8 Bingeable British Detective Dramas With At Least 50 Episodes

While the British have produced hundreds of gripping, cozy, and thrilling detective dramas over the years, few boast more than 50 episodes. In fact, many have fewer than that; though some shows have six, eight, or 10-episode seasons, plenty have only two, three, or a maximum of four. Even shows with 10 or more seasons don't have that many episodes. It usually depends on the format, the source material, and the narrative structure.
Shorter seasons on British TV (no matter the genre) existed long before streaming popularized them in the US and globally. It's such a well-known phenomenon that even a sitcom like The Good Place made an excellent joke about it. Classic British detective dramas like Inspector Morse feature one story per feature-length episode; though the show ran for eight seasons, there are only 33 cases in total. Idris Elba's Luther earned global renown with just 20 episodes in five seasons. Even A Touch of Frost, which ran for 14 seasons, only boasts 42 episodes.
Still, a few excellent British detective dramas managed to (or are still managing to) keep audiences invested, murder mystery after murder mystery, episode after episode. From sunny, tropical investigations to sinister cold cases, these detective shows will keep viewers busy for a good long while.
8 Vera
56 Episodes | 14 Seasons
It was a genuine shame when ITV's Vera ended after 14 seasons last year, but thankfully, it produced 56 episodes to watch (or rewatch). Based on books by celebrated crime author Ann Cleeves, Vera is one of the most atmospheric shows on this list, set in the stunning Northern English landscape. Each story is a tragedy told with incredible empathy, led by one of the most interesting detectives the genre has ever seen.
Brenda Blethyn's DCI Vera Stanhope is a steadfast, quietly clever leader, calling everyone "love" and "pet" while unraveling her suspects' lies and suspicions. With her vintage blue Land Rover and trusty raincoat, DCI Stanhope is an undeniable genre icon. All episodes are now streaming on BritBox.
7 Shetland
56 Episodes | 10 Seasons
There's just something about Anne Cleeves' writing. The BBC's Shetland is also based on the author's work and is set in the remote Shetland Isles. Each six-episode season (except the first two-episode season) covers a new case, each as intricate and emotionally devastating as the last. All seasons are streaming on BritBox.
Shetland's eerie atmosphere and excellent character writing have allowed the show to survive a character transition after seven seasons, when long-time lead Douglas Henshall, who played DI Perez, opted to leave. Ashley Jensen took his place as DI Calder. The new dynamic between Calder and OG sergeant Tosh (Alison O'Donnell) gave the series a renewed energy, with the duo returning for the upcoming 11th season (bringing Shetland's total episode count up to 62).
6 Agatha Christie's Poirot
70 Episodes | 13 Seasons
Of course, this list includes an Agatha Christie series. She isn't called the Queen of Crime for nothing. ITV's Poirot is the ultimate Hercule Poirot adaptation, with Sir David Suchet portraying the mustachioed Belgian detective with incredible charm, flair, and wit. No one will ever come close, though many have tried. The show is available in full on BritBox and Acorn TV, while seasons 1–11 are available on Hulu and PBS.
Poirot is arguably one of the most iconic British detective dramas of all time. Across 13 seasons and 70 episodes broadcast between 1989 and 2013, the show adapted every case Agatha Christie ever crafted for Hercule Poirot. The show bravely switched formats halfway through; earlier seasons featured 50-minute episodes based on Christie's short stories, while the later seasons produced feature-length episodes based on the author's 33 Poirot-centric novels.
5 Waking the Dead
92 Episodes | 9 Seasons
Waking the Dead is one of the more intense shows on this list. Following an elite Cold Case squad using modern technology and psychological profiling to crack previously unsolvable cases, the show includes dozens of genuinely harrowing, thrilling stories. Each case unfolds over two episodes, led by the easily frustrated Detective Superintendent Boyd (Trevor Eve) and his rotating team. Only two other members stuck with him for the show's entire run: Sue Johnston's Dr. Grace Foley and Wil Johnson's DI Spencer Jordan.
It was long one of the BBC's most celebrated shows, winning an International Emmy Award for Best Drama Series in 2004. It was a leading force in the "unsolved cases" crime sub-genre. Other British cold case shows have followed in its footsteps, including ITV's excellent Unforgotten, which will return for season 7 soon, and the next show on this list: New Tricks. Waking the Dead is available to watch on BritBox.
4 New Tricks
107 Episodes | 12 Seasons
We've hit the hundred-episode mark! As it turns out, audiences really love a cold-case mystery series, though this one comes with a twist. Instead of a crack team of highly specialized officers using the best modern technology has to offer, the New Tricks squad is made up of retired police officers and their still-in-service high-ranking female leader. The retired coppers are bored, looking for a new challenge, and prefer using old-school methods to solve cases, while their fearless SOs, DSU Pullman (Amanda Redman) and later DCI Miller (Tamzin Outhwaite), try to steer them in the right direction.
Of all the shows on this list, New Tricks is probably the most like a standard procedural, with each hour-long episode introducing a new case for the gang to solve. It's a fun bunch of characters, and it's great to see them learn to work together despite their different professional backgrounds. The show ended on the BBC in 2015, but its legacy lives on. New Tricks is available on Hulu and BritBox.
3 Death in Paradise
125 Episodes | 15 Seasons
Death in Paradise is one of the BBC's most successful detective franchises, producing 120 regular-season episodes plus five additional Christmas specials between 2021 and 2025. It's also one of the few shows to have spawned an entire shared mystery universe. The so-called "Paraverse" consists of Death in Paradise and two additional spinoffs (so far): Beyond Paradise (4 seasons, 24 episodes) and Return to Paradise (2 seasons, 12 episodes). All three shows are available on BritBox, have been renewed, and are expected to return later this year and in early 2027.
Death in Paradise has clearly cracked the winning formula, combining sun-drenched tropical settings, interesting, Christie-like mysteries, compelling characters, and memorable, rotating lead detectives to create a show that could theoretically last forever. As long as a new Detective Inspector is willing to relocate to Saint Marie every so often, we'll have Death in Paradise.
2 Midsomer Murders
144 Episodes | 25 Seasons
Anyone on the hunt for a good cozy crime drama should look no further than ITV's Midsomer Murders. Alongside Poirot, it's one of the most iconic British detective shows ever broadcast (there's even a stage play version of the pilot episode touring across the UK). There are currently 144 episodes, with more still on the way. Based on the books by Caroline Graham, Midsomer Murders follows DCI Barnaby #1 and later, DCI Barnaby #2 — yes, they're related — as they solve the most heinous murders in the fictional county of Midsomer.
At least 3 or 4 villagers die per feature-length episode; after 25 seasons, it's a wonder there's anyone left to kill in Midsomer at all. While all of that might sound brutal, and the murders are usually creatively vicious, the show is oddly relaxing and comforting. It's like sinking into your couch with a cup of tea in hand, and luckily, all 25 seasons are available to stream on Acorn TV.
1 Silent Witness
268 Episodes | 29 Seasons
The BBC's longest-running crime drama focuses more on forensic investigation than police work, though the scientists of the prestigious Lyell Center are essentially detectives in their own right. In fact, throughout Silent Witness' impressive 268-episode run, Dr. Nikki Alexander (Emilia Fox) and Co. often take matters into their own hands, which leads to results but also genuinely dangerous situations. All seasons are available now on BritBox, and the show will return for a landmark 30th season next year.
Silent Witness offers the perfect balance of meticulous scientific detail, compelling characterization, and heart-wrenching mysteries. For most of the show, the cases are split into two parts. Each story features a new or returning detective, and the Lyell team can be called in to investigate brand-new bodies that have become unidentifiable, as well as decades-old cold cases. Some episodes are more philosophical while others are straight-up thrillers. Silent Witness has been on the air since 1998 for a reason; you'll certainly never be bored when watching this unusual British detective drama.
