"He spoke good English, sir, and yet I thought he was a foreigner by his accent." "And he was well dressed?" "Very smartly dressed, sir--quite the gentleman. Dark clothes--nothing you would note." "He gave no name?" "No, sir." "And has had no letters or callers?" "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 say nothing has come out of that room--absolutely nothing?" The landlady drew an envelope from her bag; from it she shook out two burnt matches and a cigarette-end upon the table. "They were on his tray this morning. I brought them because I had heard 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, been used to light cigarettes. That is obvious from the shortness of the burnt end. Half the match is consumed in lighting a pipe or cigar. But, dear me! this cigarette stub is certainly remarkable. The gentleman was bearded and moustached, you say?" "Yes, sir." "I don't understand that. I should say that only a clean-shaven man could have smoked this. Why, Watson, even your modest moustache would have been singed." "A holder?" I suggested. "No, no; the end is matted. I suppose there could not be two people in your rooms, Mrs. Warren?" "No, sir. He eats so little that I often wonder it can keep life in 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 is not a troublesome lodger, though he is certainly an unusual one. He pays you well, and if he chooses to lie concealed it is no direct business of yours. We have no excuse for an intrusion upon his privacy until we have some reason to think that there is a guilty reason for it. I've taken up the matter, and I won't lose sight of it. Report to me if anything fresh occurs, and rely upon my assistance if it should be needed. "There are certainly some points of interest in this case, Watson," he remarked when the landlady had left us. "It may, of course, be trivial--individual eccentricity; or it may be very much deeper than appears on the surface. The first thing that strikes one is the obvious possibility that the person now in the rooms may be entirely different from the one who engaged them." "Why should you think so?"
