Seldom does a man find himself face to face with a blacker prospect than that which lay before Philip Sheldon; and yet his manner to-night was not the dull blank apathy of despair. It was the manner of a man whose brain is occupied by busy thoughts; who has some elaborate scheme to map out and arrange before he is called upon to carry his plans into action.

"It would be a good business for me," he muttered, "if I had pluck enough to carry it through."

The fire went out as he sat swinging the poker backwards and forwards. The clocks of Bloomsbury and St. Pancras struck twelve, and still Philip Sheldon pondered and plotted by that dreary hearth. The servants had retired at eleven, after a good deal of blundering with bars and shutters, and unnecessary banging of doors. That unearthly silence peculiar to houses after midnight reigned in Mr. Sheldon's domicile, and he could hear the voices of distant roisterers, and the miauling of neighbouring cats, with a painful distinctness as he sat brooding in his silent room. The fact that a mahogany chiffonier in a corner gave utterance to a faint groan occasionally, as of some feeble creature in pain, afforded him no annoyance. He was superior to superstitious fancies, and all the rappings and scratchings of spirit-land would have failed to disturb his equanimity. He was a strictly practical man—one of those men who are always ready, with a stump of lead-pencil and the back of a letter, to reduce everything in creation to figures.

"I had better read up that business before they come," he said, when he had to all appearance "thought out" the subject of his reverie. "No time so good as this for doing it quietly. One never knows who is spying about in the daytime." He looked at his watch, and then went to a cupboard, where there were bundles of wood and matches and old newspapers,—for it was his habit to light his own fire occasionally when he worked unusually late at night or early in the morning. He relighted his fire now as cleverly as any housemaid in Bloomsbury, and stood watching it till it burned briskly. Then he lit a taper, and went downstairs to the professional torture-chamber. The tall horsehair chair looked unutterably awful in the dim glimmer of the taper, and a nervous person could almost have fancied it occupied by the ghost of some patient who had expired under the agony of the forceps. Mr. Sheldon lighted the gas in a movable branch which he was in the habit of turning almost into the mouths of the patients who consulted him at night. There was a cupboard on each side of the mantelpiece, and it was in these two cupboards that the dentist kept his professional library. His books did not form a very valuable collection, but he kept the cupboards constantly locked nevertheless.
