Obeying the guidance of a heavy hand that gripped my shoulder, I marched from the room and began to climb the staircase towards the third storey. The whole house was now wrapped in impenetrable darkness. My captors, however, appeared to know the way very well, and I was forced without a pause along a maze of corridors, until we were brought up by a wall. A match was cautiously struck, and we entered a small unfurnished room, the door of which was locked behind us. In the middle of this apartment was a ladder that communicated with the roof. Beudant climbed it with the agility of a monkey and raised a trap in the skylight, through which we all passed in quick succession. As I emerged and stood erect, I saw a sight I shall not easily forget--the magnificent panorama of sleeping Paris. And yet Paris did not seem to sleep. True, the night was dark, but in whatever direction I glanced, I was confronted with myriads of twinkling lamps that gleamed at me like so many intelligent and baneful little eyes. I was given but little time to digest the picture. Before the muzzle of Sir Charles Venner's revolver I crossed a slightly sloping roof of lead, and stepped over a knee-high parapet of stone. Thence we traversed the tops of three other houses and came at length to a slightly lower edifice, which required some care to reach. Beudant slipped over first, and I was bodily lifted up by Fulton and Venner and dropped into his arms. The roof perilously sloped, and the journey filled me with tremors, for a mis-step meant such a destruction as is entailed by a fall of sixty feet upon a line of iron-spiked railings. But death faced me on every side, so I set my lips and strode forward. By great good hap I negotiated the pass in safety, and came to a small, square ledge that was faced with an attic door, covered with a tiny gabled roof. A moment later we were all standing in a long low ceiled chamber, into which we had been admitted by a hideous old beldame. This creature received us with chuckles of sardonic satisfaction, and at once began to haggle with Sir Charles Venner for a large sum of money which she claimed to be her due. He tried to silence her by offering half the amount demanded, but she indignantly declined and threatened to scream. He therefore yielded and gave her his purse. But while she counted the money he turned his back, and taking a phial from his pocket poured its contents on his handkerchief. At a sign Beudant took the handkerchief, and, throwing himself upon the old hag, pressed it tightly to her nostrils. She struggled like a fury, but the negro mastered her, and very soon afterwards she was lying insensible upon the floor. I was watching Sir Charles wrest from her clenched hand his purse, when a terrible blow on my skull deprived me of consciousness.
