The senior citizens of Copper’s Chase are hoping for a year without murders — or at any rate, Joyce’s daughter is. Unfortunately, the antique dealer Kuldesh Sharma is shot in the head and he happens to be a friend of Elizabeth’s husband Stephen which makes the murder personal. The Thursday Murder Club, against the wishes of the National Crime Agency, proceeds to step into the investigation, discovering a world of drug dealers and a missing box of heroin — this despite the fact that their own favourite police officers, Donna and Chris, have been sidelined from the investigation.
