Elizabeth Linington was a prolific novelist and writer, producing about 80 books in her career. Called the "queen of the procedurals," she was one of the first American women to write police procedurals — a male-dominated genre before that. Her novel Case Pending (1960), which introduced her most popular series character, Lieutenant Luis Mendoza, head of the Los Angeles Police Department's homicide squad, was awarded runner-up for Best First Mystery Novel from the Mystery Writers of America. Nightmare (1961) and Knave of Hearts (1962), in the same series, both were nominated for Edgar Awards in the Best Novel category. Her interests in archaeology, the occult, gemstones, antique weapons, and languages were reflected in her works. As noted below, she wrote under numerous pen names.
