Midsomer Murders: Barnaby and Troy go out to the village of Midsomer Malham to investigate death threats against Melissa Townsend, the beautiful daughter of the big house. They find that some Midsomer Malham villagers blame Melissa for causing the death of a local poacher by failing to get the leaking roof of his cottage mended. Then barbiturates are stolen from Raif and Georgina Canning's veterinary surgery and the district nurse is found in her crashed car in a confused state. Barnaby and Troy dash to the Manor, fearing the drugs theft may be connected to the death threats - but they find Melissa is already lying dead by the swimming pool with a syringe in her stomach. Now they have a murderer to find.
