In the early dawn I woke with a start and was surprised to find him standing by my bedside, clad in a rude sailor dress with a pea-jacket and a coarse red scarf round his neck.

“I am off down the river, Watson,” said he. “I have been turning it over in my mind, and I can see only one way out of it. It is worth trying, at all events.”

“Surely I can come with you, then?” said I.

“No; you can be much more useful if you will remain here as my representative. I am loath to go, for it is quite on the cards that some message may come during the day, though Wiggins was despondent about it last night. I want you to open all notes and telegrams, and to act on your own judgment if any news should come. Can I rely upon you?”

“Most certainly.”

“I am afraid that you will not be able to wire to me, for I can hardly tell yet where I may find myself. If I am in luck, however, I may not be gone so very long. I shall have news of some sort or other before I get back.”

I had heard nothing of him by breakfast time. On opening the Standard, however, I found that there was a fresh allusion to the business.

With reference to the Upper Norwood tragedy [it remarked] we have reason to believe that the matter promises to be even more complex and mysterious than was originally supposed. Fresh evidence has shown that it is quite impossible that Mr. Thaddeus Sholto could have been in any way concerned in the matter. He and the housekeeper, Mrs. Bernstone, were both released yesterday evening. It is believed, however, that the police have a clue as to the real culprits, and that it is being prosecuted by Mr. Athelney Jones, of Scotland Yard, with all his well-known energy and sagacity. Further arrests may be expected at any moment.

“That is satisfactory so far as it goes,” thought I. “Friend Sholto is safe, at any rate. I wonder what the fresh clue may be, though it seems to be a stereotyped form whenever the police have made a blunder.”

I tossed the paper down upon the table, but at that moment my eye caught an advertisement in the agony column. It ran in this way:

Lost—Whereas Mordecai Smith, boatman, and his son Jim, left Smith’s Wharf at or about three o’clock last Tuesday morning in the steam launch Aurora, black with two red stripes, funnel black with a white band, the sum of five pounds will be paid to anyone who can give information to Mrs. Smith, at Smith’s Wharf, or at 221B, Baker Street, as to the whereabouts of the said Mordecai Smith and the launch Aurora.

This was clearly Holmes’s doing. The Baker Street address was enough to prove that. It struck me as rather ingenious because it might be read by the fugitives without their seeing in it more than the natural anxiety of a wife for her missing husband.

It was a long day. Every time that a knock came to the door or a sharp step passed in the street, I imagined that it was either Holmes returning or an answer to his advertisement. I tried to read, but my thoughts would wander off to our strange quest and to the ill-assorted and villainous pair whom we were pursuing. Could there be, I wondered, some radical flaw in my companion’s reasoning? Might he not be suffering from some huge self-deception? Was it not possible that his nimble and speculative mind had built up this wild theory upon faulty premises? I had never known him to be wrong, and yet the keenest reasoner may occasionally be deceived. He was likely, I thought, to fall into error through the over-refinement of his logic—his preference for a subtle and bizarre explanation when a plainer and more commonplace one lay ready to his hand. Yet, on the other hand, I had myself seen the evidence, and I had heard the reasons for his deductions. When I looked back on the long chain of curious circumstances, many
