Midsomer is an English county which consists of numerous chocolate box villages. The county town is Causton and it also happens to be where the now retired Detective Chief Inspector Tom Barnaby (John Nettles) and his wife Joyce (Jane Wymark) live. The Criminal Investigation Department (CID) is located there and where Tom's cousin, Detective Chief Inspector John Barnaby works along with Detective Sergeant Ben Jones (Jason Hughes). The emblem for Midsomer Constabulary is a badger, as shown in the series. The first village to feature in the pilot episode was Badger's Drift, which was titled The Killings at Badger's Drift, where the first victim was Emily Simpson.
