“Data!data!data!" he cried impatiently. "I can't make bricks without clay.”

“It is a capital mistake to theorize before one has data. Insensibly one begins to twist facts to suit theories, instead of theories to suit facts.”

“I examine the data, as an expert, and pronounce a specialist's opinion. I claim no credit in such cases. My name figures in no newspaper. The work itself, the pleasure of finding a filed for my peculiar powers, is my highest reward.”

“What the deuce is it to me?" he interrupted impatiently: "you say that we go round the sun. If we went round the moon it would not make a pennyworth of difference to me or to my work.”

“Excellent!" I cried. "Elementary," said he.”

“A large and comfortable double-bedded room had been placed at our disposal, and I was quickly between the sheets, for I was weary after my night of adventure. Sherlock Holmes was a man, however, who when he had an unsolved problem upon his mind would go for days, and even for a week, without rest, turning it over, rearranging his facts, looking at it from every point of view, until he had either fathomed it, or convinced himself that his data were insufficient. It was soon evident to me that he was now preparing for an all-night sitting. He took off his coat and waistcoat, put on a large blue dressing-gown, and then wandered about the room collecting pillows from his bed, and cusions from the sofa and armchairs. With these he constructed a sort of Eastern divan, upon which he perched himself cross-legged, with an ounce of shag tobacco and a box of matches laid out in front of him. In the dim light of the lamp I saw him sitting there, an old brier pipe between his lips, his eyes fixed vacantly upon the corner of the ceiling, the blue smoke curling up from him, silent, motionless, with the light shining upon his strong-set aquiline features. So he sat as I dropped off to sleep, and so he sat when a sudden ejaculation caused me to wake up, and I found the summer sun shining into the apartment. The pipe was still between his lips, the smoke still curled upwards, and the room was full of a dense tobacco haze, but nothing remained of the heap of shag which I had seen upon the previous night.'Awake, Watson?' he asked.'Yes.''Game for a morning drive?''Certainly.''Then dress. No one is stirring yet, but I know where the stable-boy sleeps, and we shall soon have the trap out.”

“Come, Watson, come!" he cried. The game is afoot.”
