“I see. Now I wonder if I can see Mrs. Havering?”

“She’s upstairs, sir. Shall I tell her?”

“If you please. Tell her that Mr. Havering is outside with Inspector Japp, and that the gentleman he has brought back with him from London is anxious to speak to her as soon as possible.”

“Very good, sir.”

I was in a fever of impatience to get at all the facts. Japp had two or three hours’ start of me, and his anxiety to be gone made me keen to be close at his heels.
