Here's our guide to the best UK TV to watch this week.
Saturday 29 July, 9.00pm: Clean Sweep (episodes 1 and 2) | BBC Four
This new Irish thriller is centred on mum-of-three Shelly Mohan (Charlene McKenna) whose life is the regular grind of school runs and supermarket trips. But then a face from her past resurfaces and a crime is committed – which her police detective husband Jason (Barry Ward) is assigned with investigating.
Suddenly, Shelly has a whole load of secrets she needs to keep hidden from her nearest and dearest. But Jason too is arousing suspicion with claims of infidelity threatening his and Shelly’s marriage. Expect plenty of brooding looks and frantic cover-ups over the course of six episodes.
Monday 31 July, 9.00pm: Wolf (episodes 1 and 2) | BBC One
DI Jack Caffery (Ukweli Roach) is the latest in a long line of TV detectives plagued by demons. In his case, those nightmares have their root in a traumatic event from the 1990s, when Jack’s 10-year-old brother was murdered. Hence the police officer’s obsession with the neighbour he believes to be responsible for the crime.
This six-parter has been adapted by Hartswood Films (they of Sherlock and Inside Man fame) from the bestselling books by Mo Hayder. And if you’re after an idea on tone, we’re very much at the darker end of the crime drama colour spectrum. Continues Tuesday.
Tuesday 1 August, 9.00pm: Wonders of the Moon with Dara O Briain (episodes 1 and 2) | Channel 5
The Mock the Week host indulges his love of astronomy in this new two-parter airing over consecutive nights which looks at the way the Moon has shaped just about everything around us.
Dara’s journey begins with an exploration of how the Moon governs time and still influences such things as farming and the pull of the earth’s tides. Episode two then expands the remit with a study of the dark side of the Moon before Dara discovers the likelihood of a base being 3D printed on our planet’s only natural satellite. Could the sci-fi storytelling of Space: 1999 become a reality? Concludes Wednesday.
Wednesday 2 August, 9.00pm: Celebrity MasterChef | BBC One
The aim for the 20 famous faces competing is, of course, to succeed last year’s winner Lisa Snowdon as the Celebrity MasterChef Champion. But might some of those in contention find the heat of the kitchen too much to bear?
The latest line-up of culinary hopefuls appear to have been picked to appeal across the age ranges, with the likes of Sam Fox and Terry Christian there for anyone who came of age in the 80s and 90s, while Dani Dyer and Apl.de.Ap ought to find favour with a younger crowd. Also in the mix are many who’ve tried their luck on other celeb-based shows, such as Strictly alumni Richie Anderson and Max George. All will have to appeal to the tastebuds of presenters John Torode and Gregg Wallace.
Thursday 3 August: Heartstopper (season 2) | Netflix
Series two of the life-affirming drama takes Charlie (Joe Locke), Nick (Kit Connor) and their peers off to Paris for a school trip. But there’s no break from life’s problems, with Charlie’s relationship with food arousing concern, while Nick tries to reach out to his French (and largely absent) father.
