“I’ll tell it ye from the beginning,” he said. “My time is from ten at night to six in the morning. At eleven there was a fight at the ‘White Hart’; but bar that all was quiet enough on the beat. At one o’clock it began to rain, and I met Harry Murcher—him who has the Holland Grove beat—and we stood together at the corner of Henrietta Street a-talkin’. Presently—maybe about two or a little after—I thought I would take a look round and see that all was right down the Brixton Road. It was precious dirty and lonely. Not a soul did I meet all the way down, though a cab or two went past me. I was a strollin’ down, thinkin’ between ourselves how uncommon handy a four of gin hot would be, when suddenly the glint of a light caught my eye in the window of that same house. Now, I knew that them two houses in Lauriston Gardens was empty on account of him that owns them who won’t have the drains seen to, though the very last tenant what lived in one of them died o’ typhoid fever. I was knocked all in a heap therefore at seeing a light in the window, and I suspected as something was wrong. When I got to the door——”

“You stopped, and then walked back to the garden gate,” my companion interrupted. “What did you do that for?”

Rance gave a violent jump, and stared at Sherlock Holmes with the utmost amazement upon his features.

“Why, that’s true, sir,” he said; “though how you come to know it, Heaven only knows. Ye see, when I got up to the door it was so still and so lonesome, that I thought I’d be none the worse for some one with me. I ain’t afeared of anything on this side o’ the grave; but I thought that maybe it was him that died o’ the typhoid inspecting the drains what killed him. The thought gave me a kind o’ turn, and I walked back to the gate to see if I could see Murcher’s lantern, but there wasn’t no sign of him nor of anyone else.”

“There was no one in the street?”

“Not a livin’ soul, sir, nor as much as a dog. Then I pulled myself together and went back and pushed the door open. All was quiet inside, so I went into the room where the light was a-burnin’. There was a candle flickerin’ on the mantelpiece—a red wax one—and by its light I saw——”

“Yes, I know all that you saw. You walked round the room several times, and you knelt down by the body, and then you walked through and tried the kitchen door, and then——”

John Rance sprang to his feet with a frightened face and suspicion in his eyes. “Where was you hid to see all that?” he cried. “It seems to me that you knows a deal more than you should.”

Holmes laughed and threw his card across the table to the constable. “Don’t get arresting me for the murder,” he said. “I am one of the hounds and not the wolf; Mr. Gregson or Mr. Lestrade will answer for that. Go on, though. What did you do next?”
