Carys Nicholson is a character appearing in the episode The Miniature Murders of the ITV crime drama Midsomer Murders.
She first shot Alexander Beauvoisin in the chest with a wooden bullet fired from a Swedish semiautomatic gun through a miniature house, to prevent him from discovering that Maxine Dobson was hiding a body in her cellar. She then slit Jemima Starling's throat with a small penknife because she saw Carys and Maxine move the body somewhere else.
