<h5 id="id01930">LIKE A THIEF IN THE NIGHT</h5>
<p id="id01931">From ten thousand bulbs the moving-picture houses of Curtis Street were
flinging a glow upon the packed sidewalks when Kirby came out of the
hotel and started uptown.</p>
<p id="id01932">He walked to the Wyndham, entered, and slipped up the stairs of the
rooming-house unnoticed. From the third story he ascended by a ladder
to the flat roof. He knew exactly what he had come to investigate.
From one of the windows of the fourth floor at the Paradox he had
noticed the clothes-line which stretched across the Wyndham roof from
one corner to another. He went straight to one of the posts which
supported the rope. He made a careful study of this, then walked to
the other upright support and examined the knots which held the line
fast here.</p>
<p id="id01933">"I'm some good little guesser," he murmured to himself as he turned
back to the ladder and descended to the floor below.</p>
<p id="id01934">He moved quietly along the corridor to the fire escape and stepped out
upon it. Then, very quickly and expertly, he coiled a rope which he
took from a paper parcel that had been under his arm. At one end of
the coil was a loop. He swung this lightly round his head once or
twice to feel the weight of it. The rope snaked forward and up. Its
loop dropped upon the stone abutment he had noticed when he had been
examining the exteriors of the buildings with Cole Sanborn. It
tightened when he gave a jerk.</p>
<p id="id01935">Kirby climbed over the railing and swung himself lightly out into
space. A moment, and he was swaying beside the fire escape of the
Paradox. He caught the iron rail and pulled himself to the platform.</p>
<p id="id01936">By chance the blind was down. There was no light within, but after his
eyes had become used to the darkness he tried to take a squint at the
room from the sides of the blind. The shade hung an inch or two from
the window frame, so that by holding his eye close he could get more
than a glimpse of the interior.</p>
<p id="id01937">He tapped gently on the glass. The lights inside flashed on. From one
viewpoint he could see almost half the room. He could go to the other
side of the blind and see most of the other half.</p>
<p id="id01938">A man sat down in a chair close to the opposite wall, letting his hands
fall on the arms. A girl stood in front of him and pointed a
paper-knife at his head, holding it as though it were a revolver. The
head of the man fell sideways.</p>
<p id="id01939">Kirby tapped on the window pane again. He edged up the sash and
stepped into the room.</p>
<p id="id01940">The young woman turned to him eagerly, a warm glow in her shell-pink
cheeks. "Well?" she inquired.</p>
<p id="id01941">"Worked out fine, Rose," Kirby said. "I could see the whole thing."</p>
<p id="id01942">"Still, that don't prove anything," the other man put in. He belonged
to the staff of the private detective agency with which Kirby was
dealing.</p>
<p id="id01943">The Wyoming man smiled. "It proves my theory is possible. Knowing
Olson, I'm willin' to gamble he didn't sit still on the fire escape an'
let that drawn blind shut him off from what was goin' on inside. He
was one mighty interested observer. Now he must 'a' known there was a
clothes-line on the roof. From the street you can see a washin'
hangin' out there any old time. In his place I'd 'a' bopped up to the
roof an' got that line. Which is exactly what he did, I'll bet. The
line had been tied to the posts with a lot of knots. He hadn't time to
untie it. So he cut the rope. It's been spliced out since by a piece
of rope of a different kind."</p>
<p id="id01944">"How do you know that's been done since?" the detective asked.</p>
<p id="id01945">"A fair question," Kirby nodded. "I don't. I'll find out about that
when I talk with the landlady of the Wyndham. If I'm right you can bet
that cut rope has puzzled her some. She can't figure out why any one
would cut her rope down an' then leave it there."</p>
<p id="id01946">"If you can show me her rope was cut that night, I'll say you're
right," the detective admitted. "And if you are right, then the Swede
must 'a' been right here when your uncle was killed."</p>
<p id="id01947">"<i>May</i> have been," Kirby corrected. "We haven't any authentic evidence
yet as to exactly when my uncle was killed. We're gettin' the time
narrowed down. It was between 9.30 and 9.50. We know that."</p>
<p id="id01948">"How do you know that?" the professional sleuth asked. "Accordin' to
your story you didn't get into the apartment until after ten o'clock.
It might 'a' been done any time up till then."</p>
<p id="id01949">The eyes of Kirby and Rose met. They had private information about who
was in the rooms from about 9.55 till 10.10.</p>
<p id="id01950">The cattleman corrected his statement. "All right, say between 9.30
and 10.05. During that time Hull may have shot my uncle. Or Olson may
have opened the window while my uncle lay there helpless, killed him,
stepped outa the window again, an' slipped down by the fire escape.
All he'd have to do then would be to walk into the Wyndham, replace the
rope on the roof, an' next mornin' leave for Dry Valley."</p>
<p id="id01951">The detective nodded. "<i>If</i> he cut the rope. Lemme find out from the
landlady whether it <i>was</i> cut that night."</p>
<p id="id01952">"Good. We'll wait for you at the corner."</p>
<p id="id01953">Ten minutes later the detective joined them in front of the drug-store
where they were standing. The hard eyes in his cold gambler's face
were lit up for once.</p>
<p id="id01954">"I'll say the man from Missouri has been shown," he said. "I let on to
the dame at the Wyndham that I was after a gang of young sneak thieves
in the neighborhood. Pretty soon I drifted her to the night of the
twenty-third—said they 'd been especially active that night and had
used a rope to get into a second story of a building. She woke up.
Her clothesline on the roof had been cut that very night. She
remembered the night on account of its being the one when Mr.
Cunningham was killed. Could the boys have used it to get into the
store an' then brought it back? I thought likely."</p>
<p id="id01955">"Bully! We're one step nearer than we were. We know Olson was lookin'
in the window from the fire escape just outside."</p>
<p id="id01956">The detective slapped his thigh. "It lies between Hull and the Swede.<br/>
That's a cinch."<br/></p>
<p id="id01957">"I believe it does," agreed Rose.</p>
<p id="id01958">Kirby made no comment. He seemed to be absorbed in speculations of his
own. The detective was reasoning from a very partial knowledge of the
facts. He knew nothing about the relations of James Cunningham to his
uncle, nor even that the younger Cunninghams—or at least one of
them—had been in his uncle's apartment the evening of his death. He
did not know that Rose had been there. Wherefore his deductions, even
though they had the benefit of being trained ones, were of slight value
in this case.</p>
<p id="id01959">"Will you take the key back to the Chief of Police?" Kirby asked him as
they separated. "Better not tell him who was with you or what we were
doin'."</p>
<p id="id01960">"I'm liable to tell him a whole lot," the detective answered with heavy
irony. "I'm figurin' on runnin' down this murderer myself if any one
asks you."</p>
<p id="id01961">"Wish you luck," Kirby said with perfect gravity.</p>
