"Or a fiend. Well, it was not to talk of my poor lad that I asked you to come, Mr. Holmes."

"Dr. Watson and I are at your service."

"There have been some very strange happenings. I have been in this house more than a year now, and as I wished to lead a retired life I have seen little of my neighbours. Three days ago I had a call from a man who said that he was a house agent. He said that this house would exactly suit a client of his and that if I would part with it money would be no object. It seemed to me very strange, as there are several empty houses on the market which appear to be equally eligible, but naturally I was interested in what he said. I therefore named a price which was five hundred pounds more than I gave. He at once closed with the offer, but added that his client desired to buy the furniture as well and would I put a price upon it. Some of this furniture is from my old home, and it is, as you see, very good, so that I named a good round sum. To this also he at once agreed. I had always wanted to travel, and the bargain was so good a one that it really seemed that I should be my own mistress for the rest of my life.

"Yesterday the man arrived with the agreement all drawn out. Luckily I showed it to Mr. Sutro, my lawyer, who lives in Harrow. He said to me, 'This is a very strange document. Are you aware that if you sign it you could not legally take anything out of the house—not even your own private possessions?' When the man came again in the evening I pointed this out, and I said that I meant only to sell the furniture.

"'No, no; everything,' said he.

"'But my clothes? My jewels?'

"'Well, well, some concession might be made for your personal effects. But nothing shall go out of the house unchecked. My client is a very liberal man, but he has his fads and his own way of doing things. It is everything or nothing with him.'

"'Then it must be nothing,' said I. And there the matter was left, but the whole thing seemed to me to be so unusual that I thought——"

Here we had a very extraordinary interruption.

Holmes raised his hand for silence. Then he strode across the room, flung open the door, and dragged in a great gaunt woman whom he had seized by the shoulder. She entered with ungainly struggles, like some huge awkward chicken, torn squawking out of its coop.
