"By Jove, listen to this," he exclaimed. "Here's a strange thing for you. Some houses seem famed for tragedy, like some men are."

"Something in your line?" Bruce asked.

"Well, I should say so. Listen:"

"'The Tragedy of the Corner House.'"

"'The Corner House keeps up its reputation. A mysterious murder in Raven Street where an undiscovered crime happened years ago.

"'At a little past twelve today a policeman on duty in Raven Street saw that the door of an unoccupied furnished house was open, and proceeded to investigate the premises. In a room upstairs he found the body of a man with his throat cut and a horrible wound at the back of his head. Robbery appears to be the motive. The matter is all the more mysterious as the place called the Corner House has been supposed to be shut up for years. It was here that the famous "Corner House" poisoning mystery took place.

"'Later.--The murdered man is described as being of misshapen appearance, a nose very much hooked on one side, and long hands, covered with orange-coloured warts----'"

"What?" Bruce cried. "Read that over again."

"Do you mean to say you know anything about it?" Lawrence asked.

"He was my patient," Bruce said hoarsely. "I was with him at daybreak."
