Grantchester ITV, 9pm
New series. 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 out when he presides 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. With Tessa Peake-Jones, Kacey Ainsworth and Rachel Shelley.
