Shetland
9pm, BBC One
The latest case for Jimmy Perez (Douglas Henshall) reaches a conclusion that’s close to home, as the detective faces the possibility that his stepdaughter Cassie’s biological father Duncan (Mark Bonnar) was involved in the murders of Lizzie Kilmuir and Sally McColl. In such fraught circumstances, pursed lips and other serious faces inevitably follow, especially as a hurt Duncan can’t quite believe anyone could think him capable. Meantime, troubled Malone goes out and about with a shotgun. A tense and compelling cop drama. Jonathan Wright
The World’s Ugliest Pets
8pm, ITV
A pointed corrective to the mollycoddled madness of Crufts. En route to the World’s Ugliest Dog contest in California, avowed animal lover Caroline Quentin meets some of the UK’s sorriest-looking mutts, scraggiest moggies and even a giant slimy snail to try to prove that true beauty is in the eye of the pet holder. Graeme Virtue
100 Years Younger in 21 Days
9pm, ITV
The voyeuristic but entertaining MOT for addled celebs concludes. Shaun Ryder has been the star – sadly it turns out that a month on the green juice can’t undo a lifetime of chemical adventurousness. June Brown, meanwhile, has been a joyous poster-girl for the power of positive thinking and heavy smoking. Phil Harrison
Who Do You Think You Are? USA
9pm, W
“My 18 times great-grandfather is holding the king’s father prisoner? This is getting juicy!” Courteney Cox delves into her English aristo roots (“If this was 700 years ago you’d be slightly less than a queen,” she’s informed), uncovering a royal scandal in the latest Stateside episode of the popular genealogy series. Ali Catterall
Frontiersman
9pm, History
The debut of an unwatchably idiotic series celebrating Daniel Boone, Davy Crockett et al – the wispy bearded adventurers who lit out for the territory in revolutionary America. Fascinating stories but ineptly told, via the medium of amateur-hour recreations soundtracked by action-movie din. Andrew Mueller
Mum
10pm, BBC Two
Lesley Manville continues to charm gently as the mother in question, facing an awkward reunion with Michael after a summer apart. As the rest of the family buzz around being gloriously annoying (particularly the tact-free wonder that is Kelly, played by Lisa McGrillis) you can’t help but wish that they could get some time alone. Hannah Verdier
TV film
Requiem for a Dream, 1.45am, Film4
This nightmarish descent into a drug-saturated hell is a queasy swirl of gruesome images and frantic, split-screen mayhem. Ellen Burstyn is the widow hooked on TV game shows and diet pills, her son (Jared Leto) is a would-be dealer, and Jennifer Connelly his addicted girlfriend in a raw drama. Paul Howlett
