Some of the greatest sleuths in TV history only exist thanks to American showrunners. Detective shows have been a television staple for decades, but they stand out from simple police procedurals due to their focus on mysteries, episodic cases, and giving particular attention to the investigative process. As such, detective shows don't necessarily need to follow standard police officers— private investigators, oddball consultants, and professors who are experts in their field make just as captivating protagonists.

To that end, British detective dramas have dominated the niche for years, building legacy franchises centered around prestigious main characters like the BBC's Sherlock, Luther, and Agatha Christie's Poirot. Conversely, American crime shows have offered either grittier, more realistic plots or hilariously absurd, lighthearted twists on classic genre conventions. Nevertheless, from the mid 20th century to the late 2010s, American detective shows have shone with a distinctly Western flair and idiosyncratic approach to crimesolving.

10 Veronica Mars

A perfect example of American detective shows highlighting quirky heroes is Veronica Mars, a one-of-a-kind blend of investigative work and teen melodrama. Led by Kristen Bell as the titular Veronica Mars, the neo-noir drama centers on a private eye balancing the unsolved murder of her best friend with the social warfare of high school.

Thanks to its phenomenal cast and enthralling storylines, Veronica Mars gradually became a cult classic TV show, landing a fourth and final season over a decade after its original run on The CW ended. How the series ended was a major point of contention for longtime fans, but even at its most infuriating, Veronica Mars is a masterclass in camp. Year after year, the series attracts new viewers, proving that a truly unique concept is enough to cement a lasting legacy.

9 Bosch

Based on Michael Connelly's series of novels and short stories, Bosch is one of Prime Video's biggest hits to date. The detective drama following the titular Harry Bosch (Titus Welliver) ran for seven complete seasons, earning ubiquitous critical acclaim. The hardened LAPD left such an indelible mark on the television landscape, in fact, sequel show Bosch: Legacy aired a mere year after the original series finale.

Even after Bosch: Legacy drew to a close after three seasons, spinoff series Ballard kept the show's universe alive. Regardless, Harry Bosch remains the true selling point, a fact exemplified by the Bosch franchise expanding with a fourth title— prequel series Bosch: Start of Watch. The flagship series may be pulpy and predictable at times, but that's precisely what most viewers enjoy best about detective dramas: a reliable formula.

8 Magnum, P.I.

Without question, Magnum, P.I. is one of the most formative detective shows of the 20th century. Following the eponymous private investigator Thomas Magnum (Tom Selleck), Magnum, P.I. was a defining title of the 1980s. The cases were kitschy, the characters were endearing, and the Hawaiian shirt and mustache combo was an instantly iconic character design that kept Thomas Magnum recognizable for generations after his prime.

As diverting as the typical episode structure was, Magnum, P.I. knows how to handle real, affecting drama. Details from the titular character's backstory are dispersed throughout startling serious situations, and Selleck's indomitable performances hold up, justifying the show's frequent nominations at the Golden Globes and Primetime Emmy Awards. Of course, the series is merely a reflection of its time— for better and for worse— but Selleck remains the blueprint for countless mustached viewers who keep their eyes peeled for egregiously patterned shirts.

7 Elementary

Its source material may come from a British author, but Elementary puts an American spin on Sir Arthur Conan Doyle's bibliography— and, consequently, stands as the best Sherlock Holmes adaptation ever made. The 2012 procedural turns the acclaimed detective Sherlock (Jonny Lee Miller) into a recovering drug addict who is forced to welcome Dr. Joan Watson (Lucy Liu) into his life as a sober companion.

Despite the show's title, Sherlock (Johnny Lee Miller) only references the eponymous catchphrase once throughout the entire series.

Unsurprisingly, the capricious genius rejects protocol and drags Watson into his chaotic world as a police consultant. Soon, Watson's medical expertise from her days as a surgeon and Sherlock's unmatched powers of deduction prove to be a winning combination, and the pair become unlikely partners-in-crimesolving. Over half a decade since its end, Elementary remains the gold standard for Sherlock-inspired series— and a career highlight for its main characters.

6 Monk

Arguably marking the start of the USA Network's golden age, Monk is a classic procedural with enough personality to spare. Chronicling the life, career, and 312 phobias of Adrian Monk (Tony Shalhoub), Monk typically follows a traditional whodunit set-up, allowing the viewer to put together the clues alongside the private detective week after week.

The familiarity of Monk's routine makes the series an exceptionally cozy crime drama, but the show nevertheless allows the characters to have nuance and inner motivations. Unlike many similar contemporaries, Monk allows its ensemble to grow and change over the course of its eight seasons, and the result is a heartwarming journey of mystery and personal milestones.

5 Psych

Countless detective dramas take themselves far too seriously. Psych, in stark contrast, is an endlessly charming take on the Sherlock & Watson archetype with a faux supernatural spin. After years of being subjected to lectures, demonstrations, and field exams to make him the perfect detective, Shawn Spencer (James Roday Rodriguez) stumbles into a job as a consultant for the Santa Barbara Police Department— the only caveat being everyone believes he's a psychic.

Alongside his childhood best friend Burton "Gus" Guster (Dulé Hill), Shawn must continue the whimsical ruse while solving case after case. Practically every episode ends with a detailed wrap-up that is equally silly as it is savvy, but the true pull is Psych's incredible cast. With storylines that could easily veer into corny territory, the fantastic ensemble keeps the show grounded, forming an unconventional found family as they bond over unsolved murders and niche pop culture references.

4 True Detective

Although later installments were met with mixed reviews, True Detective season 1 is widely agreed to be one of the greatest American shows of the century. The first entry in the anthology explores a 17-year Louisiana State Police investigation led by Detectives Rustin "Rust" Cohle (Matthew McConaughey) and Martin "Marty" Hart (Woody Harrelson). Via a nonlinear narrative, True Detective season 1 follows the near 20 years the pair spend chasing an ominous serial killer with ties to the occult.

Critical Response to True Detective
Season	Rotten Tomatoes Score
Season 1	91%
Season 2	47%
Season 3	84%
Season 4 (Night Country)	93%

The subsequent three seasons all touted star-studded casts, new principal settings, and unique cases, but True Detective season 1 is an uncontested work of art. Luckily, the anthology is on an upswing, as True Detective: Night Country (season 4) is just as sublime in its own right, and a fifth season is currently in development.

3 Mindhunter

Likewise, Mindhunter is far from the average detective show, but it is inarguably a masterpiece crime thriller. Inspired by a true-crime book recording the FBI's history of behavioral science and analysis, Mindhunter serves as the spiritual predecessor to shows like Criminal Minds, which focus on the psychology of serial killers.

In the hit Netflix original series, the spotlight stays mainly on FBI Agents Holden Ford (Jonathan Groff) and Bill Trench (Holt McCallany) as they research criminal psychology by conducting harrowing interviews with real-life killers, a project overseen by Anna Torv's Wendy Carr. Undoubtedly, Mindhunter is its own brand of unsettling, but it represents the new, cutting-edge era of detective dramas.

2 Columbo

Nearly 60 years after its series premiere, Columbo has one of the most likable detectives in the genre's entire history. The titular Lieutenant Frank Columbo (Peter Falk) is disarming, bumbling at times, and seemingly too affable to intimidate the killers he investigates. Yet, Columbo is merely hiding his genius intellect, something the eagle-eyed viewer can only catch glimpses of.

Whereas Columbo as a character is a bold rejection of typical TV detectives, the series itself subverts what many fans had come to expect from the genre. Rather than keep the viewer in the dark, Columbo shows the audience the murderer at the start of every episode, and the rest of the story is just a matter of how the central detective will bring the high-powered criminals to justice. Over half a century later, Columbo continues to influence new age detective shows, most recently with Peacock's Poker Face.

1 Murder, She Wrote

If there was one detective show that best represented American television, it would certainly be Murder, She Wrote. The 1984 drama is the embodiment of everything that makes American detective shows so special. Jessica Fletcher (Angela Lansbury) isn't a stern and stoic police chief; she's a former English teacher and celebrated mystery novelist. Rather than assert that the police force is an infallible proponent of justice, Murder, She Wrote admits that there are flaws in the country's criminal justice system. Even the eponymous murder cases never feel overwhelmingly bleak or upsetting.

Jessica Fletcher is assuredly one of the most talented TV detectives of all time, and Murder, She Wrote is as comforting as it is captivating. In a world where most detective shows are devastating, disturbing, or deeply stressful to watch, Murder, She Wrote is a reminder that the genre doesn't need to rattle the viewer to leave a good impression. If anything, the levity is what makes so many American TV shows that much more enjoyable to watch— even if you're watching people solve a grisly murder.
