"It only makes it even surer; no, it can't do that, but it leaves it as sure as it was. Of course, the name in the 'Where is it?' is not the man's real name; not the name he goes by, anyhow."
"So it seemed possible to me."
"Then you were wrong. There is no question of possibility. It is dealing with absolute certainties. Now satisfy my curiosity. I have not much, but I have some."
"Bit by bit," said Harry. "Have you ever heard of a Dr. Godfrey, heart specialist, I take it, who lives at 32 Wimpole Street?"
"Never. But Wimpole Street is just round the corner. I imagine he will have a plate on his door. I thought your heart was in a parlous state."
"Oh, don't be funny," said Harry, "but come along."
Geoffrey got up.
"Shall I have to hold your hand?" he asked.
"No; I am not going to consult him. Indeed, there is no mystery about the whole matter. Simply Dr. Godfrey is my uncle's doctor, and he consulted him the other day about his heart. I happened to look out the doctor's address in his 'Where is it?' and found the name in inverted commas. Oh! by the way, there is a red book by you. Look out 32 Half Moon Street. Does Dr. Godfrey live there?"
Geoffrey turned up the street.
