The Bletchley Circle is an enormously popular British miniseries about four women who worked as codebreakers in World War II in Bletchley Park outside London and who are able to put their skills and training to good use after the war to track down criminals outside police channels. In the first season, which premiered in the U.S. in 2013, the four women went after a serial killer after picking up what the police had missed – the hidden pattern of the killings. Like many popular films, its interest is sociological as much as dramatic, for such films are popular precisely because they strike a responsive chord in the viewing audience.
