S11:E03 - Left for Dead

Barnaby and Jones are in Dunstan to investigate the deaths of a reclusive couple. As they try to establish whether Ron and Libby Wilson were murdered or died of natural causes, their attention is drawn to a dispute raging between a local builder and road protesters nearby. When another death occurs, the detectives learn that there are plenty of dark secrets and fierce hostilities in this apparently idyllic village. Will Jack Purdy's quick temper lead to violence? How far would the protesters go to prevent the bypass being built? And do current events somehow relate to the death of Michael Wilson many years earlier?
