<h3>CRAFTY CERVERA.</h3>
<p>"Good-evening, Mr. Venner. Oh, it's not you!"</p>
<p>"Oh, yes, 'tis!" said Nick, dryly. "It's I all right, and I'm it. You
appear surprised at seeing me, Señora Cervera."</p>
<p>Cervera had begun, then stopped, then uttered the startled exclamation;
and all with the utmost coolness, with the air of one stirred only by
genuine surprise, and as if without the slightest fear or dismay upon
beholding Nick Carter in the vestibule.</p>
<p>So perfectly natural was her artful assumption, that it rather deceived
Nick for a short time.</p>
<p>In response to his dry remarks, the artful jade now nodded and began to
laugh.</p>
<p>"Surprised? Well, rather!" she exclaimed, in animated tones. "I was
expecting our mutual friend, dear Mr. Venner, and supposed it was he who
rang. But I'm just as pleased to see you."</p>
<p>"Yes?"</p>
<p>"Surely! Come in, Detective Carter. You are very, very welcome. I shall
be so glad to renew our brief acquaintance. In fact, Detective Carter, I
am quite charmed to see you."</p>
<p>"You'll not feel so chipper and charmed when you learn my business,"
said Nick to himself, as he entered and followed her to the library.</p>
<p>"Take a chair, Detective Carter, and try to feel perfectly at home,"
laughed Cervera, with bantering vivacity. "You have been here before,
you know."</p>
<p>"Yes, indeed, I know," said Nick, dryly. "The night I had a taste of a
choke pear, at the hands of your faithful guardians."</p>
<p>"Ah! but you shall be better treated this time," smiled Cervera,
dropping into a chair opposite the detective, and fixing her sensuous,
dark eyes on Nick's calm, unreadable face.</p>
<p>"I hope so, señora," he replied. "By the way, what has become of those
two stalwart guardians of your treasures? Do you still retain them in
your employ?"</p>
<p>It was second nature to Nick to feel his way in this crafty fashion, yet
he did not really expect any resistance in arresting Cervera, who now
laughed and shook her head, replying:</p>
<p>"No, I have let them go."</p>
<p>"That so?"</p>
<p>"I have no use for them at present."</p>
<p>"Why is that?"</p>
<p>"My engagement at the theater has closed, and I seldom have occasion to
wear my diamonds. I have placed them all in a safe deposit vault."</p>
<p>"Ah! I see."</p>
<p>"So I have no need for my guardians, Detective Carter, with only myself
here. Nobody would want me personally, you know," she added, with a bold
laugh.</p>
<p>Nick's firm lips drew a little closer.</p>
<p>"On the contrary," said he, pointedly, "somebody does, want you
personally."</p>
<p>"Oh! is that so?" cried Cervera, as if amused.</p>
<p>"Very much so, señora."</p>
<p>"And who does me the honor, pray?"</p>
<p>"I want you," said Nick, bluntly.</p>
<p>"You, Detective Carter! Why, sir, what an idea! I wouldn't have believed
it of you."</p>
<p>"Yet it is true, nevertheless."</p>
<p>"Well, well," repeated Cervera, with a pretty shrug, "I am really glad
to hear you say so. For what do you want me, Detective Carter?"</p>
<p>Not once had Nick's searching gaze left her brazen countenance, and
despite her outward display of badinage, his steadfast and penetrating
eyes were making her secretly uneasy.</p>
<p>"I want you," said Nick, pointedly, "for that ugly 'Jack-in-the-box'
trick which you perpetrated this afternoon."</p>
<p>Cervera's eyes emitted a single swift, fiery gleam, and her red lips
drew closer. Yet she cried, still pleasantly:</p>
<p>"What do you mean by that, Detective Carter? Is it a joke?"</p>
<p>"You'll find it no joke."</p>
<p>"If it is, sir, I don't see the point."</p>
<p>"You will have a chance to look for it at the Tombs," replied Nick, with
grim quietude. "Señora Cervera, I want you to go along with me."</p>
<p>"The Tombs! Go with you! What do you mean?"</p>
<p>"I mean that you are now under arrest."</p>
<p>"Arrest! For what?"</p>
<p>"For the murder of a girl named Mary Barton," Nick bluntly rejoined,
ignoring the woman's increasing display of amazement and resentment.</p>
<p>"Mary Barton!" cried Cervera. "I never heard of the girl."</p>
<p>"Nevertheless," said Nick, sternly, "you met her on Fifth Avenue this
afternoon, and gave her a jewel casket containing a venomous snake,
which you had stolen from the den of Pandu Singe, and by which means you
inadvertently killed Mary Barton, instead of another for whom your
infernal design was intended. I am aware of all of your late movements,
señora, you see."</p>
<p>"I see that you are a devil!" cried Cervera, with a sudden passionate
outburst. "How dare you come here with such a story as that?"</p>
<p>For a moment at least, the fact that Nick already had discovered nearly
every detail of her infamous crime—though committed only a few hours
before—almost completely unnerved her, and her changing countenance,
her irrepressible outbreak, and the violent agitation of her lithe,
nervous figure, were tokens of self-betrayal by no means unobserved by
Nick.</p>
<p>"You'll have a chance to refute the story before a judge and jury," Nick
curtly answered. "At present you are in my custody, however, and you
must go with me."</p>
<p>Cervera rose to her feet, trembling visibly, and gripped the back of her
chair as if for support.</p>
<p>"There must be some terrible mistake, Detective Carter," she now cried,
with well-feigned distress and alarm. "Surely you do not mean this,
sir? Surely you do but jest?"</p>
<p>"On the contrary, señora, I mean every word that I have said."</p>
<p>"That I am under arrest?"</p>
<p>"Yes."</p>
<p>"And must go with you?"</p>
<p>"Precisely."</p>
<p>"To the Tombs?"</p>
<p>"To the Tombs, señora."</p>
<p>"Oh! this is dreadful—dreadful!" craftily moaned Cervera, with tears
now filling her eyes.</p>
<p>"I am sorry for you, señora, but I must do my duty," said Nick, rising.</p>
<p>"I know you must—but, oh! what shall I do? To whom can I appeal? Oh! if
Mr. Venner were only here!"</p>
<p>"You can send a messenger for him later, or dispatch one of your
servants from here," suggested Nick.</p>
<p>"I have none here," sobbed Cervera. "They are all out, and I am alone. I
have no one—"</p>
<p>She suddenly stopped, then drew herself up with resentful dignity, and
wiped the tears from her eyes.</p>
<p>"I am a fool to be so weak!" she exclaimed, bitterly. "Detective Carter,
I know nothing of the crime you mention. I never heard of Mary Barton.
This arrest is an outrage, and I will appeal to the highest court in the
land for vindication!"</p>
<p>"That's your privilege," said Nick, shortly. "But at present you must go
with me."</p>
<p>"I cannot go as I am," declared Cervera, passionately stamping her
foot. "I am in evening dress—attired to receive a caller. I shall take
cold if I go out of doors in—"</p>
<p>"Oh, you may change your dress," Nick curtly interrupted, the need of
which was decidedly obvious. "I'll give you time for that."</p>
<p>"How very kind," sneered Cervera, with a bitter flash of her black eyes.
"You shall yet suffer for this affront, Detective Carter."</p>
<p>"All right," said Nick. "But I have no time to speculate upon it now, so
get yourself ready. Wait a bit, my lady! I'll go along with you!"</p>
<p>"With me? You insult me!"</p>
<p>"Oh, no, I don't. I want a look at your chamber before letting you out
of my sight. I've seen rooms with more than one way out, and I don't
intend that you shall elude me."</p>
<p>"You're a suspicious coward, sir!"</p>
<p>"Stow all that, señora, and lead the way," commanded Nick, bluntly.</p>
<p>Pale and resentful, with a sneer on her lips, Cervera led the way
through, the hall, playing her part so artfully that Nick, ignorant of
her late interview with Rufus Venner, was not much inclined to suspect
her of duplicity just then.</p>
<p>Upon reaching the top of the hall stairs, Cervera switched on another
light, and then that which illumined her chamber, into which she
haughtily led the detective.</p>
<p>"A fine affront to suffer," she bitterly exclaimed, throwing herself
into a chair. "Your conduct is despicable! You are no gentleman!"</p>
<p>"I am a detective," retorted Nick, "and I come pretty near knowing my
business."</p>
<p>"Oh! you do," sneered Cervera. "Plainly that is the limit of your
knowledge. You may not be as wise as you think."</p>
<p>Nick made no reply, but looked sharply about the room.</p>
<p>It was a large, square chamber, and elaborately furnished. The two
windows were well above the street, and offered no chance for escape.
There were but two doors, that leading into the hall and the one leading
into a large closet in the opposite wall.</p>
<p>Nick opened the latter, and found the closet hung with Cervera's
extensive wardrobe. He thrust his arm along the garments hanging at
either side, and sounded the three walls, and then the closet floor, all
of which appeared perfectly firm and solid.</p>
<p>Even these precautions seemed quite needless to Nick, however, it being
a rented house, and Cervera presumably uninformed of his coming.</p>
<p>"Now, señora, you may have just ten minutes to make ready," said he, as
he rejoined her. "I shall leave this chamber door open, and will wait
for you in the adjoining hall. Can you whistle?"</p>
<p>"Whistle?"</p>
<p>"Yes, whistle! You know what it is to whistle, don't you?"</p>
<p>The sneer on Cervera's red lips, as she arose from her chair, became
almost a smile.</p>
<p>"Yes, I can whistle after a fashion," she admitted.</p>
<p>"Well, then, you keep whistling all the time you are alone here," Nick
sternly commanded. "I will let you out of my sight to make these
changes, but not out of my hearing."</p>
<p>"Suspicious fool!"</p>
<p>"Fool or not, you keep whistling," said Nick, bluntly. "If you let up
for so long as a second, I'll come over yonder threshold in a way that
you'll not fancy."</p>
<p>"But suppose I want to brush my teeth?" inquired Cervera, with a
vixenish light in her evil eyes. "I cannot whistle and brush my teeth,
Detective Carter."</p>
<p>"You'll have plenty of time to brush your teeth at the Tombs," said
Nick, sharply. "Now look lively, mark you, and—keep whistling."</p>
<p>Cervera at once began to whistle.</p>
<p>Nick removed the key from the chamber door, and sauntered out into the
hall, where he kept his ears constantly alert.</p>
<p>Not for a moment did the whistling cease, nor was there the slightest
change in tone or character.</p>
<p>Nick could not have taken a more effective method to serve his present
purpose.</p>
<p>At the end of eight minutes the whistling ceased, and Cervera coldly
cried:</p>
<p>"Now you may come in, Detective Carter. I am about ready to go with
you."</p>
<p>Nick at once entered the chamber.</p>
<p>Cervera had changed her evening dress for a complete suit of black, and
was standing in the middle of the room.</p>
<p>"I suppose," said she, staring icily at the detective, "that I ought to
thank you for your consideration."</p>
<p>"Don't trouble yourself," said Nick, curtly. "I have no time to waste."</p>
<p>"Yet just one word, Detective Carter, before we go."</p>
<p>"Let it be brief, then."</p>
<p>"You are said to be a very clever man, and no doubt you think you have
me dead to rights in this case," said Cervera, with a mocking curl of
her thin lips.</p>
<p>"Decidedly so."</p>
<p>"Yet you will find, Detective Carter, that a clever woman can always
fool and foil a clever man."</p>
<p>"But you, my lady, are very far from being a clever woman," retorted
Nick, with a gesture of impatience, signifying that he wished to leave
with her at once.</p>
<p>"Nevertheless, I shall beat you at the finish, make no mistake about
that," cried Cervera, scornfully. "Now, sir, I will put on my wrap, and
go with you where you please."</p>
<p>With the last remark, she approached a peg in the open closet, as if to
take down a dark shawl.</p>
<p>Instead, she suddenly turned quickly around and cried, with a taunting
laugh:</p>
<p>"So long, Detective Carter! I really feel quite sorry to bid
you—good-by!"</p>
<p>Nick started like a man electrified.</p>
<p>Cervera merely had pressed the peg on which the shawl hung, whereupon
the whole back of the closet seemed to fall away instantly, disclosing a
lighted passage beyond.</p>
<p>Nick caught a glimpse of it, and of the woman darting toward it, and he
followed her like a shot from a gun.</p>
<p>As Cervera passed through the further opening and gained the lighted
passage, she seized and threw a short lever just beyond the closet wall.</p>
<p>At the same moment Nick's weight fell upon the closet floor behind her.</p>
<p>It was like treading upon air.</p>
<p>The lever, like the peg, did not work in an instant.</p>
<p>Nick felt himself falling, and made a desperate clutch at the door
jamb—only to miss it.</p>
<p>Then the closet floor, with the detective upon it, went speeding down
like an elevator cut loose from a top story.</p>
