Len Deighton (born 18 February 1929) is an English author known for his novels, works of military history, screenplays and cookery writing. He had a varied career, including as a pastry cook, waiter, co-editor of a magazine, teacher and air steward before writing his first novel in 1962: The IPCRESS File. He continued to produce what his biographer John Reilly considers "stylish, witty, well-crafted novels" in spy fiction, including three trilogies and a prequel featuring Bernard Samson.
