Graham Greene called him ‘the greatest novelist of my generation’; Hilaire Belloc thought he was possessed by the devil. Written with the family’s support and drawing on unpublished letters, diaries and memoirs, this new biography reassesses the life and career of the author of Brideshead Revisited: his troubled relationship with his father, his early homosexual affairs, his conversion to Catholicism, wartime service, happy second marriage, drug-induced madness, and his sharp tongue and devastating wit.
