<p>The trail picked up by Patsy Garvan was becoming
so hot, indeed, as he had expressed it, that he now
had absolutely no idea of quitting it. He followed
the two suspects through Prince Street, noting that
they were engaged in a subdued and very earnest discussion,
with Shannon doing most of the talking, but
Patsy did not venture to attempt overhearing them.</p>
<p>“I could pick up only a word or two at the most, and
must take a chance of being seen and suspected,” he
rightly reasoned. “That would put them on their
guard and knock a further espionage on the head. I’d
better keep them in the dark and try to see what’s
coming off. If Shannon brought orders from some
one to this sinister-looking scamp, it’s long odds that
Doctor Devoll was the one. There sure is something
in the wind.”</p>
<p>It soon was evident to him that the two men were
heading for the stable in which Toby Monk kept his
car, and he began to fear that he was booked for
the same difficulties he had had the previous night.
He felt quite sure of it, in fact, when both men entered
the stable and Toby Monk partly closed the
front door, precluding a view from the street.</p>
<p>Presently, however, a feeble light from a smoky lantern
could be seen, and Patsy muttered perplexedly:</p>
<p>“What do they want of that? They can’t be going
out with the car, after all, or a lantern would not<span class="pagenum">[177]</span>
be needed. They may have come here only to escape
observation while planning a job. I can very soon
find out by making use of the back window again.”</p>
<p>He was on his way with the last thought. A couple
of minutes brought him to the back fence, over
which he climbed noiselessly, and then crept near
enough to see and hear through the dusty back window.</p>
<p>Toby Monk was on his knees with a box of blue
paste and a brush, engaged in altering the figures on
the rear number plate of the touring car.</p>
<p>Shannon was seated on a box near by, with his
brawny arms resting on his knees, while he grimly
watched the chauffeur’s artistic alterations.</p>
<p>“You’d better let the top down, too, Toby,” he advised,
after a moment. “That will help.”</p>
<p>“Mebbe so, Jim, since I’m never seen with it down,”
Monk replied. “I’ll drop it before leaving.”</p>
<p>“Besides, it might be a bit in the way,” Shannon
pointedly added. “It’s easier to get into an open
car. This trick has got to be turned on the jump, mind
you.”</p>
<p>“I know that, Jim, all right, and you can bet I’ll
do my part.”</p>
<p>“Have I made it perfectly plain to you?”</p>
<p>“As plain as twice two.”</p>
<p>“The signal——”</p>
<p>“There’s no need to repeat it, Jim,” Toby protested,
interrupting, much to Patsy’s disappointment. “I’ve
got the whole business down pat, so far as my part
in the job goes. You may tell his nibs he may bank
on that.”</p>
<p>“The hour——”</p>
<p><span class="pagenum">[178]</span></p>
<p>“I know,” Monk again cut in impatiently. “You
need never repeat an order that he sends me. There’s
too much coming, Jim, for me to go lame.”</p>
<p>“I’ll be off, then, Toby, and tell him I found you,”
said Shannon, rising abruptly. “He’ll be waiting for
me by this time.”</p>
<p>“Go ahead, then, and I’ll see you later.”</p>
<p>“Sure thing, Toby, bar a slip-up of some kind,”
Shannon paused to add. “You know what we are
up against.”</p>
<p>“Rats! Trust his nibs to get the best of that bunch.
No dicks can fool him. He’ll put something over on
them that they never heard of.”</p>
<p>Shannon laughed grimly, picking his way around
the touring car, and left the dingy, dimly lighted stable.</p>
<p>Patsy Garvan hesitated only for a moment. He remembered
the previous night. He knew that he might
find it utterly impossible to follow Toby Monk, who
evidently was soon going to use his car, and Patsy
immediately stole around the stable, taking advantage
of the darkness to dart back of the rear dwelling,
and in another moment he was stealthily following
Shannon up the street.</p>
<p>“Going to tell his nibs, is he?” thought Patsy, with
ever-increasing elation. “If I don’t learn who is back
of this whole business, then there’ll be something
wrong with the cards. Get the best of the chief, will
he? I guess not!”</p>
<p>He found it easy to shadow his unsuspecting
quarry. He trailed him to an outskirt of the business
section, where Shannon paused briefly in a gloomy
doorway and put on a disguise. Five minutes later,<span class="pagenum">[179]</span>
after looking sharply in each direction, he entered a
court flanking one end of a large stone building.</p>
<p>“By gracious!” thought Patsy, gazing up at it.
“This is the Waldmere Chambers, the building in
which Todd was killed. Has the gang a headquarters
here, or is it where only the chief himself hangs
out? In either case, by Jove! I’m getting in right at
last.”</p>
<p>Stealing nearer, he peered cautiously into the court.
Shannon had disappeared in the deeper darkness. Following
noiselessly, Patsy brought up at a solid wooden
gate about six feet high, and he then heard a door
closed and the snap of a lock. It told him plainly
enough that Doctor David Devoll’s burly attendant
had entered the building.</p>
<p>“Gee whiz! I must not lose track of him,” Patsy
muttered under his breath. “I’ll take chances to guard
against that. Locked, by thunder!”</p>
<p>Patsy had vainly tried to open the gate. He saw
that it closed an alley about five feet wide between
the rear of the Waldmere Chambers and the blank back
wall of another lofty building. He drew himself up
and looked over it. He could see a door some ten
feet away, and directly above it a single-lighted window,
the roller shade of which was drawn nearly to
the sill.</p>
<p>“That’s a rear office on the second floor,” Patsy
rightly reasoned. “That door must open into a basement,
however, for the land slopes toward the front
of the building. By Jove! I must find out what’s doing.”</p>
<p>Without a sound that could have been heard in
the office mentioned, he climbed over the gate and<span class="pagenum">[180]</span>
dropped upon the pavement in the alley, then picked
his way through the gloom toward the door. He
then found that it was an ordinary storm door, opening
outward and protecting an interior one, which
was securely locked.</p>
<p>He listened vainly for any sound from within, also
at two ground-glass windows near by, evidently those
of a basement, then as dark as a pocket. Both were
securely fastened.</p>
<p>“Gee! I’m no better off,” he said to himself. “If
I could get up to that lighted window, I might learn
whether Shannon is there, or—by gum! I have it. I
can both see and hear, all right, by standing on the
top of this outer door. It’s some stunt to get up there,
though, without being heard.”</p>
<p>He demurred only briefly, seeing no other way to
accomplish his object. He opened the door, then hung
by his hands from the top for a moment, finding that
the hinges would support him. He then drew himself
up, working one leg over the outer corner, and
finally worming himself to a seat on the unsteady
perch. Twice he had swung against the building, but
met the wall noiselessly with his shoulder.</p>
<p>Reaching up, he then could grasp the stone sill of
the lighted window. He drew himself up, hanging
clear of the door, then nearly closed it with his feet,
bringing it to a position directly under the window,
enabling him to stand in a crouching posture on it,
still grasping the stone sill.</p>
<p>A beam of light from under the roller shade then
fell on Patsy’s grimly determined face. Voices from
within reached his ears. He peered into the room and<span class="pagenum">[181]</span>
saw, seated in opposite chairs, Jim Shannon and Professor
Karl Graff.</p>
<p>“The man I trailed to Leary’s road house! The
man who killed the cat!” The thoughts flashed
swiftly through Patsy’s mind. “By gracious, it now
is a cinch! He’s the big finger of the gang. But who
the deuce is he?”</p>
<p>Though puzzled as to his identity, Patsy read plainly
in Professor Graff’s gray-bearded face that he was
discussing something of serious importance. His narrow
eyes had a vicious gleam and glitter. He was
drawn forward in his chair, with his hands clenched
on his knees and his gaze riveted on Shannon’s dark
face, from which he had removed his disguise.</p>
<p>“You made it clear to him, Jim, perfectly clear?”
Graff was asking. “There must be no mistake, no
delay.”</p>
<p>“There’ll be none,” Shannon gruffly informed him.
“You can bank on that.”</p>
<p>“The number plates——”</p>
<p>“I left him changing them.”</p>
<p>“The position he is to take with the car——”</p>
<p>“He knows the very spot.”</p>
<p>“The signal——”</p>
<p>“Your flash light—he knows,” Shannon cut in
again. “He’ll be watching for it.”</p>
<p>“And what he then must do?”</p>
<p>“The whole business. He has it down pat from
A to Z.”</p>
<p>Graff settled back in his chair. He appeared satisfied
with these forcible assurances. He fell to rubbing
his hands, his eyes gleaming with malicious triumph,<span class="pagenum">[182]</span>
a gleam and glitter so intense that Patsy Garvan
felt that he was gazing at a madman.</p>
<p>“If he isn’t dippy, a pronounced victim of criminal
mania, I’m no judge of human faces,” he said to himself.
“Human be hanged! He has the look of a
devil, and all the makings of one, if I’m not mistaken.”</p>
<p>“We’ll balk him, thwart him, turn this trick on him,
Shannon, in spite of all he can do,” Graff snapped
viciously after a moment. “Then, if he dares to remain
in Madison—well, God help him! His fate
will be on his own head. I have told him. I have
warned him.”</p>
<p>“He means the chief,” thought Patsy. “This was
the rascal who sent him the letter, and he refers to
the theft of Mrs. Thurlow’s pearls. They’ve been
planning it, and that’s the job Toby Monk is booked
for to-night. If I can but learn the details of their
scheme, it will be soft walking for the chief to foil
their game and collar the entire gang. I’m on the
way, all right.”</p>
<p>Patsy felt reasonably sure of it, indeed, and he was
missing nothing that passed between the two conspirators.
Shannon appeared oblivious to Graff’s display
of feeling, though he smiled a bit grimly and
said:</p>
<p>“You can turn the dick down, all right, if need be,
and none would get wise. All I hope is that he won’t
be able to queer this job. There would be something
coming to us from it, a deal more than usual.”</p>
<p>“It’s as sure as if you already had it in your pocket,
Shannon, if my instructions are carefully followed.”</p>
<p>“They will be,” Shannon nodded. “What does Tim
Hurst think about it? Where does he fit in?”</p>
<p><span class="pagenum">[183]</span></p>
<p>“He’s to work the trick with me.”</p>
<p>“Any one else?”</p>
<p>“Only Dorson.”</p>
<p>“Is it safe to rely upon him?”</p>
<p>“There will be no safety for him if he disappoints
me,” Graff declared, with vicious asperity. “He knows
what it will cost and that he’ll pay the price. You
know what befell the one treacherous cur who dared
to defy me and threatened to expose——”</p>
<p>“Enough of that,” Shannon cut in, with a growl.
“I don’t like to think of it, much less talk about it.
What has become of Hurst, anyway?”</p>
<p>“I have not seen him since last night, after he
searched the rooms of that servile cur.” Graff spoke
with an ugly snarl. “He found papers that would
have exposed us, but they now are ashes only. Luckily,
too, he was in time to down one of the Nick Carter
gang, who otherwise would have found the same
and had us by the ears.”</p>
<p>“We’ll get you all right, sooner or later,” thought
Patsy. “Tim Hurst, eh? The masked man whom
Chick encountered. Give us a little more time and
we’ll uncover all of these hidden faces.”</p>
<p>“Downed him, did he?” queried Shannon. “He
must be a lightweight dick that Tim could down, for
all he’s quick and clever.”</p>
<p>Professor Graff laughed for a moment as if much
tickled, but his mirth had qualities that sent a chill
down Patsy’s spine.</p>
<p>“I had made it easy for him,” Graff replied, still
chuckling with evil pride. “He wore an unsuspected
weapon, an electrical device of mine that would overcome<span class="pagenum">[184]</span>
a horse. Let Tim alone to make good when
in a tight place.”</p>
<p>“But it’s near seven,” Shannon growled, glancing
at the clock. “If he’s to work with you to-night——”</p>
<p>“He’ll come,” Graff cut in quickly. “He’ll show up
on time. He’s due here now.”</p>
<p>“Due here! Will he sneak in this way, or enter
from the front street? If he comes while I’m up
here——”</p>
<p>Patsy caught his breath, scenting speedy trouble.</p>
<p>A key had been thrust into the lock, and almost
instantly the gate was opened and hurriedly closed.
A slender, black-clad figure had entered the alley, a
thin-featured, keen-eyed man of about thirty, who
quickly jerked the key from the lock.</p>
<p>Patsy had as quickly decided what he would do.
He knew he could not leap down from his unsteady
perch undetected and retreat farther into the alley.
He took, therefore, his only chance to escape observation,
knowing that he could not hold up the intruder
without alarming his confederates. Firmly
grasping the stone sill of the window, he drew up
his legs and raised his feet from the top of the door,
hoping the man would pass under him and enter without
seeing him.</p>
<p>The ruse came near proving successful. Tim Hurst
strode quickly to the storm door and flung it open, then
fished out a key to the inner one. He had heard
nothing alarming nor seen the crimped figure hanging
close to the dark wall directly above him.</p>
<p>Just then, however, a bit of cement broke from the
stone under Patsy’s rigid grasp, and it fell straight
down upon Hurst’s head. He drew back as if electrified,<span class="pagenum">[185]</span>
looking up, and as quick as a flash he guessed
the truth. On the instant, too, while he uttered a
short, sharp whistle, he leaped up and seized Patsy’s
legs, snarling fiercely:</p>
<p>“Come down here! Let go, blast you, or——”</p>
<p>Hurst was not given time to say more.</p>
<p>Patsy heard Graff and Shannon spring up and rush
down a back stairway in response to the whistle, and
he realized that only quick work could save him. He
let go of the sill and dropped straight down upon
Hurst’s head and shoulders, worming quickly around
as he pitched over him, and trying to grapple him
around his arms and waist.</p>
<p>The lithe and wiry rascal was alert, however, and
as quick of motion as a cat. He also twisted around
when Patsy fell, spreading his feet to steady himself,
and then, with a lightninglike lurch toward the building,
he brought Patsy’s head against the stone wall, a
blow that nearly cracked his skull and dazed him so
that he hardly knew what immediately followed.</p>
<p>In a vague way, however, he realized that he was
being roughly handled, that Graff and Shannon had
rushed out into the alley, and that the three men were
hurriedly taking him into the building.</p>
<p>He heard both doors closed and locked, then was
conscious of being placed roughly on a cold cement
floor, with two of the ruffians nearly crushing him in
the inky darkness. This was dispelled in a moment
by a glare of electric light, and the cobwebs then
had cleared from his brain sufficiently for him to size
up the surroundings.</p>
<p>He saw at a glance that he was in a chemical laboratory,
a large, square room with shelved walls, laden<span class="pagenum">[186]</span>
with bottles, jars, carboys, and the like. A zinc-covered
table was littered with the customary articles
required by a chemist. There was a closet in one corner.
Near by was an open door, an adjoining entry,
and a narrow stairway leading up to the room in which
the two men had been seated.</p>
<p>Patsy still was gazing around when Graft approached
him, commanding his two confederates to
bind him, which they quickly proceeded to do with
cords brought from the closet, while Tim Hurst hurriedly
stated where he discovered their captive.</p>
<p>“Who are you? Who sent you here to play the
spy?” he fiercely questioned.</p>
<p>Though he keenly realized that he was in wrong,
and that much of his good work might prove futile,
Patsy lost neither his head nor his nerve.</p>
<p>“No one sent me,” he answered curtly. “I came
on my own hook.”</p>
<p>“You lie!” Graff snapped harshly. “You are in
Nick Carter’s employ.”</p>
<p>“By Heaven, I guess that’s right,” Shannon agreed,
with a snarl. “He’s one of the dicks.”</p>
<p>“We’ll dick him! We’ll dick him all right when
the time comes,” Graff fiercely declared. “But not
now, not yet. The Thurlow pearls are of first importance,
and I have only time to prepare for that
job. We’ll settle with him later. Gag him, Shannon,
and lock him in the closet. You must wait here and
watch till we return. Make sure the whelp can’t
escape. I’ll fix him later. I’ll fix him.”</p>
<p>“Gee whiz!” thought Patsy. “If he makes good
as he looks, I can see my finish.”</p>
