Then back into the room. He slams the door, picks up the chisel, and drives it with the hammer between the heavy oak and the floor. Off with his jacket, off with his vest; he rolls them up and forces them through the window. Everything must be dared now! Then feet foremost into the window-recess; out, out, grasping the rope; his legs are through, his body follows. Is the gap wide enough? He jerks himself on; it is a tight fit; his shoulders are through; he is dangling in the air, his arms almost forced from their sockets. Down he goes, hand over hand; his feet find the rope; he hears the clamour of blows on the door above. Down, down, faster and faster, the strain upon his muscles increasing with every foot of distance; down into what seems an immeasurable gulf. His feet touch the projecting sill of a window; he finds a momentary relief; then down again into space; there can be no delay, even for a moment. At last, panting for breath, his hands sore and bleeding, Bob feels a pair of arms supporting him; he loosens his grip of the rope, and falls half-insensible to the ground. But only for an instant. He sees as in a mist the outlines of two men, who drag him to his feet. The next moment, as though impelled by some higher will, he is racing down the frozen bank between the two shorter figures, over the creaking ice, towards the middle of the stream. Shouts pursue him, reflections of lights dance before his dazzled eyes, a shot is fired, there is a babel along the walls. Hauled up on the ice lies a small sampan. One of his supporters half pushes, half hurls Bob into it, then both urge it over the sagging ice into the stream. The edge gives way, the sampan slides with a glug into deep water, the two men leap on board with the agility of panthers, and the light craft bounds forward on its way to the sea. *CHAPTER XIII* *Ah-Sam* A Silent Journey—An Old Friend—Circumstances Alter Cases—Enter Ah-Sam—A Manchurian Inn—Held Up—Chinese Receipts
