Accused of murdering our son – The Steven Clark Story on tonight's TV

On December 28, 1992, 23-year-old Steven Clark disappeared; he was last seen close to his home in Marske, near Redcar. Twenty-eight years later his now elderly parents Doris and Charles were arrested on suspicion of his murder, despite the fact his body has never been found. They were subsequently released, and here, they get to tell their side of the story. Ex-detective Mark Williams-Thomas – who will be familiar to those who saw ITV’s acclaimed documentary The Other Side of Jimmy Savile – reinvestigates the case, spending 17 weeks with the Clarks as they endure a terrifying ordeal. Charles and Doris also discuss their son, who was left disabled by a car accident when he was a toddler, and reveal the devastation they felt at being accused of his murder.

Escape to the Farm with Kate Humble

Escape to the Farm with Kate Humble (C5, 8pm)

TO help farmer Tim celebrate his birthday, Kate joins him, his wife Sarah and their dog Taff on a walk in the town of Blaina, where he grew up. It’s a real trip down memory lane, during which he remembers learning his craft. Tim also plans a spending spree that should liven things up on Kate’s farm before doing something few of us would fancy tackling – collecting sheep droppings for a vet inspection. Thankfully, Kate is carrying out a far more palatable task – she’s preparing a hearty stew and a traditional local cake.

Dragons' Den: trying out the product Sara Davies

Dragons’ Den (BBC One, 8pm)

Evan Davis welcomes more budding entrepreneurs into the Den –but will tycoons Peter Jones, Deborah Meaden, Touker Suleyman, Tej Lalvani and Sara Davies be impressed enough to offer financial backing to the products and services? A DJ and dancer pitches a socially-distanced nightclub business and an Irish inventor presents a muscle-massaging device. Plus, a pair of optical consultants have their sights set on investment with their ready-readers business, and a tech enthusiast demonstrates his method of monetising personal online data.

Taskmaster

Taskmaster (C4, 9pm)

It isn’t easy to get into Greg Davies’ good books, as Charlotte Ritchie, Jamali Maddix, Lee Mack, Mike Wozniak and Sarah Kendall are discovering. Nevertheless they’re continuing their efforts to do so, with varying degrees of success. While Jamali sets to work redecorating the caravan, a kiwi fruit leaves Sarah aghast. But it’s Mike’s shocking revelation that stuns everyone so much, Davies will be lucky if he can persuade them to do anything afterwards. Thankfully, Alex Horne is on hand to keep matters ticking over.

Don Rodolfo (Ciarán Dowd)

Don Rodolfo (BBC2, 10pm)

In 2018, Irish comedian, actor and writer Ciaran Dowd won the 2018 Edinburgh Comedy Award for Best Newcomer for his debut solo show, entitled Don Rodolfo. He describes the titular character as “the grotesque love child of Don Juan and Don Quixote”. This short comedy (it’s an all-too-brief 10 minutes long) is a spoof swashbuckler in which Rodolfo discusses his conquests, adventures and even thoughts, some of which he really should keep quiet about. If the show proves popular, a series may head our way in the future.

Frank of Ireland

Frank of Ireland (C4, 10pm)

Even if you were desperately ill, would you agree to let Frank and his hapless best friend Doofus take care of you? After watching their antics in last week’s opening episode of the Gleeson brothers’ sitcom, the answer would surely be no. But it seems that poor Mary has no choice – she’s bed-ridden and requires the boys to help her with a number of chores. Initially they throw themselves into their tasks with enthusiasm, although giving her some sleeping pills so that they can complete them without her interference doesn’t seem to be a great idea. Then, to make matters worse, they return from the laundrette to find her missing – could Mary simply have just gone out on a date, or is something more sinister going on?
