Morrison achieved international acclaim in 1932 with the publication, under her pen name March Cost, of her first novel
A Man Named Luke. In 1939, she began work on her monumental biographical novel about the great French nineteenth century actress Rachel. She wrote most of it during the
London Blitz, and was forced to move from both a gutted flat and bombed house with her manuscript and research books in a battered suitcase. Further biographical novels followed, including of
Aimée du Buc de Rivéry, a first cousin of the
Empress Josephine, who was rumoured to have been the same person as
Nakşidil Sultan who married the Sultan of Turkey; and of the 18th‐century mystic
Emanuel Swedenborg. == Personal life==
