"Dear me, Watson," said Holmes, staring with great curiosity at the slips of foolscap which the landlady had handed to him, "this is certainly a little unusual. Seclusion I can understand; but why print? Printing is a clumsy process. Why not write? What would it suggest, Watson?"
"That he desired to conceal his handwriting."
"But why? What can it matter to him that his landlady should have a word of his writing? Still, it may be as you say. Then, again, why such laconic messages?"
"I cannot imagine."
"It opens a pleasing field for intelligent speculation. The words are written with a broad-pointed, violet-tinted pencil of a not unusual pattern. You will observe that the paper is torn away at the side here after the printing was done, so that the s of 'SOAP' is partly gone. Suggestive, Watson, is it not?"
"Of caution?"
"Exactly. There was evidently some mark, some thumbprint, something which might give a clue to the person's identity. Now, Mrs. Warren, you say that the man was of middle size, dark, and bearded. What age would he be?"
"Youngish, sir not over thirty."
"Well, can you give me no further indications?"
"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 but 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 mustached, 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 mustache 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?"
"Well, apart from this cigarette-end, was it not suggestive that the only time the lodger went out was immediately after his taking the rooms? He came back or someone came back when all witnesses were out of the way. We have no proof that the person who came back was the person who went out. Then, again, the man who took the rooms spoke English well. This other, however, prints 'match' when it should have been 'matches.' I can imagine that the word was taken out of a dictionary, which would give the noun but not the plural. The laconic style may be to conceal the absence of knowledge of English. Yes, Watson, there are good reasons to suspect that there has been a substitution of lodgers."
"But for what possible end?"
"Ah! there lies our problem. There is one rather obvious line of investigation." He took down the great book in which, day by day, he filed the agony columns of the various London journals. "Dear me!" said he, turning over the pages, "what a chorus of groans, cries, and bleatings! What a ragbag of singular happenings! But surely the most valuable hunting-ground that ever was given to a student of the unusual! This person is alone and cannot be approached by letter without a breach of that absolute secrecy which is desired. How is any news or any message to reach him from without? Obviously by advertisement through a newspaper. There seems no other way, and fortunately we need concern ourselves with the one paper only. Here are the Daily Gazette extracts of the last fortnight. 'Lady with a black boa at Prince's Skating Club' that we may pass. 'Surely Jimmy will not break his mother's heart' that appears to be irrelevant. 'If the lady who fainted in the Brixton bus' she does not interest me. 'Every day my heart longs ' Bleat, Watson unmitigated bleat! Ah, this is a little more possible. Listen to this: 'Be patient. Will find some sure means of communication. Meanwhile, this column. G.' That is two days after Mrs. Warren's lodger arrived. It sounds plausible, does it not? The mysterious one could understand English, even if he could not print it. Let us see if we can pick up the trace again. Yes, here we are three days later. 'Am making successful arrangements. Patience and prudence. The clouds will pass. G.' Nothing for a week after that. Then comes something much more definite: 'The path is clearing. If I find chance signal message remember code agreed one A, two B, and so on. You will hear soon. G.' That was in yesterday's paper, and there is nothing in today's. It's all very appropriate to Mrs. Warren's lodger. If we wait a little, Watson, I don't doubt that the affair will grow more intelligible." So it proved; for in the morning I found my friend standing on the hearthrug with his back to the fire and a smile of complete satisfaction upon his face.
"How's this, Watson?" he cried, picking up the paper from the table. " 'High red house with white stone facings. Third floor. Second window left. After dusk. G.' That is definite enough. I think after breakfast we must make a little reconnaissance of Mrs. Warren's neighborhood. Ah, Mrs. Warren! what news do you bring us this morning?"
Our client had suddenly burst into the room with an explosive energy which told of some new and momentous development.
"It's a police matter, Mr. Holmes!" she cried. "I'll have no more of it! He shall pack out of there with his baggage. I would have gone straight up and told him so, only I thought it was but fair to you to take your opinion first. But I'm at the end of my patience, and when it comes to knocking my old man about "
"Knocking Mr. Warren about?"
"Using him roughly, anyway."
"But who used him roughly?"
