Born in 1918 into a working-class Edinburgh family, Muriel Spark ended as the epitome of literary chic, one of the great writers of the twentieth century.

It is a Cinderella story, the first thirty-nine years of which she presented in her autobiography, Curriculum Vitae (1992), politely blurring the intensity of her darker moments: her relations with her brother, mother, son, husband; a terrifying period of hallucinations and subsequent depression; and the disastrously misplaced love she had felt for two men she had wanted to marry, Howard Sergeant and Derek Stanford.

Aged nineteen, Spark left Scotland to marry in Southern Rhodesia, escaping back to Britain on a troopship in 1944 after her divorce. Her son returned in 1945 to be brought up by her parents in Edinburgh while she established herself as a poet and critic in London.
