The Scapegoat is a 1957 novel by Daphne du Maurier. In a bar in France, a lonely English academic on holiday meets his double, a French aristocrat who gets him drunk, swaps identities and disappears, leaving the Englishman to sort out the Frenchman's extensive financial and family problems. The story has been the basis of two films: one in 1959 starring Alec Guinness and Bette Davis and one in 2012 starring Matthew Rhys. Source: Wikipedia (en)
