you have been in London?"
"Why. no, Mr. Holmes. I think not."
"You have not observed anyone follow or watch you?
"I seem to have walked right into the thick of a dime novel," said our visitor. "Why in thunder should arnyone follow or watch me?"
"We are coming to that. You have nothing else to report to us before we go into this matter?"
"Well, it depends upon what you think worth reporting."
"I think anything out of the ordinary routine of life well worth reporting."
Sir Henry smiled.
"I don't know much of British life yet, for I have spent nearly all my time in the States and in Canada. But I hope that to lose one of your
boots is not part of the ordinary routine of life over here.
"You have lost one of your boots?"
