Leonard Cyril Deighton (born 18 February 1929, Marylebone, London) is a British military historian, cookery writer, and novelist. He is perhaps most famous for his spy novel The IPCRESS File, which was made into a film starring Michael Caine. Deighton was born in Marylebone, London, in 1929. His father was a chauffeur and mechanic, and his mother was a part-time cook. At the time they lived in Gloucester Place Mews near Baker Street. Deighton's interest in spy stories may have been partially inspired by the arrest of Anna Wolkoff, which he witnessed as an 11-year-old boy. Wolkoff, a British subject of Russian descent, was a Nazi spy. She was detained on 20 May 1940 and subsequently convicted of violating the Official Secrets Act for attempting to pass secret documents to the Nazis. After leaving school, Deighton worked as a railway clerk before performing his National Service, which he spent as a photographer for the Royal Air Force's Special Investigation Branch. After discharge from the RAF, he studied at St Martin's School of Art in London in 1949, and in 1952 won a scholarship to the Royal College of Art, graduating in 1955.
