Christopher Isherwood greeted the Sixties in a mood of high optimism. “I think in some ways this is the happiest period of my life,” he wrote to Stephen Spender in January 1960. Isherwood’s diaries were clearly intended for publication. In a sense they complete a multi-volume autobiographical project describing his relationships with the most important people in his life. Although the diaries present a highly detailed and personal account of the various worlds in which Isherwood moved from 1939 onwards, their principal subject after 1953 is his relationship with Bachardy. The present volume opens on August 27 1960, the day after Isherwood’s 56th birthday.
