The best murder-mystery movies of all-time to test your sleuthing skills to the max

Sleuth: Sherlock Holmes (Peter Cushing)

Sleuthing style: Bristling and brilliant.

Hammer Films director Terence Fisher teamed up with his Dracula stars Peter Cushing and Christopher Lee on the moors of Devon (okay, Chobham Common) for the daddy of all Sherlock Holmes yarns. If you’re not familiar, a savage canine is roaming Dartmoor and Holmes and Watson (André Morell) are charged with finding out who it will kill next and why it’s probably the heir to a huge country pile (Lee). It’s basically Scooby-Doo, only the Great Dane is the bad guy. Cushing’s Holmes is a feisty, sophisticated version of Conan-Doyle’s creation and Morell’s Watson is at the less fuddy-duddyish end of the sidekick spectrum, as the pair sift through the red herrings galore. The results are deeply moor-ish. 

Sleuths: Detectives Park (Song Kang-ho) and Seo (Kim Sang-kyung) 

Sleuthing style: Highly sackable.

For many, Bong Joon-ho’s greatest film – superior even to Parasite – this masterful, jack-knifing crime procedural operates in a fog of almost Proustian melancholy as it revisits the story of Korean’s first ever recorded serial killer. Bumbling rural cops Park and Cho are joined by a slicker Seoul detective, Seo Tae-yoon, who soon finds himself dragged down to their level as the bodycount of murdered women grows and the rule book goes out the window. Suspects are beaten, red herrings swallowed whole and the price of blundering is paid in corpses. It’s bleakly funny, in Bong’s hallmark style, but deadly serious too – a cinematic autopsy performed on a desensitised society. 

Sleuth: LB Jefferies (James Stewart) 

Sleuthing style: Voyeuristic.

Sleuth: LB Jefferies (James Stewart) 

Sleuthing style: Nosy.

Constructing a heart-palpitating thriller that takes place almost entirely in one room and from a single point of view is no easy task, but then, they don’t call Alfred Hitchcock the master of suspense for nothing. Homebound due to a broken leg, photojournalist LB Jefferies begins taking an interest in the lives of the folks in the neighbouring apartment complex – and eventually becomes convinced one of them has committed a grisly crime. Hitchcock had dabbled in minimalist, play-like setups before – see 1948’s Rope – but all things considered, Rear Window just might be his greatest achievement, as he proved he could achieve almost queasy levels of stress and tension even while working within the barest narrative constrictions. Not to mention that its themes of urban isolation and voyeurism hit even harder in the post-pandemic world, now that we’ve all had our own experiences being confined to our homes, with little more to do for entertainment than stare a bit too long out the window. 

Sleuth: Detective Takabe (Kōji Yakusho)

Sleuthing style: Psychologically spiralling. 

Kiyoshi Kurosawa’s influential chiller sees a spate of bloody murders committed by otherwise oblivious people experiencing a form of mind control (think Tom Riddle’s diary, only way, way gorier). Bong Joon-ho has admitted his debt to it, and you can feel the connective tissue between his films and this ice-veined, almost supernaturally charged procedural in its exploration of murder’s capacity to claim victims even of the still-living. Here, it’s detective Kenichi Takabe (Kōji Yakusho), who finds a likely suspect, the seriously creepy Mamiya, and tries to find out if he’s behind all the corpses left with a ‘X’ carved into their necks. 

Sleuth: Mark McPherson (Dana Andrews)

Sleuthing style: Obsessive. 

More than a decade before Hitchcock’s love struck vertiginous detective, Otto Preminger’s iconic film noir Laura also pursues necrophiliac themes. Unruffled police lieutenant McPherson is surrounded by the pseuds and hangers-on who inhabited the life of a eponymous woman whose murder he’s investigating. Gene Tierney’s Laura shines in a world of witty fakery and the movie is pervaded with a stately wistful melancholy that the detective can never meet the woman he falls for, only solve her crime. Like Vertigo, the motifs of portraits and musical refrains remind us that as audience, we are also subject to the sliding doors and manipulations of noir obsessions. Just that it’s the films that haunt us.

Sleuth: Robert Graysmith (Jake Gyllenhaal)

Sleuthing style: All-consuming.

Of the atrocities committed by the Zodiac Killer, the worst is the string of random murders that paralysed the San Francisco Bay Area in the 1960s. Second, though, is the way they turned their identity into a game that ensnared many more victims. It’s the latter that David Fincher is most interested in. Sure, Zodiac contains several brutal recreations of those acts of violence, including the ‘Hurdy Gurdy Man’ opener and the daylight attack on a couple in a park. But the movie’s real focus is on the rabbit hole the killer opened up with the maddening puzzles and clues they left behind.

Sleuths: Inspector Crowe (Denis O’Dea) and Detective Ames (Jack Hawkins)

Sleuthing style: Suspicious.

Murder through the eyes of a child is a truly frightening thing in this masterful Graham Greene adaptation from Carol Reed: a disorientating, traumatising deed with far-reaching consequences – even when it isn’t even really murder. What Philippe, the lonely nine-year-old son of the French ambassador to London, thinks he’s seen when his father’s butler (Ralph Richardson), who he dotes on, and his jilted wife (Sonia Dresdel) tussle at the top of the stairs ends in a police investigation. But what has he really seen and will the police figure out the truth? The procedural element comes late in the day, but The Fallen Idol finally delivers a unique perspective on the genre.

Sleuths: Nick (William Powel) and Nora Charles (Myrna Loy)

Style of sleuthing: Boozy and fast-talking.

The original, and best, of the Thin Man movies introduces Dashiell Hammett’s liquor-loving married couple Nick and Nora Charles, easily the most progressive on-screen couple 1930s moviegoers would have laid eyes upon. She’s every bit his equal but they’re at their best together, exchanging screwball patter, solving murders and slugging back martinis. Here, it’s Nick who comes up with the wheeze of inviting all the suspects round for a dinner party and seeing who snaps. 

Sleuth: Benoit Blanc (Daniel Craig)

Sleuthing style: Kentucky fried.

When it came out, Knives Out scanned like a lightweight palate cleanser for Rian Johnson after shouldering the high stakes of the Star Wars franchise. Instead, it became a phenomenon. Apparently, audiences had been waiting for someone to bring back the old-school, Clue-style murder mystery, and while it wasn’t entirely obvious at the time, Johnson was just the guy to do it – after all, his first movie, Brick, was a throwback noir dressed up as a suburban teen flick. Now years removed from the leftfield hype, and overshadowed in scope by the sequel, the original is still a superior blast. Its plot is basic whodunnit stuff – a wealthy novelist (Christopher Plummer) dies suddenly and everyone’s a suspect – but the execution is flawless, due to a massive A-list cast who have no problem cranking the ham levels to 11. Best among them is Daniel Craig, whose attempt at playing a Southern gentleman is so ridiculous it goes all the way around to being brilliant.   

Sleuth: Miss Marple (Margaret Rutherford)

Sleuthing style: Bastard-mad aunty.

Rutherford played Agatha Christie’s septuagenarian supersleuth on four occasions, beginning with this unalloyed gem that’s located in the early ‘60s by its groovy Ron Goodwin score, if not its line-up of starchy rural suspects who might have stepped out of the war years. Based on Christie’s ‘4.50 from Paddington’, it’s all sparked into action when Marple spots a murder on another train and follows the corpse to a nearby country pile, where she promptly takes a job and gets to work solving it all. Easily the jolliest film in which several people are brutally murdered. 

Sleuth: Philip Marlowe (Robert Mitchum)

Sleuthing style: Frank Drebin with more end product. 

Robert Mitchum plays Philip Marlowe in this wonderfully laconic showcase of Raymond Chandler’s legendary private dick that takes in murdered nightclub owners, missing dames and a few surprise drive-by shootings. The 1944 noir version, Murder My Sweet, has many champions but for us, Mitchum just nails Marlowe’s sardonic line in juicy epithets (‘My bank account just crawled under a duck’) and cop-baiting putdowns (‘I had a feeling you’d be round, so I had the office sprayed’). The plot thickens – and keeps on thickening.

Sleuth: Marge Gunderson (Frances McDormand)

Sleuthing style: Folksy.

Not many movies that include a scene of a body getting fed through a wood chipper take place in a world most of us would be keen to live in, but that’s sort of the point of Joel and Ethan Coen’s only slightly exaggerated version of the American midwest: not even the encroachment of big-city violence can rattle the region’s preternatural niceness. It’s that collision of brutality and unflappable good nature that makes Fargo so absurdly funny. But make no mistake, it’s a great crime film as well, and McDormand’s Gunderson is one of cinema’s all-time great sleuths. A pregnant small-town cop as cheery as her neighbours but much more clever, she allows herself just enough cynicism to believe a dweeby local car salesman (William H Macy) might have something to do with all the random murders happening lately.

Sleuth: Leonard Shelby (Guy Pearce)

Sleuthing style: Forgetful

A common criticism lobbed at Christopher Nolan’s breakthrough feature is that it’s little more than a typical wrong-man thriller gussied up with a gimmicky reverse-chronology narrative structure. Sure, a basic plot synopsis doesn’t make it sound like much: a man suffering from amnesia (Pearce) is framed for the murder of his wife, and must battle against his own damaged memory to find the real killer. But that’s like saying The Godfather Part II would be just another crime story without its dual timelines, or 2001 is a basic sci-fi flick that just happens to have a 20-minute psychedelic freakout in the middle. It’s not some cheap marketing ploy – it’s what makes the movie what it is. It’s a conceit that challenges the viewer’s own memory, and demands they pay attention in order to piece the mystery together. And in an era of passive movie watching, that makes the device not just cool, but almost crucial. 

Sleuth: Sherlock Holmes (Christopher Plummer)

Sleuthing style: Anti-establishment. 

Christopher Plummer and James Mason only made one film together as Holmes and Watson but, boy, is it a humdinger – one of the finest of the 250-odd Holmes movies so far committed to screen. The fire in Holmes’s heart is well and truly kindled by the Ripper murders of East End prostitutes, a series of brutal crimes that lead him into a far-reaching conspiracy and bring out the avenging feminist in this violin-playing, pipe-puffing super brain. Watch it then delve into the source material, Stephen Knight’s famous book ‘Jack the Ripper: The Final Solution’.

Sleuth: Wadsworth (Tim Curry)

Sleuthing style: Cheeky. 

A movie based on a board game? Wow, Hollywood has really run out of ideas, haven’t they? Three decades before Battleship, British director Jonathan Lynn took on the challenge of adapting a different Hasbro property, and against all logic, it actually worked out – in the long run, anyway. Met with derision from critics and middling box office, the film’s stature is now at least equal to the game itself. Taking the game’s basic set-up – six strangers are called to a mysterious mansion, a seventh ends up dead and everyone’s a suspect – and adding winking humour, Cold War paranoia and a delightful Tim Curry as the suspicious butler trying to sort it all out, it leads to a conclusion that’s either brilliant or totally daft. At any rate, the movie has proven more influential than anyone would’ve predicted: when critics say Rian Johnson revived the murder mystery with Knives Out, what they really mean is he just remade Clue for the 21st century.

Sleuth: Hercule Poirot (Peter Ustinov)

Sleuthing style: Conducted either aside of an evening sundowner.

Here’s a question: if someone gets murdered on Poirot’s holiday, does it still count as annual leave? The Belgian super-sleuth is just after a serene cruise down the Nile in this an all-star take on Agatha Christie’s potboiler, when wouldn’t you know it? The rich woman everyone else on board hates is mysteriously shot in the face. Zuts, and indeed, alors. With his customary methodical elan and bushy moustache glinting in the Egyptian sun, Poirot gets to work solving the case. All he knows is that it’s not David Niven. But it could be a batty Bette Davis, a testy Maggie Smith or a brittle Mia Farrow. It almost doesn’t matter, so much cheesy fun is it watching them all duke it out.

Sleuths: William Somerset and David Mills (Morgan Freeman and Brad Pitt)

Sleuthing style: Murtaugh and Riggs on a really bad day.

Climaxing with history’s most disturbing unboxing video, David Fincher’s first movie about a serial killer taunting police officers is still the grimmest, grimiest thing he’s ever done. Where most of his films derive chills from alienating sleekness, Seven – so named for its villain’s high-concept murders based on the seven deadly sins – is downright filthy, with dessicated corpses found in blood-smeared apartments and death coming via burst stomachs and spiked sexual apparatuses. Despite all the gore, the scariest scene remains that last one, rendered through mere suggestion and Brad Pitt’s freaked-out reading of the line, ‘What’s in the boooooxxxxxx?!’

Sleuth: Sherlock Holmes (Nicholas Rowe)

Sleuthing style: Know-it-all.

In his own Goonies-style way, the teenage Sherlock offers a sparkling addition to the crime-solving canon in this boisterous origin caper from Barry ‘Rain Man’ Levinson and Amblin. You can tell Young Sherlock’s adventures are penned by Harry Potter’s Christopher Columbus, such is the Hogwartsy vibe of its public school setting and imaginative detours into the realm of magic. But there’s lots of fun to be had as the schoolboy Sherlock and his sidekick Watson go on a roundabout hunt for a fairly obvious set of villains and demonstrate that murder-mysteries can be playful as well as nerve-fraying. The game, as they say, is afoot! 

Sleuth: Inspector Lohmann (Otto Wernicke)

Sleuthing style: Avuncular.

German auteur Fritz Lang invented, like, a half-dozen genres with his first talkie, 1931’s M, including the psychological thriller, the police procedural and the film noir. By his next film he was already mixing them together to make something entirely different. Lang had introduced the titular criminal mastermind – the creation of novelist Norbert Jacques – a decade earlier in the four-hour Dr Mabuse the Gambler. In the sequel, he’s locked in a mental asylum, but that doesn’t stop him from using mind control to get others to do his bidding, of which murder is only one element. It’s up to another member of the Fritz Lang Cinematic Universe to figure out his ultimate plan: the crafty Inspector Lohmann, who also tracked down Peter Lorre’s disturbed child killer in M. 

Sleuth: Brendan (Joseph Gordon-Levitt)

Sleuthing style: Bruised and battered.

Fourteen years before resurrecting the old-fashioned murder mystery, Rian Johnson resuscitated another antique genre: the old-fashioned noir. Brick, however, was far less of a pastiche than Knives Out and more of a formal experiment. What if suburban millennials all talked like 1940s gumshoes? While the conceit is a bit disorienting and distracting at first, once you’ve settled in, Johnson’s knack for facilitating an engrossing mystery take over, and that odd artificiality becomes strangely immersive. Kudos goes to star Joseph Gordon-Levitt – then primarily known as the kid from the sitcom 3rd Rock from the Sun – who somehow makes the hardboiled dialogue sound totally natural coming from an Orange County high-school student circa 2005. He pulls back on his naturally boyish charisma to play Brendan, an amateur sleuth investigating the death of his girlfriend using the enigmatic clues she left behind – and getting pulled deeper into a shady underworld he may not escape from.     

Sleuths: Jackson Healy (Russell Crowe) and Holland March (Ryan Gosling)

Sleuthing style: Bickering.

Lethal Weapon writer Shane Black knows a thing or two about buddy-cop dynamics, but who would have guessed he’d find another Murtaugh and Riggs in Ryan Gosling and Russell Crowe? Neither had proven comedic chops, yet they each fit this ’70s noir send-up like a polyester suit. The former is a bumbling, brokenhearted private investigator; the latter a heavy with a heart of gold and hands of lead. Fate and the criminal underworld see the duo – along with March’s precocious preteen daughter, played by scene-stealing Angourie Rice – embroiled in a case involving a porno movie, a corporate conspiracy, a missing girl and a pile of dead bodies. It’s a hoot from start to finish, though the real mystery is why we haven’t gotten a sequel yet. 

Sleuth: Sherlock Holmes (Basil Rathbone)

Sleuthing style: Wordle-in-two clever. 

This Hollywoodised take on Sherlock Holmes starts where others would end: with the dastardly Moriarity in the dock at the Old Bailey. Only, wait! He’s released and regroups to plan his most heinous scheme yet. Fortunately, the equally cunning Holmes (Basil Rathbone) and the very much less cunning Watson (Nigel Bruce) stand in his path, complete with clever disguises. Rathbone and Bruce are a wonderful double-act – the former an impatient but rather gentle Holmes; the latter a guileless but bulldog-brave Watson – while George Zucco’s Moriarty has a weird thing for house plants. The McGuffin here is the Crown Jewels, but there’s a murder too: even if it took place ten years earlier. The verdict? An endlessly enjoyable hybrid of American flair and British substance that you can find online for free.

Sleuth: Film director Philip Dexter (James Mason)

Sleuthing style: Bohemian.

Stephen Sondheim and Anthony Perkins’ famously elaborate Manhattan cluefests, put on for showbiz pals, helped spawn this ingeniously plotted but still under-appreciated caper. It was a big influence on Knives Out and its easy to see why in the sheer delight it in the art of breadcrumbing clues throughout and giving each of its ensemble (James Mason, Raquel Welch, Dyan Cannon, et al) their moment. James Coburn’s widowed movie producer invites some Hollywood friends onto his yacht in the Med and then gives them a series of clues to solve, promising to unmask his wife’s killer at the end of week. You can watch it as a straight-up mystery or a biting satire on Hollywood morality and egos. Either way, it’s a tonne of fun.

Sleuth: John Watson (Ben Kingsley)

Sleuthing style: Secretive.

There’s a Homer Simpson/Frank Grimes dynamic to this underrated comedy’s Holmes-and-Watson double act. The twist is that Michael Caine’s Holmes is the front man, an actor with a taste for ladies and liquor, while Ben Kingsley’s Watson is the real brains of the operation, giving up the glory to avoid drawing focus from his medical career but jealous of it too. Predictably, pisshead thesp and pompous brainaic bicker like an old married couple, falling out and splitting up, before teaming up to take on Moriarty and his plot to flood the economy with counterfeit notes. Critics hated it when it came out but do not underestimate the leftfield charm of this anti-bromance – and especially Caine’s line in bullshitting. ‘It is my opinion,’ he notes after some deliberation of one washed-up corpse, ‘...that he is dead.’ No shit, Sherlock.

Sleuth: Inspector Thompson (Stephen Fry)

Sleuthing style: A bit, er, um, bumbling.

It’s not until the 80-minute mark that Sir William McCordle’s (Michael Gambon) corpse is discovered with a whopping great knife in it, and a blood-curdling scream shatters the back-biting and gossip of Gosford Park. It’s not, perhaps, the traditional murder-mystery structure whether the killing comes early and spurs the plot, but Robert Altman’s skewering of the English class system isn’t your standard crime thriller. Trying to figure which of the egregious posh people assembled for a shooting weekend might have killed another of their number is Stephen Fry’s hapless inspector. But honestly, one of the dead pheasants present has a better chance of cracking the case.

Sleuths: Detectives Sean Devine (Kevin Bacon) and Whitey Powers (Laurence Fishburne)

Style of sleuthing: Glum.

Elegantly shot, superbly acted and relentlessly, suffocatingly grim, Clint Eastwood’s Mystic River is a ‘murder mystery’ in the least fun sense of the term. Decades after being splintered by an unspeakable childhood trauma, three friends from a working-class Boston neighbourhood (Kevin Bacon, Tim Robbins and Sean Penn) are forced to reckon with the past when one of their daughters turns up dead. Like we said: not fun. But Eastwood handles the heavy material with grace, creating a tone that’s sombre but not exploitive, and while it’s a hard film to get through, it’s not an experience you regret.

Sleuth: Capt. Finlay (Robert Young)

Sleuthing style: Meticulous.

This Oscar-nominated B-movie brought the stain of antisemitism to the noir genre. The idea of murder motivated by race hate drives a procedural where a group of GIs, including Robert Mitchum and Robert Ryan, are the obvious suspects. On the case is a detective, Capt. Finlay, who neatly articulates why race hate is such a tricky crime to solve in the film’s impassioned closing moments: ‘You usually have to know something about a man to have a reason to kill him. You have to know him well enough to be in love with his wife, or know he has some money.’ Not here. Bad Day at Black Rock, Mississippi Burning and other thrillers would expand on the theme.

Sleuth: Basil of Baker Street 

Sleuthing style: Squeaky.

This is no murder in this loveable animated caper but there is a kidnapping, a dastardly plot to repace the Queen of England with a mechanical version, a tiny airship and a psychotic bat…so we’re counting it. In truth, it plays out almost identically to a murder-mystery in the way its titular crime-solver, Basil of Baker Street, sets about identifying a likely villain (Vincent Price-voiced super-rodent Ratigan) and someone does eventually get fed to a cat. In the spirit of the Sherlock Holmes stories it homages, Basil even gets a doughty sidekick in the bewhiskered shape of war veteran Major Dawson (presumably some kind of mouse war). If you need a break from all the bloodshed, give this one another spin.

Sleuth: Inspector Clouseau (Peter Sellers)

Sleuthing style: Wildly over-confident. 

‘I gather ze facts, examine ze clues and before you know it, ze case is solved!’ If Peter Sellers’s bumbling Inspector Clouseau, a one-man stroke risk for his exasperated superior, Commissioner Dreyfus (Herbert Lom), is half as good as he thinks he is, A Shot in the Dark’s perpetrator would have been apprehended in minutes. As it is, justice isn’t served until Clouseau has set fire to himself, fallen out of a window, knocked a tonne of stuff over and driven Dreyfus into a murderous psychosis of his own. As a detective, he’s hopeless; as a showcase for Sellers’ deadpan physical comedy, he’s sheer genius. 

Sleuth: Inspector Doppler (Alec Cawthorne)

Sleuthing style: Heavily disguised.

You can’t have a murder-mystery list without including the act of theatrical sleight-of-hand that is Sleuth. Adapted by Anthony Shaffer from his own play and directed by All About Eve director Joseph L Mankiewicz, an expert in the field of catty rivalries, it transitions nicely from stage to screen: male ego is main victim here, as Laurence Olivier’s crime novelist tries to avenge himself on the cocksure hair stylist (Michael Caine) who is sleeping with his wife. It was remade (badly) in 2007 with Caine swapping roles and Jude Law playing the lothario, but this twisty chamber piece is camp fun and a nice reminder that a well-crafted crime can take on a momentum all of its own.

Sleuth: Frank Bigelow (Edmond O’Brien)

Sleuthing style: Dying.

Stop us if you’ve heard this one before: a man walks into a police station to report a murder – his own. That set-up probably does sound familiar, even if you haven’t seen Rudolph Mate’s foundational noir about a rapidly dying notary public racing to figure out who poisoned him and why. The film has been remade multiple times, and its then-novel flashback structure is now a common narrative device. The original is still the best, though, twisty and pulpy and ridiculous in the way of most great noirs. (Track it down free on YouTube.) But if you don’t have the patience, at least watch Crank with Jason Statham, which takes the basic premise and pumps it full of crystal meth… like, literally. 

Sleuth: Byomkesh Bakshy (Sushant Singh Rajput)

Sleuthing style: Observational.

The satyanweshi, or ‘truth seeker’, is a sleuth made famous by Bengali writer Sharadindu Bandyopadhyay’s crime novels. In this 1940s-set Hindi thriller that plays out amid the air raids and subterfuge of wartime Calcutta, he’s played by Sushant Singh Rajput – a detective who is hired by the son of a missing scientist to find out what happened to his dad. And he sorts the clues from the red herrings with all the savvy of a Sherlock Holmes-inspired character to keep the bodycount down to reasonable levels. 

Sleuth: Jack Terri (John Travolta)

Sleuthing style: Paranoid.

If the title sounds familiar, that’s intentional: Brian De Palma’s pitch-black neo-noir is an undisguised homage to Blow-Up, Michelangelo Antonioni’s ‘60s arthouse classic about a photographer who captures a murder on film. Only here, it’s a movie sound tech who believes he’s recorded audio of a presidential candidate’s assassination. But Blow-Out isn’t just a remake with updated tech: De Palma folds in plenty of early ‘80s-specific anxiety about the post-Watergate political landscape. It also has a great, paranoid performance from John Travolta, proving for the first time that he could do more than look cool doing the Brooklyn Shuffle in satin pants. 

Sleuth: Superintendent Robert Hazard (Nigel Patrick)

Sleuthing style: Quietly professional. 

A young light-skinned woman called Sapphire is found stabbed to death on Hampstead Heath. But is it a random killing or racially motivated? Director Basil Dearden regularly took a scalpel to London’s prejudice-strewn underbelly with films like Pool of London and Victim, and this hard-hitting drama – a kind of British answer to John Cassavetes’ Shadows from the same year – takes no prisoners in ripping into white Britain’s racist id. The often debonair Nigel Patrick gets serious as a methodical cop who keeps prodding away until the poison eventually spills out. 

Sleuth: Detective Blore (Roland Young)

Sleuthing style: Severely comprised.

There’s a few things characters in a murder-mystery should never do: take a boat trip to a remote country house, take the first sip of wine and try the curry (it’ll be an arsenic jalfrezi, guaranteed). Most of these elementary errors are made in a joyfully hammy take on Agatha Christie’s ‘Ten Little Indians’, but mainly because that many people are murdered. It’s basically Saw in evening wear, with a mysterious figure overseeing the well-mannered slaughter. Some of the acting is a touch stiff, though the presence of the great Walter Huston as a shady doctor elevates things, and René Clair’s brisk direction keeps the bodies flowing. 

Sleuths: Ed (Jack Lemmon) and Beth Horman (Sissy Spacek)

Sleuthing style: Fearless.

Okay, it’s not really a murder mystery – at least, not in the conventional sense. In fact, if you were looking to find a pigeonhole to slot Costa-Gavras’s angry post mortem of Chile’s 1973 right-wing coup, political thriller would be the obvious one. But all the ingredients of the genre are here: two amateur investigators (ageing American Ed Horman and his daughter-in-law Beth), a disappearance that surely signifies murder (Ed’s son and Beth’s husband, journalist Charlie) and a crime scene (Santiago, in the aftermath of violent military repression). What’s different here is the wild power imbalance: these two brave souls just want closure; they have no leverage and no way of bringing the culprits to book. The culprits, after all, run the show. 

Sleuth: Philip Marlowe (Elliott Gould)

Sleuthing style: Cool, man. 

Critics absolutely hated Robert Altman’s ‘70s remix of Raymond Chandler, calling his version of one of the writer’s most-loved novels a ‘lazy, haphazard putdown’ and Gould’s take on film noir’s coolest detective as ‘an untidy, unshaven, semiliterate, dimwit slob’. Altman couldn’t have been too surprised by the reception: by making Marlowe a man out of time – an old-school gumshoe who no longer understands the world around him – he was effectively interrogating the relevancy of the noir genre itself. Over time, however, The Long Goodbye has come to be seen among the best and smartest Chandler adaptations, and its story – of Marlowe looking into the suspicious alleged suicide of a good friend – still holds up.

Sleuth: Inspector Cockrill (Alastair Sim)

Sleuthing style: Jovial but intense. 

Inspector Cockrill of Kent County Police, played with comic gusto by the inimitable Alastair Sim, is a refreshingly maverick entry to the crime-busting canon. He’s not above getting things horribly wrong but somehow stumbles on his man (or woman) in the end. The only shame is that this is the only one of crime writer Christianna Brand’s Inspector Cockrill tales to get the movie treatment, so much fun is Sim’s hammy sleuthing. The crime he’s charged with solving is a possible murder during an operation at a wartime hospital. Trevor Howard is one of the suspicious medical types who may have switched the anaesthetic canisters.

Sleuth: Philo Vance (William Powell)

Sleuthing style: Suave and in charge.

The Thin Man star William Powell’s other sleuthing franchise doesn’t have the snappy patter, cute pooch or lightness of touch of his Myrna Loy team-ups. But the first of these Philo Vance films still boasts the satisfying crime-solving rigour you’d expect from a Dashiell Hammett adaptation. The titular Canary is Louise Brooks’s ruthless showgirl, who blackmails one lover too many and ends up strangled. Vance cunningly lures the suspects into a game of poker to see which of them boasts the coolness and daring to have pulled off a murder. Another crime here is the dubbing that turned this silent film into a clunkly dubbed talkie (Brooks refused to record her lines and was replaced by another actress).

Sleuth: John Wintergreen (Robert Blake)

Sleuthing style: Easy Rider.

Like a countercultural CHiPs, this ’70s actioner shot by the great Conrad Hall follows quirky, pint-sized motorcycle cop John Wintergreen and his Harley-Davidson Electra Glide in pursuit of a killer around Monument Valley. He’s a straight arrow who believes in justice, not a hippie-basher like some of his peers in blue, but he’s still an unusual figure to root for in a Vietnam-era movie. But Robert Blake inhabits him with a strange nobility as figures out that a suicide is not what it seems, and neither is the authoritarian system he’s supposed to be enforcing.
