In Friend and Foe, Frederick Harris examines the life and works of French authors Marcel Proust and Andre Gide. Proust and Gide clearly defined French literature in the first part of the twentieth century. This book contains the whole of correspondence between Proust and Gide, some letters translated in English for the first time. By looking at Proust and Gide simultaneously, looking at Proust and the whole coterie of writers and critics that gathered around Gide at the Nouvelle Revue Francaise (NRF), Harris provides a new context in which to assess both Proust and Gide. It forces consideration in a more incisive way of the key issues in both their careers: the Dreyfus Affair, World War I, homosexuality, and their art.
