Read it through once

But practice and principle are never reduced to perfect agreement. One is always marauding the other's territory; nevertheless for several months principle distinctly held the upper hand; William refused over and over again to make bets with comparative strangers, but the day came when his principle relaxed, and he took the money of a man whom he thought was all right. It was done on the impulse of the moment, but the two half-crowns wrapped up in the paper, with the name of the horse written on the paper, had hardly gone into the drawer than he felt that he had done wrong. He couldn't tell why, but the feeling came across him that he had done wrong in taking the man's money--a tall, clean-shaven man dressed in broadcloth. It was too late to draw back. The man had finished his beer and had left the bar, which in itself was suspicious.
