Things are looking merry and bright this Christmas in Shipton Abbott – but the Devon town is set to be rocked with a new mystery in Beyond Paradise’s Christmas Special.

Naturally, there’s a lot of famous faces on hand to help.

Joining Humphrey and Martha for the most wonderful time of the year includes Adrian Edmondson (Alien: Earth), James Lance (Ted Lasso) and Jonny Weldon (One Day).

The official synopsis reads: “When Esther discovers a man on the steps of the Shipton Abbott police station with no memory, holding a photo of Humphrey, the team gets to work to uncover who the mysterious man is while balancing a flurry of festive cases.

“At the same time, with the help of Anne, Zoe and a special guest, Martha races to pull off her secret plan while Kelby tries to help a mystery man trapped inside his snowman costume.

“But with an influx of unexpected visitors, a slew of holiday crimes to crack, and a heartwarming reunion on the line, can the team juggle it all and still be ready for a life-changing reveal?”

Beyond Paradise is available to watch on BBC iPlayer.
