ITV
Vera
Brenda Blethyn’s gruff, whiskey-loving DCI Vera Stanhope prowls through Northumberland, solving cases with intuition and grit. It’s hard to resist her blunt honesty and the way the stunning landscapes become almost a character in their own right. Each episode feels like sinking into a moody, atmospheric novel—slow-burning, character-driven, and thoroughly immersive.
ITV
Shetland
Set against the rugged beauty of the Scottish Isles, Shetland follows DI Jimmy Perez as he untangles crimes within tightly knit communities. The remote setting adds a layer of tension—everyone knows everyone else’s business, and secrets are especially dangerous. It’s a compelling slow burn, with richly drawn storytelling that rewards patient viewers.
Sister Boniface Mysteries
This may be the quirkiest entry: a forensic-savvy nun tearing around on a moped, solving murders with a sharp mind and gentle humor. It’s cozy without being twee—plenty clever, a little wry, and refreshing in its whimsy. The sort of show you can turn to when you want to switch gears from more intense fare.
ITV
Passenger
Passenger is one of the newest shows on BritBox, and it’s already standing out. It’s set in a small Northern town and follows a detective trying to solve a disappearance that just doesn’t add up. What’s cool is that it’s a little bit surreal—playing with the usual mystery vibe in unexpected ways that keep you guessing. It’s moody, a bit offbeat, and honestly feels like the start of something really fresh and different.

New Tricks
This crime series follows a team of retired detectives brought back to crack unsolved cases. It plays on the generational clash between old-school cop instincts and modern investigative methods. The result is a show that blends clever plotting with surprising warmth and camaraderie.
ITV
Grace
Though rooted in darkness, Grace brings moments of levity through its flawed lead detective and the lively supporting cast. Set in Yorkshire, it walks a line between grit and nostalgia, with just enough emotional depth to balance its procedural roots.
ITV
The Tower
Based on Kate London’s novels, The Tower delivers tightly wound suspense in compact three-to-four episode seasons. Gemma Whelan stars as a determined investigator unraveling high-stakes murder cases while navigating the political pressure of a male-dominated police force. The show emphasizes the issues that arise when dealing with systemic flaws in law enforcement, adding emotional weight to its already gripping plots. It’s tense, thoughtful, and layered with realism.
