Deadwater Fell (C4, 9pm)

DAVID Tennant is going back to his Broadchurch roots with another drama about a small community that is rocked by a terrible crime, but this time he’s one of the suspects rather than a cop. He plays Tom Kendrick, a popular local GP in the sleepy Scottish village of Kirkdarroch, who lives with his teacher wife Kate (Anna Madeley) and their three daughters. Their life seems perfect, until one night there’s a fire at their house. Tom gets out, but his wife and children don’t – and the tragedy takes a sinister twist when it emerges that it wasn’t the blaze that killed them. Kate’s best friend Jess (Cush Jumbo) is determined to find out what really happened.

Grantchester (STV, 9pm)

JAMES Norton may have moved on, but it seems there’s still plenty of life in Grantchester. The fifth series picks up 12 months after its predecessor; it’s 1957 and Prime Minister Harold Macmillan is insisting that the British people have never had it so good. However, Geordie Keating knows that trouble is never far away. The first episode sees Geordie and parish priest Will Davenport join forces to solve the mystery of the death of a student from a prestigious college.

Chris Packham: Forever Punk (BBC4, 9.30pm)

TV presenter Chris Packham is a massive fan of punk rock. In October, he managed to slip 14 song titles into an episode of Autumnwatch as a tribute to Eddie and the Hot Rods frontman Barrie Masters, who had recently passed away. Here, Chris looks back on his love of punk as a teenager and explains how it galvanised him to become an environmental campaigner. However, he also wonders if he has turned into the kind of establishment figure his younger self would have hated.
