"None."

　　"But surely you or the girl enter his room of a morning?""No, sir; he looks after himself entirely."

　　"Dear me! that is certainly remarkable. What about his luggage?""He had one big brown bag with him- nothing else."

　　"Well, we don't seem to have much material to help us. Do you saynothing has come out of that room- absolutely nothing?"The landlady drew an envelope from her bag, from it she shook outtwo burnt matches and a cigarette-end upon the table.

　　"They were on his tray this morning. I brought them because I hadheard that you can read great things out of small ones."Holmes shrugged his shoulders.

　　"There is nothing here," said he. "The matches have, of course, beenused to light cigarettes. That is obvious from the shortness of theburnt end. Half the match is consumed in lighting a pipe or cigar. Butdear me! this cigarette stub is certainly remarkable. The gentlemanwas bearded and moustached, you say?"

　　"Yes, sir."

　　"I don't understand that. I should say that only a clean-shavenman could have smoked this. Why, Watson, even your modest moustachewould have been singed."

　　"A holder?" I suggested.

　　"No, no; the end is matted. I suppose there could not be twopeople in your rooms, Mrs. Warren?"

　　"No, sir. He eats so little that I often wonder it can keep lifein one."

　　"Well, I think we must wait for a little more material. After all,you have nothing to complain of. You have received your rent and he isnot a troublesome lodger, though he is certainly an unusual one. Hepays you well. and if he choses to lie concealed it is no directbusiness of yours. We have no excuse for an intrusion upon his privacyuntil we have some reason to think that there is a guilty reason forit. I've taken up the matter, and I won't lose sight of it. Reportto me if anything fresh occurs, and rely upon my assistance if itshould be needed.

　　"There are certainly some points of interest in this case,Watson," he remarked when the landlady had left us. "It may, ofcourse, be trivial- individual eccentricity; or it may be very muchdeeper than appears on the surface. The first thing that strikes oneis the obvious possibility that the person now in the rooms may beentirely different from the one who engaged them."

　　"Why should you think so?"
