“By Jove! that’s true,” said the detective. “Now that I come to think of it, Dr. Barnicot’s bust was broken not far from his red lamp. Well, Mr. Holmes, what are we to do with that fact?”

“To remember it⁠—to docket it. We may come on something later which will bear upon it. What steps do you propose to take now, Lestrade?”

“The most practical way of getting at it, in my opinion, is to identify the dead man. There should be no difficulty about that. When we have found who he is and who his associates are, we should have a good start in learning what he was doing in Pitt Street last night, and who it was who met him and killed him on the doorstep of Mr. Horace Harker. Don’t you think so?”

“No doubt; and yet it is not quite the way in which I should approach the case.”
