Death Valley is currently streaming in Australia on BritBox, and in the US on Britbox Apple TV Channel , and its 6/10 TMDB rating reflects what viewers who've already found it know. 2 seasons that reward every hour invested.

The procedural format gives Death Valley its backbone, but it's the characters you come back for. Thrown together by the murder of John's neighbour, John and Janie are an odd, yet hilarious duo with opposing instincts. Every week, they get to the bottom of gripping murders, with various stunning Welsh locations providing a backdrop to their investigations. Timothy Spall and Gwyneth Keyworth lead a cast that brings real weight to the material. The series ran for 2 seasons (2025–2026), building a story that gave its audience time to invest properly.

If you're the type who can't walk away from a good mystery, Death Valley will keep you watching far longer than you planned.
