Maloin has been working all his life for 2,500 measly Francs a month. One day he finds a case full of money, after watching a gangland killing. "I'd have to work a hundred years to make that!", he says. He could send his son to "Polytechnique", he could take his wife to the Riviera, he could escape from the third-rate position he holds in the harbor, he could leave behind his mean brother-in-law who's wearing suit and tie and is working in a bank (and think he's got it made). But Maloin has an uneasy conscience. His colleague always reads some pages of the good book before going to sleep.—dbdumonteil
