Which Hercule Poirot Book Has The Most Surprising Twist?

There's a particular hush I still feel whenever I think about Hercule Poirot's final case — like closing the curtains on a long-running show. The last full-length novel featuring him is 'Curtain', often printed as 'Curtain: Poirot's Last Case'. I first picked it up on a rainy afternoon after spotting a worn copy at a secondhand bookstore; there’s something strangely comforting about reading a book that was kept by its author until the end. Christie actually wrote 'Curtain' decades before it was published, keeping it sealed for publication at the end of Poirot's saga. If you haven't read it, brace yourself: it's deliberately weighty and reflective, and yes, it brings Poirot to a definite close. Fans tend to pair it with 'The Mysterious Affair at Styles' because of the symmetry — the little grey cells and the moral questions tie them together. Reading 'Curtain' feels like sitting with an old friend for a final cup of tea; it’s somber, neatly plotted, and oddly satisfying in its finality.

Picking a short Poirot to start with feels like choosing a favorite snack—small, satisfying, and easy to share. If you want the absolute quickest plunge into Agatha Christie's little grey cells, go for the short-story collections first. 'Poirot Investigates' and 'The Labours of Hercules' are both full of brisk, self-contained mysteries that you can finish in one sitting. They show Poirot's personality and Christie's clever plotting without asking for big time investment. If you prefer a single short novel, many readers recommend 'Peril at End House' or 'Hercule Poirot's Christmas' as compact, well-paced entries. Editions vary in page count, but those two tend to be shorter and keep the tension tight. I often start new friends on a short story and then hand them 'Peril at End House'—it’s punchy, has great red herrings, and gives you the classic Poirot experience without dragging. Happy sleuthing; you’ll probably want another one by the second chapter.

If you’re picturing a snowbound train with a tiny, impeccably dressed detective pacing the aisle, you’re on the right track. The book that features the Orient Express is 'Murder on the Orient Express' by Agatha Christie, first published in 1934. It drops Hercule Poirot into one of her most famous locked-room-style mysteries: a wealthy American passenger is found murdered on the train, the coach gets stuck in a blizzard, and every passenger seems to be hiding something. I still think of the slow, claustrophobic atmosphere every time I reread it — the creak of the sleeping car, the hush of the night, and Poirot calmly assembling clues while the suspicion ricochets between characters. The novel’s blend of classic deduction with a surprising moral knot at the end is what makes it stick with me. If you like puzzles with character-driven tension, grab a cup of tea and dive in. Then, if you’re in the mood, compare it with one of the film versions; they each put different flavors on Christie’s original moral tangle.

If you mean the big-screen whodunit from 1974, that movie was adapted from Agatha Christie's novel 'Murder on the Orient Express'. The book was first published in 1934 and is one of Christie's most famous plots: Hercule Poirot investigates a murder aboard the famous train, and the solution is a brilliantly structured morally tricky twist that still sparks debates in book clubs. I watched the film on a rainy afternoon with my dad years ago, and what struck me was how the movie captures the claustrophobic, snowbound tension of the book. The film keeps the central mystery and that controversial reveal, while leaning into a star-studded cast and lush production design. If you love comparing page-to-screen choices, this one’s a treat — both the novel and the 1974 film reward a second look.

I still get a little giddy when I think about how many of Hercule Poirot’s cases made it from page to screen. If you want the short map: the most famous Christie novels that were adapted as feature films include 'Murder on the Orient Express' (notably the 1974 film and the 2017 remake), 'Death on the Nile' (the 1978 film and the 2022 remake), 'Evil Under the Sun' (1982), and 'Appointment with Death' (1988). Those are the big theatrical treatments most people talk about. Beyond those, there are a few earlier and quirkier film versions: 'The Alphabet Murders' (1965) is a loose take on 'The ABC Murders', and the early sound-era film 'Black Coffee' (1931) adapts Christie’s play of the same name that features Poirot. Several other Christie Poirot novels were adapted for television or made-for-TV films — for example, 'Three Act Tragedy' was filmed in a TV movie version called 'Murder in Three Acts', and a number of other titles turned up in the long-running series 'Agatha Christie’s Poirot' starring David Suchet. If you’re curating a movie night, I’d start with the big-screen versions for spectacle ('Murder on the Orient Express' and 'Death on the Nile'), then dig into the older films and TV movies to see how different eras reimagined Poirot. Each adaptation brings its own twist, and I love spotting what they keep and what they throw away — it’s like a little detective exercise of its own.

If you want a Poirot shelf that tells a story—not just a random stack of mysteries—start with the landmarks. My first impulse was to chase the books that changed the game: 'The Mysterious Affair at Styles' (Poirot’s debut) and 'Curtain' (his final curtain call). Between those bookends I’d hunt for 'The Murder of Roger Ackroyd', 'Murder on the Orient Express', 'Death on the Nile', and 'The ABC Murders'—they’re the ones that spark the most heated conversations in book clubs and among friends, and they’re the ones people quote endlessly. Collectors’ practicalities matter too. Original Collins Crime Club hardbacks (UK) and Dodd, Mead hardbacks (US) are the holy grails if you care about first editions; dust jackets in decent shape multiply value. If chasing firsts feels overwhelming, prioritize condition: a clean dust jacket and tight binding are more enjoyable to live with than a perfect-first that’s crumbling. Short-story collections like 'Poirot Investigates' and 'The Labours of Hercules' are wonderful to own because they’re compact and give you a slew of classic puzzles, including some lesser-known gems. I also keep an eye out for signed copies, British book-club editions with nice bindings, and modern reprints that have excellent introductions or restored text. For display, facsimile dust jackets can look beautiful without destroying a rare original. And if you love the TV adaptations, getting editions with David Suchet-era tie-in covers is a fun, nostalgic touch. Ultimately, collect what brings you joy—whether that’s the famous titles, the weird oddities Christie wrote, or the plain pleasure of holding those old Collins cloth boards in your hands.

I still get a little thrill thinking about the train pulling into that snowy station—so for a first-time reader I'd point you to 'Murder on the Orient Express'. It’s the kind of book that hooks you from the setup: an enclosed space, a cast of vivid strangers, and Poirot’s meticulous mind doing its quiet, relentless work. The pacing is clean, the clues feel fair, and the moral knot at the center gives the whole thing a satisfying emotional punch beyond just the puzzle. When I first picked it up I was curled up on a rainy afternoon with a cup of tea and found myself underlining lines about motive and justice. It’s a perfect bridge between classic whodunits and something with a little more heart. If you’ve seen any film versions—there’s a 1970s classic and a recent star-studded take—you’ll get different flavors, but the book itself stands best. Start here if you want a memorable introduction to Poirot, and savor how Christie balances clue-work with character moments.

On late nights when I want a perfectly brewed cup of mystery, I usually reach for David Suchet's run of 'Agatha Christie's Poirot'. His screen Poirot feels like the closest thing to stepping into Christie's drawing room: painstaking attention to detail, the little gestures with his moustache, and adaptations that mostly respect the plots and the period. If you value faithfulness and a slow-burn unraveling, Suchet's episodes of books like 'The Murder of Roger Ackroyd' and 'Death on the Nile' (as filmed for the series) are my go-to — they let the puzzle breathe and the cast play their parts without rushing the reveal. That said, if you want cinematic spectacle, the classic film 'Murder on the Orient Express' (the older ensemble version) is a different kind of joy — lush sets, star power, and that theatrical sense of occasion. Kenneth Branagh's take on the same book throws in backstory and visual flair, which irritated purists but made for a modern blockbuster. I like rotating between Suchet for authenticity and the films for style; both satisfy different parts of me, and sometimes I watch an episode of the series and then a film just to compare how tone changes the whole mystery.
