"Roberts," he said, "there is no need that you should be ground to powder."
"I don't understand."
"I hope you never will. Your wife doesn't look very strong. Why don't you give her a change?"

"Hang most workers! Your wife wants a change."
"I haven't got the money, anyhow."
"Then there's an end of it."
The Colonel rose, and they made for the drawing room.
Philip detained his companion for a moment.
