Anna Raymond Massey was an English actress. She won a BAFTA Best Actress Award for the role of Edith Hope in the 1986 TV adaptation of Anita Brookner's novel Hotel du Lac, a role that one of her co-stars, Julia McKenzie, has said "could have been written for her". Massey is also well-known for her role in Alfred Hitchcock's Frenzy (1972) as a barmaid who becomes involved with a suspected killer. She performed over one hundred character roles in British film and television.
