Nothing is as it seems behind the well-trimmed hedges of the picturesque cottages in the idyllic English county of Midsomer. Beneath the tranquil surface of sleepy village life exist dark secrets, scandals and downright evil. John Nettles stars as the humorous, thoughtful and methodical Detective Chief Inspector Barnaby. Sam Nealms, the postman, arrives at a cottage on Linton Pargeter's estate. There is no sign of the inhabitants Stan and Nesta Goodfellow. Molly and Colin Thomas' neighbouring cottage is the same. When Barnaby and Jones investigate they soon learn the history of haunted Monks Barton.
