About the title
What to do with yourself in retirement? Joyce, Elizabeth, Ron, and Ibrahim, residents of a retirement home, decide to start a detective club. Every Thursday they get together to rack their brains over one of the police's unsolved cases. It's all just a game and a way to keep their minds sharp — until one day the friends run into a real crime. Now they have a chance to prove they've still got what it takes and help the police. Will the amateur detectives manage to find the culprit? An adaptation of Richard Osman's bestseller of the same name.
