10 Best British Detective Shows Based on Books
Finding a British detective drama that balances a satisfying mystery with characters worth spending time with can be harder than the actual case. This countdown brings together ten screen detectives whose stories began on the page, from sharp modern reinventions to patient, atmospheric adaptations. The ranking weighs more than name recognition: it considers how clearly each series translates its source, how compelling its lead investigator is, how well its cases build, and whether the show offers a distinctive place to return to. Different entries suit different moods, from brisk modern cases to slow-burn character work and atmospheric landscapes. Each is judged as both an adaptation and a detective drama, so readers can choose a classic or a reinvention.
If you want a classic whodunit, a tense police procedural, or a character-led crime binge, you’ll find a different kind of pleasure in each pick. The order is deliberate: the lower entries are worthwhile adaptations, while the final few combine stronger storytelling with a more memorable lead and a fuller sense of place. We also flag where the books remain especially important to the experience, because these shows are adaptations rather than interchangeable television mysteries.
UK streaming services change their catalogues, so the viewing notes reflect current listings checked for this guide and should be rechecked before you settle in.
There are several good ways to begin this watchlist. If you want a quick sense of how a classic detective can be reimagined, start with Sherlock; if you would rather settle into a patient case and a long-standing partnership, Inspector Morse is waiting. Viewers who like a recurring investigator returning to a recognisable patch can try Vera or DCI Banks, while Shetland shows how isolation and local memory can deepen a police mystery. The period settings in Dalgliesh and Grantchester offer another kind of pleasure, with character and atmosphere doing as much work as the clues.
A book adaptation also carries a particular promise: a detective’s habits, blind spots and method were shaped in prose before they reached the screen. The strongest series here do not depend on you having read a novel first, and there are no ending spoilers in the countdown. Instead, each entry explains its starting case, its main relationship and the specific reason it sits at that point in the order. We have kept the difference between a show originating in a book series and a show that only borrows a character in mind, too. By the end, you can choose a mystery for its setting, pace or lead rather than picking a title only because it is famous.

10. Wycliffe
Cornwall is the starting point for this traditional police procedural, where Detective Superintendent Charles Wycliffe leads investigations with the steady help of DI Doug Kersey and DS Lucy Lane. Each case begins with a death or disappearance that unsettles a close-knit community, then opens onto family loyalties, local grudges and the secrets people have learned to keep. The crimes give the unit a clear puzzle to solve, but the series is equally interested in what the investigation reveals about ordinary lives in a coastal county. Viewers get a measured, case-by-case mystery rather than a single season-long conspiracy.
Jack Shepherd’s Wycliffe is a quietly persuasive centre: observant, calm and more interested in listening than grandstanding. The show’s Cornish settings give the investigations a distinct texture, and its procedural rhythm makes it easy to dip into an episode without losing the thread. That same steadiness can sometimes feel old-fashioned, especially beside faster contemporary thrillers, and the ensemble does not always receive the same depth as the lead. Still, the source novels by W. J. Burley give the series a strong detective tradition to draw from, and the adaptation understands that an interview, a contradiction and a slowly changing suspicion can be as satisfying as a chase.
Why it ranks here: Wycliffe earns a place in the countdown because it is a genuine book-based detective series with a coherent lead and a memorable setting, but it sits tenth because its familiar, unhurried formula is less distinctive than the character work and atmosphere of the shows above it. It is a good starting point for viewers who enjoy classic British crime drama, patient investigations and self-contained cases. Where to watch: UK availability is listed on ITVX, including free-with-ads episodes; Sky Go and ITVX Premium are also listed. Check the current JustWatch guide before watching.
9. Midsomer Murders
In Midsomer County, an apparently peaceful village can conceal a remarkably inventive murder. The series follows DCI Tom Barnaby and, later, DCI John Barnaby as they work with their sergeants to examine suspicious deaths in communities where family histories, village rivalries and eccentric traditions complicate every interview. A new case usually arrives with a local gathering or a seemingly ordinary dispute, then expands as the detectives discover how many people had reason to resent the victim. Its central pleasure is the contrast between picturesque English scenery and the darkly comic ingenuity of the crimes.
The show’s enormous run gives it an unusually broad catalogue of mysteries, and its format is friendly to casual viewers: each episode offers a contained puzzle, a parade of suspects and a reassuring return to the county. The books by Caroline Graham provide the original world, while the long television life has developed its own identity through recurring investigators and a lightly theatrical tone. The formula can be knowingly cosy, and viewers seeking gritty realism may find its violence and village eccentricity polished for entertainment. Yet that tonal confidence is exactly why Midsomer Murders remains an easy recommendation for a low-pressure crime night.
Why it ranks here: it beats Wycliffe on rewatchability and the sheer variety of its cases, but stays below the stronger character-led adaptations because the rotating cast and broad comic style make its emotional continuity less rich. Choose it when you want an English village whodunit with a bright surface, a clever puzzle and no need to remember a season-long plot. Where to watch: ITVX currently offers the series free with ads in the UK, with ITVX Premium and STV Player also listed. Availability can differ by season.
8. Grantchester
Set in a Cambridgeshire village in the 1950s, Grantchester begins with Sidney Chambers, a vicar whose pastoral work brings him close to the people who need help and whose curiosity keeps drawing him into police investigations. He forms an unlikely partnership with Detective Inspector Geordie Keating, a practical, sometimes weary officer who knows the limits of evidence and the cost of every case. Their different instincts become the engine of the show: Sidney listens for motives and moral contradictions, while Geordie follows procedure. Each murder disturbs the village’s social calm and tests the men’s ideas about justice, faith and loyalty.
The series adapts James Runcie’s The Grantchester Mysteries and gives its investigations a gentle character-drama frame. The pleasure is in the contrast between the vicarage and the police station, and in watching Sidney and Geordie learn to trust a colleague who sees the world differently. The period setting is handsome without becoming the whole point, while the mysteries are accessible enough for a relaxed weekend binge. At times the changing cast and recurring personal subplots make the long run uneven, but the central friendship gives it more emotional continuity than many village procedurals.
Why it ranks here: Grantchester places above Midsomer because its central relationship gives the cases a stronger emotional through-line, but it does not reach the upper tier because the episodic mysteries can be less surprising than the sharper adaptations ahead. It suits viewers who like cosy British crime with thoughtful questions, warm ensemble chemistry and a little romance around the edges. Where to watch: ITVX and STV Player carry the show in the UK; current listings also include ITVX Premium. Check the season page for exact availability.
7. Strike
Cormoran Strike is a war veteran and private detective trying to keep a tiny London agency afloat when a new client brings him a case that the police have struggled to resolve. Robin Ellacott, initially hired as a temporary assistant, proves more capable and more curious than either of them expects. Together they investigate murders and disappearances that lead into the lives of celebrities, families and strangers who have learned to hide behind a respectable public image. The cases are the immediate hook, but the evolving partnership between Strike and Robin gives the series its continuing dramatic question: can two guarded people build trust while working in a dangerous profession?
Based on J. K. Rowling’s crime novels written as Robert Galbraith, the television adaptation benefits from a clear literary architecture: each mystery has a culprit, a method and a social world that matters to the solution. Tom Burke and Holliday Grainger make the leads compelling without smoothing away their rough edges. Strike’s physical limitations and Robin’s growing investigative confidence affect how they approach a case, so the detective work is tied to character rather than just clue collection. Some instalments are dense, and viewers who prefer brisk, one-hour mysteries may find the plotting elaborate. For patient crime fans, however, the detail is a feature.
Why it ranks here: Strike moves above Grantchester because its mysteries are more intricate and its two-hander gives the adaptation a stronger long arc, though the pacing is less immediately cosy. It is especially good for viewers who enjoy book-to-screen detective adaptations, London settings and cases that reward attention. Where to watch: BBC iPlayer and Disney+ currently list Strike in the UK; digital purchase options are also available.
6. Dalgliesh
Adam Dalgliesh is a London detective who brings an unusual combination of analytical patience and emotional restraint to cases shaped by power, class and private grief. The series opens in the 1970s, where a murder at a church, a medical school or a country institution draws Dalgliesh into a circle of people whose public roles conceal older rivalries. He interviews witnesses, follows inconsistencies and gradually works out which tensions matter. The cases are adapted from P. D. James’s novels, while the recurring presence of Dalgliesh’s colleague DS Kate Miskin adds a second perspective to investigations that can otherwise feel deliberately solitary.
Bertie Carvel plays the detective as a thoughtful observer rather than a theatrical genius. He is not written to solve a puzzle by performing cleverness at the room; he notices what other people have stopped noticing. The period detail and restrained production design support that approach, allowing conversation and atmosphere to do much of the work. Dalgliesh’s grief is part of his character but not a shortcut to sentiment, and the show’s serious tone gives the novels room to breathe. That seriousness can also make the pacing feel stately, and the stories sometimes keep their social worlds at a distance.
Why it ranks here: Dalgliesh enters the top half because the adaptation captures the literary intelligence of its source and gives its lead a distinctive inner life. It ranks below the top five because it is less warm and less immediately involving than the strongest series here, especially if you prefer a substantial partner ensemble. Watch it for thoughtful, atmospheric mysteries and a detective who treats evidence with care. Where to watch: Acorn TV and its Amazon and Apple TV channels currently list the show in the UK; no free option is listed.
5. Shetland
On the remote Shetland Islands, detective Jimmy Perez investigates crimes that disturb a community where people are connected by geography, family and long memory. The series begins with a murder that draws Perez back into relationships he cannot treat as simple witness interviews; as cases widen, the landscape and the community’s history shape both the clues and the stakes. Douglas Henshall’s Perez is an experienced investigator, but he is also a father and neighbour whose work makes privacy difficult. His partnership with Tosh and the local team places each mystery inside a network of loyalties that can help solve a crime or keep it hidden.
The adaptation of Ann Cleeves’s novels uses place as more than scenery. The weather, distance and changing light make the islands feel like an active part of each investigation, while the close community gives every suspect a believable history with the victim. Shetland balances season-long cases with personal continuity, creating a strong binge rhythm without losing the procedural pleasure of interviews and evidence. Its mood is often sombre, and the deliberately spacious pacing will not suit viewers looking for a quick comic mystery. But the series has a stronger emotional and visual identity than most modern police procedurals.
Why it ranks here: Shetland takes the fifth position because it pairs layered characters with a setting that genuinely shapes the crime stories, moving it ahead of the excellent but more contained Dalgliesh. It misses the top four only because its long, bleak investigations can be less playful and less consistently accessible. Fans of atmospheric mysteries, remote settings and character-led British crime will find plenty to sink into. Where to watch: UK listings currently include Sky Go and ITVX Premium, with digital purchase through Apple TV and Amazon Video.

4. Vera
In Northumberland, DCI Vera Stanhope is called to investigate a death that has left a family, workplace or small community full of contradictions. She works with DS Joe Ashworth and a close-knit team, beginning with the practical questions of who last saw the victim and what was missing, then pushing past the answers people offer too quickly. Vera’s blunt manner can make witnesses defensive, but it also helps her see where embarrassment, resentment or grief has bent a story. The series adapts Ann Cleeves’s novels, giving Vera a succession of cases that are rooted in local lives rather than anonymous crime-scene spectacle.
Brenda Blethyn’s performance gives the detective an uncommon mix of abrasiveness and compassion. Vera can appear impatient, even dishevelled, but the show’s empathy lies in how carefully she pays attention to people others have dismissed. The Northumberland landscape gives the mysteries a sense of scale without romanticising the work, and the team dynamic keeps the procedural scenes from feeling mechanical. Some episodes follow the familiar rhythms of British television crime, and the supporting characters can come and go across the long run. Yet Vera’s personality makes those familiar pieces feel specific.
Why it ranks here: Vera reaches fourth because Blethyn’s performance gives an established procedural form a genuinely distinctive lead; the character work and human detail are stronger than the more polished but less personal cases below. It stops short of the podium because the episodic structure can limit the sense of cumulative change. Choose it for humane mysteries, dry humour and a detective who cares deeply even when she refuses to say so. Where to watch: check current UK listings for the series; ITVX and digital purchase offers vary by season.
3. DCI Banks
Detective Chief Inspector Alan Banks leads murder investigations in Yorkshire, where a crime rarely stays within the neat boundaries of its first scene. He and DI Annie Cabbot follow evidence through families, workplaces and communities shaped by personal loyalties and old secrets. The cases may begin with a body, an abduction or a seemingly isolated act of violence, but Banks’s persistence exposes a wider web of motive. His methods can be abrasive, and the strain of the work follows him home, making the central conflict both the case in front of him and the cost of carrying each case into his private life.
The show adapts Peter Robinson’s Inspector Banks novels and takes advantage of their procedural detail without turning every episode into a checklist. Stephen Tompkinson makes Banks compellingly imperfect: experienced enough to recognise patterns, but stubborn enough to create friction with colleagues. Andrea Lowe’s Cabbot offers a strong counterweight, bringing her own judgement and authority to the partnership. Yorkshire landscapes and the show’s restrained look help ground the investigations, while the serial format allows emotional consequences to collect over time. The pacing is not always as taut as the best single-case thrillers, and the series can occasionally lean on familiar police-drama tensions.
Why it ranks here: Banks earns the bronze position for the way its book-derived cases support an evolving detective partnership and a strong regional atmosphere. It is more emotionally continuous than Vera, but just misses the top two because its cases and character beats are less formally inventive than the shows above. Viewers who enjoy British police procedurals with a flawed lead, layered investigations and a Yorkshire setting should put it high on their watchlist. Where to watch: UK availability currently includes Shudder via Amazon Channels, with purchase options on Amazon Video and Apple TV.
2. Inspector Morse
Oxford is the setting for Detective Chief Inspector Endeavour Morse’s investigations, where a murder can lead from a college corridor to a concert hall, a publishing office or a family with long-standing secrets. Morse works with Sergeant Lewis, whose practical patience steadies the inspector’s instinct for literature, music and fine detail. The partnership is central: Morse’s intelligence can uncover patterns others miss, but his pride and loneliness sometimes narrow his view. Each case asks him to interpret a world of class and knowledge as much as physical evidence, while Lewis keeps the inquiry connected to ordinary people affected by the crime.
The long-running television adaptation grows from Colin Dexter’s novels and gives its detective room to become more than a puzzle-solving machine. John Thaw’s Morse is memorable because his culture and certainty coexist with an awkward, sometimes self-defeating temperament. Kevin Whately’s Lewis provides a warm counterpoint and the series steadily makes their working relationship its emotional centre. Oxford is not just a postcard: its institutions and hierarchies create believable motives and pressures. Some episodes are deliberately slow and the show’s intellectual texture can feel more traditional than contemporary thrillers, but its character writing has held up across decades.
Why it ranks here: Inspector Morse places second because it builds one of television’s richest detective partnerships and consistently uses its setting and source material to give mysteries human stakes. It narrowly loses the top spot because the older, more measured style can feel less nimble than the more contemporary reinvention at number one. It is ideal for viewers who love literary clues, long-form character growth and classic British television. Where to watch: ITVX currently offers the series free with ads and through ITVX Premium; digital purchase is also listed.

1. Sherlock
In this modern London, Sherlock Holmes is a consulting detective with an extraordinary eye for patterns and a famously difficult manner. Dr John Watson, a former army doctor adjusting to civilian life, becomes his flatmate and partner after they meet through a mutual acquaintance. Their first case pulls Watson into the police investigation of a suspicious death, and the solution establishes the show’s central rhythm: Sherlock leaps towards an explanation, while Watson’s steadier judgement helps translate brilliance into action. As their cases grow more dangerous, the friendship becomes the human stake beneath each elaborate mystery.
Steven Moffat and Mark Gatiss’s series takes Arthur Conan Doyle’s detective into a world of mobile phones, CCTV, news cycles and online records without losing the pleasure of a carefully constructed clue. Benedict Cumberbatch makes Sherlock magnetic and exasperating; Martin Freeman gives Watson the warmth, frustration and moral balance that make the partnership work. The show’s visual language turns thinking into something viewers can follow, and its London feels busy rather than museum-like. Not every later mystery lands equally well, and the increasingly ornate plotting can sometimes overcomplicate its own emotional turns. Still, the chemistry and pace give it exceptional rewatch value.
Why it ranks here: Sherlock takes the top spot because it combines the clearest premise, the strongest central partnership and the most energetic translation of a classic literary detective into contemporary television. Inspector Morse may be the richer slow-burn portrait, but Sherlock makes the case-and-character engine feel immediately alive for a wider audience, while matching its own ambition with memorable performances and inventive presentation. It is the best all-round recommendation here for viewers seeking sharp modern mysteries, iconic detective chemistry and episodes that invite a second look. Where to watch: UK listings currently include BBC iPlayer, Disney+ and Sky Go; digital purchase is available through Apple TV and Amazon Video.

A Final Word on These Book-Based British Detective Shows
The strongest British detective adaptations treat their source novels as a foundation, not a set of instructions to be followed mechanically. Sherlock relocates a literary icon into a fast-moving digital city; Inspector Morse makes its partnership and Oxford institutions central to the pleasure; Shetland and Vera let regional place and community shape the investigations; while Strike and Dalgliesh find different ways to keep a book’s careful plotting on screen. Across the list, the best mysteries are not only about identifying a culprit. They are about what people protect, what a detective notices and how the process of finding the truth changes the people doing the work.
If you want an easy first watch, start with Sherlock for pace, Grantchester for a gentler mood or Midsomer Murders for a self-contained village puzzle. If you prefer complicated cases and a detective who carries the weight of the work, try Shetland, DCI Banks or Dalgliesh. Our top pick is Sherlock because its lead partnership, contemporary energy and adaptable mystery structure make it the most complete introduction to this particular mix of British television and literary detective fiction. Inspector Morse remains very close behind, and longtime readers may choose it first. Tell us which detective belongs at the top of your own ranking, and which book adaptation we missed.
One pleasant pattern across the list is how varied a British detective show can be: Oxford’s institutional puzzles, Northumberland’s open landscapes, the Shetland islands and Midsomer’s village life all shape investigation differently. The book connection adds another layer, since each series decides what to preserve and what to reshape. Try the pilot that best fits your mood, then follow the detective who keeps you curious.

Frequently Asked Questions
What is the best British detective show based on a book?
For this ranking, Sherlock is the best overall because it makes the Holmes and Watson partnership vivid in a modern setting while retaining the clue-driven appeal of Arthur Conan Doyle’s stories. Inspector Morse is a very close second and may be the better choice if you prefer slower, literary investigations. The “best” pick depends on whether you want contemporary energy, classic atmosphere or a long-running case-of-the-week format.
Which British detective shows on this list are directly adapted from books?
Sherlock is based on Arthur Conan Doyle’s Sherlock Holmes stories; Inspector Morse adapts Colin Dexter’s novels; DCI Banks comes from Peter Robinson’s books; Vera from Ann Cleeves; Shetland from Cleeves’s novels; Dalgliesh from P. D. James; Strike from the Cormoran Strike novels by Robert Galbraith; Grantchester from James Runcie’s books; Wycliffe from W. J. Burley; and Midsomer Murders began with Caroline Graham’s Chief Inspector Barnaby novels. The series may depart from individual stories.
Is Sherlock based on the original Sherlock Holmes books?
Yes. The BBC series is a contemporary adaptation of Arthur Conan Doyle’s Sherlock Holmes stories. It carries over the central relationship between Holmes and Dr John Watson, then relocates the detective work to modern London, where mobile phones, online information and surveillance become part of the cases. It is not a scene-by-scene retelling of every story, so it can work both for longtime Holmes readers and viewers meeting the characters for the first time.
What should I watch after Inspector Morse?
Try DCI Banks if you want another book-based British police procedural with a flawed lead and evolving work relationships. Dalgliesh is a good follow-up for literary mysteries with a thoughtful, restrained investigator. If you want a warmer setting and more humour, Grantchester offers a vicar-and-detective partnership; Shetland is the choice for darker atmosphere and stronger season-long arcs. The right next series depends on whether you want more of Morse’s Oxford mood or a different kind of detective story.
Which show is the easiest binge?
Sherlock is the easiest short binge because its episodes are longer, tightly shaped mysteries and the central partnership is immediately engaging. Midsomer Murders is easier to watch casually because most episodes are self-contained, though its huge catalogue is a much bigger commitment. Strike and Shetland are better binges when you want to follow a case over several episodes and watch relationships change. Check each service’s catalogue, since UK streaming rights shift.
Are these detective shows available on Netflix in the UK?
Availability changes and the current UK listings checked for this guide do not place every title on Netflix. Several are available through BBC iPlayer, ITVX, Disney+, Sky or Acorn TV, and some have digital purchase options. Use a current UK streaming guide such as JustWatch to check the exact show and season before subscribing; a service can carry one series or season without carrying the whole programme.
Where can I stream Sherlock in the UK?
At the time of checking, Sherlock is listed on BBC iPlayer, Disney+ and Sky Go in the UK, with purchase options on Apple TV Store and Amazon Video. Streaming catalogues can change, and availability may differ by season or subscription tier. Check the current title page before planning a watch. If you already use BBC iPlayer, that is a convenient place to begin.
Which series has the strongest setting?
Shetland makes its remote island geography part of the investigative pressure: distance, weather and community ties all shape what the detectives can learn. Vera uses Northumberland’s open landscapes and local communities to ground its cases, while Inspector Morse makes Oxford’s colleges and cultural institutions part of its identity. The setting you prefer depends on whether you want remote noir, northern England or a classic university city.
Are these shows suitable for someone who prefers cosy crime?
Grantchester and Midsomer Murders are the easiest starting points for a gentler, more familiar mystery tone. Grantchester adds a warm central friendship and questions of faith; Midsomer offers self-contained village cases with a slightly playful edge. Vera has dry humour but often deals with darker emotional material, while Shetland, Dalgliesh and Luther-like police thrillers are generally more sombre. Check age ratings and episode descriptions if you have specific content limits.
Why is Sherlock ranked above Inspector Morse?
Inspector Morse may have the deeper slow-burn character portrait, but Sherlock wins this particular ranking because it has unusually strong chemistry between its leads, a distinctive visual approach to clues and a more immediate pace. Its modern setting gives the Holmes formula fresh investigative tools without losing its core appeal. The difference is close: viewers who value literary atmosphere over speed may reasonably put Morse first.
