It may have been that the new-comer had seen the gleam of the light, or it may have been that he had heard from his comrades of the old man whom they had murdered, and that his curiosity had led him to the spot. He stopped his horse outside the cave, and Simon, lurking in the shadows within, had a fair view of him in the moonlight. He slipped from his saddle, fastened the bridle to a root, and then stood peering through the opening of the cell. He was a very short, thick man, with a dark face, which was gashed with three cuts upon either side. His small eyes were sunk deep in his head, showing like black holes in the heavy, flat, hairless face. His legs were short and very bandy, so that he waddled uncouthly as he walked. Simon crouched in the darkest angle, and he gripped in his hand that same knotted cudgel which the dead theologian had once raised against him. As that hideous stooping head advanced into the darkness of the cell, he brought the staff down upon it with all the strength of his right arm, and then, as the stricken savage fell forward upon his face, he struck madly again and again, until the shapeless figure lay limp and still. One roof covered the first slain of Europe and of Asia. Simon's veins were throbbing and quivering with the unwonted joy of action. All the energy stored up in those years of repose came in a flood at this moment of need. Standing in the darkness of the cell, he saw, as in a map of fire, the outlines of the great Barbaric host, the line of the river, the position of the settlements, the means by which they might be warned. Silently he waited in the shadow until the moon had sunk. Then he flung himself upon the dead man's horse, guided it down the gorge, and set forth at a gallop across the plain. There were fires on every side of him, but he kept clear of the rings of light. Round each he could see, as he passed, the circle of sleeping warriors, with the long lines of picketed horses. Mile after mile and league after league stretched that huge encampment. And then, at last, he had reached the open plain which led to the river, and the fires of the invaders were but a dull smoulder against the black eastern sky. Ever faster and faster he sped across the steppe, like a single fluttered leaf which whirls before the storm. Even as the dawn whitened the sky behind him, it gleamed also upon the broad river in front, and he flogged his weary horse through the shallows, until he plunged into its full yellow tide. * * * * *
