Paddington district with a view toward purchasing it. Much as I have enjoyed accompanying my friend upon his adventures, this was one which I should have to forego.
Holmes returned late from Surrey, and I did not see him until breakfast the next morning. As often he was when on a case, he was rather uncommunicative, and my attempts to probe the matter were met with monosyllables, except at the very last. "Most unusual," he said, as if to himself. "Most singular indeed."
"What?" I asked, eager to listen now that it appeared that Holmes was ready to break his silence.
"The tracks, Watson," he said. "The tracks. Not man, nor beast, but definitely tracks." He looked at his pocket-watch. "Well, I must be off. Time enough for cogitation when I have more facts."
"But where are you going?"
Holmes laughed. "My dear Watson, I have in my time amassed a bit of knowledge of various matters which would be considered most recherch茅 to laymen. But I fear that, upon occasion, even I must consult with an expert."
"Then whom?"
"Why, I go to see Professor Huxley," he answered, and was out the door before I could ask what query he might have for the eminent biologist.
He was absent from Baker Street all afternoon. When he returned after suppertime I was anxious to ask how his interview with the esteemed professor had gone.
"Ah, Watson, even I make my occasional mistake. I should have telegraphed first. As it was, Professor Huxley had just left London, and is not to return for a week." He took out his pipe, inspected it for a moment, then set it aside and rang for Mrs. Hudson to bring in some supper. "But in this case, my journey was not in vain. I had a most delightful discussion with the professor's prot茅g茅, a Mr. Wells by name. A Cockney lad, son of a shop-keeper and no more than twenty-two, unless I miss my guess, but a most remarkable man nonetheless. Interested in a wide variety of fields, and I venture to say that in whatever field he chooses, he will outshine even his esteemed teacher. Quite an interesting conversation we had, and a most useful one."
"But what was it that you discussed?" I asked.
Holmes set aside the cold beef that Mrs. Hudson had brought, leaned back in his chair, and shut his eyes. For a while I thought that he had gone to sleep without hearing my question. At last he spoke. "Why, we discussed the planet Mars," he said, without opening his eyes. "And the singular habits of wasps."
It seemed that his researches, whatever they were, led to no distinct conclusion, for when I asked him about the case the next day, he gave no response. That day he stayed in his chambers, and through the closed door I heard only the intermittent voice of his violin speaking in its melancholy, unfathomable tongue.
I have perhaps mentioned before that my friend would habitually have more than one case on which he worked at any one time. It appeared that over the next few evenings he was about on another one, for I found him dressing to go out at a late hour.
"Another case, Holmes?" I asked.
"As you can see, Watson," he replied. He indicated his less-than-respectable outfit and the threadbare workman's jacket he was pulling on over it. "Duty calls at all hours. I shan't be more than a few hours, I expect."
"I am ready to assist."
"Not in this one, my dear friend. You may stay home tonight."
"Is there danger?"
"Danger?" He seemed surprised, as if the thought hadn't occurred to him. "Danger? Oh, perhaps a slight bit."
"You know that I would not hesitate . . . "
"My dear doctor," he said, and smiled. "Let me assure you that I am not worried on that score. No, it is that I go to the East End . . . "
The East End of London was no place for gentlemen, with slaughterhouses and tenements of the lowest order; a place for drunkards, sailors, Chinese and Indian laborers, and ruffians of all sorts. Nevertheless I was quite willing to brave much worse, if necessary, for the sake of Holmes. "Is that all?" I said. "Holmes, I do believe you underestimate me!"
"Ah, Watson . . . " He seemed to reflect for a moment. "No, it would not do. You are soon to be married, and have your wife-to-be to think of." He raised a hand to forestall my imminent objection. "No, not the danger, my friend.
