Amid the droning of the wind there had come the stamping of a horse’s hoofs, and the long grind of a wheel as it rasped against the curb. The cab which I had seen had pulled up at our door.

“What can he want?” I ejaculated, as a man stepped out of it.

“Want? He wants us. And we, my poor Watson, want overcoats and cravats and goloshes, and every aid that man ever invented to fight the weather. Wait a bit, though! There’s the cab off again! There’s hope yet. He’d have kept it if he had wanted us to come. Run down, my dear fellow, and open the door, for all virtuous folk have been long in bed.”

When the light of the hall lamp fell upon our midnight visitor, I had no difficulty in recognizing him. It was young Stanley Hopkins, a promising detective, in whose career Holmes had several times shown a very practical interest.

“Is he in?” he asked, eagerly.
