“Be not alarmed, Lady; I will not injure you.”

Isabella, a little encouraged by the words and tone of voice of the stranger, and recollecting that this must be the person who had opened the door, recovered her spirits enough to reply—

“Sir, whoever you are, take pity on a wretched Princess, standing on the brink of destruction. Assist me to escape from this fatal castle, or in a few moments I may be made miserable for ever.”

“Alas!” said the stranger, “what can I do to assist you? I will die in your defence; but I am unacquainted with the castle, and want—”

“Oh!” said Isabella, hastily interrupting him; “help me but to find a trap-door that must be hereabout, and it is the greatest service you can do me, for I have not a minute to lose.”

Saying these words, she felt about on the pavement, and directed the stranger to search likewise, for a smooth piece of brass enclosed in one of the stones.

“That,” said she, “is the lock, which opens with a spring, of which I know the secret. If we can find that, I may escape—if not, alas! courteous stranger, I fear I shall have involved you in my misfortunes: Manfred will suspect you for the accomplice of my flight, and you will fall a victim to his resentment.”

“I value not my life,” said the stranger, “and it will be some comfort to lose it in trying to deliver you from his tyranny.”

“Generous youth,” said Isabella, “how shall I ever requite—”

As she uttered those words, a ray of moonshine, streaming through a cranny of the ruin above, shone directly on the lock they sought.
