Beyond Paradise series 4: Episode 6, the season finale, welcomes Gavin & Stacey legend to the cast
It's an emotional episode, that's for sure!
Beyond Paradise series 4 comes to a bittersweet ending this week, as one character leaves Shipton Abbott, and another makes a huge decision about their future – and the guest cast of episode 6 is pretty good, too.
After Humphrey’s huge sacrifice last week, it’s his last day as detective inspector this Friday (May 01, 2026). And, of course, there’s one last case for him so solve. As the town’s annual pirate festival kicks off, there is tragedy when Geraldine Desai’s nautical exhibition goes up in smoke… And the ancient treasure map of pirate Elias Cutler goes missing amid the chaos.
On the trail of the missing map, Humphrey soon has suspicions when he discovers that Geraldine has been selling her memorabilia to pay for her husband’s care and recently had the map revalued.
Here’s who plays who in Beyond Paradise series 4 episode 6, the final episode of 2026.

Swansea-born actress Melanie Walters, 64, plays Geraldine Desai in the season finale of Beyond Paradise. Of course, she’s best known for playing Stacey’s mum Gwen West in the BBC sitcom Gavin & Stacey in all three series and subsequent specials.
She’s also famous for portraying Gran in the children’s TV series Biff & Chip, based on the educational books, Nain Griffiths in The Snow Spider, Kitty in Pitching In, and Genevieve in The Collection.
