British journalist and novelist whose writing, depicting a nightmarish world of neuroses and broken marriages, influenced feminist fiction of the 1960s.

After her graduation from the University of London, she began to write poetry, book reviews, and short stories. She was married to the journalist Charles Dimont; in 1949 they divorced and she married the playwright and author John Mortimer (Mortimer, Sir John) (divorced 1972), with whom she collaborated on the book Daddy's Gone A-Hunting (1958). She is perhaps best known for her novel The Pumpkin Eater (1962), a disturbingly vivid story of a woman whose compulsive anxiety to bear children gradually isolates her from her successive husbands. The novel was turned into a successful film in 1964, its screenplay by Harold Pinter (Pinter, Harold). Her other work includes the novel My Friend Says It's Bullet-Proof (1967) and two autobiographical volumes, About Time (1979) and About Time Too (1993).
