<h2 id="XXI">CHAPTER XXI. <br/> <small>IN NEED OF EVIDENCE.</small></h2>
<p>Nick Carter moved with the quickness of a cat.
In a twinkling he had jerked the ear piece away and
slipped it into his pocket. While doing so, he had
straightened up noiselessly and started along the platform
of the fire escape in the direction of his own
window.</p>
<p>It was a close shave. Follansbee had started to
raise the shade before Nick even reached the railing
over which he had to climb, and while he was crawling
over the barrier the sash of Stone’s window was being
lifted.</p>
<p>Fortunately for him, however, Follansbee tried to
make as little noise as possible, consequently his movements
were slower than they otherwise would have
been. For all that, though, the detective was not out
of sight by the time Follansbee stuck his head and
shoulders through the opening.</p>
<p>It was a tense moment, and Nick’s heart skipped a
beat or two. Should Follansbee happen to glance
that way the first thing and catch a glimpse of his
feet disappearing through the window the consequences
would be disastrous.</p>
<p>Despite the temptation to do so, he did not forget
his caution for a moment, or allow his extreme haste<span class="pagenum"><SPAN name="Page_104" id="Page_104">[104]</SPAN></span>
to betray him into a clumsy move. He slipped from
view almost noiselessly, and tiptoed away from his
window into the shadows of his room.</p>
<p>All the time he was listening intently for some evidence
that Follansbee had seen him, but none came.
Seemingly the physician continued to climb through
Stone’s window, and, having done so, proceeded on
his stealthy way down the fire escape.</p>
<p>The detective heard a slight sound, followed by the
grating of the sash. Evidently the ex-miner had
again closed the window.</p>
<p>As soon as Nick dared, he ventured back and stealthily
peered over his own sill. Follansbee was then
descending the painter’s ladder. And when the bottom
was reached, he lifted the ladder carefully away
from the lower platform of the fire escape and carried
it, with considerable difficulty, back to the place
from which it had been taken.</p>
<p>Subsequently his figure vanished, going in the direction
of the open end of the court.</p>
<p>“The end of the first act,” thought Nick, “and the
play promises to be a hair-raiser.”</p>
<p>With his brows drawn together and his arms folded
across his breast, he paced softly up and down his
room, turning his discoveries over and over in his mind.
He had heard enough to realize that Crawford was
in deadly peril. With his usual cunning, Stephen
Follansbee had again taken what promised to be a
perfectly, safe course. To the specialist’s crooked
brain, there could be no possible chance of fixing the<span class="pagenum"><SPAN name="Page_105" id="Page_105">[105]</SPAN></span>
contemplated crime on him, if it was Stone, the tool,
who was playing the principal part.</p>
<p>To be sure, Nick had overheard a conversation
which left him in no doubt as to where the real responsibility
lay. He had heard Follansbee say that
as a result of the proposed measures, Crawford would
be dead before the twenty-seventh. To the uninitiated,
that would have seemed conclusive, and more
than enough to convict the physician. Nick Carter
knew better, however; at any rate, he knew enough
to be sure that Follansbee would make a great fight
if the case ever came to trial, and might easily wriggle
out of it.</p>
<p>In the first place, he was a distinguished man, a leading
light in his profession, and the ruling spirit of a
great hospital. Nick was the only witness, and it
would be very hard, if not impossible, for the detective,
with all his reputation, to convince a jury on the
strength of such evidence alone that Doctor Stephen
Follansbee would stoop to become the accessory to a
murder.</p>
<p>Follansbee would have the advantage of dealing
with a demented man, and could insist that everything
which seemed suspicious about his actions—the use
of the fire escape and all—had been due to that fact.
In other words, he might build up a plausible excuse
on the theory that he had been humoring Stone in
order to study his case, and to see how far the miner’s
insanity would carry him.</p>
<p>“It must be the germ of some deadly disease, characteristic
of the tropics,” Nick told himself, “and he<span class="pagenum"><SPAN name="Page_106" id="Page_106">[106]</SPAN></span>
has left the hypodermic syringe there for Stone to
use. That’s as plain as the nose on my face. But
without more evidence than I now have, I can’t be
sure of securing a conviction. Follansbee is as
shrewd as they make them. I wouldn’t be a bit surprised
to have him claim that the contents of the
syringe were harmless, and that he was merely ‘stringing’
Stone for some medical reason. What he said
about Crawford’s death could always be attributed to
the same motive, and his reputation is so great that
it would probably hypnotize a jury into accepting his
word for it. He’s a cunning rascal, and no mistake.
How am I going to manage this affair? I’ve got to
do something before two-thirty, but what?”</p>
<p>It was seldom that Nick Carter felt at a loss, yet
he realized that his position was a peculiarly difficult
one. He might have forced his way into James Stone’s
room, of course, but he felt that the mine owner
would have sufficient cunning to destroy at once the
only tangible evidence of guilt as soon as he heard
the first alarm. And even if he did foil Stone’s attempt
that night, the detective feared that it would
only be putting off the evil day. He could have Stone
locked up, to be sure, and an inquiry into his sanity
begun. He might also be able to secure Follansbee’s
arrest.</p>
<p>That would seem to clear the way and remove
Crawford’s danger; but the detective saw further than
that. He felt certain that Follansbee must have demanded
a large fee of Stone, either for treatment or
frankly for the services of getting rid of the man’s<span class="pagenum"><SPAN name="Page_107" id="Page_107">[107]</SPAN></span>
partner. Furthermore, he was assured that Follansbee
had contrived it so that the fee would be paid
whatever happened.</p>
<p>In that case the arrest or death would by no means
end the matter. Follansbee’s professional standing
would undoubtedly result in an arrangement whereby
the specialist would go free under heavy bonds pending
his trial, and the moment he was at liberty to
do so, he would almost certainly begin work on a new
attempt to get rid of Winthrop Crawford and to
earn his money.</p>
<p>That fact had to be taken into consideration in
connection with Follansbee, for the latter would not
be treated as an ordinary criminal; therefore, it became
increasingly evident that Nick would have to
meet cunning with cunning if he hoped to handle
the affair successfully.</p>
<p>At last, the hint of a plan came to him. He halted
by his window and looked out again. The light was
still shining in Stone’s room. “I must go in there
without the fellow’s knowledge,” he thought. “A
minute, possibly half a minute, would do, with good
luck. I wonder how I can manage it, though?”</p>
