Detective shows are perhaps the most timeless of all television’s innovations. Since the early years of serialized television, fans have spent endless hours watching heroic detectives solve complex mysteries, deliver justice, uncover dangerous conspiracies, and defend the good from the evil. Many of these crime mystery shows have run for multiple seasons, becoming some of the longest-running crime shows on TV, which naturally leads to some seasons or episodes that dip in quality. But there are still many that have excelled in every season, bringing fresh stories, consistently stellar performances, and highly rated production values year after year.

These are the detective shows that rank as the finest of the genre and are remembered as legends of the small screen, as are the detectives from these shows, who are cultural icons of their own. From beloved classics to critically acclaimed modern gems, here’s our ranked selection of stellar detective shows that have no bad seasons.

8 ‘Magnum P.I.’ (1980–1988)

A classic '80s TV show that made Tom Selleck into a global TV legend, Magnum P.I. stars Selleck as the titular ex-military officer working as a private investigator and solving crimes across Hawaii. Unlike conventional TV detectives, Thomas Magnum lives a luxurious life as a permanent guest at a sprawling beachside estate owned by a wealthy author, where he enlists the help of his veteran friends and the estate’s stiff-upper-lipped English manager to solve his cases. John Hillerman, Roger E. Mosley, and Larry Manetti play the other main characters.

Created by Donald P. Bellisario and Glen A. Larson, Magnum P.I. was a unicorn of its genre at the time and relied on its self-contained stories that feel consistently refreshing in every season. It instantly gained attention for swapping grim for glossy and presenting a charismatic detective who is also grounded, which became the winning formula for the show. A detective show that made aloha shirts and thick mustaches trend in the '80s, Magnum P.I. is a cultural touchstone of its time and an American television landmark.

7 ‘Monk’ (2002–2009)

A multiple Emmy Award-winning crime series created by Andy Breckman, Monk follows the titular former San Francisco detective, Adrian Monk, whose wife’s mysterious death aggravates his existing phobias and obsessive-compulsive disorder. Known for his unique crime-solving methods and strange insights, Monk becomes an outside consultant working with the SFPD, while investigating his wife’s murder and being perpetually annoying about his afflictions. Tony Shalhoub leads the cast, immortalizing the character of Monk, with Ted Levine, Bitty Schram, Jason Gray-Stanford, and Traylor Howard as other main cast members.

Balancing between a sharp detective and a hyper-eccentric man with debilitating issues, Adrian Monk completely subverts the image and expectations of a hero detective, bringing a whole new angle to conventional police procedurals. Headlined by great performances from the main cast, every season of Monk is a delight with its unconventional hero, interesting crime stories, and even more interesting investigative techniques. Ranking among the best crime shows of this century, Monk is as cozy, comforting, and abundantly hilarious as a detective series can get.

6 ‘Mindhunter’ (2017–2019)

Joe Penhall’s adaptation of John E. Douglas and Mark Olshaker’s non-fiction book Mindhunter: Inside the FBI's Elite Serial Crime Unit, Netflix’s Mindhunter is a dramatized retelling of how the FBI established its Behavioral Science Unit in the 1970s. The series focuses on agents Holden Ford and Bill Tench and psychology professor Wendy Carr, who interview imprisoned serial killers for character profiling and use the results for current cases. Jonathan Groff, Holt McCallany, and Anna Torv star as the leading trio, with Cotter Smith and Hannah Gross as other key characters.

Mindhunter puts a chilling spin on traditional detective shows with its depiction of horrific real-life incidents and major crimes that have left the public shaken for decades. A perfect true-crime show without being tropey or clichéd, the Netflix true-crime series maintains a high standard of storytelling and compelling performances in every season. A highly regarded detective series, Mindhunter is deeply analytical and psychologically immersive, leaving a lasting impression with each story.

The Case File Is Complete Your Nemesis Is…

Four criminal masterminds. One of them was always going to be yours. Here is who comes for you, why they picked you out of everyone available, and what they want from the encounter.

Hannibal Lecter

Your nemesis does not want to beat you. He wants to know you completely, and he is patient enough to wait for it. The frightening part is how good the conversation is.

• Lecter is the most dangerous kind of opponent: the one who finds you interesting. He never raises his voice, because he has never needed to.
• You keep a great deal to yourself and you are careful about what you show. That reserve is exactly the door he would knock on.
• The films understood something other thrillers missed. The horror is not the violence. It is being perfectly understood by the wrong person.
• He would be unfailingly polite about all of it. That is the worst part.

The Joker

Your nemesis is not after money, territory or revenge. He is after a demonstration, and you are the person he has chosen to prove his point on.

• The Joker only picks opponents who believe in something. Your decency is not a defence against him. It is the entire reason he showed up.
• He has no plan you can predict and nothing you can take away, which removes every tool you would normally reach for.
• His whole argument is that you are one bad day away from being him, and you would spend the rest of your life proving him wrong.
• He would call it a magic trick. You would call it the worst night of your life.

Moriarty

Your nemesis respects you, which sounds flattering until you work out what it means. He chose you because nobody else was worth his time.

• Moriarty is the original criminal mastermind, the template every later one borrows from: a mind the equal of the hero's, pointed the wrong way.
• You enjoy being the cleverest person in the room. He is counting on exactly that, and he has already built the room.
• This is the rare nemesis who would be genuinely disappointed if you lost badly. He needs the game to be worth playing.
• It ends the way these things always end. Two people, one problem, and only one way down.

Anton Chigurh

Your nemesis has no personal interest in you whatsoever, and that is precisely what makes him unsurvivable. You are not a rival. You are a stop on the way.

• Chigurh does not negotiate, gloat or explain. He arrives, he asks one question, and the answer was decided long before you opened your mouth.
• You trust yourself to handle things. He is the one problem in the world that has no interest in how capable you are.
• No Country for Old Men rewrote the screen villain by removing the thing audiences quietly rely on: the sense that talking might work.
• Call it. He will wait.

5 ‘Poker Face’ (2023–2025)

Rian Johnson’s crime comedy series starring Natasha Lyonne as the central character, Poker Face follows Charlie Cale, a casino employee and bona fide human lie-detector whose exceptional talents get her in trouble, forcing her to go on the run. Driving her beaten-down Plymouth Barracuda, Charlie travels across the country, making new friends and solving a new homicide at every stop. Benjamin Bratt, Rhea Perlman, Simon Helberg, and Steve Buscemi have recurring roles in both seasons, alongside a long list of guest stars.

A wonderful nod to detective TV classics like Columbo, Poker Face is a high-spirited howcatchem mystery stylized like a case-of-the-week procedural, which has garnered widespread acclaim and a massive audience since its premiere. Lyonne steals hearts and attention as the quirky, drifting detective who charms with her personality and wins with her sleuthing skills. Deeply rooted in modern Americana, every episode of Poker Face brings a fresh case and a new setting, staying relevant in every episode and never losing the audience at any point.

4 ‘Elementary’ (2012–2019)

A modern update on Sir Arthur Conan Doyle’s Sherlock Holmes stories, Elementary finds the London detective in 21st-century New York City, reimagined as a recovering addict. Along with his sober companion-turned-professional partner, Dr. Joan Watson, Holmes helps the NYPD solve crimes while navigating his conflict with his arch-nemesis and former lover, Jamie Moriarty. Created by Robert Doherty, the ABC show stars Jonny Lee Miller as Holmes and Lucy Liu as Watson, with Aidan Quinn, Jon Michael Hill, and John Noble as main characters.

Elementary is not just a reinvention of Sherlock Holmes but a quiet tribute to the motifs and themes of the original mystery literature classics. While the show retains the original character names, it explores completely new cases every week with original characters and stories that keep every episode fresh and unpredictable for the audience. An exciting and high-energy detective show, Elementary is critically praised for the satisfying narrative and its unique personification of Sherlock Holmes.

3 ‘The Wire’ (2002–2008)

A crime television legend, David Simon’s The Wire is not a conventional detective show and involves a wide range of investigations within different institutions of the city of Baltimore. The story is told primarily from the POV of a renegade cop, Jimmy McNulty, whose investigation of the local drug lord and his right-hand man sparks a chain of events that expands to various city departments. All five seasons star Dominic West, John Doman, Lance Reddick, Wendell Pierce, and Andre Royo as main characters.

One of the best crime shows of the 2000s, The Wire has been lauded for its impressive writing and surprisingly accurate depiction of society, politics, and urban life in modern America. The show shifts from standard police procedural tropes and uses the interconnectedness of every city institution to drive individual character arcs, with the city of Baltimore as the main protagonist of the story. The result: an engaging, new chapter unlike anything you’ve seen before in every single season.

2 ‘Sherlock’ (2010–2017)

In BBC’s Sherlock, Steven Moffat and Mark Gatiss reimagine the original canon of Sherlock Holmes stories by Sir Arthur Conan Doyle in 21st-century London, where Sherlock is a quirkier and more eccentric truth seeker and crime solver. With the help of his new roommate turned friend and confidante, Dr. John Watson, and the latest tech he can get his hands on, Sherlock helps Scotland Yard solve the most unsolvable modern crimes. Benedict Cumberbatch stars as Sherlock and Martin Freeman as Dr. Watson, with Rupert Graves, Una Stubbs, and Gatiss appearing in key roles across all four seasons.

A brilliant 21st-century interpretation of the legendary British detective, Sherlock thrills, awes, and excites fans with slick plots, sleek tech, and plenty of pop culture references. The show is noted for its tight-knit storytelling and incredible cinematography in every season. Each only features a few episodes, all of which are sharply written and perfectly acted. Despite the criticisms and controversies surrounding the later seasons, Sherlock remains a fine modern adaptation of Sherlock Holmes anchored by Freeman and Cumberbatch’s unmatchable chemistry, and even its relatively worse seasons are genuine masterpieces.

1 ‘Agatha Christie's Poirot’ (1989–2013)

Initially adapted by Clive Exton and Brian Eastman, Agatha Christie’s Poirot is a serialized TV adaptation of Agatha Christie’s classic mystery novels featuring the famous Belgian detective, Hercule Poirot. Starring David Suchet as Hercule Poirot, the series follows his pursuits across the continent and beyond, solving twisted crimes solely with the help of his ingenious mind and methods, and sometimes with the help of his friends, Captain Arthur Hastings, Inspector James Japp, and his efficient secretary, Miss Felicity Lemon. Hugh Fraser, Phillip Jackson, Pauline Moran, and Zoë Wanamaker appear as supporting characters, with a revolving guest cast of notable stars.

One of the biggest highlights of Poirot is Suchet’s perfect personification of the iconic detective, which keeps fans coming back episode after episode, season after season. Running for 13 seasons in total, the show is the only screen adaptation of Poirot stories to feature nearly every original novel and short story. Designed and crafted true to the source, Poirot is a perfectly cozy mystery that brings life to some of Christie’s most essential crime novels.
