“The porter was a little surprised, but said nothing, but when half an hour had gone by he grew uneasy and going upstairs to the sitting-room discovered what you have just seen.

“The body was not touched, and we were immediately summoned by the police at Bow Street. The police-surgeon happened to be absent, and has not yet called. That accounts for the body being still undisturbed. We had, as a matter of fact, only been here a few minutes when you yourself arrived.”

“Is that all?” asked Westerham.

“That's all that I can tell you up to the present,” said the detective.

“What were the men like?” asked Westerham, though he had by this time little doubt as to the identity of the murderer, just as he knew well enough the identity of the victim.

“The murdered man,” said the detective, “you have seen yourself. The murderer—for there is not the slightest doubt that the taller of the two men stabbed the other—is described as being spare in build and black-bearded.”

“Black-bearded?” said Westerham, wonderingly.

Rookley looked at him sharply.

“You have suspicions?” he said.

“Is there a man without them?” asked Westerham.
