.

It was a most pathetic story which he told, a story of how his family
had degenerated from the strong stock of his ancestors until he was the
last of the line. He told of his education, how he had fallen, a rather
wild youth bent in the footsteps of his father who had been a
notoriously good clubfellow, under the influence of a college
professor, Dr. Crafts, a classmate of his father's, of how the
professor had carefully and persistently fostered in him an idea that
had completely changed him.

"Crafts always said it was a case of eugenics against euthenics,"
remarked Atherton, "of birth against environment. He would tell me over
and over that birth gave me the clay, and it wasn't such bad clay after
all, but that environment would shape the vessel."

Then Atherton launched into a description of how he had striven to find
a girl who had the strong qualities his family germ plasm seemed to
have lost, mainly, I gathered, resistance to a taint much like manic
depressive insanity. And as he talked, it was borne in on me that,
after all, contrary to my first prejudice, there was nothing very
romantic indeed about disregarding the plain teachings of science on
the subject of marriage and one's children.

In his search for a bride, Dr. Crafts, who had founded a sort of
Eugenics Bureau, had come to advise him. Others may have looked up
their brides in Bradstreet's, or at least the Social Register. Atherton
had gone higher, had been overjoyed to find that a girl he had met in
the West, Eugenia Gilman, measured up to what his friend told him were
the latest teachings of science. He had been overjoyed because, long
before Crafts had told him, he had found out that he loved her deeply.

"And now," he went on, half choking with emotion, "she is apparently
suffering from just the same sort of depression as I myself might
suffer from if the recessive trait became active."

"What do you mean, for instance?" asked Craig.

"Well, for one thing, she has the delusion that my relatives are
persecuting her."

"Persecuting her?" repeated Craig, stifling the remark that that was
not in itself a new thing in this or any other family. "How?"

"Oh, making her feel that, after all, it is Atherton family rather than
Gilman health that counts--little remarks that when our baby is born,
they hope it will resemble Quincy rather than Eugenia, and all that
sort of thing, only worse and more cutting, until the thing has begun
to prey on her mind."

"I see," remarked Kennedy thoughtfully. "But don't you think this is a
case for a--a doctor, rather than a detective?"

Atherton glanced up quickly. "Kennedy," he answered slowly, "where
millions of dollars are involved, no one can guess to what lengths the
human mind will go--no one, except you."

"Then you have suspicions of something worse?"

"Y-yes--but nothing definite. Now, take this case. If I should die
childless, after my wife, the Atherton estate would descend to my
nearest relative, Burroughs Atherton, a cousin."

"Unless you willed it to--"

"I have already drawn a will," he interrupted, "and in case I survive
Eugenia and die childless, the money goes to the founding of a larger
Eugenics Bureau, to prevent in the future, as much as possible,
tragedies such as this of which I find myself a part. If the case is
reversed, Eugenia will get her third and the remainder will go to the
Bureau or the Foundation, as I call the new venture. But," and here
young Atherton leaned forward and fixed his large eyes keenly on us,
"Burroughs might break the will. He might show that I was of unsound
mind, or that Eugenia was, too."

"Are there no other relatives?"

"Burroughs is the nearest," he replied, then added frankly, "I have a
second cousin, a young lady named Edith Atherton, with whom both
Burroughs and I used to be very friendly."

It was evident from the way he spoke that he had thought a great deal
about Edith Atherton, and still thought well of her.

"Your wife thinks it is Burroughs who is persecuting her?" asked
Kennedy.

Atherton shrugged his shoulders.

"Does she get along badly with Edith? She knows her I presume?"

"Of course. The fact is that since the death of her mother, Edith has
been living with us. She is a splendid girl, and all alone in the world
now, and I had hopes that in New York she might meet some one and marry
well."

Kennedy was looking squarely at Atherton, wondering whether he might
ask a question without seeming impertinent. Atherton caught the look,
read it, and answered quite frankly, "To tell the truth, I suppose I
might have married Edith, before I met Eugenia, if Professor Crafts had
not dissuaded me. But it wouldn't have been real love--nor wise. You
know," he went on more frankly, now that the first hesitation was over
and he realized that if he were to gain anything at all by Kennedy's
services, there must be the utmost candor between them, "you know
cousins may marry if the stocks are known to be strong. But if there is
a defect, it is almost sure to be intensified. And so I--I gave up the
idea--never had it, in fact, so strongly as to propose to her. And when
I met Eugenia all the Athertons on the family tree couldn't have bucked
up against the combination."

He was deadly in earnest as he arose from the chair into which he had
dropped after I came in.

"Oh, it's terrible--this haunting fear, this obsession that I have had,
that, in spite of all I have tried to do, some one, somehow, will
defeat me. Then comes the situation, just at a time when Eugenia and I
feel that we have won against Fate, and she in particular needs all the
consideration and care in the world--and--and I am defeated."

Atherton was again pacing the laboratory.

"I have my car waiting outside," he pleaded. "I wish you would go with
me to see Eugenia--now."

It was impossible to resist him. Kennedy rose and I followed, not
without a trace of misgiving.

The Atherton mansion was one of the old houses of the city, a somber
stone dwelling with a garden about it on a downtown square, on which
business was already encroaching. We were admitted by a servant who
seemed to walk over the polished floors with stealthy step as if there
was something sacred about even the Atherton silence. As we waited in a
high-ceilinged drawing-room with exquisite old tapestries on the walls,
I could not help feeling myself the influence of wealth and birth that
seemed to cry out from every object of art in the house.

On the longer wall of the room, I saw a group of paintings. One, I
noted especially, must have been Atherton's ancestor, the founder of
the line. There was the same nose in Atherton, for instance, a striking
instance of heredity. I studied the face carefully. There was every
element of strength in it, and I thought instinctively that, whatever
might have been the effects of in-breeding and bad alliances, there
must still be some of that strength left in the present descendant of
the house of Atherton. The more I thought about the house, the
portrait, the whole case, the more unable was I to get out of my head a
feeling that though I had not been in such a position before, I had at
least read or heard something of which it vaguely reminded me.

Eugenia Atherton was reclining listlessly in her room in a deep leather
easy chair, when Atherton took us up at last. She did not rise to greet
us, but I noted that she was attired in what Kennedy once called, as we
strolled up the Avenue, "the expensive sloppiness of the present
styles." In her case the looseness with which her clothes hung was
exaggerated by the lack of energy with which she wore them.

She had been a beautiful girl, I knew. In fact, one could see that she
must have been. Now, however, she showed marks of change. Her eyes were
large, and protruding, not with the fire of passion which is often
associated with large eyes, but dully, set in a puffy face, a trifle
florid. Her hands seemed, when she moved them, to shake with an
involuntary tremor, and in spite of the fact that one almost could feel
that her heart and lungs were speeding with energy, she had lost weight
and no longer had the full, rounded figure of health. Her manner showed
severe mental disturbance, indifference, depression, a distressing
deterioration. All her attractive Western breeziness was gone. One felt
the tragedy of it only too keenly.

"I have asked Professor Kennedy, a specialist, to call, my dear," said
Atherton gently, without mentioning what the specialty was.

"Another one?" she queried languorously.

There was a colorless indifference in the tone which was almost tragic.
She said the words slowly and deliberately, as though even her mind
worked that way.

From the first, I saw that Kennedy had been observing Eugenia Atherton
keenly. And in the role of specialist in nervous diseases he was
enabled to do what otherwise would have been difficult to accomplish.

Gradually, from observing her mental condition of indifference which
made conversation extremely difficult as well as profitless, he began
to consider her physical condition. I knew him well enough to gather
from his manner alone as he went on that what had seemed at the start
to be merely a curious case, because it concerned the Athertons, was
looming up in his mind as unusual in itself, and was interesting him
because it baffled him.

Craig had just discovered that her pulse was abnormally high, and that
consequently she had a high temperature, and was sweating profusely.

"Would you mind turning your head, Mrs. Atherton?" he asked.

She turned slowly, half way, her eyes fixed vacantly on the floor until
we could see the once striking profile.

"No, all the way around, if you please," added Kennedy.

She offered no objection, not the slightest resistance. As she turned
her head as far as she could, Kennedy quickly placed his forefinger and
thumb gently on her throat, the once beautiful throat, now with skin
harsh and rough. Softly he moved his fingers just a fraction of an inch
over the so-called "Adam's apple" and around it for a little distance.

"Thank you," he said. "Now around to the other side."

He made no other remark as he repeated the process, but I fancied I
could tell that he had had an instant suspicion of something the moment
he touched her throat.

He rose abstractedly, bowed, and we started to leave the room,
uncertain whether she knew or cared. Quincy had fixed his eyes silently
on Craig, as if imploring him to speak, but I knew how unlikely that
was until he had confirmed his suspicion to the last slightest detail.

We were passing through a dressing room in the suite when we met a tall
young woman, whose face I instantly recognized, not because I had ever
seen it before, but because she had the Atherton nose so prominently
developed.

"My cousin, Edith," introduced Quincy.

We bowed and stood for a moment chatting. There seemed to be no reason
why we should leave the suite, since Mrs. Atherton paid so little
attention to us even when we had been in the same room. Yet a slight
movement in her room told me that in spite of her lethargy she seemed
to know that we were there and to recognize who had joined us.

Edith Atherton was a noticeable woman, a woman of temperament, not
beautiful exactly, but with a stateliness about her, an aloofness. The
more I studied her face, with its thin sensitive lips and commanding,
almost imperious eyes, the more there seemed to be something peculiar
about her. She was dressed very simply in black, but it was the
simplicity that costs. One thing was quite evident--her pride in the
family of Atherton.

And as we talked, it seemed to be that she, much more than Eugenia in
her former blooming health, was a part of the somber house. There came
over me again the impression I had received before that I had read or
heard something like this case before.

She did not linger long, but continued her stately way into the room
where Eugenia sat. And at once it flashed over me what my impression,
indefinable, half formed, was. I could not help thinking, as I saw her
pass, of the lady Madeline in "The Fall of the House of Usher."



CHAPTER XXXII

THE GERM PLASM


I regarded her with utter astonishment and yet found it impossible to
account for such a feeling. I looked at Atherton, but on his face I
could see nothing but a sort of questioning fear that only increased my
illusion, as if he, too, had only a vague, haunting premonition of
something terrible impending. Almost I began to wonder whether the
Atherton house might not crumble under the fierceness of a sudden
whirlwind, while the two women in this case, one representing the
wasted past, the other the blasted future, dragged Atherton down, as
the whole scene dissolved into some ghostly tarn. It was only for a
moment, and then I saw that the more practical Kennedy had been
examining some bottles on the lady's dresser before which we had paused.

One was a plain bottle of pellets which might have been some
homeopathic remedy.

"Whatever it is that is the matter with Eugenia," remarked Atherton,
"it seems to have baffled the doctors so far."

Kennedy said nothing, but I saw that he had clumsily overturned the
bottle and absently set it up again, as though his thoughts were far
away. Yet with a cleverness that would have done credit to a professor
of legerdemain he had managed to extract two or three of the pellets.

"Yes," he said, as he moved slowly toward the staircase in the wide
hall, "most baffling."

Atherton was plainly disappointed. Evidently he had expected Kennedy to
arrive at the truth and set matters right by some sudden piece of
wizardry, and it was with difficulty that he refrained from saying so.

"I should like to meet Burroughs Atherton," he remarked as we stood in
the wide hall on the first floor of the big house. "Is he a frequent
visitor?"

"Not frequent," hastened Quincy Atherton, in a tone that showed some
satisfaction in saying it. "However, by a lucky chance he has promised
to call to-night--a mere courtesy, I believe, to Edith, since she has
come to town on a visit."

"Good!" exclaimed Kennedy. "Now, I leave it to you, Atherton, to make
some plausible excuse for our meeting Burroughs here."

"I can do that easily."

"I shall be here early," pursued Kennedy as we left.

Back again in the laboratory to which Atherton insisted on accompanying
us in his car, Kennedy busied himself for a few minutes, crushing up
one of the tablets and trying one or two reactions with some of the
powder dissolved, while I looked on curiously.

"Craig," I remarked contemplatively, after a while, "how about Atherton
himself? Is he really free from the--er--stigmata, I suppose you call
them, of insanity?"

"You mean, may the whole trouble lie with him?" he asked, not looking
up from his work.

"Yes--and the effect on her be a sort of reflex, say, perhaps the
effect of having sold herself for money and position. In other words,
does she, did she, ever love him? We don't know that. Might it not prey
on her mind, until with the kind help of his precious relatives even
Nature herself could not stand the strain--especially in the delicate
condition in which she now finds herself?"

I must admit that I felt the utmost sympathy for the poor girl whom we
had just seen such a pitiable wreck.

Kennedy closed his eyes tightly until they wrinkled at the corners.

"I think I have found out the immediate cause of her trouble," he said
simply, ignoring my suggestion.

"What is it?" I asked eagerly.

"I can't imagine how they could have failed to guess it, except that
they never would have suspected to look for anything resembling
exophthalmic goiter in a person of her stamina," he answered,
pronouncing the word slowly. "You have heard of the thyroid gland in
the neck?"

"Yes?" I queried, for it was a mere name to me.

"It is a vascular organ lying under the chin with a sort of little
isthmus joining the two parts on either side of the windpipe," he
explained. "Well, when there is any deterioration of those glands
through any cause, all sorts of complications may arise. The thyroid is
one of the so-called ductless glands, like the adrenals above the
kidneys, the pineal gland and the pituitary body. In normal activity
they discharge into the blood substances which are carried to other
organs and are now known to be absolutely essential.

"The substances which they secrete are called 'hormones'--those
chemical messengers, as it were, by which many of the processes of the
body are regulated. In fact, no field of experimental physiology is
richer in interest than this. It seems that few ordinary drugs approach
in their effects on metabolism the hormones of the thyroid. In excess
they produce such diseases as exophthalmic goiter, and goiter is
concerned with the enlargement of the glands and surrounding tissues
beyond anything like natural size. Then, too, a defect in the glands
causes the disease known as myxedema in adults and cretinism in
children. Most of all, the gland seems to tell on the germ plasm of the
body, especially in women."

I listened in amazement, hardly knowing what to think. Did his
discovery portend something diabolical, or was it purely a defect in
nature which Dr. Crafts of the Eugenics Bureau had overlooked?

"One thing at a time, Walter," cautioned Kennedy, when I put the
question to him, scarcely expecting an answer yet.

That night in the old Atherton mansion, while we waited for Borroughs
to arrive, Kennedy, whose fertile mind had contrived to kill at least
two birds with one stone, busied himself by cutting in on the regular
telephone line and placing an extension of his own in a closet in the
library. To it he attached an ordinary telephone receiver fastened to
an arrangement which was strange to me. As nearly as I can describe it,
between the diaphragm of the regular receiver and a brownish cylinder,
like that of a phonograph, and with a needle attached, was fitted an
air chamber of small size, open to the outer air by a small hole to
prevent compression.

The work was completed expeditiously, but we had plenty of time to
wait, for Borroughs Atherton evidently did not consider that an evening
had fairly begun until nine o'clock.

He arrived at last, however, rather tall, slight of figure,
narrow-shouldered, designed for the latest models of imported fabrics.
It was evident merely by shaking hands with Burroughs that he thought
both the Athertons and the Burroughses just the right combination. He
was one of those few men against whom I conceive an instinctive
prejudice, and in this case I felt positive that, whatever faults the
Atherton germ plasm might contain, he had combined others from the
determiners of that of the other ancestors he boasted. I could not help
feeling that Eugenia Atherton was in about as unpleasant an atmosphere
of social miasma as could be imagined.

Burroughs asked politely after Eugenia, but it was evident that the
real deference was paid to Edith Atherton and that they got along very
well together. Burroughs excused himself early, and we followed soon
after.

"I think I shall go around to this Eugenics Bureau of Dr. Crafts,"
remarked Kennedy the next day, after a night's consideration of the
case.

The Bureau occupied a floor in a dwelling house uptown which had been
remodeled into an office building. Huge cabinets were stacked up
against the walls, and in them several women were engaged in filing
blanks and card records. Another part of the office consisted of an
extensive library on eugenic subjects.

Dr. Crafts, in charge of the work, whom we found in a little office in
front partitioned off by ground glass, was an old man with an alert,
vigorous mind on whom the effects of plain living and high thinking
showed plainly. He was looking over some new blanks with a young woman
who seemed to be working with him, directing the force of clerks as
well as the "field workers," who were gathering the vast mass of
information which was being studied. As we introduced ourselves, he
introduced Dr. Maude Schofield.

"I have heard of your eugenic marriage contests," began Kennedy, "more
especially of what you have done for Mr. Quincy Atherton."

"Well--not exactly a contest in that case, at least," corrected Dr.
Crafts with an indulgent smile for a layman.

"No," put in Dr. Schofield, "the Eugenics Bureau isn't a human stock
farm."

"I see," commented Kennedy, who had no such idea, anyhow. He was always
lenient with anyone who had what he often referred to as the "illusion
of grandeur."

"We advise people sometimes regarding the desirability or the
undesirability of marriage," mollified Dr. Crafts. "This is a sort of
clearing house for scientific race investigation and improvement."

"At any rate," persisted Kennedy, "after investigation, I understand,
you advised in favor of his marriage with Miss Gilman."

"Yes, Eugenia Gilman seemed to measure well up to the requirements in
such a match. Her branch of the Gilmans has always been of the
vigorous, pioneering type, as well as intellectual. Her father was one
of the foremost thinkers in the West; in fact had long held ideas on
the betterment of the race. You see that in the choice of a name for
his daughter--Eugenia."

"Then there were no recessive traits in her family," asked Kennedy
quickly, "of the same sort that you find in the Athertons?"

"None that we could discover," answered Dr. Crafts positively.

"No epilepsy, no insanity of any form?"

"No. Of course, you understand that almost no one is what might be
called eugenically perfect. Strictly speaking, perhaps not over two or
three per cent. of the population even approximates that standard. But
it seemed to me that in everything essential in this case, weakness
latent in Atherton was mating strength in Eugenia and the same way on
her part for an entirely different set of traits."

"Still," considered Kennedy, "there might have been something latent in
her family germ plasm back of the time through which you could trace
it?"

Dr. Crafts shrugged his shoulders. "There often is, I must admit,
something we can't discover because it lies too far back in the past."

"And likely to crop out after skipping generations," put in Maude
Schofield.

She evidently did not take the same liberal view in the practical
application of the matter expressed by her chief. I set it down to the
ardor of youth in a new cause, which often becomes the saner
conservatism of maturity.

"Of course, you found it much easier than usual to get at the true
family history of the Athertons," pursued Kennedy. "It is an old family
and has been prominent for generations."

"Naturally," assented Dr. Crafts.

"You know Burroughs Atherton on both lines of descent?" asked Kennedy,
changing the subject abruptly.

"Yes, fairly well," answered Crafts.

"Now, for example," went on Craig, "how would you advise him to marry?"

I saw at once that he was taking this subterfuge as a way of securing
information which might otherwise have been withheld if asked for
directly. Maude Schofield also saw it, I fancied, but this time said
nothing. "They had a grandfather who was a manic depressive on the
Atherton side," said Crafts slowly. "Now, no attempt has ever been made
to breed that defect out of the family. In the case of Burroughs, it is
perhaps a little worse, for the other side of his ancestry is not free
from the taint of alcoholism."

"And Edith Atherton?"

"The same way. They both carry it. I won't go into the Mendelian law on
the subject. We are clearing up much that is obscure. But as to
Burroughs, he should marry, if at all, some one without that particular
taint. I believe that in a few generations by proper mating most taints
might be bred out of families."

Maude Schofield evidently did not agree with Dr. Crafts on some point,
and, noticing it, he seemed to be in the position both of explaining
his contention to us and of defending it before his fair assistant.

"It is my opinion, as far as I have gone with the data," he added,
"that there is hope for many of those whose family history shows
certain nervous taints. A sweeping prohibition of such marriages would
be futile, perhaps injurious. It is necessary that the mating be
carefully made, however, to prevent intensifying the taint. You see,
though I am a eugenist I am not an extremist."

He paused, then resumed argumentatively: "Then there are other
questions, too, like that of genius with its close relation to manic
depressive insanity. Also, there is decrease enough in the birth rate,
without adding an excuse for it. No, that a young man like Atherton
should take the subject seriously, instead of spending his time in wild
dissipation, like his father, is certainly creditable, argues in itself
that there still must exist some strength in his stock.

"And, of course," he continued warmly, "when I say that weakness in a
trait--not in all traits, by any means--should marry strength and that
strength may marry weakness, I don't mean that all matches should be
like that. If we are too strict we may prohibit practically all
marriages. In Atherton's case, as in many another, I felt that I should
interpret the rule as sanely as possible."

"Strength should marry strength, and weakness should never marry,"
persisted Maude Schofield. "Nothing short of that will satisfy the true
eugenist."

"Theoretically," objected Crafts. "But Atherton was going to marry,
anyhow. The only thing for me to do was to lay down a rule which he
might follow safely. Besides, any other rule meant sure disaster."

"It was the only rule with half a chance of being followed and at any
rate," drawled Kennedy, as the eugenists wrangled, "what difference
does it make in this case? As nearly as I can make out it is Mrs.
Atherton herself, not Atherton, who is ill."

Maude Schofield had risen to return to supervising a clerk who needed
help. She left us, still unconvinced.

"That is a very clever girl," remarked Kennedy as she shut the door and
he scanned Dr. Crafts' face dosely.

"Very," assented the Doctor.

"The Schofields come of good stock?" hazarded Kennedy.

"Very," assented Dr. Crafts again.

Evidently he did not care to talk about individual cases, and I felt
that the rule was a safe one, to prevent Eugenics from becoming Gossip.
Kennedy thanked him for his courtesy, and we left apparently on the
best of terms both with Crafts and his assistant.



CHAPTER XXXIII

THE SEX CONTROL


I did not see Kennedy again that day until late in the afternoon, when
he came into the laboratory carrying a small package.

"Theory is one thing, practice is another," he remarked, as he threw
his hat and coat into a chair.

"Which means--in this case?" I prompted.

"Why, I have just seen Atherton. Of course I didn't repeat our
conversation of this morning, and I'm glad I didn't. He almost makes me
think you are right, Walter. He's obsessed by the fear of Burroughs.
Why, he even told me that Burroughs had gone so far as to take a leaf
out of his book, so to speak, get in touch with the Eugenics Bureau as
if to follow his footsteps, but really to pump them about Atherton
himself. Atherton says it's all Burroughs' plan to break his will and
that the fellow has even gone so far as to cultivate the acquaintance
of Maude Schofield, knowing that he will get no sympathy from Crafts."

"First it was Edith Atherton, now it is Maude Schofield that he hitches
up with Burroughs," I commented. "Seems to me that I have heard that
one of the first signs of insanity is belief that everyone about the
victim is conspiring against him. I haven't any love for any of
them--but I must be fair."

"Well," said Kennedy, unwrapping the package, "there IS this much to
it. Atherton says Burroughs and Maude Schofield have been seen together
more than once--and not at intellectual gatherings either. Burroughs is
a fascinating fellow to a woman, if he wants to be, and the Schofields
are at least the social equals of the Burroughs. Besides," he added,
"in spite of eugenics, feminism, and all the rest--sex, like murder,
will out. There's no use having any false ideas about THAT. Atherton
may see red--but, then, he was quite excited."

"Over what?" I asked, perplexed more than ever at the turn of events.

"He called me up in the first place. 'Can't you do something?' he
implored. 'Eugenia is getting worse all the time.' She is, too. I saw
her for a moment, and she was even more vacant than yesterday."

The thought of the poor girl in the big house somehow brought over me
again my first impression of Poe's story.

Kennedy had unwrapped the package which proved to be the instrument he
had left in the closet at Atherton's. It was, as I had observed, like
an ordinary wax cylinder phonograph record.

"You see," explained Kennedy, "it is nothing more than a successful
application at last of, say, one of those phonographs you have seen in
offices for taking dictation, placed so that the feebler vibrations of
the telephone affect it. Let us see what we have here."

He had attached the cylinder to an ordinary phonograph, and after a
number of routine calls had been run off, he came to this, in voices
which we could only guess at but not recognize, for no names were used.

"How is she to-day?"

"Not much changed--perhaps not so well."

"It's all right, though. That is natural. It is working well. I think
you might increase the dose, one tablet."

"You're sure it is all right?" (with anxiety).

"Oh, positively--it has been done in Europe."

"I hope so. It must be a boy--and an ATHERTON?"

"Never fear."

That was all. Who was it? The voices were unfamiliar to me, especially
when repeated mechanically. Besides they may have been disguised. At
any rate we had learned something. Some one was trying to control the
sex of the expected Atherton heir. But that was about all. Who it was,
we knew no better, apparently, than before.

Kennedy did not seem to care much, however. Quickly he got Quincy
Atherton on the wire and arranged for Atherton to have Dr. Crafts meet
us at the house at eight o'clock that night, with Maude Schofield. Then
he asked that Burroughs Atherton be there, and of course, Edith and
Eugenia.

We arrived almost as the clock was striking, Kennedy carrying the
phonograph record and another blank record, and a boy tugging along the
machine itself. Dr. Crafts was the next to appear, expressing surprise
at meeting us, and I thought a bit annoyed, for he mentioned that it
had been with reluctance that he had had to give up some work he had
planned for the evening. Maude Schofield, who came with him, looked
bored. Knowing that she disapproved of the match with Eugenia, I was
not surprised. Burroughs arrived, not as late as I had expected, but
almost insultingly supercilious at finding so many strangers at what
Atherton had told him was to be a family conference, in order to get
him to come. Last of all Edith Atherton descended the staircase, the
personification of dignity, bowing to each with a studied graciousness,
as if distributing largess, but greeting Burroughs with an air that
plainly showed how much thicker was blood than water. Eugenia remained
upstairs, lethargic, almost cataleptic, as Atherton told us when we
arrived.

"I trust you are not going to keep us long, Quincy," yawned Burroughs,
looking ostentatiously at his watch.

"Only long enough for Professor Kennedy to say a few words about
Eugenia," replied Atherton nervously, bowing to Kennedy.

Kennedy cleared his throat slowly.

"I don't know that I have much to say," began Kennedy, still seated. "I
suppose Mr. Atherton has told you I have been much interested in the
peculiar state of health of Mrs. Atherton?"

No one spoke, and he went on easily: "There is something I might say,
however, about the--er--what I call the chemistry of insanity. Among
the present wonders of science, as you doubtless know, none stirs the
imagination so powerfully as the doctrine that at least some forms of
insanity are the result of chemical changes in the blood. For instance,
ill temper, intoxication, many things are due to chemical changes in
the blood acting on the brain.

"Go further back. Take typhoid fever with its delirium, influenza with
its suicide mania. All due to toxins--poisons.
Chemistry--chemistry--all of them chemistry."

Craig had begun carefully so as to win their attention. He had it as he
went on: "Do we not brew within ourselves poisons which enter the
circulation and pervade the system? A sudden emotion upsets the
chemistry of the body. Or poisonous food. Or a drug. It affects many
things. But we could never have had this chemical theory unless we had
had physiological chemistry--and some carry it so far as to say that
the brain secretes thought, just as the liver secretes bile, that
thoughts are the results of molecular changes."

"You are, then, a materialist of the most pronounced type," asserted
Dr. Crafts.

Kennedy had been reaching over to a table, toying with the phonograph.
As Crafts spoke he moved a key, and I suspected that it was in order to
catch the words.

"Not entirely," he said. "No more than some eugenists."

"In our field," put in Maude Schofield, "I might express the thought
this way--the sociologist has had his day; now it is the biologist, the
eugenist."

"That expresses it," commented Kennedy, still tinkering with the
record. "Yet it does not mean that because we have new ideas, they
abolish the old. Often they only explain, amplify, supplement. For
instance," he said, looking up at Edith Atherton, "take heredity. Our
knowledge seems new, but is it? Marriages have always been dictated by
a sort of eugenics. Society is founded on that."

"Precisely," she answered. "The best families have always married into
the best families. These modern notions simply recognize what the best
people have always thought--except that it seems to me," she added with
a sarcastic flourish, "people of no ancestry are trying to force
themselves in among their betters."

"Very true, Edith," drawled Burroughs, "but we did not have to be
brought here by Quincy to learn that."

Quincy Atherton had risen during the discussion and had approached
Kennedy. Craig continued to finger the phonograph abstractedly, as he
looked up.

"About this--this insanity theory," he whispered eagerly. "You think
that the suspicions I had have been justified?"

I had been watching Kennedy's hand. As soon as Atherton had started to
speak, I saw that Craig, as before, had moved the key, evidently
registering what he said, as he had in the case of the others during
the discussion.

"One moment, Atherton," he whispered in reply, "I'm coming to that.
Now," he resumed aloud, "there is a disease, or a number of diseases,
to which my remarks about insanity a while ago might apply very well.
They have been known for some time to arise from various affections of
the thyroid glands in the neck. These glands, strange to say, if acted
on in certain ways can cause degenerations of mind and body, which are
well known, but in spite of much study are still very little
understood. For example, there is a definite interrelation between them
and sex--especially in woman."

Rapidly he sketched what he had already told me of the thyroid and the
hormones. "These hormones," added Kennedy, "are closely related to many
reactions in the body, such as even the mother's secretion of milk at
the proper time and then only. That and many other functions are due to
the presence and character of these chemical secretions from the
thyroid and other ductless glands. It is a fascinating study. For we
know that anything that will upset--reduce or increase--the hormones is
a matter intimately concerned with health. Such changes," he said
earnestly, leaning forward, "might be aimed directly at the very heart
of what otherwise would be a true eugenic marriage. It is even possible
that loss of sex itself might be made to follow deep changes of the
thyroid."

He stopped a moment. Even if he had accomplished nothing else he had
struck a note which had caused the Athertons to forget their former
superciliousness.

"If there is an oversupply of thyroid hormones," continued Craig, "that
excess will produce many changes, for instance a condition very much
like exophthalmic goiter. And," he said, straightening up, "I find that
Eugenia Atherton has within her blood an undue proportion of these
thyroid hormones. Now, is it overfunction of the glands,
hyper-secretion--or is it something else?"

No one moved as Kennedy skillfully led his disclosure along step by
step.

"That question," he began again slowly, shifting his position in the
chair, "raises in my mind, at least, a question which has often
occurred to me before. Is it possible for a person, taking advantage of
the scientific knowledge we have gained, to devise and successfully
execute a murder without fear of discovery? In other words, can a
person be removed with that technical nicety of detail which will leave
no clue and will be set down as something entirely natural, though
unfortunate?"

It was a terrible idea he was framing, and he dwelt on it so that we
might accept it at its full value. "As one doctor has said," he added,
"although toxicologists and chemists have not always possessed
infallible tests for practical use, it is at present a pretty certain
observation that every poison leaves its mark. But then on the other
hand, students of criminology have said that a skilled physician or
surgeon is about the only person now capable of carrying out a really
scientific murder.

"Which is true? It seems to me, at least in the latter case, that the
very nicety of the handiwork must often serve as a clue in itself. The
trained hand leaves the peculiar mark characteristic of its training.
No matter how shrewdly the deed is planned, the execution of it is
daily becoming a more and more difficult feat, thanks to our increasing
knowledge of microbiology and pathology."

He had risen, as he finished the sentence, every eye fixed on him, as
if he had been a master hypnotist.

"Perhaps," he said, taking off the cylinder from the phonograph and
placing on one which I knew was that which had lain in the library
closet over night, "perhaps some of the things I have said will explain
or be explained by the record on this cylinder."

He had started the machine. So magical was the effect on the little
audience that I am tempted to repeat what I had already heard, but had
not myself yet been able to explain:

"How is she to-day?"

"Not much changed--perhaps not so well."

"It's all right, though. That is natural. It is working well. I think
you might increase the dose one tablet."

"You're sure it is all right?"

"Oh, positively--it has been done in Europe."

"I hope so. It must be a boy--and an ATHERTON."

"Never fear."

No one moved a muscle. If there was anyone in the room guilty of
playing on the feelings and the health of an unfortunate woman, that
person must have had superb control of his own feelings.

"As you know," resumed Kennedy thoughtfully, "there are and have been
many theories of sex control. One of the latest, but by no means the
only one, is that it can be done by use of the extracts of various
glands administered to the mother. I do not know with what scientific
authority it was stated, but I do know that some one has recently said
that adrenalin, derived from the suprarenal glands, induces boys to
develop--cholin, from the bile of the liver, girls. It makes no
difference--in this case. There may have been a show of science. But it
was to cover up a crime. Some one has been administering to Eugenia
Atherton tablets of thyroid extract--ostensibly to aid her in
fulfilling the dearest ambition of her soul--to become the mother of a
new line of Athertons which might bear the same relation to the future
of the country as the great family of the Edwards mothered by Elizabeth
Tuttle."

He was bending over the two phonograph cylinders now, rapidly comparing
the new one which he had made and that which he had just allowed to
reel off its astounding revelation.

"When a voice speaks into a phonograph," he said, half to himself, "its
modulations received on the diaphragm are written by a needle point
upon the surface of a cylinder or disk in a series of fine waving or
zigzag lines of infinitely varying depth or breadth. Dr. Marage and
others have been able to distinguish vocal sounds by the naked eye on
phonograph records. Mr. Edison has studied them with the microscope in
his world-wide search for the perfect voice.

"In fact, now it is possible to identify voices by the records they
make, to get at the precise meaning of each slightest variation of the
lines with mathematical accuracy. They can no more be falsified than
handwriting can be forged so that modern science cannot detect it or
than typewriting can be concealed and attributed to another machine.
The voice is like a finger print, a portrait parle--unescapable."

He glanced up, then back again. "This microscope shows me," he said,
"that the voices on that cylinder you heard are identical with two on
this record which I have just made in this room."

"Walter," he said, motioning to me, "look."

I glanced into the eyepiece and saw a series of lines and curves,
peculiar waves lapping together and making an appearance in some spots
almost like tooth marks. Although I did not understand the details of
the thing, I could readily see that by study one might learn as much
about it as about loops, whorls, and arches on finger tips.

"The upper and lower lines," he explained, "with long regular waves, on
that highly magnified section of the record, are formed by the voice
with no overtones. The three lines in the middle, with rhythmic
ripples, show the overtones."

He paused a moment and faced us. "Many a person," he resumed, "is a
biotype in whom a full complement of what are called inhibitions never
develops. That is part of your eugenics. Throughout life, and in spite
of the best of training, that person reacts now and then to a certain
stimulus directly. A man stands high; once a year he falls with a
lethal quantity of alcohol. A woman, brilliant, accomplished, slips
away and spends a day with a lover as unlike herself as can be imagined.

"The voice that interests me most on these records," he went on,
emphasizing the words with one of the cylinders which he still held,
"is that of a person who has been working on the family pride of
another. That person has persuaded the other to administer to Eugenia
an extract because 'it must be a boy and an Atherton.' That person is a
high-class defective, born with a criminal instinct, reacting to it in
an artful way. Thank God, the love of a man whom theoretical eugenics
condemned, roused us in--"

A cry at the door brought us all to our feet, with hearts thumping as
if they were bursting.

It was Eugenia Atherton, wild-eyed, erect, staring.

I stood aghast at the vision. Was she really to be the Lady Madeline in
this fall of the House of Atherton?

"Edith--I--I missed you. I heard voices. Is--is it true--what this
man--says? Is my--my baby--"

Quincy Atherton leaped forward and caught her as she reeled. Quickly
Craig threw open a window for air, and as he did so leaned far out and
blew shrilly on a police whistle.

The young man looked up from Eugenia, over whom he was bending,
scarcely heeding what else went on about him. Still, there was no trace
of anger on his face, in spite of the great wrong that had been done
him. There was room for only one great emotion--only anxiety for the
poor girl who had suffered so cruelly merely for taking his name.

Kennedy saw the unspoken question in his eyes.

"Eugenia is a pure normal, as Dr. Crafts told you," he said gently. "A
few weeks, perhaps only days, of treatment--the thyroid will revert to
its normal state--and Eugenia Gilman will be the mother of a new house
of Atherton which may eclipse even the proud record of the founder of
the old."

"Who blew the whistle?" demanded a gruff voice at the door, as a tall
bluecoat puffed past the scandalized butler.

"Arrest that woman," pointed Kennedy. "She is the poisoner. Either as
wife of Burroughs, whom she fascinates and controls as she does Edith,
she planned to break the will of Quincy or, in the other event, to
administer the fortune as head of the Eugenics Foundation after the
death of Dr. Crafts, who would have followed Eugenia and Quincy
Atherton."

I followed the direction of Kennedy's accusing finger. Maude
Schofield's face betrayed more than even her tongue could have
confessed.



CHAPTER XXXIV

THE BILLIONAIRE BABY


Coming to us directly as a result of the talk that the Atherton case
provoked was another that involved the happiness of a wealthy family to
a no less degree.

"I suppose you have heard of the 'billionaire baby,' Morton Hazleton
III?" asked Kennedy of me one afternoon shortly afterward.

The mere mention of the name conjured up in my mind a picture of the
lusty two-year-old heir of two fortunes, as the feature articles in the
Star had described that little scion of wealth--his luxurious nursery,
his magnificent toys, his own motor car, a trained nurse and a
detective on guard every hour of the day and night, every possible
precaution for his health and safety.

"Gad, what a lucky kid!" I exclaimed involuntarily.

"Oh, I don't know about that," put in Kennedy. "The fortune may be
exaggerated. His happiness is, I'm sure."

He had pulled from his pocketbook a card and handed it to me. It read:
"Gilbert Butler, American representative, Lloyd's."

"Lloyd's?" I queried. "What has Lloyd's to do with the billion-dollar
baby?"

"Very much. The child has been insured with them for some fabulous sum
against accident, including kidnaping."

"Yes?" I prompted, "sensing" a story.

"Well, there seem to have been threats of some kind, I understand. Mr.
Butler has called on me once already to-day to retain my services and
is going to--ah--there he is again now."

Kennedy had answered the door buzzer himself, and Mr. Butler, a tall,
sloping-shouldered Englishman, entered.

"Has anything new developed?" asked Kennedy, introducing me.

"I can't say," replied Butler dubiously. "I rather think we have found
something that may have a bearing on the case. You know Miss Haversham,
Veronica Haversham?"

"The actress and professional beauty? Yes--at least I have seen her.
Why?"

"We hear that Morton Hazleton knows her, anyhow," remarked Butler dryly.

"Well?"

"Then you don't know the gossip?" he cut in. "She is said to be in a
sanitarium near the city. I'll have to find that out for you. It's a
fast set she has been traveling with lately, including not only
Hazleton, but Dr. Maudsley, the Hazleton physician, and one or two
others, who if they were poorer might be called desperate characters."

"Does Mrs. Hazleton know of--of his reputed intimacy?"

"I can't say that, either. I presume that she is no fool."

Morton Hazleton, Jr., I knew, belonged to a rather smart group of young
men. He had been mentioned in several near-scandals, but as far as I
knew there had been nothing quite as public and definite as this one.

"Wouldn't that account for her fears?" I asked.

"Hardly," replied Butler, shaking his head. "You see, Mrs. Hazleton is
a nervous wreck, but it's about the baby, and caused, she says, by her
fears for its safety. It came to us only in a roundabout way, through a
servant in the house who keeps us in touch. The curious feature is that
we can seem to get nothing definite from her about her fears. They may
be groundless."

Butler shrugged his shoulders and proceeded, "And they may be
well-founded. But we prefer to run no chances in a case of this kind.
The child, you know, is guarded in the house. In his perambulator he is
doubly guarded, and when he goes out for his airing in the automobile,
two men, the chauffeur and a detective, are always there, besides his
nurse, and often his mother or grandmother. Even in the nursery suite
they have iron shutters which can be pulled down and padlocked at night
and are constructed so as to give plenty of fresh air even to a
scientific baby. Master Hazleton was the best sort of risk, we thought.
But now--we don't know."

"You can protect yourselves, though," suggested Kennedy.

"Yes, we have, under the policy, the right to take certain measures to
protect ourselves in addition to the precautions taken by the
Hazletons. We have added our own detective to those already on duty.
But we--we don't know what to guard against," he concluded, perplexed.
"We'd like to know--that's all. It's too big a risk."

"I may see Mrs. Hazleton?" mused Kennedy.

"Yes. Under the circumstances she can scarcely refuse to see anyone we
send. I've arranged already for you to meet her within an hour. Is that
all right?"

"Certainly."

The Hazleton home in winter in the city was uptown, facing the river.
The large grounds adjoining made the Hazletons quite independent of the
daily infant parade which one sees along Riverside Drive.

As we entered the grounds we could almost feel the very atmosphere on
guard. We did not see the little subject of so much concern, but I
remembered his much heralded advent, when his grandparents had settled
a cold million on him, just as a reward for coming into the world.
Evidently, Morton, Sr., had hoped that Morton, Jr., would calm down,
now that there was a third generation to consider. It seemed that he
had not. I wondered if that had really been the occasion of the threats
or whatever it was that had caused Mrs. Hazleton's fears, and whether
Veronica Haversham or any of the fast set around her had had anything
to do with it.

Millicent Hazleton was a very pretty little woman, in whom one saw
instinctively the artistic temperament. She had been an actress, too,
when young Morton Hazleton married her, and at first, at least, they
had seemed very devoted to each other.

We were admitted to see her in her own library, a tastefully furnished
room on the second floor of the house, facing a garden at the side.

"Mrs. Hazleton," began Butler, smoothing the way for us, "of course you
realize that we are working in your interests. Professor Kennedy,
therefore, in a sense, represents both of us."

"I am quite sure I shall be delighted to help you," she said with an
absent expression, though not ungraciously.

Butler, having introduced us, courteously withdrew. "I leave this
entirely in your hands," he said, as he excused himself. "If you want
me to do anything more, call on me."

I must say that I was much surprised at the way she had received us.
Was there in it, I wondered, an element of fear lest if she refused to
talk suspicion might grow even greater? One could see anxiety plainly
enough on her face, as she waited for Kennedy to begin.

A few moments of general conversation then followed.

"Just what is it you fear?" he asked, after having gradually led around
to the subject. "Have there been any threatening letters?"

"N-no," she hesitated, "at least nothing--definite."

"Gossip?" he hinted.

"No." She said it so positively that I fancied it might be taken for a
plain "Yes."

"Then what is it?" he asked, very deferentially, but firmly.

She had been looking out at the garden. "You couldn't understand," she
remarked. "No detective--" she stopped.

"You may be sure, Mrs. Hazleton, that I have not come here
unnecessarily to intrude," he reassured her. "It is exactly as Mr.
Butler put it. We--want to help you."

I fancied there seemed to be something compelling about his manner. It
was at once sympathetic and persuasive. Quite evidently he was taking
pains to break down the prejudice in her mind which she had already
shown toward the ordinary detective.

"You would think me crazy," she remarked slowly. "But it is just a--a
dream--just dreams."

I don't think she had intended to say anything, for she stopped short
and looked at him quickly as if to make sure whether he could
understand. As for myself, I must say I felt a little skeptical. To my
surprise, Kennedy seemed to take the statement at its face value.

"Ah," he remarked, "an anxiety dream? You will pardon me, Mrs.
Hazleton, but before we go further let me tell you frankly that I am
much more than an ordinary detective. If you will permit me, I should
rather have you think of me as a psychologist, a specialist, one who
has come to set your mind at rest rather than to worm things from you
by devious methods against which you have to be on guard. It is just
for such an unusual case as yours that Mr. Butler has called me in. By
the way, as our interview may last a few minutes, would you mind
sitting down? I think you'll find it easier to talk if you can get your
mind perfectly at rest, and for the moment trust to the nurse and the
detectives who are guarding the garden, I am sure, perfectly."

She had been standing by the window during the interview and was quite
evidently growing more and more nervous. With a bow Kennedy placed her
at her ease on a chaise lounge.

"Now," he continued, standing near her, but out of sight, "you must try
to remain free from all external influences and impressions. Don't
move. Avoid every use of a muscle. Don't let anything distract you.
Just concentrate your attention on your psychic activities. Don't
suppress one idea as unimportant, irrelevant, or nonsensical. Simply
tell me what occurs to you in connection with the dreams--everything,"
emphasized Craig.

I could not help feeling surprised to find that she accepted Kennedy's
deferential commands, for after all that was what they amounted to.
Almost I felt that she was turning to him for help, that he had broken
down some barrier to her confidence. He seemed to exert a sort of
hypnotic influence over her.

"I have had cases before which involved dreams," he was saying quietly
and reassuringly. "Believe me, I do not share the world's opinion that
dreams are nothing. Nor yet do I believe in them superstitiously. I can
readily understand how a dream can play a mighty part in shaping the
feelings of a high-tensioned woman. Might I ask exactly what it is you
fear in your dreams?"

She sank her head back in the cushions, and for a moment closed her
eyes, half in weariness, half in tacit obedience to him. "Oh, I have
such horrible dreams," she said at length, "full of anxiety and fear
for Morton and little Morton. I can't explain it. But they are so
horrible."

Kennedy said nothing. She was talking freely at last.

"Only last night," she went on, "I dreamt that Morton was dead. I could
see the funeral, all the preparations, and the procession. It seemed
that in the crowd there was a woman. I could not see her face, but she
had fallen down and the crowd was around her. Then Dr. Maudsley
appeared. Then all of a sudden the dream changed. I thought I was on
the sand, at the seashore, or perhaps a lake. I was with Junior and it
seemed as if he were wading in the water, his head bobbing up and down
in the waves. It was like a desert, too--the sand. I turned, and there
was a lion behind me. I did not seem to be afraid of him, although I
was so close that I could almost feel his shaggy mane. Yet I feared
that he might bite Junior. The next I knew I was running with the child
in my arms. I escaped--and--oh, the relief!"

She sank back, half exhausted, half terrified still by the recollection.

"In your dream when Dr. Maudsley appeared," asked Kennedy, evidently
interested in filling in the gap, "what did he do?"

"Do?" she repeated. "In the dream? Nothing."

"Are you sure?" he asked, shooting a quick glance at her.

"Yes. That part of the dream became indistinct. I'm sure he did
nothing, except shoulder through the crowd. I think he had just
entered. Then that part of the dream seemed to end and the second part
began."

Piece by piece Kennedy went over it, putting it together as if it were
a mosaic.

"Now, the woman. You say her face was hidden?"

She hesitated. "N--no. I saw it. But it was no one I knew."

Kennedy did not dwell on the contradiction, but added, "And the crowd?"

"Strangers, too."

"Dr. Maudsley is your family physician?" he questioned.

"Yes."

"Did he call--er--yesterday?"

"He calls every day to supervise the nurse who has Junior in charge."

"Could one always be true to oneself in the face of any temptation?" he
asked suddenly.

It was a bold question. Yet such had been the gradual manner of his
leading up to it that, before she knew it, she had answered quite
frankly, "Yes--if one always thought of home and her child, I cannot
see how one could help controlling herself."

She seemed to catch her breath, almost as though the words had escaped
her before she knew it.

"Is there anything besides your dream that alarms you," he asked,
changing the subject quickly, "any suspicion of--say the servants?"

"No," she said, watching him now. "But some time ago we caught a
burglar upstairs here. He managed to escape. That has made me nervous.
I didn't think it was possible."

"Anything else?"

"No," she said positively, this time on her guard.

Kennedy saw that she had made up her mind to say no more.

"Mrs. Hazleton," he said, rising. "I can hardly thank you too much for
the manner in which you have met my questions. It will make it much
easier for me to quiet your fears. And if anything else occurs to you,
you may rest assured I shall violate no confidences in your telling me."

I could not help the feeling, however, that there was just a little air
of relief on her face as we left.



CHAPTER XXXV

THE PSYCHANALYSIS


"H--M," mused Kennedy as we walked along after leaving the house.
"There were several 'complexes,' as they are called, there--the most
interesting and important being the erotic, as usual. Now, take the
lion in the dream, with his mane. That, I suspect, was Dr. Maudsley. If
you are acquainted with him, you will recall his heavy, almost tawny
beard."

Kennedy seemed to be revolving something in his mind and I did not
interrupt. I had known him too long to feel that even a dream might not
have its value with him. Indeed, several times before he had given me
glimpses into the fascinating possibilities of the new psychology.

"In spite of the work of thousands of years, little progress has been
made in the scientific understanding of dreams," he remarked a few
moments later. "Freud, of Vienna--you recall the name?--has done most,
I think in that direction."

I recalled something of the theories of the Freudists, but said nothing.

"It is an unpleasant feature of his philosophy," he went on, "but Freud
finds the conclusion irresistible that all humanity underneath the
shell is sensuous and sensual in nature. Practically all dreams betray
some delight of the senses and sexual dreams are a large proportion.
There is, according to the theory, always a wish hidden or expressed in
a dream. The dream is one of three things, the open, the disguised or
the distorted fulfillment of a wish, sometimes recognized, sometimes
repressed.

"Anxiety dreams are among the most interesting and important Anxiety
may originate in psycho-sexual excitement, the repressed libido, as the
Freudists call it. Neurotic fear has its origin in sexual life and
corresponds to a libido which has been turned away from its object and
has not succeeded in being applied. All so-called day dreams of women
are erotic; of men they are either ambition or love.

"Often dreams, apparently harmless, turn out to be sinister if we take
pains to interpret them. All have the mark of the beast. For example,
there was that unknown woman who had fallen down and was surrounded by
a crowd. If a woman dreams that, it is sexual. It can mean only a
fallen woman. That is the symbolism. The crowd always denotes a secret.

"Take also the dream of death. If there is no sorrow felt, then there
is another cause for it. But if there is sorrow, then the dreamer
really desires death or absence. I expect to have you quarrel with
that. But read Freud, and remember that in childhood death is
synonymous with being away. Thus for example, if a girl dreams that her
mother is dead, perhaps it means only that she wishes her away so that
she can enjoy some pleasure that her strict parent, by her presence,
denies.

"Then there was that dream about the baby in the water. That, I think,
was a dream of birth. You see, I asked her practically to repeat the
dreams because there were several gaps. At such points one usually
finds first hesitation, then something that shows one of the main
complexes. Perhaps the subject grows angry at the discovery.

"Now, from the tangle of the dream thought, I find that she fears that
her husband is too intimate with another woman, and that perhaps
unconsciously she has turned to Dr. Maudsley for sympathy. Dr.
Maudsley, as I said, is not only bearded, but somewhat of a social
lion. He had called on her the day before. Of such stuff are all dream
lions when there is no fear. But she shows that she has been guilty of
no wrongdoing--she escaped, and felt relieved."

"I'm glad of that," I put in. "I don't like these scandals. On the Star
when I have to report them, I do it always under protest. I don't know
what your psychanalysis is going to show in the end, but I for one have
the greatest sympathy for that poor little woman in the big house
alone, surrounded by and dependent on servants, while her husband is
out collecting scandals."

"Which suggests our next step," he said, turning the subject. "I hope
that Butler has found out the retreat of Veronica Haversham."

We discovered Miss Haversham at last at Dr. Klemm's sanitarium, up in
the hills of Westchester County, a delightful place with a reputation
for its rest cures. Dr. Klemm was an old friend of Kennedy's, having
had some connection with the medical school at the University.

She had gone up there rather suddenly, it seemed, to recuperate. At
least that was what was given out, though there seemed to be much
mystery about her, and she was taking no treatment as far as was known.

"Who is her physician?" asked Kennedy of Dr. Klemm as we sat in his
luxurious office.

"A Dr. Maudsley of the city."

Kennedy glanced quickly at me in time to check an exclamation.

"I wonder if I could see her?"

"Why, of course--if she is willing," replied Dr. Klemm.

"I will have to have some excuse," ruminated Kennedy. "Tell her I am a
specialist in nervous troubles from the city, have been visiting one of
the other patients, anything."

Dr. Klemm pulled down a switch on a large oblong oak box on his desk,
asked for Miss Haversham, and waited a moment.

"What is that?" I asked.

"A vocaphone," replied Kennedy. "This sanitarium is quite up to date,
Klemm."

The doctor nodded and smiled. "Yes, Kennedy," he replied.
"Communicating with every suite of rooms we have the vocaphone. I find
it very convenient to have these microphones, as I suppose you would
call them, catching your words without talking into them directly as
you have to do in the telephone and then at the other end emitting the
words without the use of an earpiece, from the box itself, as if from a
megaphone horn. Miss Haversham, this is Dr. Klemm. There is a Dr.
Kennedy here visiting another patient, a specialist from New York. He'd
like very much to see you if you can spare a few minutes."

"Tell him to come up." The voice seemed to come from the vocaphone as
though she were in the room with us.

Veronica Haversham was indeed wonderful, one of the leading figures in
the night life of New York, a statuesque brunette of striking beauty,
though I had heard of often ungovernable temper. Yet there was
something strange about her face here. It seemed perhaps a little
yellow, and I am sure that her nose had a peculiar look as if she were
suffering from an incipient rhinitis. The pupils of her eyes were as
fine as pin heads, her eyebrows were slightly elevated. Indeed, I felt
that she had made no mistake in taking a rest if she would preserve the
beauty which had made her popularity so meteoric.

"Miss Haversham," began Kennedy, "they tell me that you are suffering
from nervousness. Perhaps I can help you. At any rate it will do no
harm to try. I know Dr. Maudsley well, and if he doesn't approve--well,
you may throw the treatment into the waste basket."

"I'm sure I have no reason to refuse," she said. "What would you
suggest?"

"Well, first of all, there is a very simple test I'd like to try. You
won't find that it bothers you in the least--and if I can't help you,
then no harm is done."

Again I watched Kennedy as he tactfully went through the preparations
for another kind of psychanalysis, placing Miss Haversham at her ease
on a davenport in such a way that nothing would distract her attention.
As she reclined against the leather pillows in the shadow it was not
difficult to understand the lure by which she held together the little
coterie of her intimates. One beautiful white arm, bare to the elbow,
hung carelessly over the edge of the davenport, displaying a plain gold
bracelet.

"Now," began Kennedy, on whom I knew the charms of Miss Haversham
produced a negative effect, although one would never have guessed it
from his manner, "as I read off from this list of words, I wish that
you would repeat the first thing, anything," he emphasized, "that comes
into your head, no matter how trivial it may seem. Don't force yourself
to think. Let your ideas flow naturally. It depends altogether on your
paying attention to the words and answering as quickly as you
can--remember, the first word that comes into your mind. It is easy to
do. We'll call it a game," he reassured.

Kennedy handed a copy of the list to me to record the answers. There
must have been some fifty words, apparently senseless, chosen at
random, it seemed. They were:


 head       to dance    salt        white        lie

 green      sick        new         child        to fear

 water      pride       to pray     sad          stork

 to sing    ink         money       to marry     false

 death      angry       foolish     dear         anxiety

 long       needle      despise     to quarrel   to kiss

 ship       voyage      finger      old          bride

 to pay     to sin      expensive   family       pure

 window     bread       to fall     friend       ridicule

 cold       rich        unjust      luck         to sleep


"The Jung association word test is part of the Freud psychanalysis,
also," he whispered to me, "You remember we tried something based on
the same idea once before?"

I nodded. I had heard of the thing in connection with blood-pressure
tests, but not this way.

Kennedy called out the first word, "Head," while in his hand he held a
stop watch which registered to one-fifth of a second.

Quickly she replied, "Ache," with an involuntary movement of her hand
toward her beautiful forehead.

"Good," exclaimed Kennedy. "You seem to grasp the idea better than most
of my patients."

I had recorded the answer, he the time, and we found out, I recall
afterward, that the time averaged something like two and two-fifths
seconds.

I thought her reply to the second word, "green," was curious. It came
quickly, "Envy."

However, I shall not attempt to give all the replies, but merely some
of the most significant. There did not seem to be any hesitation about
most of the words, but whenever Kennedy tried to question her about a
word that seemed to him interesting she made either evasive or
hesitating answers, until it became evident that in the back of her
head was some idea which she was repressing and concealing from us,
something that she set off with a mental "No Thoroughfare."

He had finished going through the list, and Kennedy was now studying
over the answers and comparing the time records.

"Now," he said at length, running his eye over the words again, "I want
to repeat the performance. Try to remember and duplicate your first
replies," he said.

Again we went through what at first had seemed to me to be a solemn
farce, but which I began to see was quite important. Sometimes she
would repeat the answer exactly as before. At other times a new word
would occur to her. Kennedy was keen to note all the differences in the
two lists.

One which I recall because the incident made an impression on me had to
do with the trio, "Death--life--inevitable."

"Why that?" he asked casually.

"Haven't you ever heard the saying, 'One should let nothing which one
can have escape, even if a little wrong is done; no opportunity should
be missed; life is so short, death inevitable'?"

There were several others which to Kennedy seemed more important, but
long after we had finished I pondered this answer. Was that her
philosophy of life? Undoubtedly she would never have remembered the
phrase if it had not been so, at least in a measure.

She had begun to show signs of weariness, and Kennedy quickly brought
the conversation around to subjects of apparently a general nature, but
skillfully contrived so as to lead the way along lines her answers had
indicated.

Kennedy had risen to go, still chatting. Almost unintentionally he
picked up from a dressing table a bottle of white tablets, without a
label, shaking it to emphasize an entirely, and I believe purposely,
irrelevant remark.

"By the way," he said, breaking off naturally, "what is that?"

"Only something Dr. Maudsley had prescribed for me," she answered
quickly.

As he replaced the bottle and went on with the thread of the
conversation, I saw that in shaking the bottle he had abstracted a
couple of the tablets before she realized it. "I can't tell you just
what to do without thinking the case over," he concluded, rising to go.
"Yours is a peculiar case, Miss Haversham, baffling. I'll have to study
it over, perhaps ask Dr. Maudsley If I may see you again. Meanwhile, I
am sure what he is doing is the correct thing."

Inasmuch as she had said nothing about what Dr. Maudsley was doing, I
wondered whether there was not just a trace of suspicion in her glance
at him from under her long dark lashes.

"I can't see that you have done anything," she remarked pointedly. "But
then doctors are queer--queer."

That parting shot also had in it, for me, something to ponder over. In
fact I began to wonder if she might not be a great deal more clever
than even Kennedy gave her credit for being, whether she might not have
submitted to his tests for pure love of pulling the wool over his eyes.

Downstairs again, Kennedy paused only long enough to speak a few words
with his friend Dr. Klemm.

"I suppose you have no idea what Dr. Maudsley has prescribed for her?"
he asked carelessly.

"Nothing, as far as I know, except rest and simple food."

He seemed to hesitate, then he said under his voice, "I suppose you
know that she is a regular dope fiend, seasons her cigarettes with
opium, and all that."

"I guessed as much," remarked Kennedy, "but how does she get it here?"

"She doesn't."

"I see," remarked Craig, apparently weighing now the man before him. At
length he seemed to decide to risk something.

"Klemm," he said, "I wish you would do something for me. I see you have
the vocaphone here. Now if--say Hazleton--should call--will you listen
in on that vocaphone for me?" Dr. Klemm looked squarely at him.

"Kennedy," he said, "it's unprofessional, but---"

"So it is to let her be doped up under guise of a cure."

"What?" he asked, startled. "She's getting the stuff now?"

"No, I didn't say she was getting opium, or from anyone here. All the
same, if you would just keep an ear open---"

"It's unprofessional, but--you'd not ask it without a good reason. I'll
try."

It was very late when we got back to the city and we dined at an uptown
restaurant which we had almost to ourselves.

Kennedy had placed the little whitish tablets in a small paper packet
for safe keeping. As we waited for our order he drew one from his
pocket, and after looking at it a moment crushed it to a powder in the
paper.

"What is it?" I asked curiously. "Cocaine?"

"No," he said, shaking his head doubtfully.

He had tried to dissolve a little of the powder in some water from the
glass before him, but it would not dissolve.

As he continued to look at it his eye fell on the cut-glass vinegar
cruet before us. It was full of the white vinegar.

"Really acetic acid," he remarked, pouring out a little.

The white powder dissolved.

For several minutes he continued looking at the stuff.

"That, I think," he remarked finally, "is heroin."

"More 'happy dust'?" I replied with added interest now, thinking of our
previous case. "Is the habit so extensive?"

"Yes," he replied, "the habit is comparatively new, although in Paris,
I believe, they call the drug fiends, 'heroinomaniacs.' It is, as I
told you before, a derivative of morphine. Its scientific name is
diacetyl-morphin. It is New York's newest peril, one of the most
dangerous drugs yet. Thousands are slaves to it, although its sale is
supposedly restricted. It is rotting the heart out of the Tenderloin.
Did you notice Veronica Haversham's yellowish whiteness, her down-drawn
mouth, elevated eyebrows, and contracted eyes? She may have taken it up
to escape other drugs. Some people have--and have just got a new habit.
It can be taken hypodermically, or in a tablet, or by powdering the
tablet to a white crystalline powder and snuffing up the nose. That's
the way she takes it. It produces rhinitis of the nasal passages, which
I see you observed, but did not understand. It has a more profound
effect than morphine, and is ten times as powerful as codeine. And one
of the worst features is that so many people start with it, thinking it
is as harmless as it has been advertised. I wouldn't be surprised if
she used from seventy-five to a hundred one-twelfth grain tablets a
day. Some of them do, you know."

"And Dr. Maudsley," I asked quickly, "do you think it is through him or
in spite of him?"

"That's what I'd like to know. About those words," he continued, "what
did you make of the list and the answers?"

I had made nothing and said so, rather quickly.

"Those," he explained, "were words selected and arranged to strike
almost all the common complexes in analyzing and diagnosing. You'd
think any intelligent person could give a fluent answer to them,
perhaps a misleading answer. But try it yourself, Walter. You'll find
you can't. You may start all right, but not all the words will be
reacted to in the same time or with the same smoothness and ease. Yet,
like the expressions of a dream, they often seem senseless. But they
have a meaning as soon as they are 'psychanalyzed.' All the mistakes in
answering the second time, for example, have a reason, if we can only
get at it. They are not arbitrary answers, but betray the inmost
subconscious thoughts, those things marked, split off from
consciousness and repressed into the unconscious. Associations, like
dreams, never lie. You may try to conceal the emotions and unconscious
actions, but you can't."

I listened, fascinated by Kennedy's explanation.

"Anyone can see that that woman has something on her mind besides the
heroin habit. It may be that she is trying to shake the habit off in
order to do it; it may be that she seeks relief from her thoughts by
refuge in the habit; and it may be that some one has purposely caused
her to contract this new habit in the guise of throwing off an old. The
only way by which to find out is to study the case."

He paused. He had me keenly on edge, but I knew that he was not yet in
a position to answer his queries positively.

"Now I found," he went on, "that the religious complexes were extremely
few; as I expected the erotic were many. If you will look over the
three lists you will find something queer about every such word as,
'child, 'to marry,' 'bride,' 'to lie,' 'stork,' and so on. We're on the
right track. That woman does know something about that child."

"My eye catches the words 'to sin,' 'to fall,' 'pure,' and others," I
remarked, glancing over the list.

"Yes, there's something there, too. I got the hint for the drug from
her hesitation over 'needle' and 'white.' But the main complex has to
do with words relating to that child and to love. In short, I think we
are going to find it to be the reverse of the rule of the French, that
it will be a case of 'cherchez l'homme.'"

Early the next day Kennedy, after a night of studying over the case,
journeyed up to the sanitarium again. We found Dr. Klemm eager to meet
us.

"What is it?" asked Kennedy, equally eager.

"I overheard some surprising things over the vocaphone," he hastened.
"Hazleton called. Why, there must have been some wild orgies in that
precious set of theirs, and, would you believe it, many of them seem to
have been at what Dr. Maudsley calls his 'stable studio,' a den he has
fixed up artistically over his garage on a side street."

"Indeed?"

"I couldn't get it all, but I did hear her repeating over and over to
Hazleton, 'Aren't you all mine? Aren't you all mine?' There must be
some vague jealousy lurking in the heart of that ardent woman. I can't
figure it out."

"I'd like to see her again," remarked Kennedy. "Will you ask her if I
may?"



CHAPTER XXXVI

THE ENDS OF JUSTICE


A few minutes later we were in the sitting room of her suite. She
received us rather ungraciously, I thought.

"Do you feel any better?" asked Kennedy.

"No," she replied curtly. "Excuse me for a moment. I wish to see that
maid of mine. Clarisse!"

She had hardly left the room when Kennedy was on his feet. The bottle
of white tablets, nearly empty, was still on the table. I saw him take
some very fine white powder and dust it quickly over the bottle. It
seemed to adhere, and from his pocket he quickly drew a piece of what
seemed to be specially prepared paper, laid it over the bottle where
the powder adhered, fitting it over the curves. He withdrew it quickly,
for outside we heard her light step, returning. I am sure she either
saw or suspected that Kennedy had been touching the bottle of tablets,
for there was a look of startled fear on her face.

"Then you do not feel like continuing the tests we abandoned last
night?" asked Kennedy, apparently not noticing her look.

"No, I do not," she almost snapped. "You--you are detectives. Mrs.
Hazleton has sent you."

"Indeed, Mrs. Hazleton has not sent us," insisted Kennedy, never for an
instant showing his surprise at her mention of the name.

"You are. You can tell her, you can tell everybody. I'll tell--I'll
tell myself. I won't wait. That child is mine--mine--not hers. Now--go!"

Veronica Haversham on the stage never towered in a fit of passion as
she did now in real life, as her ungovernable feelings broke forth
tempestuously on us.

I was astounded, bewildered at the revelation, the possibilities in
those simple words, "The child is mine." For a moment I was stunned.
Then as the full meaning dawned on me I wondered in a flood of
consciousness whether it was true. Was it the product of her
drug-disordered brain? Had her desperate love for Hazleton produced a
hallucination?

Kennedy, silent, saw that the case demanded quick action. I shall never
forget the breathless ride down from the sanitarium to the Hazleton
house on Riverside Drive.

"Mrs. Hazleton," he cried, as we hurried in, "you will pardon me for
this unceremonious intrusion, but it is most important. May I trouble
you to place your fingers on this paper--so?"

He held out to her a piece of the prepared paper. She looked at him
once, then saw from his face that he was not to be questioned. Almost
tremulously she did as he said, saying not a word. I wondered whether
she knew the story of Veronica, or whether so far only hints of it had
been brought to her.

"Thank you," he said quickly. "Now, if I may see Morton?"

It was the first time we had seen the baby about whom the rapidly
thickening events were crowding. He was a perfect specimen of
well-cared-for, scientific infant.

Kennedy took the little chubby fingers playfully in his own. He seemed
at once to win the child's confidence, though he may have violated
scientific rules. One by one he pressed the little fingers on the
paper, until little Morton crowed with delight as one little piggy
after another "went to market." He had deserted thousands of dollars'
worth of toys just to play with the simple piece of paper Kennedy had
brought with him. As I looked at him, I thought of what Kennedy had
said at the start. Perhaps this innocent child was not to be envied
after all. I could hardly restrain my excitement over the astounding
situation which had suddenly developed.

"That will do," announced Kennedy finally, carelessly folding up the
paper and slipping it into his pocket. "You must excuse me now."

"You see," he explained on the way to the laboratory, "that powder
adheres to fresh finger prints, taking all the gradations. Then the
paper with its paraffine and glycerine coating takes off the powder."

In the laboratory he buried himself in work, with microscope compasses,
calipers, while I fumed impotently at the window.

"Walter," he called suddenly, "get Dr. Maudsley on the telephone. Tell
him to come immediately to the laboratory."

Meanwhile Kennedy was busy arranging what he had discovered in logical
order and putting on it the finishing touches.

As Dr. Maudsley entered Kennedy greeted him and began by plunging
directly into the case in answer to his rather discourteous inquiry as
to why he had been so hastily summoned.

"Dr. Maudsley," said Craig, "I have asked you to call alone because,
while I am on the verge of discovering the truth in an important case
affecting Morton Hazleton and his wife, I am frankly perplexed as to
how to go ahead."

The doctor seemed to shake with excitement as Kennedy proceeded.

"Dr. Maudsley," Craig added, dropping his voice, "is Morton III the son
of Millicent Hazleton or not? You were the physician in attendance on
her at the birth. Is he?"

Maudsley had been watching Kennedy furtively at first, but as he rapped
out the words I thought the doctor's eyes would pop out of his head.
Perspiration in great beads collected on his face.

"P--professor K--Kennedy," he muttered, frantically rubbing his face
and lower jaw as if to compose the agitation he could so ill conceal,
"let me explain."

"Yes, yes--go on," urged Kennedy.

"Mrs. Hazleton's baby was born--dead. I knew how much she and the rest
of the family had longed for an heir, how much it meant. And
I--substituted for the dead child a newborn baby from the maternity
hospital. It--it belonged to Veronica Haversham--then a poor chorus
girl. I did not intend that she should ever know it. I intended that
she should think her baby was dead. But in some way she found out.
Since then she has become a famous beauty, has numbered among her
friends even Hazleton himself. For nearly two years I have tried to
keep her from divulging the secret. From time to time hints of it have
leaked out. I knew that if Hazleton with his infatuation of her were to
learn---"

"And Mrs. Hazleton, has she been told?" interrupted Kennedy.

"I have been trying to keep it from her as long as I can, but it has
been difficult to keep Veronica from telling it. Hazleton himself was
so wild over her. And she wanted her son as she---"

"Maudsley," snapped out Kennedy, slapping down on the table the mass of
prints and charts which he had hurriedly collected and was studying,
"you lie! Morton is Millicent Hazleton's son. The whole story is
blackmail. I knew it when she told me of her dreams and I suspected
first some such devilish scheme as yours. Now I know it scientifically."

He turned over the prints.

"I suppose that study of these prints, Maudsley, will convey nothing to
you. I know that it is usually stated that there are no two sets of
finger prints in the world that are identical or that can be confused.
Still, there are certain similarities of finger prints and other
characteristics, and these similarities have recently been exhaustively
studied by Bertilion, who has found that there are clear relationships
sometimes between mother and child in these respects. If Solomon were
alive, doctor, he would not now have to resort to the expedient to
which he did when the two women disputed over the right to the living
child. Modern science is now deciding by exact laboratory methods the
same problem as he solved by his unique knowledge of feminine
psychology.

"I saw how this case was tending. Not a moment too soon, I said to
myself, 'The hand of the child will tell.' By the very variations in
unlike things, such as finger and palm prints, as tabulated and
arranged by Bertillon after study in thousands of cases, by the very
loops, whorls, arches and composites, I have proved my case.

"The dominancy, not the identity, of heredity through the infinite
varieties of finger markings is sometimes very striking. Unique
patterns in a parent have been repeated with marvelous accuracy in the
child. I knew that negative results might prove nothing in regard to
parentage, a caution which it is important to observe. But I was
prepared to meet even that.

"I would have gone on into other studies, such as Tammasia's, of
heredity in the veining of the back of the hands; I would have measured
the hands, compared the relative proportion of the parts; I would have
studied them under the X-ray as they are being studied to-day; I would
have tried the Reichert blood crystal test which is being perfected now
so that it will tell heredity itself. There is no scientific stone I
would have left unturned until I had delved at the truth of this
riddle. Fortunately it was not necessary. Simple finger prints have
told me enough. And best of all, it has been in time to frustrate that
devilish scheme you and Veronica Haversham have been slowly unfolding."

Maudsley crumpled up, as it were, at Kennedy's denunciation. He seemed
to shrink toward the door.

"Yes," cried Kennedy, with extended forefinger, "you may go--for the
present. Don't try to run away. You're watched from this moment on."

Maudsley had retreated precipitately.

I looked at Kennedy inquiringly. What to do? It was indeed a delicate
situation, requiring the utmost care to handle. If the story had been
told to Hazleton, what might he not have already done? He must be found
first of all if we were to meet the conspiracy of these two.

Kennedy reached quickly for the telephone. "There is one stream of
scandal that can be dammed at its source," he remarked, calling a
number. "Hello. Klemm's Sanitarium? I'd like to speak with Miss
Haversham. What--gone? Disappeared? Escaped?"

He hung up the receiver and looked at me blankly. I was speechless.

A thousand ideas flew through our minds at once. Had she perceived the
import of our last visit and was she now on her way to complete her
plotted slander of Millicent Hazleton, though it pulled down on herself
in the end the whole structure?

Hastily Kennedy called Hazleton's home, Butler, and one after another
of Hazleton's favorite clubs. It was not until noon that Butler himself
found him and came with him, under protest, to the laboratory.

"What is it--what have you found?" cried Butler, his lean form a-quiver
with suppressed excitement.

Briefly, one fact after another, sparing Hazleton nothing, Kennedy
poured forth the story, how by hint and innuendo Maudsley had been
working on Millicent, undermining her, little knowing that he had
attacked in her a very tower of strength, how Veronica, infatuated by
him, had infatuated him, had led him on step by step.

Pale and agitated, with nerves unstrung by the life he had been
leading, Hazleton listened. And as Kennedy hammered one fact after
another home, he clenched his fists until the nails dug into his very
palms.

"The scoundrels," he ground out, as Kennedy finished by painting the
picture of the brave little broken-hearted woman fighting off she knew
not what, and the golden-haired, innocent baby stretching out his arms
in glee at the very chance to prove that he was what he was. "The
scoundrels--take me to Maudsley now. I must see Maudsley. Quick!"

As we pulled up before the door of the reconstructed stable-studio,
Kennedy jumped out. The door was unlocked. Up the broad flight of
stairs, Hazleton went two at a time. We followed him closely.

Lying on the divan in the room that had been the scene of so many
orgies, locked in each other's arms, were two figures--Veronica
Haversham and Dr. Maudsley.

She must have gone there directly after our visit to Dr. Klemm's, must
have been waiting for him when he returned with his story of the
exposure to answer her fears of us as Mrs. Hazleton's detectives. In a
frenzy of intoxication she must have flung her arms blindly about him
in a last wild embrace.

Hazleton looked, aghast.

He leaned over and took her arm. Before he could frame the name,
"Veronica!" he had recoiled.

The two were cold and rigid.

"An overdose of heroin this time," muttered Kennedy.

My head was in a whirl.

Hazleton stared blankly at the two figures abjectly lying before him,
as the truth burned itself indelibly into his soul. He covered his face
with his hands. And still he saw it all.

Craig said nothing. He was content to let what he had shown work in the
man's mind.

"For the sake of--that baby--would she--would she forgive?" asked
Hazleton, turning desperately toward Kennedy.

Deliberately Kennedy faced him, not as scientist and millionaire, but
as man and man.

"From my psychanalysis," he said slowly, "I should say that it IS
within your power, in time, to change those dreams."

Hazleton grasped Kennedy's hand before he knew it.

"Kennedy--home--quick. This is the first manful impulse I have had for
two years. And, Jameson--you'll tone down that part of it in the
newspapers that Junior--might read--when he grows up?"
