22 Must-Watch TV Shows on BritBox Right Now (October 2025): ‘Karen Pirie’ and more

Are you ready for your next mystery show obsession? Because once you start watching Death Valley, you probably can’t stop until the last episode is over.

John Chapel (Harry Potter star Timothy Spall) is restless and bored. A beloved actor best known for playing a popular detective on TV, his retirement has so far proven to be a bit dull and uninspiring. But when John’s neighbor turns up dead, he’s inspired to solve the case himself. He’s helped by Detective Janie Mallowan (Gwyneth Keyworth), who actually has experience solving crimes, and together, the duo solves numerous crimes in and around their sleepy Welsh village.

Death Valley works as both a mystery and a comedy, and that’s largely due to Spall, who imbues Chapel with enough wit and charm to make him a hero you want to root for — and sometimes strangle. He’s a quintessential British mystery lead — frustrating, eccentric and irresistible. That also describes Death Valley, a show you hope will have many more seasons in its future.
