It was a tremendously virile and yet sinister face which was turned towards us. With the brow of a philosopher above and the jaw of a sensualist below, the man must have started with great capacities for good or for evil. But one could not look upon his cruel blue eyes, with their drooping, cynical lids, or upon the fierce, aggressive nose and the threatening, deep-lined brow, without reading Nature’s plainest danger-signals. He took no heed of any of us, but his eyes were fixed upon Holmes’s face with an expression in which hatred and amazement were equally blended. “You fiend!” he kept on muttering. “You clever, clever fiend!”

“Ah, Colonel!” said Holmes, arranging his rumpled collar. “ ‘Journeys end in lovers’ meetings,’ as the old play says. I don’t think I have had the pleasure of seeing you since you favoured me with those attentions as I lay on the ledge above the Reichenbach Fall.”

The colonel still stared at my friend like a man in a trance. “You cunning, cunning fiend!” was all that he could say.
