Casebook interpretation
Welcome to Causton
The county town and practical centre of Midsomer, where police work, family life and civic business connect the otherwise scattered villages.
Causton is busier and less storybook-pretty than the villages, but it gives the series continuity and a sense of a functioning county beyond each week's mystery.
Why fans remember it: The police station, the Barnabys' everyday world and the civic institutions that hold the county together.
Editorial interpretation The village is fictional; real places linked to its stories are listed below when known.
