With The Prime of Miss Jean Brodie (1961), later adapted into a successful play and film, Spark became an international celebrity and began to live half her life in New York City. John Updike, Tennessee Williams, Evelyn Waugh, and Graham Greene applauded her work. She had an office at The New Yorker and became friends with Shirley Hazzard and W. H. Auden. Spark ultimately settled in Italy, where for more than thirty years--until her death in 2006--she shared a house with the artist Penelope Jardine.

Spark gave Martin Stannard full access to her papers. He interviewed her many times as well as her colleagues, friends, and family members. The result is an indelible portrait of one of the most significant and emotionally complicated writers of the twentieth century. Stannard presents Spark as a woman of strong feeling, sharp wit, and unabashed ambition, determined to devote her life to her art. Muriel Spark promises to become the definitive biography of a literary icon.
