Brandilancia could see the distant flare of torches, and he knew that his candle was as plainly visible to his pursuers. He dared not extinguish it, but quickened his pace to a run, slipping, almost falling into the water as he dashed recklessly forward. Suddenly, but not an instant too soon, he halted before a void. The pathway had disappeared; another step and he would have plunged into a reservoir of unknown depth which yawned without a barrier before him. As he lifted his candle and peered across the wide expanse he saw that the tunnel was closed directly opposite him by a wall of solid masonry, and in his dismay almost a minute elapsed before he discovered to the left an open archway which indicated that the tunnel here turned at an angle. But how should he cross to this doorway? The coping which separated the cistern from the canal in the centre of the tunnel was too narrow and the water poured over it noisily. He was about to attempt swimming when he noticed that he was standing upon a plank, evidently placed here to be used as a bridge. He retreated a few steps and pushed it cautiously forward. It reached across the cistern and rested upon the sill of the arched doorway. In the brief interval thus consumed the footsteps had gained upon him and in the light of the approaching torches he plainly recognised Radicofani, who shouted to him to surrender. Thus beset he ventured the crossing, but the plank was rotten and broke under his weight, falling with him into the reservoir. He struck out in the direction in which he imagined the archway to be, by good fortune found it by feeling along the wall, and clambered upon the ledge which ran along the side of the conduit as in the first tunnel. He had suffered no other harm than the thorough wetting and the loss of his candles, and the torches of his pursuers, who had now reached the opposite side of the cistern, showed that the tunnel was slightly wider than its opening, and that by hugging the wall he was not visible to Radicofani. The latter had heard the splash and regarded the water dubiously. "Have you gone to the bottom?" he shouted, but Brandilancia was wisely silent. "If not," cried the Captain, "and you are hiding yonder within hearing, let me tell you that you will die like a rat in a sewer unless you give yourself up at the entrance to that tunnel, where you will find me waiting for you." Drenched to the skin Brandilancia's teeth chattered with the physical cold, and fear numbed his heart. "What if Radicofani spoke the truth?"
