The mind of Ferdinand was highly superior to the general influence of superstition; but, in the present instance, such strong correlative circumstances appeared, as compelled even incredulity to yield. He had himself heard strange and awful sounds in the forsaken southern buildings; he received from his father a dreadful secret relative to them--a secret in which his honor, nay even his life, was bound up. His father had also confessed, that he had himself there seen appearances which he could never after remember without horror, and which had occasioned him to quit that part of the castle. All these recollections presented to Ferdinand a chain of evidence too powerful to be resisted; and he could not doubt that the spirit of the dead had for once been permitted to revisit the earth, and to call down vengeance on the descendants of the murderer. This conviction occasioned him a degree of horror, such as no apprehension of mortal powers could have excited; and he determined, if possible, to prevail on Peter to pass the hours of midnight with him in his dungeon. The strictness of Peter's fidelity yielded to the persuasions of Ferdinand, though no bribe could tempt him to incur the resentment of the marquis, by permitting an escape. Ferdinand passed the day in lingering anxious expectation, and the return of night brought Peter to the dungeon. His kindness exposed him to a danger which he had not foreseen; for when seated in the dungeon alone with his prisoner, how easily might that prisoner have conquered him and left him to pay his life to the fury of the marquis. He was preserved by the humanity of Ferdinand, who instantly perceived his advantage, but disdained to involve an innocent man in destruction, and spurned the suggestion from his mind.
