Cyril Connollly (1903-1974) was a novelist, aesthete, wit, patron of unknown causes. In Kenneth Tynan's words, he was intellectually, a logbook of his generation's voyages and discoveries. This is his biography. Connolly was the author of eight books, including Enemies of Promise and The Unquiet Grave. For half a century he was a reviewer and critic, and the founder and editor of the magazine Horizon. But in his own view he was a failure. This biography accesses Connolly's life and work and establishes the nature of his achievement and legacy.
