Arthur looked up, startled. “I’ve never met anyone with such terrible manners,” he said. “Come off it, Arthur.”

But Arthur was genuinely shocked. “How would you like it if I was to ask you how much money you had in the bank?” he said indignantly.

“All right. Tell me something else, then. How did it start? The Sergeant kept very quiet about that. What happened in the end to that Markos brigade you both commanded?”

Arthur shook his head sadly. “Always asking questions. I suppose it’s being a lawyer.”

“I have an inquiring mind.”

“Just plain nosy-parkering, my mother would have called it.”
