Helen Clark MacInnes

Helen Clark MacInnes (born October 7, 1907, Glasgow, Scotland—died September 20, 1985, New York, New York, U.S.) was a Scottish-born American novelist, known for her taut, realistic espionage thrillers.

MacInnes received an M.A. from the University of Glasgow in 1928 and remained at the university for a year afterward as a special cataloger in the library. After a year of library work she entered the School of Librarianship of University College, London, in 1930, graduating the following year. In 1932 she married Gilbert Highet. Over the next several years they collaborated on a number of translations from German. In 1938, after Highet had taught for a year at Columbia University, he accepted a permanent post there, and the family settled in New York City. (They became naturalized U.S. citizens in 1951.)

A short time after moving to New York, MacInnes began her first book, Above Suspicion (1941), a tale of espionage in Nazi Europe. It was an immediate success, widely praised for its suspense and humour, and it was made into a motion picture in 1943. Assignment in Brittany followed in 1942 and was also made into a movie the following year. While Still We Live (1944) and Horizon (1945) were both suspenseful tales of World War II. Friends and Lovers (1947), a love story, was followed by a series of thrillers concerning international intrigue and Cold War tension, including Neither Five nor Three (1951), Pray for a Brave Heart (1955), Decision at Delphi (1960), The Venetian Affair (1963), Message from Málaga (1971), and Prelude to Terror (1978). Her final book, Ride a Pale Horse, appeared in 1984.

Almost all of MacInnes’s books were best-sellers, and they were frequently translated and reissued; several more were made into motion pictures. Critics and readers alike noted MacInnes’s skillful and credible portrayal of espionage and the characters involved in it. She credited her success to thorough research and her interest in international politics.
