Barbara "Elizabeth" Linington was a pioneering American mystery writer best known for her police procedurals, a genre dominated by male authors during her career. Under her own name and pseudonyms such as Dell Shannon, Lesley Egan, and Anne Blaisdell, she authored numerous novels, including the acclaimed "Case Pending," which introduced her signature character, LAPD Homicide Lieutenant Luis Mendoza. The novel earned her a runner-up scroll for best first mystery novel from the Mystery Writers of America. Her works "Nightmare" and "Knave of Hearts," both part of the Mendoza series, received Edgar Award nominations for Best Novel, cementing her reputation as the "Queen of Procedurals."
Linington's writing was distinguished by its meticulous attention to police work and its authentic portrayal of investigative procedures. Beyond crime fiction, her interests spanned archaeology, the occult, gemstones, antique weapons, and languages, which occasionally influenced her storytelling. Born in Aurora, Illinois, on March 11, 1921, she spent much of her career under the representation of literary agent Barthold Fles. Linington passed away on April 5, 1988, in Arroyo Grande, California, leaving behind a legacy as one of the first women to excel in police procedural fiction.
