You may be surprized that during this time I made no enquiries after your Sister. Theodore, who with difficulty had discovered my abode, had quieted my apprehensions for her safety: At the same time He convinced me that all attempts to release her from captivity must be fruitless till I should be in a condition to return to Spain. The particulars of her adventure which I shall now relate to you, were partly communicated to me by Theodore, and partly by Agnes herself.
On the fatal night when her elopement was to have taken place, accident had not permitted her to quit her chamber at the appointed time. At length She ventured into the haunted room, descended the staircase leading into the Hall, found the Gates open as She expected, and left the Castle unobserved. What was her surprize at not finding me ready to receive her! She examined the Cavern, ranged through every Alley of the neighbouring wood, and passed two full hours in this fruitless enquiry. She could discover no traces either of me or of the Carriage. Alarmed and disappointed, her only resource was to return to the Castle before the Baroness missed her: But here She found herself in a fresh embarrassment. The Bell had already tolled 'Two:' The Ghostly hour was past, and the careful Porter had locked the folding gates. After much irresolution She ventured to knock softly. Luckily for her, Conrad was still awake: He heard the noise and rose, murmuring at being called up a second time. No sooner had He opened one of the Doors, and beheld the supposed Apparition waiting there for admittance, than He uttered a loud cry, and sank upon his knees. Agnes profited by his terror. She glided by him, flew to her own apartment, and having thrown off her Spectre's trappings, retired to bed endeavouring in vain to account for my disappearing.
In the mean while Theodore having seen my Carriage drive off with the false Agnes, returned joyfully to the Village. The next morning He released Cunegonda from her confinement, and accompanied her to the Castle. There He found the Baron, his Lady, and Don Gaston, disputing together upon the Porter's relation. All of them agreed in believing the existence of Spectres: But the Latter contended, that for a Ghost to knock for admittance was a proceeding till then unwitnessed, and totally incompatible with the immaterial nature of a Spirit. They were still discussing this subject when the Page appeared with Cunegonda and cleared up the mystery. On hearing his deposition, it was agreed unanimously that the Agnes whom Theodore had seen step into my Carriage must have been the Bleeding Nun, and that the Ghost who had terrified Conrad was no other than Don Gaston's Daughter.
