"It is possible."
"And you thought he was pulled back?"
"He disappeared so suddenly."
"He might have leaped back. You did not see anyone else in the room?"
"No, but this horrible man confessed to having been there, and the Lascar was at the foot of the stairs."
"Quite so. Your husband, as far as you could see, had his ordinary clothes on?"
"But without his collar or tie. I distinctly saw his bare throat."
"Had he ever spoken of Swandam Lane?"
"Had he ever showed any signs of having taken opium?"
"Thank you, Mrs. St. Clair. Those are the principal points about which I wished to be absolutely clear. We shall now have a little supper and then retire, for we may have a very busy day to-morrow."
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 cushions 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 briar 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 upward, 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.
