If you are going back to Pitt Street, you might see Mr. Horace Harker. Tell him for me that I have quite made up my mind, and that it is certain that a dangerous homicidal lunatic, with Napoleonic delusions, was in his house last night. It will be useful for his article."

Lestrade stared. "You don't seriously believe that?"

Holmes smiled. "Don't I? Well, perhaps I don't. But I am sure that it will interest Mr. Horace Harker and the subscribers of the Central Press Syndicate. Now, Watson, I think that we shall find that we have a long and rather complex day's work before us. I should be glad, Lestrade, if you could make it convenient to meet us at Baker Street at six o'clock this evening. Until then I should like to keep this photograph, found in the dead man's pocket. It is possible that I may have to ask your company and assistance upon a small expedition which will have to be undertaken tonight, if my chain of reasoning should prove to be correct. Until then good-bye and good luck!"

Sherlock Holmes and I walked together to the High Street, where we stopped at the shop of Harding Brothers, where the bust had been purchased. A young assistant informed us that Mr. Harding would be absent until afternoon, and that he was himself a newcomer, who could give us no information. Holmes's face showed his disappointment and annoyance.
