Fred said that the whole thing was extraordinarily queer, and that there must be some explanation of it; but Murray, after being quiet for a minute, began to fidget like a man who has been puzzling over an acrostic, and is beginning to discover what it is all about.

"I was going up to see a dentist, and he wrote that he couldn't see me," I replied.

"And Dennison heard you say that you were going?"
