"I am glad you were able to go with the Duke," I said.

He gave a start at my tone and then laughed. "It was very fortunate. I am glad that—you are glad, Christabel."

"I am afraid you must have found it inconvenient to leave him so soon."

"Are you?"

"Had you not better hurry back to him?"

"Yes. I am going straight back from here."

"Don't let me keep you, pray."

"Very well."

What can you do with a man who refuses in this way to be teased, but just accepts what you say with preposterous good humour? I shrugged my shoulders. "Why don't you go then?"

"That is exactly it. Why? Of course you can't guess such an abstruse problem! It's altogether beyond you; but try. I should like to hear you making a number of ingeniously wrong guesses. Now, what reason can I possibly have for being here?"
