"He'd get the sack; it would wreck him. His people are not very well off; he told me once that before he came here he was getting a quid a week in London—and living on it."

Darwen spread out his hands with an almost continental gesture. "My dear chap, you're following quite an erroneous line of reasoning, it's rather a pet theory of mine, as an engineer. However, tell the doctor you had an accident in the execution of your duty, etc., etc. No need for it to get round at all. He'll forget all about you as soon as you've paid him his fee."

Carstairs was thoughtful, he puffed his pipe in silence for some minutes, then he stood up. "Alright, let's go to two while we're about it, then we can check 'em one on the other. I'm going to bed."

"Shall I get alright again in a month?" Carstairs asked.

"Probably, most probably."

"What are you going to do?" Darwen asked when they got outside. "Ask for a month?"
