English novelist, playwright, and journalist, known particularly for his satiric portrayal of the hedonism of the mid-20th-century upper classes of English society.

Raven was educated at Charterhouse, Surrey, and King's College, Cambridge. He resigned as an officer in the British army to write his first novel, The Feathers of Death (1959). This was followed by the 10-part novel sequence Alms for Oblivion, which includes The Rich Pay Late (1964), Fielding Gray (1967), The Judas Boy (1968), Sound the Retreat (1971), and The Survivors (1976). Some characters reappear in his later seven-book series The First-Born of Egypt, which starts with Morning Star (1984) and ends with The Troubadour (1992).

His television dramatizations—among them Aldous Huxley (Huxley, Aldous)'s Point Counter Point (1968), Anthony Trollope (Trollope, Anthony)'s The Pallisers (1974), Nancy Mitford (Mitford, Nancy)'s Love in a Cold Climate (1980), and Edward and Mrs. Simpson (1980)—reached wide audiences.

Among his other writings are an autobiography, Shadows on the Grass (1982); and memoirs, The Old School (1986) and Birds of Ill-Omen (1989).
