IN GLANCING over the somewhat incoherent series of Memoirs with which I have endeavoured to illustrate a few of the mental peculiarities of my friend Mr. Sherlock Holmes, I have been struck by the difficulty which I have experienced in picking out examples which shall in every way answer my purpose. For in those cases in which Holmes has performed some tour de force of analytical reasoning, and has demonstrated the value of his peculiar methods of investigation, the facts themselves have often been so slight or so commonplace that I could not feel justified in laying them before the public. On the other hand, it has frequently happened that he has been concerned in some research where the facts have been of the most remarkable and dramatic character, but where the share which he has himself taken in determining their causes has been less pronounced than I, as his biographer, could wish. The small matter which I have chronicled under the heading of “A Study in Scarlet,” and that other later one connected with the loss of the Gloria Scott, may serve as examples of this Scylla and Charybdis which are forever threatening the historian. It may be that in the business of which I am now about to write the part which my friend played is not sufficiently accentuated; and yet the whole train of circumstances is so remarkable that I cannot bring myself to omit it entirely from this series.
It had been a close, rainy day in October. Our blinds were half-drawn, and Holmes lay curled upon the sofa, reading and re-reading a letter which he had received by the morning post. For myself, my term of service in India had trained me to stand heat better than cold, and a thermometer of ninety was no hardship. But the paper was uninteresting. Parliament had risen. Everybody was out of town, and I yearned for the glades of the New Forest or the shingle of Southsea. A depleted bank account had caused me to postpone my holiday, and as to my companion, neither the country nor the sea presented the slightest attraction to him. He loved to lie in the very centre of five millions of people, with his filaments stretching out and running through them, responsive to every little rumour or suspicion of unsolved crime. Appreciation of nature found no place among his many gifts, and his only change was when he turned his mind from the evil-doer of the town to track down his brother of the country.
Finding that Holmes was too absorbed for conversation, I had tossed aside the barren paper, and, leaning back in my chair I fell into a brown study. Suddenly my companion’s voice broke in upon my thoughts.
“You are right, Watson,” said he. “It does seem a very preposterous way of settling a dispute.”
“Most preposterous!” I exclaimed, and then, suddenly realizing how he had echoed the inmost thought of my soul, I sat up in my chair and stared at him in blank amazement.
“What is this, Holmes?” I cried. “This is beyond anything which I could have imagined.”
He laughed heartily at my perplexity.
“You remember,” said he, “that some little time ago, when I read you the passage in one of Poe’s sketches, in which a close reasoner follows the unspoken thoughts of his companion, you were inclined to treat the matter as a mere tour de force of the author. On my remarking that I was constantly in the habit of doing the same thing you expressed incredulity.”
“Oh, no!”
“Perhaps not with your tongue, my dear Watson, but certainly with your eyebrows. So when I saw you throw down your paper and enter upon a train of thought, I was very happy to have the opportunity of reading it off, and eventually of breaking into it, as a proof that I had been in rapport with you.”
