“No, I think that may be dismissed. I had inquiries made, and there is a launch of that description.”

“Could it have gone up the river?”

“I have considered that possibility too, and there is a search-party who will work up as far as Richmond. If no news comes to-day, I shall start off myself to-morrow, and go for the men rather than the boat. But surely, surely, we shall hear something.”

We did not, however. Not a word came to us either from Wiggins or from the other agencies. There were articles in most of the papers upon the Norwood tragedy. They all appeared to be rather hostile to the unfortunate Thaddeus Sholto. No fresh details were to be found, however, in any of them, save that an inquest was to be held upon the following day. I walked over to Camberwell in the evening to report our ill success to the ladies, and on my return I found Holmes dejected and somewhat morose. He would hardly reply to my questions, and busied himself all evening in an abstruse chemical analysis which involved much heating of retorts and distilling of vapours, ending at last in a smell which fairly drove me out of the apartment. Up to the small hours of the morning I could hear the clinking of his test-tubes which told me that he was still engaged in his malodorous experiment.

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.”
