Brutal stabbing of Karen Carter, 65, in France has been followed by talk of affairs and speculation over the culprit

The quiet village of Trémolat nestled in the Dordogne valley is best known for its “cingle”, where the sinuous river forms an Instagrammable loop.

Home to about 700 people, along with restaurants, a cafe, boulangerie and wine bar, it is a picture-perfect French idyll and a popular place for a getaway or even retirement.

Karen Carter, a 65-year-old British-South African national, knew the appeal of Trémolat well: she ran two gites in the village, a beautifully renovated 250-year-old farmhouse and neighbouring 18th-century stone barn collectively called Les Chouettes.

Carter, who bought the gites with her 65-year-old husband, Alan Carter, 15 years ago, divided her time between the Dordogne and the home the couple shared in the city of East London, South Africa.
