Mr. Arthur’s low forehead creased with the effort of thinking. “You see, it’s confidential, that’s the trouble, Mr. Carey,” he said unhappily.

“So you explained. But if it’s so confidential that you can’t talk about it, you’d better go home and let me get some sleep, hadn’t you?”

“Now, don’t talk like that, Mr. Carey. I’m doing my best. Look! If you were to tell me what you want to know about this chap for, I could tell certain persons who might be able to help you.”

“What persons?”

“Persons with information to give.”

“You mean information to sell, don’t you?”

“I said give.”

George examined his guest thoughtfully. “You’re British, aren’t you, Arthur?” he said after a moment. “Or is that confidential?”

Arthur grinned. “Want to hear me speak Greek? I speak it like a native.”

“All right, then. You’re a citizen of the world, then, eh?”
