As the summer winds down and the cooler seasons stumble in, nothing beats a good book with a riveting, page-turning conspiracy. No matter the era you pull from, the detective novel has been a part of our Western canon for over a century, and there's a reason we always find ourselves returning to it. Whether you love shows like Agatha Christie's Poirot or BBC's Sherlock, it's likely that you'll find yourself enveloped in a good, old-fashioned mystery sooner or later — so why not start with the classics? Detective fiction is a cerebral experience that pushes the reader to better understand not just the psychology of others, but of oneself. Discerning the deceptions and putting the pieces together requires skill and attentiveness. So, if you want the most essential detective stories to start with, look no further than these five thrillers that will keep you on the edge of your seat. While each of these tales has been adapted at some point or another for the screen (either as a major motion picture or a television miniseries), we'd encourage you to give them a read first. If you've already seen the movie, you'll probably still get a kick out of the original too! 'The Big Sleep' (1939) Image via Penguin When it comes to hard-boiled detective stories, there's no better place to start than with Philip Marlowe. Raymond Chandler's The Big Sleep is not only one of the most famous detective novels, but it produced one of the greatest noir pictures ever made, featuring the stunning duo of Humphrey Bogart and Lauren Bacall. The tale follows the LA-based private eye after he is hired by General Sternwood to deal with a bit of blackmail that's found its way to his younger daughter. Of course, that's only the beginning of the mystery, as Marlowe is soon thrust into a strange landscape full of morally bankrupt characters and deceptive femme fatales. The Big Sleep is full of unforeseen twists and turns that make for a rocky (but enjoyable) read. Marlowe is somehow the most decent person in the narrative, as the wicked actions of all those involved in this budding criminal conspiracy come to a horrid light. Los Angeles itself is depicted almost as a living, breathing entity that pushes its residents to further depths of depravity than the reader might think possible. Like the best mysteries, it's a study in the complexity of human nature. Just, whatever you do, don't watch the '70s adaptation — it may be more faithful to the ending than the iconic '40s film, but that's about all it has going for it. 'Murder on the Orient Express' (1934) Image via William Morrow Speaking of studies in human nature, perhaps no mystery novel is as famous as Murder on the Orient Express. A Hercule Poirot novel by the "Queen of Crime" herself, Agatha Christie, the tale is about exactly what you would expect. When shady American businessman Samuel Ratchett is suddenly killed, the train is stopped by sudden snowfall, prompting Poirot to do what he does best. The investigation is quite thrilling, with more possible suspects than the detective could have thought all in the same closed compartment. Even if you already know the ending, you'll find yourself quite enthralled by how Poirot reaches his conclusions. Plenty of live-action Poirot's have tackled this case (making some cozy on-screen mysteries for those who love the genre), but nothing quite compares to Christie's literary classic. Murder on the Orient Express is classic detective fiction that doesn't hit the brakes. The mystery itself was partially inspired by the Lindbergh kidnapping in 1932, prompting Christie to weave a crime novel the only way she could. Poirot is in rare form too, once again commanding every scene with his keen wit and unusual appearance, solving this case with the dogged determination of a man completely obsessed with putting the puzzle together — and you'll be just as obsessed with reading it. 'The Hound of the Baskervilles' (1902) Image via George Newnes Ltd Despite the popularity of Sherlock Holmes himself, Sir Arthur Conan Doyle only wrote four novels starring the character — the rest of your favorite Sherlock stories were all short stories. Of the novels, The Hound of the Baskervilles is arguably the most famous, and for good reason. Although first published as a serial in The Strand Magazine as the protagonist's first appearance following his supposed death (in "The Final Problem"), the tale was later collected and published in book format in 1902, changing the game forever. It's no wonder the character's popularity never waned after his death, since Doyle proved himself a master of his craft again here. As Holmes and Watson look into a local West Country legend about a devilish hellhound, they must protect the Baskerville family from this supposed curse. Is this a real supernatural force, a folktale that has struck fear into the hearts of men, or something else? That's exactly what our hero has set out to uncover. With brilliant pacing and suspense that could kill, The Hound of the Baskervilles is often considered a piece of detective fiction that is perfect from the first page to the last. It's also among the most adapted Doyle stories, having been remade as a major motion picture several times and re-imagined on shows like Sherlock and Elementary. Collider Exclusive · TV Medicine Quiz Which Fictional Hospital Would You Work Best In? The Pitt · ER · Grey's Anatomy · House · Scrubs Five hospitals. Five completely different ways medicine goes sideways on television — brutal, chaotic, romantic, brilliant, and ridiculous. Only one of them is the ward your instincts were built for. Eight questions will figure out exactly where you belong. 🚨The Pitt 🏥ER 💉Grey's 🔬House 🩺Scrubs FIND YOUR HOSPITAL → 01 A critical patient comes through the door. What's your first instinct? Medicine under pressure reveals who you actually are. AStay completely present — block everything else out and work through it step by step, right now. BTriage fast and delegate — get the right people on the right problems immediately. CTrust my gut and move — I work best when I stop overthinking and just act. DAsk the question everyone else is ignoring — what's the thing that doesn't fit? ETake a breath, make a joke to cut the tension, and then get to work — panic helps no one. NEXT QUESTION → 02 Why did you go into medicine in the first place? The honest answer says more about you than the one you'd give in an interview. ABecause I wanted to be where it matters most — right at the edge, when someone's life is actually on the line. BBecause I wanted to help people — genuinely, one patient at a time, in a system that makes it hard. CBecause I was drawn to the intensity of it — the stakes, the drama, the feeling of being fully alive. DBecause medicine is the most interesting puzzle there is — and I needed a problem worth solving. EBecause I wanted to make a difference — and also, honestly, I didn't know what else to do with my life. NEXT QUESTION → 03 What do you actually want from the people you work with? Who you want beside you under pressure is who you are. ACompetence and calm — I need people who don't fall apart when things get bad. BTrust and reliability — I want to know that when I pass something off, it's handled. CConnection — I want colleagues who become family, even if that gets complicated. DIntelligence and the willingness to be challenged — I have no interest in people who just agree with me. EFriendship — people I actually like spending twelve hours a day with, because those hours are going to happen either way. NEXT QUESTION → 04 You lose a patient you fought hard to save. How do you carry it? Every doctor who's worked a long shift has had to answer this question. AI carry it. All of it. I don't look for ways to put it down — that weight is part of doing this work honestly. BI process it and move — you have to, or the next patient suffers for the one you just lost. CI feel it deeply and lean on the people around me — I don't think you're supposed to handle that alone. DI go back over every decision — not to punish myself, but because I need to understand what I missed. EI grieve it genuinely, find some way to laugh about something unrelated, and try to be kind to myself — imperfectly. NEXT QUESTION → 05 How would your colleagues describe the way you work? Your reputation on the floor is usually more accurate than your self-image. AIntense and completely present — no small talk during a shift, but exactly who you want there. BSteady and dependable — not the flashiest in the room but never the one who drops something. CPassionate and occasionally chaotic — brilliant on the hard cases, prone to drama everywhere else. DBrilliant and difficult — right more often than anyone else, and everyone knows it, including me. EWarm and self-deprecating — not the most intimidating presence, but genuinely good at this and easy to like. NEXT QUESTION → 06 How do you feel about hospital protocol and procedure? Every institution has rules. What you do with them is a choice. AProtocol is the floor, not the ceiling — I follow it until the patient needs something it can't provide. BI respect it — the system is broken in places, but the structure is there for a reason and I work within it. CI follow it until my instincts tell me not to — and my instincts are usually right, even when they cause problems. DRules are for people who haven't thought hard enough about when to break them. EI try to follow it and mostly do — with a few memorable exceptions that still come up in meetings. NEXT QUESTION → 07 What does this job cost you personally? Nobody works in medicine without paying a price. What's yours? AEverything outside these walls — I've given this job my full attention and the rest of my life has gone around it. BMy idealism, mostly — I came in believing the system could be fixed and I've made a complicated peace with that. CStability — my personal life has been as chaotic as the OR, and that's not entirely a coincidence. DMy relationships — I am not easy to know, and the people who've tried to would probably agree. EMy sense of gravity — I use humour as a coping mechanism, which not everyone appreciates in a hospital. NEXT QUESTION → 08 At the end of a long shift, what keeps you coming back? The answer to this question is the most honest thing about you. AThe fact that it's real — that nothing else I could be doing would matter this much, right now, today. BThe patients — individual human beings who needed something and got it because I was there. CThe people I work with — I have walked through impossible things with these people and I'd do it again. DThe next unsolved case — there's always another puzzle, and I'm not done yet. EBecause despite everything — the exhaustion, the loss, the absurdity — I actually love this job. REVEAL MY HOSPITAL → Your Assignment Has Been Made You Belong In…Your answers have pointed to one fictional hospital above all others. This is the ward your instincts, your temperament, and your particular brand of dysfunction were built for. The PittYou are built for the most unsparing version of emergency medicine television has ever shown — one that puts you inside a single fifteen-hour shift and doesn't let you look away. You need your work to be real, not romanticised — meaning over drama, honesty over aesthetics. You find purpose inside the work itself, not in the chaos surrounding it. You've made peace with the fact that this job takes from you constantly, and gives back in ways that are harder to name. Pittsburgh Trauma Medical Center demands exactly that kind of person — and you would not want to be anywhere else. ERYou are the person who keeps the whole floor running — not the most brilliant in the room, but possibly the most essential. You show up, do the work, absorb the losses, and come back the next day without needing the job to be anything other than what it is. You care about patients as individual human beings, not as cases to solve or dramas to live through. You believe in the system even when it fails you — and you understand that emergency medicine is about holding the line just long enough. ER is television about endurance. You have it. Grey's AnatomyYou came to medicine with your whole self — your ambition, your emotions, your relationships, your history — and you have never quite managed to leave any of it at the door. You feel things fully and form deep attachments to the people you work with. Your personal and professional lives are permanently, chaotically entangled — and that entanglement drives both your greatest disasters and your most remarkable saves. You understand that extraordinary medicine often happens at the intersection of clinical skill and profound human connection. It's messy at Grey Sloan. You would not have it any other way. HouseYou are drawn to the problem above everything else — the symptom that doesn't fit, the diagnosis hiding underneath the obvious one. You're not primarily motivated by the patient as a person — though you are capable of caring, even if you'd deny it. You work best when the stakes are highest and the standard answer is wrong. Princeton-Plainsboro exists to house one extraordinary, impossible mind — and everyone around that mind is there because they're smart enough to keep up. The only way forward here is to think harder than everyone else in the room. That is exactly what you do. ScrubsYou understand that medicine is tragic and absurd in almost equal measure — and that the only sane response is to hold both of those things at the same time. You are warm, self-aware, and funnier than most people in your field. You use humour to get through terrible moments — and at Sacred Heart, that's not a flaw, it's a survival strategy. You lean on the people around you and let them lean back. The laughter and the grief are genuinely inseparable here. Scrubs is a show about learning to become someone worthy of the job. You are still very much in the middle of that process — which is exactly right. ↻ RETAKE THE QUIZ 'The Moonstone' (1868) Image via Tinsley Brothers Ironically, it's the tale often considered the first modern detective novel that is the least recognizable on this list — but that by no means should imply that it's the least of these mysteries. The Moonstone was published way back in 1986 by Wilkie Collins, who first released it as a serial story in Charles Dickens' own All the Year Round magazine (bet you didn't know he had his own magazine). When a priceless (and supposedly cursed) Indian jewel is stolen from under the nose of its new owner, Rachel Verinder, Sergeant Cuff is on the case. However, it's Rachel, not Cuff, who is truly the protagonist of this novel, making The Moonstone unique compared to most detective works. As one of the best crime books of all time, The Moonstone was quite influential in how future authors like Doyle and Christie would construct their fictional detectives. Still, while most of the novels on this list feature either a third-person narrator or a single character recounting the scene, Collins utilizes several. Eventually, Franklin Blake, Rachel's beloved cousin, pieces the different accounts together, allowing the mystery to come into full view. Having been adapted to the screen — and the stage by Collins himself — The Moonstone remains a classic in mystery literature that is just as suspenseful now as it was 140 years ago. 'The Maltese Falcon' (1930) Image via Alfred A. Knopf You may be more familiar with the different film adaptations of The Maltese Falcon than Dashiell Hammett's original novel, but there's no reason not to take another look at this hard-boiled piece of crime fiction. Initially a serial published in the pulpy Black Mask magazine, the tale follows San Francisco P.I. Sam Spade as he searches for the titular statuette, overturning the entire Bay Area in the process. Spade encounters not only several criminals also looking for the gold centerpiece, but a femme fatale who is not to be trifled with — though trifling is sort of his specialty. The Maltese Falcon is one of those mystery books that became the blueprint for the genre. Hammett's unconventional prose — you won't find any internal monologue here — can't help but hook you in as the mystery presents itself. Spade's encounters with Brigid O’Shaughnessy are perhaps the most memorable bits of the novel, though the entire conspiracy itself is quite a fascinating turn of events. If you're looking for detective fiction that has profoundly impacted all other crime novels (and still packs a mean punch), then The Maltese Falcon is a perfect adventure for you.
