<h2 class="nobreak" id="CHAPTER_XI">CHAPTER XI.<br/> <span class="cheaderfont">THE ANGLE OF REFLECTION.</span></h2></div>
<p>Doctor David Devoll, whose will and word were
law in the Osgood Hospital, gazed intently at the
card brought in by his personal attendant. He was
seated at a broad, flat desk in the middle of his private
room, a sanctuary into which few would have dared
to intrude after having once offended in that way.</p>
<p>For of all the rules and regulations of this institution,
there was none more inflexible, none more rigorously
enforced, than that forbidding intrusion upon
the privacy of Doctor David Devoll.</p>
<p>And when, perchance, it was violated, which was
very, very seldom, the unfortunate offender had cause
to long remember that suavity and smoothness in a
man may sometimes serve only to hide, like the sleek
coat of a leopard, very sharp claws and merciless teeth.</p>
<p>Doctor Devoll rubbed the top of his bald head with
his slender hands, gazing at the card and muttering
the name inscribed on it.</p>
<p>“Blaisdell—John Blaisdell—I do not place him.
Written with a pen, eh? Do you know the man, Shannon?”</p>
<p>“Not from a side of leather.”</p>
<p>“Not even by sight?”</p>
<p>“Never laid eyes on him. He’s a new one to my
lamps.”</p>
<p>Shannon’s terse replies seemed to issue with husky
quietude from the uppermost depths of his throat.<span class="pagenum">[90]</span>
They were neither refined nor respectful. They
smacked of closer relations than those of master and
servant, as also appeared in his confidential attitude
and air of assurance. For he was bowed over the
desk, with both hands spread upon it, a broad, compact,
muscular man of fifty, with the bullet head of a
pugilist and the strength of a bull. He was clad in
livery, nevertheless—a bottle-green jacket and trousers,
trimmed with black braid.</p>
<p>“He stated, you say, that he has private business
with me.” Doctor Devoll gazed up from the card
with a sinister gleam in his cold blue eyes.</p>
<p>“That’s what he said.”</p>
<p>“But not to what it relates?”</p>
<p>“Not he!” Shannon grinned. “He ducked my question,
as if it were a right swing. When I have private
business with a man, says he, I don’t confide it to his
servant. That was how he countered.”</p>
<p>Doctor Devoll’s thin lips took on a smile that did
not improve his facial expression, usually very agreeable
and benign. He said deliberately:</p>
<p>“You may show him in, Shannon. Wait. Don’t
let his business be too private, not too private, Shannon,”
he added significantly, pointing to a curtained
door. “Slip around there after admitting him and
wait until he goes. You may be needed.”</p>
<p>“I’ll do better than that. If needed, Dave, I’ll be—here!”</p>
<p>“Very good. Show him in.”</p>
<p>Shannon straightened up, smoothed his bottle-green
jacket with his palms, and stalked with stilty stiffness
through the opposite door, closing it after him.</p>
<p>Doctor Devoll reverted to the card.</p>
<p><span class="pagenum">[91]</span></p>
<p>“Written with a pen,” he repeated, his eyes squinted
and gleaming. “But not on one of our office blanks.
Most men have a printed card or engraved. Written
with a pen. One might rightly infer from that, perhaps,
that his name is not—Blaisdell.”</p>
<p>Obviously, Doctor Devoll was more than ordinarily
discerning.</p>
<p>Shannon had, in the meantime, returned to the man
waiting in the hospital office. He then had all the earmarks
of a well-trained butler, thoroughly conscious
of his dignified functions.</p>
<p>“Pardon the delay, sir,” he said sedately. “Doctor
Devoll was talking by telephone with a patient. He
will see you. This way, sir.”</p>
<p>Nick followed him through the main corridor, then
into a narrow diverging passageway, then down three
steps and through a second narrow entry, at the end
of which was the door of the physician’s private room.
Shannon knocked and then opened it.</p>
<p>“Mr. Blaisdell, sir,” he announced.</p>
<p>The detective entered and Doctor Devoll arose to
meet him, bowing and placing a chair.</p>
<p>“Take a seat, Mr. Blaisdell,” he said blandly. “I’m
sorry to have kept you waiting. I was busy with the
telephone.”</p>
<p>“Don’t mention it,” Nick replied. “I shall not take
much of your valuable time.”</p>
<p>He sat down while speaking, and his trained eyes
quickly took in most of the details of the spacious,
handsomely furnished room. Two windows overlooked
the rear grounds. Each was entirely covered
with an interior, painted wire screen, which precluded
observation from outside, but through which one<span class="pagenum">[92]</span>
within could see plainly. There were roller shades
and shutters, also, that would insure privacy after the
lamps were lighted.</p>
<p>The detective saw at once that he was in a rear
room in the main building. He could see the broad
sweep of the rear lawn, the back street in the near distance,
a gravel path leading out to it through the park,
evidently from a near rear door. He no sooner was
seated, moreover, than he saw something else—which
would have been seen and appreciated by only one detective
in a million.</p>
<p>The broad, flat desk was between him and one of
the windows, the light from which struck the top of
the desk at an angle, causing a slight glare on its
smooth leather surface. Two spots that broke this
glare, however, apart from some books and papers
nearer the chair from which the physician had arisen,
instantly caught the detective’s eye.</p>
<p>There was no mistaking the shape of them, nor
what had caused them. They were the broad outlines
of a man’s hands, outspread while he leaned over the
desk, and the moisture from which still lingered on
the smooth leather.</p>
<p>“By Jove, I’ve hit a pair of liars!” thought Nick instantly,
though his strong, clean-cut face did not
change by so much as a shadow. “That fellow in livery
was leaning over the desk, with both hands spread
on it, directly opposite the chair from which this doctor
arose. The dampness from them has not yet dried
from the leather, nor would it have been imparted to
it unless the hands were there for several moments.
That’s an unusual and remarkably confidential attitude
for a servant. The telephone is in one corner and<span class="pagenum">[93]</span>
ten feet from the desk. I’ll wager, by Jove! that the
doctor was not using it, and that something else occasioned
the delay, possibly a conference concerning me
and my mission. Both lied about the telephone, as
sure as I’m a foot high, but for what reason?”</p>
<p>Obviously, of course, these shrewd deductions were
mere impressions that flashed very swiftly through the
detective’s mind, rather than a process of deliberate
reasoning. Naturally, too, they instantly gave rise to
new and somewhat startling suspicions, which, with
characteristic self-control, Carter was careful to conceal.</p>
<p>Doctor Devoll had pattered around his desk, in the
meantime, and was taking the chair from which he
had arisen.</p>
<p>“I am not busy just now, Mr. Blaisdell,” he said.
“I can give you what time you want. What’s the
trouble? You don’t look like a man afflicted with any
physical ailment.”</p>
<p>Nick laughed lightly and shook his head, sizing up
with augmented interest this bald, thin-featured,
smooth-spoken physician who, so singularly and unexpectedly,
had now incurred his distrust.</p>
<p>“No, nothing of the kind,” he replied. “If all men
were as strong and healthy as I am, Doctor Devoll,
those of your profession would find it hard sledding.”</p>
<p>“That is fortunate for you, at least,” smiled the
physician.</p>
<p>“My business with you relates to another matter,”
the detective added.</p>
<p>“Private business—or so my man informed me.”</p>
<p>“Yes.”</p>
<p><span class="pagenum">[94]</span></p>
<p>“Concerning what?” Doctor Devoll’s narrow eyes
took on a searching squint.</p>
<p>“I want to ask you about the girl who was found
unconscious in the hospital grounds late last night,”
Nick explained. “More precisely, I want your opinion
of her condition and the cause of it, as well as of
the three previous cases very closely resembling it.
It strikes me——”</p>
<p>“One moment, sir,” Doctor Devoll interrupted.
“Why are you specially interested in the case?”</p>
<p>“Is that material?” Nick inquired, smiling.</p>
<p>“Quite so. I am not in the habit of discussing my
cases with strangers. I want to know to whom I express
an opinion, and for what reason and by what
right it is asked.”</p>
<p>“Otherwise, Doctor Devoll, you do not express it?”
queried the detective, noting a subtle ring in the other’s
voice. “Is that what I am to infer?”</p>
<p>“Exactly.” Doctor Devoll nodded. “Reticence
would denote a covert motive on your part in seeking
my opinion. I would not stand for that for a moment.
I must be met halfway or I will not discuss a case
with any visitor.”</p>
<p>“That seems to be a consistent position, I’m sure,”
Carter admitted. “I will tell you, therefore, why I
am interested in this case. It was brought to my notice
by Chief Gleason, of the police department, at
whose request I am investigating it.”</p>
<p>“You are a detective, then.”</p>
<p>“Well, merely to that extent,” Nick allowed evasively.</p>
<p>“I see.” Doctor Devoll stroked his black frock coat<span class="pagenum">[95]</span>
and drew up in his chair. “Let me ask you one more
question, Mr. Blaisdell.”</p>
<p>“Certainly.”</p>
<p>“Why is an investigation thought to be necessary?”</p>
<p>“Don’t you consider it wise?”</p>
<p>“For the police to butt in?” Doctor Devoll said a
bit sharply. “I can’t say that I do.”</p>
<p>“No?”</p>
<p>“Why should they interfere? What was there in
either case that demands police investigation?” Doctor
Devoll curtly questioned. “A girl was overcome,
was addicted to a drug, or a dope of some kind, and
wandered into the hospital grounds. She was found
and brought in here. I revived her and she immediately
insisted upon going home. That’s all there was
to any one of the cases. Why, I repeat, do they require
police investigation?”</p>
<p>“I cannot conceive, Doctor Devoll, that you have
any personal objection to an investigation,” Nick remarked
dryly, smiling again.</p>
<p>A tinge of red leaped up in the physician’s cheeks.
A sharper gleam shot from his squinted eyes. He detected
a covert insinuation in his visitor’s tone. He
felt that he had said too much, perhaps, for he quickly
retorted:</p>
<p>“Not the slightest objection, Mr. Blaisdell, not the
slightest objection. I merely fail to see why an investigation
is necessary. There are hundreds of dope
fiends in every large city, but in none of them have the
police a very great interest. Why their activity, then,
in these cases? What do they suspect?”</p>
<p>“Don’t you think that four such cases warrant suspicion?”
the detective blandly inquired.</p>
<p><span class="pagenum">[96]</span></p>
<p>“Not more than the hundreds I have mentioned.”</p>
<p>“But all were found in the hospital grounds,” Carter
pointed out suggestively.</p>
<p>“What of that?” Doctor Devoll demanded. “A
coincidence. Nothing else. One may have been influenced
by having read of the others. There is no
accounting for the doings of a drug fiend.”</p>
<p>“There is some truth in that,” Nick admitted.</p>
<p>“Let it go at that, then,” said Doctor Devoll, with
a wave of his slender hands. “I wanted only to learn
your opinion, your grounds for suspicion. You now
are welcome to mine. I will answer any question you
care to ask.”</p>
<p>“Thank you,” said the detective, who now was taking
a somewhat different course than he would have
shaped if he had detected nothing denoting duplicity
in the physician. “You think these girls were drug
fiends, do you?”</p>
<p>“I don’t know positively,” Doctor Devoll said
quickly. “I am not sure that the coma in which I
found them was the cause of a drug. There is a possibility,
of course, that the cause was a temporary
atrophy of the cerebral nerves.”</p>
<p>“But you intimated to Sergeant Brady that they
were drugged,” Nick reminded him.</p>
<p>“That was and still is what I suspect, but I am
not sure of it,” Doctor Devoll retorted. “I had not
time to look deeply into either case. My duty was to
restore my patient, which I succeeded in doing, and
each of them then insisted upon departing and going
home.”</p>
<p>“Why didn’t you detain them?”</p>
<p><span class="pagenum">[97]</span></p>
<p>“I had no right to do so. One may leave here as
soon as able. This is not a police station.”</p>
<p>“But why didn’t you question them about their
habits, Doctor Devoll, and insist upon knowing their
names?” the detective asked more pointedly.</p>
<p>“I did so in the last case.”</p>
<p>“Why not in the others? It strikes me——”</p>
<p>“Stop a moment,” Doctor Devoll interrupted, lurching
forward in his chair. “I run this institution, Mr.
Blaisdell, and I’m not going to be bothered in this way
nor have my conduct picked to pieces by the police.
When another case turns up, I would advise your
having her taken to headquarters. You then can call
another physician. Get him to restore her. He may
know more than I.</p>
<p>“You can hold the girl, charge her with something,
frame her up in any way you like, which is quite in a
line with police methods, and, perhaps, you can force
her to impart all the information you want. I know
no other way by which you can learn the truth.”</p>
<p>Doctor Devoll arose with the last, signifying that he
would not prolong the interview. Carter had let him
run on without interrupting, noting his impatience
and a more threatening shrillness in his voice. He
decided not to question him further. He arose and
took his hat, saying with ominous quietude:</p>
<p>“There is another way, Doctor Devoll, and I shall
find it. I’m going to dig out the whole truth, not only
in these cases, but also in the sudden mysterious death
of Gaston Todd. There is, I now feel sure, quite a
close relation between all of these cases and the many
mysterious robberies that have recently been committed
in Madison. I want the whole truth, Doctor<span class="pagenum">[98]</span>
Devoll, and I’m out to get it. Take it from me—I’ll
find the way.”</p>
<p>“I wish you much success.” Doctor Devoll’s thin
lips took on a rather sardonic smile. “I wish you
much and speedy success, Mr. Blaisdell. This way, sir,
if you are going. Call again. I shall be interested
to know how you succeed and to learn the true inwardness
of these mysteries. Ah, here is my man. Show
Mr. Blaisdell the way, Shannon, if you please. Call
again, sir; call again.”</p>
<p>“Thank you. I think it highly probable,” said Carter,
with singular dryness.</p>
<p>Doctor Devoll bowed, still smiling, and closed the
door, to which he had accompanied the detective.</p>
<p>Nick Carter followed Shannon out by the way he
had entered, departing without so much as a word to
the burly attendant. There was a suspicious gleam in
the latter’s eyes, however, while he watched the departing
detective through one of the office windows.
Turning abruptly, as if hit with a sudden idea, he
closed the office door and then called up the police
headquarters by telephone.</p>
<p>“Hello!” said he, with a voice very unlike his own.
“One of Carter’s assistants is talking from the Wilton
House. Do you know where I can find him?”</p>
<p>A sergeant answered, one who happened to know
of Carter’s relations with the chief, but upon whom
the above inquiry made no impression and was not
afterward recalled.</p>
<p>“I do not,” he replied. “He has not been here since
morning.”</p>
<p>Shannon hung up the receiver; then arose and hurried
back to rejoin the physician.</p>
<p><span class="pagenum">[99]</span></p>
<p>“I’m wise, Dave,” he announced, with an exultant
snarl. “I’ve nailed him.”</p>
<p>Doctor Devoll swung around from the fireplace,
near which he was standing.</p>
<p>“Wise to what?” he demanded. “Do you mean
that you know him?”</p>
<p>“You bet I know him. Brady, you remember, telephoned
to a man named Blaisdell last night, who is at
the Wilton House. It just struck me that Gleason has
employed outside detectives. There is just one crack
sleuth whom he most likely would want. I have
phoned to headquarters, saying I was his assistant and
asking if he was there. I was told that he was there
this morning. That does settle it. You have just
been talking, Dave, with the famous New York detective,
the worst ever—Nick Carter.”</p>
<p>Doctor Devoll started slightly and for a moment
appeared incredulous. Then his teeth met with a vicious
snap. His face changed as if he had been suddenly
turned to a devil incarnate.</p>
<p>“You are sure of it, Shannon, sure of it?” he questioned,
with a sibilant hiss.</p>
<p>“Dead sure, Dave,” Shannon insisted. “There’s
nothing to it.”</p>
<p>“Nick Carter, eh? The worst ever, eh?” Doctor
Devoll gave way to a mirthless, derisive laugh. “We’ll
see about that. We’ll see about that, Shannon. He
shall find that he has met one worthy of his steel, one
who will balk, thwart, and laugh at him. Or, if need
be, Shannon, who will wipe him from the face of the
earth!”</p>
<p>Shannon shrugged his broad shoulders and smiled
grimly. It was not the first time that he had heard<span class="pagenum">[100]</span>
such sentiments as these, and seen that same gleam
and glitter in the eyes of the man confronting him,
eyes with a glare like that of madness.</p>
<p>“You will not quit, then?” he said inquiringly.</p>
<p>“Quit!” Doctor Devoll sneered scornfully. “Only
curs and cowards quit, Shannon, and throw up the
sponge. Sit down at my desk. Sit down and write
what I dictate. Your hand will never be suspected.”</p>
<p>Shannon obeyed him without a protest. He was
accustomed to yielding to this man, to obeying him
without question. He sat down at the desk, taking the
pen and paper which the physician provided. Half
an hour had passed when Doctor Devoll ended his
dictation and gave the other his instructions.</p>
<p>Shannon arose and went to change his livery for
street attire.</p>
<p>Doctor Devoll, with face still reflecting his vicious
sentiments, gazed intently at his desk for several moments.
Then he started abruptly, having decided what
course he would shape, and hurriedly opened a safe
in one corner, taking from it a small rubber mask,
which he quickly adjusted over his mouth and nostrils.
Then he took from an inner compartment—a small
leather bag.</p>
<p>Out of the latter he drew a crumpled handkerchief,
lady’s size, and hurriedly cast it with the bag into the
fireplace. A blue flame sprang up, hissing audibly,
denoting that the handkerchief was saturated with a
very volatile and inflammable substance of some kind.
The physician watched them burn, smiling sardonically;
then forced the charred remains deep among the
glowing embers.</p>
<p>“Nick Carter, eh?” he muttered, relocking the mask<span class="pagenum">[101]</span>
in his safe. “He suspects me, does he? He’ll corner
me, will he? We shall see—we shall see!”</p>
<p>When Shannon returned, he had a disguise in his
hand, which he was placing temporarily in his pocket.</p>
<p>Doctor Devoll started up from his desk with two
sealed letters, which he had hurriedly written. He
gave them to his attendant, saying sharply, with eyes
gleaming again:</p>
<p>“This to Toby Monk. This to Tim Hurst. Be
wary when leaving the other, Shannon, both wary and
watchful. Nick Carter, eh? We shall see, Shannon,
we shall see!”</p>
