Dorothy B. Hughes (10 August 1904 – 6 May 1993) was an American crime writer and literary critic. Hughes wrote fourteen crime and detective novels, primarily in the hardboiled and noir styles, and is best known for the novels In a Lonely Place (1947) and Ride the Pink Horse (1946).
Born Dorothy Belle Flanagan in Kansas City, Missouri, she studied journalism and after graduating from the University of Missouri with a B.J. degree in 1924 worked in that field in Missouri, New Mexico, and New York. She did graduate work in journalism at the University of New Mexico and at Columbia University but did not receive a degree from either institution.
Hughes’s first published book, Dark Certainty (1931), a volume of poetry, won the Yale Series of Younger Poets Competition.
In 1940, she published her first mystery novel, The So Blue Marble. She published eight more mystery novels in the 1940s. She also wrote a history of the University of New Mexico and a critical study of writer Erle Stanley Gardner. In 1951 she received an Edgar Award from the Mystery Writers of America in the category of Outstanding Mystery Criticism, and in 1978 she was given the MWA's Grand Master award.
Hughes acknowledged the influence of such writers as Eric Ambler, Graham Greene, and William Faulkner. Her writing style and suspenseful plots exemplified the hardboiled genre of crime and detective novels, and her literary career associates her with other female crime writers of the 1940s and 1950s, such as Margaret Millar, Vera Caspary, Elizabeth Sanxay Holding, and Olive Higgins Prouty.
