"Well, sir, it's this lonely, silent house and the queer thing in the kitchen. Then when you tapped at the window I thought it had come again."

"That what had come again?"

"The devil, sir, for all I know. It was at the window."

"What was at the window, and when?"

"It was just about two hours ago. The light was just fading. I was sitting reading in the chair. I don't know what made me look up, but there was a face looking in at me through the lower pane. Lord, sir, what a face it was! I'll see it in my dreams."

"Tut, tut, Walters. This is not talk for a police-constable."

"I know, sir, I know; but it shook me, sir, and there's no use to deny it. It wasn't black, sir, nor was it white, nor any colour that I know but a kind of queer shade like clay with a splash of milk in it. Then there was the size of it--it was twice yours, sir. And the look of it--the great staring goggle eyes, and the line of white teeth like a hungry beast. I tell you, sir, I couldn't move a finger, nor get my breath, till it whisked away and was gone. Out I ran and through the shrubbery, but thank God there was no one there."

"If I didn't know you were a good man, Walters, I should put a black mark against you for this. If it were the devil himself a constable on duty should never thank God that he could not lay his hands upon him. I suppose the whole thing is not a vision and a touch of nerves?"

"That, at least, is very easily settled," said Holmes, lighting his little pocket lantern. "Yes," he reported, after a short examination of the grass bed, "a number twelve shoe, I should say. If he was all on the same scale as his foot he must certainly have been a giant."

"What became of him?"
