<h2 id="XXIII">CHAPTER XXIII. <br/> <small>THE HYPODERMIC.</small></h2>
<p>The detective’s scheme was simplicity itself, and
it promised success. He had merely instructed Stickney
to have Stone’s bell rung at the appointed time, and
to keep it ringing continuously until the miner should
leave his room in desperation to complain of the nuisance.</p>
<p>If it worked out as Nick hoped, Stone’s absence
would give him the opportunity he sought, and meanwhile
the miner would be informed that the electrical
apparatus must have been deranged in some way. It
would be looked to and “remedied;” whereupon, the
ringing would cease, and Stone would receive the
apologies of the management.</p>
<p>Nick assumed, however, that the miner would first
telephone downstairs. The din would make it difficult
for him to be understood, though; and even if he
were, he would doubtless grow impatient at the delay
and soon leave his room to complain in person
to the clerk.</p>
<p>The fact that he was already dressed would make
that easy, and Nick counted on his doing so sooner
or later. At any rate, he had arranged with Stickney
that the bell should continue its exasperating dinning
if possible until Stone had been routed out.</p>
<p>On the other hand, there was a possibility, of course,
that the man would not act in accordance with expectations.<span class="pagenum"><SPAN name="Page_113" id="Page_113">[113]</SPAN></span>
He might remain at the telephone, or
even demolish the bell in his anger, especially as he
would doubtless be afraid that it would arouse Crawford,
and that the latter might not fall asleep again
for some time. Nick had to run that risk, though;
and now he was impatiently awaiting some sign that
his ruse was working as he wished.</p>
<p>The muffled ringing of the bell prevented him from
telling whether Stone was telephoning or not, but he
had no doubt that such was the case. Would the
man stop at that, though?</p>
<p>Evidently not; for two or three minutes after the
bell began to ring he caught the sound of an opening
door, despite the racket, and almost immediately afterward
hurried footsteps passed his room.</p>
<p>He waited for nothing more, but crawled through
his window near to the neighboring platform of the
fire escape and laid hands on Stone’s sash. It came
up easily, and revealed an empty room, and the door
ajar. It was a risky undertaking, and one that was
full of uncertainties. The irate miner might return
at any moment. Crawford might come in from the
adjoining room and denounce him as a suspicious
character, or some one else might put in an appearance
to investigate the noise which must have been
disturbing many by that time. Worst of all, Stone
had left the door partly open and the light on, so
that Nick had to work in the open, with a possibility
of being seen and interrupted at any moment.</p>
<p>None of these things seemed to worry him, though.
He slipped cautiously into the room and looked about<span class="pagenum"><SPAN name="Page_114" id="Page_114">[114]</SPAN></span>
him with keen eyes. A faint ejaculation of satisfaction
escaped his lips as he caught sight of what
he was looking for.</p>
<p>There was a small writing desk close to the head
of the bed. It was open, and on the extended leaf
lay a small, flat, leather case. Leaping forward, Nick
opened the case and took out a small hypodermic
syringe. The plunger had been drawn back to its
fullest extent, and the detective’s lips tightened as he
realized that in that little cylinder lurked sure death.</p>
<p>He paid no attention to the other articles in the
case—the tiny bottle with some colorless drug, the
bit of sponge, and so on. He cared nothing for them,
and was interested only in the deadly hypodermic.</p>
<p>Looking about him again, and listening all the
while, he took out his fountain pen, removed the cap,
and unscrewed the pen itself; then he squirted the
contents of the syringe into the barrel of the pen,
which he had taken the precaution to empty before
leaving his room, and replaced the pen and cap.</p>
<p>Having finished that manipulation, he carelessly
thrust the pen back into his pocket and went with
long, silent strides to a stationary washstand in a little
alcove. He turned on the faucets, directed a little
stream of warm water into the syringe, and operated
the plunger several times, in order to clean the cylinder
as well as he could; after which he filled the
syringe with water, and, leaving the plunger out as
he had found it, returned the instrument to the case.
The case closed, he made for the window.</p>
<p>So swift had been his movements that he had been<span class="pagenum"><SPAN name="Page_115" id="Page_115">[115]</SPAN></span>
in the room hardly more than a minute, and nothing
had occurred to disturb him. The bell had continued
its deafening ringing, and he had thought he heard
Crawford’s bed creak, but Stone’s partner had not
called out. He gave a sigh of relief as he reached
the balcony of the fire escape and plunged out into
the shadows at one side. In a few brief moments
he was over the railing and through his own window.</p>
<p>He had hardly reached his room, however, before
he heard Stone’s familiar footsteps in the corridor
outside. The miner was returning, and muttering
angrily to himself as he did so. Presently the noise
ceased. The bell had been “fixed.” The detective
heard Stone pass again and yet again, probably to
tell the floor clerk that it was all right.</p>
<p>Not until Stone’s door was finally closed and locked
did the detective drop into a chair. “Whew!” he
said, half aloud, “that was warm work, and not very
good for the nerves. I’ve saved Crawford for the
time being, but my work isn’t done by any means—even
for to-night.”</p>
<p>He looked at his watch and found that it was
quarter past one. There was still an hour and a
quarter if Stone obeyed instructions, and Nick had
no doubt that he would now. In fact, he might even
wait longer, for he would be certain to fear that the
ringing of the bell had disturbed Crawford, and would
wish to give him plenty of time to fall into a deep
sleep again.</p>
<p>Nick did not intend to remain idle, but he felt sure
that he had some time to kill, and he was glad of it.<span class="pagenum"><SPAN name="Page_116" id="Page_116">[116]</SPAN></span>
Despite his iron nerve, he felt just a trifle shaken by
the exacting ordeal through which he had just gone;
therefore, he took out a cigar, lighted it, and leaned
back in a Morris chair. He must have dozed off
before long, for the next thing he knew he sat up
with a start. It was half past two.</p>
<p>“Stone will probably be making a move now,” he
thought, on the alert at once. “I’m glad my mental
alarm clock woke me when it did.”</p>
