Detective drama set in a 1950s Cambridgeshire village, where local vicar Sidney Chambers (James Norton) develops a sideline in sleuthing - with the initially reluctant help of grumpy DI Geordie Keating (Robson Green). The cleric's first case finds him presiding over the funeral of a solicitor, who is believed to have taken his own life. However, the dead man's mistress has a different theory - and feeling unable to go to the police, she asks Sidney to examine it for her. He uncovers evidence that the suicide was staged, but while he's busy delving into the personal life of the victim, will the vicar miss his own big chance with Amanda Kendall (Morven Christie), the woman he secretly loves?
