In the mid-1950s, inspired by the success of television's "Dragnet" and a similar British TV series, "Fabian of the Yard", Creasey decided to try a more down-to-earth series of cop stories. Adopting the pseudonym "J.J. Marric", he wrote "Gideon's Day", 1955, in which George Gideon, a high-ranking detective at Scotland Yard, spends a busy day supervising his subordinates' investigations into several unrelated crimes. This novel was the first in a series of more than twenty books which brought Creasey his best critical notices. One entry, "Gideon's Fire", 1961, won an Edgar Award from the Mystery Writers of America for Best Mystery Novel. The Gideon series, more than any other source, helped establish the common procedural plot structure of threading several autonomous story lines through a single novel. Maj Sjöwall and Per Wahlöö planned and wrote the Martin Beck police procedural series of ten books between the 1960s and 1970s, set in Sweden. The series is particularly renowned for its extensive character development throughout the series. Beck himself is gradually promoted from detective in a newly nationalised Swedish police force to Chief Inspector of the National Murder Squad, and the realistic depiction, as well as criticism of the Swedish welfare state at the time whilst the tedium of the police procedural continues in the background, is something still widely used today, with authors such as Jo Nesbø and Stieg Larsson. The books gave rise to the Swedish noir scene, and "The Laughing Policeman" earned a "Best Novel" Edgar Award from the Mystery Writers of America in 1971. The books were translated from Swedish into 35 different languages, and have sold roughly ten million copies. Sjöwall and Wahlöö used black humour extensively in the series, and it is widely recognised as one of the finest police procedural series. A prolific author of police procedurals, whose work has fallen out of fashion in the years since her death, is Elizabeth Linington writing under her own name, as well as "Dell Shannon" and "Lesley Egan." Linington reserved her Dell Shannon pseudonym primarily for procedurals featuring LAPD Central Homicide Lieutenant Luis Mendoza (1960–86). Under her own name she wrote about Sergeant Ivor Maddox of LAPD's North Hollywood Station, and as Lesley Egan she wrote about suburban cop Vic Varallo. These novels are often considered severely flawed, partly due to the author's far-right political viewpoint (she was a member of the John Birch Society), but primarily because Miss Linington's books, notwithstanding the frequent comments she made about the depth of her research, were all seriously deficient in the single element most identified with the police procedural, technical accuracy.
