The sight put all doubts out of his head. An attack on Forza was imminent, and this was the side from which least danger would be expected. If the enemy got there before him they would find an easy entrance. The thought made him quicken his pace. These scattered tribesmen must meet before they attacked, and there might still be time for him to get in front. His ears were sharp as a deer's to the slightest sound. A great joy in the game possessed him. When he crouched in the shelter of a granite boulder or sprawled among the scrub while the light footsteps of a tribesman passed on the road he felt that one point was scored to him in a game in which he had no advantages. He blessed his senses trained by years of sport to a keenness beyond a townsman's; his eye, which could see distances clear even in the misty moonlight; his ear, which could judge the proximity of sounds with a nice exactness. Twice he was on the brink of discovery. A twig snapped as he lay in cover, and he heard footsteps pause, and he knew that a pair of very keen eyes were scanning the brushwood. He blessed his lucky choice in clothes which had made him bring a suit so near the hue of his hiding-place. Then he felt that the eyes were averted, the footsteps died away, and he was safe. Again, as he turned a corner swiftly, he almost came on the back of a man who was stepping along leisurely before him. For a second he stopped, and then he was back round the corner, and had swung himself up to a patch of shadow on the crag-side. He looked down and saw his enemy clearly in the moonlight; a long, ferret-faced fellow, with a rifle hung on his back and an ugly crooked knife in his hand. The man looked round, sniffing the air like a stag, and then, satisfied that there was nothing to fear, turned and went on. Lewis, who had been sitting on a sharp jag of rock, swung an aching body to the ground and advanced circumspectly. In an hour or two he came to the top of the slope and the beginning of the second tableland. A grey dimness was taking the place of the dark, and it had suddenly grown bitterly cold. Dawn in such high latitudes is not a thing of violent changes, but of slow and subtle gradations of light, of sudden, coy flushes of colour, of thin winds and bright fleeting hazes. He lay for a minute in the scrub of cloud-berries, the collar of his coat buttoned round his throat, and the morning wind, fresh from leagues of snow, blowing chill on his face. Behind was the slope alive with men who at any moment might emerge on the plateau. He waited for the sight of a figure, but none came; clearly the muster was not yet complete. A thought grew in his brain, and a sudden clearness in the air translated it into action; for in the hazy distance across the tableland he saw the walls of Forza fort.
