"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." "What would you do, then?" "Oh, you must not let me influence you in any way! I suggest that you go on your line and I on mine. We can compare notes afterwards, and each will supplement the other." "Very good," said Lestrade. "If you are going back to Pitt Street you might see Mr. Horace Harker. Tell him from 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 to-night, 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 he stopped at the shop of Harding Brothers, whence the bust had been purchased. A young assistant informed us that Mr. Harding would be absent until after noon, and that he was himself a newcomer who could give us no information. Holmes's face showed his disappointment and annoyance. "Well, well, we can't expect to have it all our own way, Watson," he said, at last. "We must come back in the afternoon if Mr. Harding will not be here until then. I am, as you have no doubt surmised, endeavouring to trace these busts to their source, in order to find if there is not something peculiar which may account for their remarkable fate. Let us make for Mr. Morse Hudson, of the Kennington Road, and see if he can throw any light upon the problem." A drive of an hour brought us to the picture-dealer's establishment. He was a small, stout man with a red face and a peppery manner.
