The richest and glossiest of curtains and tapestries draped the walls, looped back here and there to expose some richly-mounted painting or Oriental vase. The carpet was of amber-and-black, so soft and so thick that the foot sank pleasantly into it, as into a bed of moss. Two great tiger-skins thrown athwart it increased the suggestion of Eastern luxury, as did a huge hookah which stood upon a mat in the corner. A lamp in the fashion of a silver dove was hung from an almost invisible golden wire in the centre of the room. As it burned it filled the air with a subtle and aromatic odor.

"Mr. Thaddeus Sholto," said the little man, still jerking and smiling. "That is my name. You are Miss Morstan, of course. And these gentlemen--"

"This is Mr. Sherlock Holmes, and this is Dr. Watson."
