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?"

"He seems to have broken through the shrubbery and made for the road."

"Well," said the inspector with a grave and thoughtful face, "whoever he may have been, and whatever he may have wanted, he's gone for the present, and we have more immediate things to attend to. Now, Mr. Holmes, with your permission, I will show you round the house."

The various bedrooms and sitting-rooms had yielded nothing to a careful search. Apparently the tenants had brought little or nothing with them, and all the furniture down to the smallest details had been taken over with the house. A good deal of clothing with the stamp of Marx and Co., High Holborn, had been left behind. Telegraphic inquiries had been already made which showed that Marx knew nothing of his customer save that he was a good payer. Odds and ends, some pipes, a few novels, two of them in Spanish, an old-fashioned pinfire revolver, and a guitar were among the personal property.

"Nothing in all this," said Baynes, stalking, candle in hand, from room to room. "But now, Mr. Holmes, I invite your attention to the kitchen."

It was a gloomy, high-ceilinged room at the back of the house, with a straw litter in one corner, which served apparently as a bed for the cook. The table was piled with half-eaten dishes and dirty plates, the debris of last night's dinner.

"Look at this," said Baynes. "What do you make of it?"

He held up his candle before an extraordinary object which stood at the back of the dresser. It was so wrinkled and shrunken and withered that it was difficult to say what it might have been. One could but say that it was black and leathery and that it bore some resemblance to a dwarfish, human figure.
