“It’s a queer business you are sending me on.”

“You are the only man I would trust to do it properly.”

“I will do it all right, but I want to ask you one or two essential questions. Has the lady really got the what d’you call it?”

“She has.”

“I am sorry for her. But how am I to stick to it that she has peppered me, when I have never spoken to her?”

“Do you usually catch that complaint by speaking, booby?”

“No, but one speaks in order to catch it, or while one is catching it.”

“You spent two hours in the dark with her without a word being spoken, and she will see that she gave this fine present to you while she thought she was giving it to another.”

“Ah! I begin to see my way, sir. But if we were in the dark, how was I to know it was she I had to do with?

“Thus: you saw her going in by the garden door, and you marked her unobserved. But you may be sure she won’t ask you any of these questions.”
