A Bag of Marbles (French: Un sac de billes) is a Second World War autobiographical novel by the French Jewish author Joseph Joffo. It tells the story of his flight, as a small boy, with his brother Maurice to escape from Nazi occupied France to the Zone Libre. Joffo was refused by many publishers before being encouraged by the newly founded publishing house Éditions Jean-Claude Lattès to get the help of an editor to publish the text. The book was a phenomenal best-seller, being made into a major film two years later.
