Grace
8pm, ITV
The murky and intense adaptation of Peter James’s crime novels, set against the gusty Brighton coastline, returns for a second season. John Simm is back as DS Roy Grace, who believes the body of a former teacher and the finding of human remains are linked – the work of a sadistic serial killer who leaves a bizarre calling card at the scene of each crime. Down the road in Hove, a man finds a pen drive on the train that ends up getting him involved in the investigation and worrying for the lives of his wife and child. Hollie Richardson
Our Changing Planet
7pm, BBC One
An ambitious project with six threatened, changing habitats around the world tracked across seven years. We begin with Steve Backshall visiting the dazzlingly beautiful and minutely ecologically balanced coral reefs of the Maldives. A decent balance of righteous eco-polemic and nature celebration. Phil Harrison
Gentleman Jack
9pm, BBC One

First up is a business opportunity: the railway has arrived in town and Anne is curious. Then there’s the matter of an increasingly forlorn Mariana, who wants to talk. Henry Wong

SAS: Who Dares Wins
9pm, Channel 4
We’re halfway through the SAS selection process, and the remaining recruits are facing their most brutal challenges yet: a seven-metre backwards dive; hand-to-hand combat in a game of murderball, to test their aggression and strength; and an ambush while out driving. No surprise that four recruits will hand in their armbands before the credits roll. Ali Catterall
