The Tenth Man; Graham Greene

In a prison in Occupied France during the Second World War, the order is given that every tenth inmate is to be executed. Louis Chavel, a rich lawyer, draws the short straw and barters everything he owns to exchange places with another man and survive. Destitute but free, Chavel later returns to the house that he sold for his life, where he must face the consequences of his cowardice and seek redemption.
