"You shall assist it. I have sworn he shall die before dawn, and the hand to strike the blow shall be yours."

"Mine! never!"

"Your own life will be the penalty of your obstinacy, if you refuse; nor will your refusal save him. By the Mother of Heaven, he dies! and by your hand. You saw how he was struck by your resemblance to the young Englishman this morning in the chiesa. It is wonderful! I know not who or what you are; but to me you are an instrument of vengeance, and as such I shall use you. The blow dealt by you will seem the work of retribution; and I care not if you strike twice, and make my heart your second mark."

Ere I could reply he called to his comrades, and in a few moments we were speeding across the campagna.

We arrived at a high wall:—the old man conducted us to a postern-gate, which he opened. We entered a garden filled with orange-trees, the perfume of which loaded the midnight air. We heard the splash of a fountain at a distance, and the thrilling notes of a nightingale amongst some taller trees. The moon hung like a lamp over the belvidere of the proud villa. We strode along a wide terrace edged by a marble balustrade. The old man pointed to an open summer-house terminating the walk, and gave me a significant look, but he spoke not. A window thrown open admitted us to the house. We were within a hall crowded with statues, and traversed noiselessly its marble floors. Passing through several chambers, we then mounted to a corridor, and entered an apartment which formed the ante-room to another beyond it. Placing his finger upon his lips, and making a sign to his comrades, Cristofano opened a door and disappeared. There was a breathless pause for a few minutes, during which I listened intently, but caught only a faint sound as of the snapping of a lock.

Presently the old man returned.

"He sleeps," he said, in a low deep tone to me; "sleeps as his victim slept—sleeps without a dream of remorse; and he shall awaken, as she awoke, to despair. Come into his chamber!"

We obeyed. The door was made fast within side.

The curtains of the couch were withdrawn, and the moonlight streamed full upon the face of the sleeper. He was hushed in profound repose. No visions seemed to haunt his peaceful slumbers. Could guilt sleep so soundly? I half doubted the old man's story.

Placing us within the shadow of the canopy, Cristofano approached the bed. A stiletto glittered in his hand. "Awake!" he cried, in a voice of thunder.
