'And even were the villain to come back alone,' thought Frank, 'were I to spring upon him, he might give some signal which would bring to his aid his band of desperadoes from the Vaults below. No--I must not needlessly peril my own life; I will depart from the house now, satisfied for the present with the discoveries I have made, and trusting to be enabled at no distant time to come here with a force sufficient to overcome the hideous ruffian and all his band.' Leaving the cellar, he traversed the entry and attempted to open the front door; but to his surprise it was securely locked, nor could all his efforts push back the massive bolts which held it fast. He re-entered the room, and examining the windows, found them furnished with thick iron bars like the windows of a prison, so that to pass through them was impossible; and further investigation resulted in the unpleasant conviction that he was a prisoner in that dreadful house, with no immediate means of escape. He again descended into the cellar, and began seriously to reflect upon the realities of his situation. He was a young man of determination and courage: yet he could not entirely subdue those feelings of uneasiness and alarm which were natural under the circumstances. He was alone, at midnight, in that abode of crime and murder; near him lay the corpse of an unfortunate fellow creature, who had without a doubt fallen by the hand of an assassin; he was momentarily expecting the return of that arch-miscreant, who would show him no mercy; a deep, unbroken silence, and an air of fearful mystery, reigned in that gloomy cellar and throughout that awful house--and before him, dark and yawning as the gate of hell, was that black and infernal pit which led to the subterranean caverns of the Dark Vaults, far below. 'I will sell my life dearly, at all events,' thought our hero, as he drew a bowie knife from his breast, and felt its keen, glittering edge; then impelled by a sudden thought, he advanced to the mouth of the pit, and cut the four ropes, which sustained the wooden platform, so nearly asunder, that they would be almost sure to break with a slight additional weight. He had scarcely accomplished this task, when a strange, unnatural cry resounded throughout the cellar--a cry so indescribably fearful that it chilled his blood with horror. It was almost instantly followed by a low and melancholy wail, so intense, so solemn, so profoundly expressive of human misery, that Frank was convinced that some unfortunate being was near him, plunged in deepest anguish and distress. In a few moments the sound entirely ceased, and silence resumed its reign; then Frank, actuated by the noble feelings of his generous nature, said, in a loud voice-- 'If there is any unhappy creature who now hears me, and who needs my charitable aid, let him or her speak, that I may know where to direct my search.'
