If you are going back to Pitt Street, you might see Mr. Horace Harker. You can tell him that I am sure that a dangerous madman and killer, with Napoleonic delusions, was in his house last night. He will want to use this information in his article."

Lestrade stared at Holmes. "Do you really believe that?"

Holmes smiled. "Do I? Well, perhaps I don't. But I am sure that my opinion will interest Mr. Horace Harker and the people who buy his news stories. Now, Watson, I think that we might have a long and rather busy day with a lot of work to do. For this, I would like to keep the photograph which we found in the dead man's pocket. Lestrade, I hope you can meet us at Baker Street at six o'clock this evening. If what I think is correct, I may have to ask for you to come with me and give me your help on a short journey tonight. Until then good-bye and good luck!"

Sherlock Holmes and I walked together to the High Street. There we stopped at the shop of Harding Brothers, where the bust had been bought. A young assistant told us that Mr. Harding would be away until that afternoon. The shop assistant was a newcomer, who could tell us nothing else. Holmes's face showed his disappointment and annoyance.
