were busy, while every now and then he would look up and measure with a glance the distance which still separated us. Nearer we came and nearer. Jones yelled to them to stop. We were not more than four boat’s lengths behind them, both boats flying at a tremendous pace. It was a clear reach of the river, with Barking Level upon one side and the melancholy Plumstead Marshes upon the other. At our hail the man in the stern sprang up from the deck and shook his two clinched fists at us, cursing the while in a high, cracked voice. He was a good-sized, powerful man, and as he stood poising himself with legs astride I could see that from the thigh downwards there was but a wooden stump upon the right side. At the sound of his strident, angry cries there was movement in the huddled bundle upon the deck. It straightened itself into a little black man—the smallest I have ever seen—with a great, misshapen head and a shock of tangled, dishevelled hair. Holmes had already drawn his revolver, and I whipped out mine at the sight of this savage, distorted creature. He was wrapped in some sort of dark ulster or blanket, which left only his face exposed; but that face was enough to give a man a sleepless night. Never have I seen features so deeply marked with all bestiality and cruelty. His small eyes glowed and burned with a sombre light, and his thick lips were writhed back from his teeth, which grinned and chattered at us with a half animal fury. “Fire if he raises his hand,” said Holmes, quietly. We were within a boat’s-length by this time, and almost within touch of our quarry. I can see the two of them now as they stood, the white man with his legs far apart, shrieking out curses, and the unhallowed dwarf with his hideous face, and his strong yellow teeth gnashing at us in the light of our lantern.
