Downstairs, in the dining-room, Jimmy was smoking cigarettes and reviewing in his mind the peculiarities of the situation, when Ann came in.

"Oh, there you are," said Ann. "I thought you must have gone upstairs."

"I have been having a delightful and entertaining conversation with my old chum, Lord Wisbeach."

"Good gracious! What about?"

"Oh, this and that."

"Not about old times?"

"No, we did not touch upon old times."

"Does he still believe that you are Jimmy Crocker? I'm so nervous," said Ann, "that I can hardly speak."

"I shouldn't be nervous," said Jimmy encouragingly. "I don't see how things could be going better."

"That's what makes me nervous. Our luck is too good to last. We are taking such risks. It would have been bad enough without Skinner and Lord Wisbeach. At any moment you may make some fatal slip. Thank goodness, aunt Nesta's suspicions have been squashed for the time being now that Skinner and Lord Wisbeach have accepted you as genuine. But then you have only seen them for a few minutes. When they have been with you a little longer, they may get suspicious themselves. I can't imagine how you managed to keep it up with Lord Wisbeach. I should have thought he would be certain to say something about the time when you were supposed to be friends in London. We simply mustn't strain our luck. I want you to go straight to aunt Nesta now and ask her to let Jerry come back."
