If you're in the mood for a good mystery that doesn’t feel too flashy or over-the-top, BritBox has a seriously strong lineup of British detective series that quietly get the job done. These shows lean into character development, sharp writing, and atmosphere rather than non-stop action, and that’s what makes them so binge-worthy. There’s a calmness to them, even when the stories get dark.
They’re smart, steady, and surprisingly comforting, especially if you’re the type to throw on a murder mystery to wind down. So, here are some of the best BritBox detective series that are actually worth watching from start to finish.

ITV
Vera
Vera is one of those shows that doesn’t make a lot of noise but hooks you anyway. DCI Vera Stanhope is sharp, blunt, and totally unbothered, with a wardrobe that never changes and a dry wit that sneaks up on you. The episodes are long—basically mini-movies—but never drag. There’s something about the gloomy Northumberland backdrop and Vera’s no-nonsense vibe that just works.
ITV
Inspector Morse
This one’s a classic that still holds up. Set in Oxford, Inspector Morse follows a detective who’s a little prickly and a lot smarter than he lets on. He’s into opera, drinks too much, and loves a good puzzle—both on paper and at a crime scene. The mysteries are detailed, thoughtful, and always a little more layered than you’d expect.
PBS
Inspector Lewis
A follow-up to Morse, this series focuses on his former partner, now a lead investigator in his own right. Inspector Lewis keeps the Oxford setting but updates the tone just enough. Lewis is a bit more open emotionally, and his chemistry with his partner Hathaway brings in a new dynamic that adds depth without straying from the original vibe.
ITV
Shetland
Shetland makes the most of its isolated island location. Despite the weight of the cases, the narrative never seems hurried. Even when things feel hopeless, Jimmy Perez remains composed, kind, and easy to support. Although it moves more slowly, the reward is worthwhile. Additionally, the landscape is enough to make you want to binge-watch.
Acorn TV
Line of Duty
If you're looking for something more high-stakes, Line of Duty ramps things up. It’s tense and twisty, following an anti-corruption unit investigating dirty cops. The interrogation scenes are wild—just long, quiet back-and-forths that somehow feel more intense than any car chase. It’s addictive, but still grounded in solid character work. Definitely a must-watch.
PBS
Grantchester
A little lighter fare is Grantchester, which follows a young priest and a detective as they investigate crimes in a tiny English community. The emotional arcs seem genuine, and it's warm without being corny. The exhibition is balanced by charm, but the cases also carry enough weight to keep you interested.
