This week Susan (and Helen Mirren the campervan) heads to the beautiful Causeway Coast of Northern Ireland. She starts out at Glenarm Castle and learns that it used to have a much larger estate — until a previous Earl lost over 100,000 acres through gambling. Whoops!

There’s also a chance for golfing enthusiast Susan to tick off a bucket-list item by playing a hole at the world famous Royal Portrush Golf Club — and after an impressive opening drive, she vows to get a commemorative tattoo if she pulls off a par — so will Susan be returning home with some new ink?

The Graham Norton Show, 10.40 pm, BBC1

Graham’s sofa is so hot tonight, it may self-combust. Emma Corrin shares secrets of her Netflix version of Lady Chatterley’s Lover, Paul Mescal talks family drama Aftersun and Winston Duke and Michaela Coel are on the Black Panther: Wakanda Forever promotion trail. Plus, the unrivalled Richard Ayoade has written his first children’s book.

DNA Journey, 9 pm, ITV

Larry Lamb and Alison Steadman — (Image credit: ITV)

Alison Steadman and Larry Lamb are embarking on a journey into their DNA, and the Gavin & Stacey favourites begin by meeting at Barry Island, delighting a few locals who spot them together on the seafront. Then it’s off to an East End pub in the back of a cab, where they enjoy a rousing chorus or two of Knocked ’em in the Old Kent Road.

Former EastEnder Larry discovers a family tale worthy of a ‘doof doof’, but on their next part of the journey, which eventually takes them to the Isle of Man, Alison shares some news about her beloved father that has left her feeling shaken and emotional.

Best box set to watch on TV tonight

The Devil's Hour, Prime Video

Social worker Lucy Chambers springs awake at 3.33 am every morning – a time known as the ‘devil’s hour’. In this nail-biting six-part thriller with a supernatural edge, Jessica Raine plays Lucy, a haunted and overburdened mother who has recently separated from her husband. Lucy is also struggling with the demands of caring for her schizophrenic mother and her troubled eight-year-old, Isaac, who she takes to see a child psychiatrist (Meera Syal). Meanwhile, a murder is being investigated by DI Ravi Dhillon (Nikesh Patel) and DS Holness (Alex Ferns), one with bizarre links to Lucy’s visions and connected to a murder-obsessed stranger, Gideon, played by Peter Capaldi.

Best film on TV tonight

Booksmart, 9.30 pm, BBC3

Beanie Feldstein and Kaitlyn Dever in Booksmart — (Image credit: BBC)

About to leave high school for Ivy league college, swotty best friends Beanie Feldstein and Kaitlyn Dever realise the people who were having a raucous time while they were busy studying are also going to the best colleges. The two girls had forgone fun for no apparent reason. So, in one night, they make up for lost time in the funniest, sharpest, most tender comedy for some time.

The acting is perfect and the script positively crackles in actor Olivia Wilde’s debut directing gig (her second, Don’t Worry Darling, was recently released), eschewing high-school clichés to reveal something far more truthful.
