“To Sherlock Holmes she is always the woman. I have seldom heard him mention her under any other name. In his eyes she eclipses and predominates the whole of her sex. It was not that he felt any emotion akin to love for Irene Adler. All emotions, and that one particularly, were abhorrent to his cold, precise but admirably balanced mind. He was, I take it, the most perfect reasoning and observing machine that the world has seen.... And yet there was but one woman to him, and that woman was the late Irene Adler, of dubious and questionable memory.”

“In his eyes she eclipses and predominates the whole of her sex.”

“He was, I take it, the most perfect reasoning and observing machine that the world has seen, but as a lover he would have placed himself in a false position. He never spoke of the softer passions, save with a gibe and a sneer. They were admirable things for the observer- excellent for drawing the veil from men's motives and actions. But for the trained observer to admit such intrusions into his own delicate and finely adjusted temperament was to introduce a distracting factor which might throw a doubt upon all his mental results. Grit in a sensitive instrument, or a crack in one of his own high-power lenses, would not be more disturbing than a strong emotion in a nature such as his.”

“From the first day I met her, she was the only woman to me. Every day of that voyage I loved her more, and many a time since have I kneeled down in the darkness of the night watch and kissed the deck of that ship because I knew her dear feet had trod it. She was never engaged to me. She treated me as fairly as ever a woman treated a man. I have no complaint to make. It was all love on my side, and all good comradeship and friendship on hers. When we parted she was a free woman, but I could never again be a free man.”

“He burst into one of his rare fits of laughter as he turned away from the picture. I have not heard him laugh often, and it has always boded ill to somebody.”

“Her cuisine is limited but she has as good an idea of breakfast as a Scotchwoman."[Sherlock Holmes, on Mrs. Hudson's cooking.]”

“I had no keener pleasure than in following Holmes in his professional investigations, and in admiring the rapid deductions, as swift as intuitions, and yet always founded on a logical basis, with which he unravelled the problems which were submitted to him. I rapidly threw on my clothes, and was ready in a few minutes to accompany my friend down to the sitting-room. A lady dressed in black and heavily veiled, who had been sitting in the window, rose as we entered.'Good morning, madam, said Holmes, cheerily. 'My name is Sherlock Holmes. This is my intimate friend and associate, Dr. Watson, before whom you can speak as freely as before myself.”
