The big fellow lying nearest Chang-Wo’s door was clearly the toughest customer of the three, and Bob had decided to tackle him first. He was lying on his back, and his mouth was wide open. Bob crept to his head, Ah-Sam stood at his feet. With a sudden pounce Bob slipped the pad of cloth between his jaws; at the same moment Ah-Sam seized his feet and began to tie them together, and Bob endeavoured to pinion his arms. The Manchu’s position rendered this difficult; he wriggled over, and his arm striking against the floor, roused one of his companions, who half rose upon his elbow. Seeing that Ah-Sam had firmly bound the feet, Bob left him to complete the trussing of the first man and rushed over to deal with the second. The half-dazed fellow had just sat up and begun to look about him when Bob dropped upon him, dealing him a blow that rendered him for the moment harmless. But before Bob could recover his balance, he was himself pulled to the ground by the third man, who had awakened in full possession of his senses. Giving a shout, he got his left hand upon his assailant’s throat; Bob was upon the floor, helpless to resist the horrid clutch. He writhed, he was choking; he felt already that all was over, when the pressure suddenly relaxed; the Manchu fell, a huddled heap, to the ground. Ah-Sam had disobeyed orders. He saw what was happening to his master, and, finding the first man still wriggling, had given him his quietus with the knife, and then darted across the room, to deal in the same way with Bob’s opponent. Bob sprang to his feet. Chang-Wo must by this time have been awakened by the commotion, and might escape by the farther door. There was no time to lose. Pulling the dead Manchu from before the door, Bob flung himself against it. The catch on the inside gave way; he burst into the room; there was a blinding flash, and a bullet crashed through the woodwork within a few inches of his head. In the middle of the room stood the Manchu chief, with a pistol in his hand. Bob made a dash for him, but keeping his eyes on Chang-Wo he failed to notice a pile of quilts on the floor. He tripped. The figure of Ah-Sam coming in support was seen by Chang-Wo, who waited no longer, but rushed to the door leading into the corridor, and slamming it behind him, disappeared.
