<p>Nick Carter wore a worried look at eight o’clock
that evening. Both he and Chick then were dressing
for the elaborate reception and ball tendered to
the local National Guards, generally admitted to be
the chief social event slated for that season in Madison,
and during which the unknown crook whom the
detectives were so anxious to identify had threatened
to commit the crime the latter were grimly determined
to prevent.</p>
<p>Nick Carter’s anxiety, however, was not because
his life also had been threatened and might possibly
be taken, in case he became an insurmountable obstacle
to the designs of the mysterious and daring desperado.
He was thinking of Patsy Garvan, his prolonged absence,
the occasion for which he could not fathom,
knowing that Patsy ordinarily would have reported
by telephone, at least, in view of the work engaging
him, unless something very unexpected and equally
serious prevented him.</p>
<p>The detective did not blind himself, moreover, to
the fact that his own designs had been repeatedly anticipated
and balked by the unknown knave or by
members of his gang, in spite of his own expeditious
work and the precautions he had taken. He realized
most keenly that he was up against a remarkably
crafty and resourceful scoundrel. He began to fear
that Patsy had fallen into his hands and, in spite of<span class="pagenum">[188]</span>
his confidence in his own skill and prowess, that he
also might be booked for failure and utterly unable
to prevent the threatened theft of Mrs. Mortimer
Thurlow’s pearls.</p>
<p>“It would be perfectly easy to foil the rascals, if that
was all we wished to accomplish,” said the detective,
while he and Chick were discussing their plans. “But
that is not enough.”</p>
<p>“Certainly not,” declared Chick. “We must take
advantage of the circumstances to discover their identity
and in some way contrive to arrest them.”</p>
<p>“Exactly. We must allow them enough leeway,
therefore, to be sure they will attempt the crime,”
Carter pointed out. “They know what they are up
against and that we are out to get them. If we remain
too near to Mrs. Thurlow, as if ready to instantly
grab any one that lays a finger on her, there
will be nothing to it. The miscreants will throw
up the job.”</p>
<p>“Surely,” Chick agreed. “No sane man would
attempt it under such conditions.”</p>
<p>“The fact that we are carefully disguised, moreover,
would not deceive them. They would suspect
any men who constantly hung around within reach
of Mrs. Thurlow, and would very soon identify us.
We must give them enough leeway, therefore, as I
have said, to be sure they will make the attempt.”</p>
<p>“I agree with you,” Chick nodded.</p>
<p>“It goes without saying, nevertheless, that we must
be in a position to constantly watch the woman,” Carter
added. “Having no idea just when the theft may
be attempted, we must not lose sight of her for a moment.”</p>
<p><span class="pagenum">[189]</span></p>
<p>“What plan had we better adopt?”</p>
<p>“We can lay no elaborate plan. It will be of advantage,
however, if we keep an eye on one another,
as well as on the woman, and contrive to keep her constantly
between us. That will enable us to head off
a thief in two directions, at least.”</p>
<p>“I see the point.”</p>
<p>“We must be alert, also, to detect any person whose
looks or actions warrant suspicion,” Carter continued.
“It is barely possible that one of us can discover the
crook before the theft is attempted.”</p>
<p>“I’ll put you wise, chief, in that case, and you do
the same.”</p>
<p>“Yes, of course.”</p>
<p>“Her nephew is to be her escort, you say.”</p>
<p>“Yes. His name is Dorson. He will accompany
both Mrs. Thurlow and her daughter, and we can
identify them when they arrive.”</p>
<p>“And our work must begin at that moment.”</p>
<p>“Exactly. Naturally, of course, Dorson will pay
considerable attention to Mrs. Thurlow, and I don’t
think his presence will deter the crooks, for I have
directed her to say nothing to him about expecting a
crime. There is no occasion for any one to suspect
him, of course, even though he is with her much of
the time.”</p>
<p>The detective added the last while they were about
to leave. It was a perfectly natural supposition, of
course, that the man of whom he was speaking was
entirely trustworthy. He did not have a thought to
the contrary, and, therefore, he could not foresee the
fatal result of this misplaced confidence in Mr. John
Dorson.</p>
<p><span class="pagenum">[190]</span></p>
<p>It was a brilliant scene upon which the two detectives
arrived soon after eight o’clock, which they knew
would be sufficiently early. The streets adjoining
the park in which the handsome new armory building
was situated, in the vast hall and drill room, on the
second floor of which the ball was to be held, were
crowded with costly, brightly lighted automobiles of
nearly every type, leaving as rapidly as possible a
throng of fashionably clad men and elaborately
gowned women, many lavishly adorned with radiant
gems and jewels.</p>
<p>Fortune favored the detectives at first. They had
been waiting only a few minutes in the broad reception
hall on the ground floor, when Carter saw Mrs.
Thurlow and Edna arrive in company with a tall,
somewhat cadaverous man, who he knew must be Mr.
John Dorson.</p>
<p>“There they are, Chick,” he said quietly. “The
woman has not weakened. She is doing her part,
indeed, to help us nail our man. She is wearing the
rope of pearls.”</p>
<p>“Some pearls, too,” Chick muttered admiringly.
“By Jove! they warrant taking a desperate chance.
That tall fellow is Dorson, I suppose.”</p>
<p>“Surely.”</p>
<p>“He’s not very attractive. He has the look of a
rounder.”</p>
<p>“Not as bad as that, I guess,” said Carter. “I think
Mrs. Thurlow would have told me. Step down that
way and keep an eye on her. We now must watch
her constantly.”</p>
<p>Both had been standing in an alcove formed by the rise
of the broad, main stairway. The latter led up<span class="pagenum">[191]</span>
to a wide corridor flanking three sides of the ballroom,
which was accessible from each through several broad,
pillared doorways. In the end wall of the room was
a row of open French windows, leading out upon the
balcony roof of a wide veranda overlooking an avenue
through the park mentioned, in which numerous automobiles
already had gathered to await the end of the
festivities.</p>
<p>One among them had arrived quite early and obtained
a position of special advantage, close to the
broad avenue and within easy view of the veranda and
balcony. It attracted no more attention than any of
the others, neither did the chauffeur, who sat motionless
at his wheel. None would have recognized his
bearded face, nor could the car have been traced from
the license number it then appeared to bear.</p>
<p>It was to these conditions and surroundings that
Professor Karl Graff had referred while talking with
Dorson in the road house, and of which he and his
knavish confederates were prepared to take every
advantage.</p>
<p>Chick slipped away from his chief, as the latter had
directed, and took a position from which he could
watch the door of a room to which Mrs. Thurlow
and Edna had gone to leave their outside garments,
while Dorson hastened to another to check his crush
hat and Inverness. Though his face was unusually
pale and grave, it wore no expression inviting suspicion.</p>
<p>He returned in a few moments and rejoined Edna
Thurlow, departing with her through the throng in
the lower corridor and mingling with the stream of
wealth and fashion then seeking the ballroom.</p>
<p><span class="pagenum">[192]</span></p>
<p>Mrs. Thurlow came out a little later and joined a
group of women acting as a reception committee, and
for nearly an hour she remained in the lower hall,
apparently undisturbed by the threats of which she
had been informed, and conducting herself precisely as
if ignorant of them, as Carter had directed.</p>
<p>Both detectives, though they then were separated,
had an eye on her all the while and on the rope of lustrous
pearls adorning her shapely neck and perfect
shoulders. Neither could detect any person near her
inviting suspicion, however, and it really seemed improbable
that so daring a theft could be successfully
committed, in view of the fact that it had been predicted
and prevention audaciously invited.</p>
<p>It was ten o’clock when Mrs. Thurlow went up to
the lavishly decorated ballroom. There, and in the
adjoining corridors, a throng of several hundred
guests were assembled. A dance then was in progress,
however, and the corridors were less crowded than
during the intervals between the dances.</p>
<p>Carter and Chick met on the stairs while following
the woman quite closely, and Carter said a bit hurriedly,
noting the direction she was taking:</p>
<p>“She’s going to that end of the hall overlooking the
balcony. I’ll follow her. You hurry around through
the corridor, so as to watch her from the opposite
side of the hall. We then will have her guarded from
both directions.”</p>
<p>“Suppose she goes out on the balcony?”</p>
<p>“Slip out through one of the other windows. You
must not lose sight of her.”</p>
<p>“I’ve got you,” Chick muttered, as he turned at
the head of the stairs and hurried away.</p>
<p><span class="pagenum">[193]</span></p>
<p>Carter followed the woman in the opposite direction,
admiring her outward composure and the nerve
she was displaying. He saw her enter the last of the
broad doors and thread her way by the throng of
dancers, finally halting near one of the windows leading
out to the balcony, where she was immediately
joined by a colonel of the Guards, in full-dress uniform,
and a lady, with whom he had been dancing.</p>
<p>Carter paused in the broad doorway, with a quick
and searching glance in each direction. He caught
sight of Chick, just entering a door directly across the
broad, brightly lighted hall. He saw Edna Thurlow
amid the throng of dancers, and noticed that she was
pale and paying little attention to the remarks of her
partner. He saw, too, the tall form of Mr. John
Dorson, who then was standing alone near the second
window beyond that near which Mrs. Thurlow had
halted.</p>
<p>Though none could know it save the miscreant who
had planned the daring job, the situation then was
one for which he had been waiting, the crucial moment
when conditions assured him of success, when
the avenue fronting the veranda was unobstructed,
when flight would be easy, when the throng in the
ballroom were absorbed in the dance, when the strains
of orchestral music drowned all other sounds, and
when the victim of his designs had paused at a time
and place that perfectly served his purpose.</p>
<p>Two inconspicuous, bearded men in evening dress,
who had apparently been talking carelessly on the balcony,
suddenly separated.</p>
<p>One of them glided quickly toward the window<span class="pagenum">[194]</span>
near which Mrs. Thurlow was standing, taking a position
close against the wall.</p>
<p>The other moved in the opposite direction, stopping
short near the second window and taking a small
electric flash light from his pocket. Hooding it with
both hands, so that its glare might not be observed
by any of the persons then on the balcony, he lighted
the lens for a moment, so holding it that it could be
seen from the grounds, on which motionless motor
cars then were parked.</p>
<p>The signal was answered almost instantly. The
lamps of one of the motionless motor cars shot a
quick glare outward over the avenue, and in another
moment it was moving moderately in that direction.</p>
<p>The man with a searchlight turned quickly and entered
the French window. He passed directly back of
Dorson, and, without stopping, whispered hurriedly:</p>
<p>“Now, Dorson, be quick! Get in your work!”</p>
<p>Dorson started as if stung. He did not recognize
the bearded man, but there was no mistaking his voice,
that fierce, sibilant hiss that he had heard at the road
house—the threatening voice of Professor Karl Graff.</p>
<p>Dorson instantly pulled himself together, nevertheless,
and nerved himself for what he had undertaken.
He took the celluloid box from his pocket,
concealing it in his hand, and removed the cover, at
the same time walking toward Mrs. Thurlow, at whom
he had been gazing when he heard Graff’s threatening
command.</p>
<p>When nearly back of her, Dorson stooped to the
floor and pretended to pick up a handkerchief—which
he had deftly removed from the box, quickly replacing
the latter in his pocket.</p>
<p><span class="pagenum">[195]</span></p>
<p>“Pardon me,” said he, stepping in front of her.
“You have dropped your handkerchief, Aunt Clara.”</p>
<p>The colonel talking with her turned at once to his
partner, and they whirled away amid other dancing
couples.</p>
<p>“My handkerchief, Jack?” Mrs. Thurlow took it, but
with a look of surprise.</p>
<p>“I think so.” Dorson drew back a step and with
one hand covered his mouth and nostrils.</p>
<p>“No, this is not mine. You are mistaken.”</p>
<p>“Are you sure, Aunt Clara? It was on the floor
behind you. I thought you had dropped it.”</p>
<p>Mrs. Thurlow bowed her head a little closer to examine
it, still much crumpled, unfolding it and seeking
an initial.</p>
<p>“No, it is not mine, Jack,” she repeated. “It may
be marked, however, or—or——”</p>
<p>Her voice suddenly died away to a whisper. She
looked up at Dorson, as if strangely dazed, and he
saw her eyes quickly taking on the vacant expression
that had been predicted, the pupils contracting to mere
pinpoints, abnormally bright, while her lips turned
from red to a dull gray.</p>
<p>Though his every nerve was quivering with secret
terror, Dorson kept his head and continued to play his
part. He instantly took the woman’s arm, saying
quietly:</p>
<p>“You are pale and look tired. Step out on the balcony
with me. The air will revive you.”</p>
<p>Mrs. Thurlow obeyed him as if in a trance or a victim
of an hypnotic spell. She walked out with him
through the French window. There was a large
wicker chair near by, and Dorson placed her in it, then<span class="pagenum">[196]</span>
whisked the fateful handkerchief from her fingers and
thrust it into his pocket. Then he hurried back into
the ballroom, through which he passed as if in haste
to obtain water, as he really was.</p>
<p>The man lurking near the wall in the dim light
instantly approached the woman. Pausing beside her
chair, he bowed as if to converse with her. His keen,
black eyes shot one swift glance at a few persons on
a remote part of the balcony. None was observing
him. His deft hands quickly lifted the rope of pearls
and dropped it into his pocket. Then he took out a
small glass vial, poured the contents of it upon a
sponge, and held the latter to the woman’s nostrils for
a few seconds.</p>
<p>Mrs. Thurlow gasped and caught her breath.</p>
<p>The man accidentally dropped the vial and it rolled
out of sight. He did not wait to search for it, did not
dare to delay his departure. He walked quickly toward
a corner of the balcony, where the top of a vine-covered
trellis rose just above the railing.</p>
<p>Toby Monk was at that moment passing the corner
with his motor car.</p>
<p>Both Nick Carter and Chick had witnessed the episode
in the ballroom, and the same thought arose in
the minds of both—that Mrs. Thurlow was perfectly
safe while with her nephew.</p>
<p>The moment that Dorson returned alone, however,
both detectives felt a quick thrill of suspicion, an instinctive
feeling that the fateful moment had arrived,
and both hurried toward the nearest of the French
windows, making their way as quickly as possible
through the maze of whirling dancers.</p>
<p>Chick was the first to reach the balcony. Coming<span class="pagenum">[197]</span>
from the glare in the ballroom, he could not immediately
see the seated woman in the dim light outside.
He discovered her in a moment, however, and ran toward
her—just as his chief hurriedly approached from
the opposite direction.</p>
<p>One glance at Mrs. Thurlow’s white face, at her vacant
eyes and lax figure, at the neck, then bare of its
lustrous adornment—one glance was enough.</p>
<p>“By thunder, they’ve turned the trick!” Chick cried,
staring. “That man Dorson must——”</p>
<p>Carter did not wait to hear him. He had swung
around like a flash, seeking the thief, knowing that
scarce a minute had passed since the woman left the
ballroom. The few persons then on the balcony had
not observed any disturbance, but the detective instantly
caught sight of the swaying top of the trellis
mentioned.</p>
<p>He ran in that direction, reaching for his revolver,
but he arrived at the corner of the balcony rail only
in time to see a slender, black-clad figure leap into
a moving motor car, that instantly sped away down
the avenue—Tim Hurst, with the rope of pearls in his
pocket.</p>
