Joseph Millson fans have a special treat this evening. His guest episode of Granchester, as Mr Pope, airs tonight at 9pm on ITV. The Grantchester series 4 DVD will be released on 4th March 2019.

Reeling from his family tragedy, Will seeks distraction in Geordie's world where a curious case unfolds concerning the murder of a Teddy Boy at a dance hall. The dead boy's pockets reveal a library card from Esme's school, and even more disturbing - a picture of Esme herself. Geordie makes a beeline for the school and grills his frightened daughter. She pleads ignorance, but Will knows something is up when he spots her hiding a love letter. Away from her life at the vicarage, Mrs Chapman feels lost, while Cathy is left shaken by another encounter at work. Robson Green and Tom Brittney star.
