“I knew who his publisher was. It is not his only novel, you know. I found out that he had not heard from Italy. Then came Douglas’s sudden death. So long as that other manuscript was in the world there was no safety for me. Of course, it must be among his effects, and these would be returned to his mother. I set the gang at work. One of them got into the house as servant. I wanted to do the thing honestly. I really and truly did. I was ready to buy the house and everything in it. I offered any price she cared to ask. I only tried the other way when everything else had failed. Now, Mr. Holmes, granting that I was too hard on Douglas - and, God knows, I am sorry for it! - what else could I do with my whole future at stake?”

Sherlock Holmes shrugged his shoulders.

“Well, well,” said he, “I suppose I shall have to compound a felony as usual. How much does it cost to go round the world in first-class style?”

“Could it be done on five thousand pounds?”

“Well, I should think so, indeed!”

“Very good. I think you will sign me a check for that, and I will see that it comes to Mrs. Maberley. You owe her a little change of air. Meantime, lady” - he wagged a cautionary forefinger - “have a care! Have a care! You can’t play with edged tools forever without cutting those dainty hands.”
