"Do you feel quite sure of it?"

"Absolutely."

"Then I think I'd better see your finish this very night, since I now have you cornered!" cried Cervera, in taunting tones, "It may not be wise to defer it."

Then Nick beheld a second burning newspaper coming his way.

"Let up, you demon!" he shouted, angrily. "You'll set the house afire."

"Wouldn't it be a shame! And what would become of you?"

"Don't try it again, young woman, or worse may be your fate."

"Oh! is that so?" sneered Cervera, maliciously. "We'll see."

Down came another burning paper, and by the light of it Nick now discovered a closed door in one of the walls. It was directly under the closet door in Cervera's chamber, both of which evidently had once been used for entering the elevator.

The fact chiefly observed by Nick, however, was that the sill of the door was wide enough to offer him a safe footing. Though it was fully eight feet above his head, Nick resolved to attempt to reach it by means of the notched iron on the side wall.
