'The fatal night arrived. The Baron slept in the arms of his perfidious Mistress, when the Castle-Bell struck 'One.' Immediately Beatrice drew a dagger from underneath the pillow, and plunged it in her Paramour's heart. The Baron uttered a single dreadful groan, and expired. The Murderess quitted her bed hastily, took a Lamp in one hand, in the other the bloody dagger, and bent her course towards the cavern. The Porter dared not to refuse opening the Gates to one more dreaded in the Castle than its Master. Beatrice reached Lindenberg Hole unopposed, where according to promise She found Otto waiting for her. He received and listened to her narrative with transport: But ere She had time to ask why He came unaccompanied, He convinced her that He wished for no witnesses to their interview. Anxious to conceal his share in the murder, and to free himself from a Woman, whose violent and atrocious character made him tremble with reason for his own safety, He had resolved on the destruction of his wretched Agent. Rushing upon her suddenly, He wrested the dagger from her hand: He plunged it still reeking with his Brother's blood in her bosom, and put an end to her existence by repeated blows.
'Otto now succeeded to the Barony of Lindenberg. The murder was attributed solely to the fugitive Nun, and no one suspected him to have persuaded her to the action. But though his crime was unpunished by Man, God's justice permitted him not to enjoy in peace his blood-stained honours. Her bones lying still unburied in the Cave, the restless soul of Beatrice continued to inhabit the Castle. Drest in her religious habit in memory of her vows broken to heaven, furnished with the dagger which had drank the blood of her Paramour, and holding the Lamp which had guided her flying steps, every night did She stand before the Bed of Otto. The most dreadful confusion reigned through the Castle; The vaulted chambers resounded with shrieks and groans; And the Spectre, as She ranged along the antique Galleries, uttered an incoherent mixture of prayers and blasphemies. Otto was unable to withstand the shock which He felt at this fearful Vision: Its horror increased with every succeeding appearance: His alarm at length became so insupportable that his heart burst, and one morning He was found in his bed totally deprived of warmth and animation. His death did not put an end to the nocturnal riots. The bones of Beatrice continued to lie unburied, and her Ghost continued to haunt the Castle.
'The domains of Lindenberg now fell to a distant Relation. But terrified by the accounts given him of the Bleeding Nun (So was the Spectre called by the multitude), the new Baron called to his assistance a celebrated Exorciser. This holy Man succeeded in obliging her to temporary repose; But though She discovered to him her history, He was not permitted to reveal it to others, or cause her skeleton to be removed to hallowed ground. That Office was reserved for you, and till your coming, her Ghost was doomed to wander about the Castle and lament the crime which She had there committed. However, the Exorciser obliged her to silence during his lifetime. So long as He existed, the haunted chamber was shut up, and the Spectre was invisible. At his death which happened in five years after, She again appeared, but only once on every fifth year, on the same day and at the same hour when She plunged her Knife in the heart of her sleeping Lover: She then visited the Cavern which held her mouldering skeleton, returned to the Castle as soon as the Clock struck 'Two,' and was seen no more till the next five years had elapsed.
