Causton
A brewery in the ruins of a supposedly cursed abbey produces a body in a vat and a victim with two identities.
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 Where the programme has not established a resident, building or piece of geography, the Casebook leaves it unstated rather than turning inference into canon.
