麻豆约拍

As the film of the best-selling book by Irene Nemirovksy, Suite Francaise, is released in cinemas this week, Witness hears the extraordinary story of the manuscript which lay undiscovered in an old suitcase for more than 50 years after Irene Nemirovsky's death in Auschwitz. We hear from her great-granddaughter, and from the man who eventually published Suite Francaise, Olivier Rubinstein.
