r you."

"Why don't you shrink? Why don't you plead for mercy?"

"What's the use?"

She answered him with a laugh that made the room ring.

"Besides," added Nick, "it's not my style to show the white feather."

"We'll see! _Caramba!_ we will see!"

She came nearer to him, crouching before him, so near that her breath
fell hot upon his cheeks. Then, with a quick movement, she pressed the
point of the blade through his clothing, till it pricked the flesh above
his heart.

With his arms bound, with his ankles secured to the legs of the chair,
Nick appeared utterly at her mercy--of which she had none.

Despite himself, Nick shrank slightly from the wound, and for the first
time shuddered at the peril by which he was menaced, and from which
there seemed to be no avenue of escape.

Cervera laughed again, a laugh freighted with the terrible ring of
madness.

"Did it hurt you?" she screamed, with her glittering eyes raised to
search his. "Perdition! I hope so! You have tortured me with a thousand
fears. I'd like to repay you with a thousand pangs!"

Nick's eyes took on an ugly gleam.

"Why don't you do so, then?" he growled.

"I would, if I had the time," cried Cervera, through her teeth.

"You have all there is."

"Ten thousand times I'd thrust it into you--thus! thus!"

Nick set his jaws and met the blade without flinching.

Twice the vicious demon thrust it through his clothing, and now two
crimson stains of blood on his shirt front followed the withdrawal of
the weapon.

"See! see!" screamed Cervera, triumphantly, with her terrible face
upturned to his gaze. "You're beginning to bleed! Did you know that the
sight of blood affects me as it does a leopard? I thirst for more--if
that of one I hate! When next I strike you, I shall strike deeper!"

That she fully intended to murder him, Nick now, had not a doubt. The
homicidal madness was in her eyes, in her every feature, her every
motion, and it rang in every word that fell from her bloodless lips.

Yet the inflexible nerve of the detective did not for a moment desert
him.

"Send the blade home at once, if you like," he said, with a scornful
frown.

"Not yet--not yet!" she cried, shrilly. "There'll be time for that."

"Time and to spare," sneered Nick.

"I first wish to torture you, as you've tortured me!"

"Go ahead, then."

"Once more! Are you ready?"

"Let it come."

Again she drew back the glittering blade, only to mock him with several
