Pseudonym of Elizabeth Linington. Barbara "Elizabeth" Linington (March 11, 1921 – April 5, 1988) was an American novelist. She was awarded runner-up scrolls for best first mystery novel from the Mystery Writers of America for her 1960 novel, Case Pending, which introduced her most popular series character, LAPD Homicide Lieutenant Luis Mendoza. Her 1961 book, Nightmare, and her 1962 novel, Knave of Hearts, another entry in the Mendoza series, were both nominated for Edgars in the Best Novel category. Regarded as the "Queen of the Procedurals," she was one of the first women to write police procedurals—a male-dominated genre of police-story writing. Besides crime, Linington also took interest in archaeology, the occult, gemstones, antique weapons and languages. Linington was also a conservative political activist who was an active member of the John Birch Society
