The lower part of the castle was hollowed into several intricate cloisters, and it was not easy for one under so much anxiety to find the door that opened into the cavern.  When in that long labyrinth of darkness a gust of wind extinguished her lamp, words cannot paint the horror of her situation.  It gave her a momentary relief to perceive a ray of moonshine gleam from the roof of the vault, which seemed to be fallen in; but as she advanced, she discerned a human form standing close against the wall.

She shrieked, believing it to be the ghost of Conrad.  But the figure asked her, in a submissive voice, not to be alarmed.  “Sir, whoever you are,” she replied, “assist me to escape from this fatal castle.”

“Alas!” said the stranger, “what can I do to assist you?”

“Oh!” said Isabella, “help me but to find the trap-door that is hereabout; it is the greatest service you can do me.”

With a little searching they found the trap-door; the stranger lifted it, and Isabella descended to some stone steps below.  The stranger was about to follow, when the voice of Manfred was heard in the distance.  “Make haste or we are ruined!” cried Isabella.  But the door slipped out of his hands and fell with a crash.  Instantly Manfred, who had heard the noise, hastened up, accompanied by servants with torches.

“It must be Isabella escaping by the subterraneous passage,” he cried.

What was his astonishment when the light discovered to him the young peasant whom he had thought confined under the helmet.

“Traitor, how camest thou here?” said Manfred.

“I am no traitor,” replied the young man, “and that is how I came here.”

He pointed upwards, and Manfred perceived that one of the cheeks of the casque had broken through the pavement of the court, as his servants had let it fall over the peasant, and had made a gap through which the young man had escaped.

“And what noise was that which I heard?” asked Manfred.

“Providence led me to the trap-door,” answered the peasant, “but I let it fall.”

Manfred removed him to confinement in the castle, and continued his vain search for Isabella.

II.—­Father Jerome

On the following morning Manfred went to Hippolita’s apartment, to inquire if she knew aught of Isabella.  While he was questioning her, word was brought that Father Jerome demanded to speak with him.  Manfred ordered him to be admitted.

“Is your business with me or the Princess?” asked Manfred.

“With both,” replied the holy man.  “The lady Isabella—­”

“What of her?” interrupted Manfred eagerly.

—­“Is at St. Nicholas altar,” replied Jerome.

“That is no business of Hippolita,” said Manfred with confusion; “let us retire to my chamber.”

“No, my lord,” said Jerome firmly; “my commission is to both, and in the presence of both I shall deliver it.  But first I must interrogate the Princess, whether she is acquainted with the cause of the lady Isabella’s flight.”
