About “The Bletchley Circle”:
The Bletchley Circle is a television mystery drama series, set in 1952–53, about four women who had worked as codebreakers at Bletchley Park, the principal centre of British code-breaking during the Second World War. Dissatisfied with post-war official failure to investigate complex crimes properly, the women join together to investigate for themselves and to bring their findings to the relevant authorities.
