The Hercule Poirot series by Agatha Christie has 41 books and is best read in publication order, starting with The Mysterious Affair at Styles (1920).
Start here: The Mysterious Affair at Styles (1920) — then read straight through in publication order.
The order the books were released — the default way to read the series.
Hercule Poirot is the fastidious, egg-headed Belgian detective who solves murders with his "little grey cells" rather than legwork — a private inquiry agent, former Belgian policeman, and refugee of the First World War who settles in England and becomes the most famous fictional detective after Sherlock Holmes. Agatha Christie built the character across 33 novels and dozens of short stories between 1920 and 1975, perfecting the fair-play puzzle mystery: a closed circle of suspects, a country house or a locked train carriage, a scattering of clues planted in plain sight, and a final drawing-room scene where Poirot walks the reader back through every lie. The appeal is the puzzle itself — Christie plays scrupulously fair, so an attentive reader can, in theory, beat Poirot to the solution, and the fun is in trying and almost always failing.
The best-known entries (Murder on the Orient Express, Death on the Nile, The A.B.C. Murders) rank among the most influential mysteries ever written, twice adapted for film by Kenneth Branagh and dramatised in full by David Suchet's long-running ITV series. Christie also wrote Poirot's swansong, Curtain, decades before its 1975 publication, sealing off the character's story on her own terms. Since 2014, novelist Sophie Hannah has written authorised continuation novels set in Poirot's original era, for readers who have finished Christie's run and want more without it being pastiche. This is the series for anyone who wants the genre's gold standard: elegant misdirection, a satisfying reveal, and a detective whose vanity is as entertaining as his brilliance.
Agatha Christie wrote 33 Poirot novels between 1920 and 1975, plus short-story collections including Poirot Investigates and The Labours of Hercules. Since 2014, Sophie Hannah has added six authorised continuation novels, for 39 novels (41 entries counting the two collections) tracked here.
Publication order is the default and the novels are almost entirely standalone. If you'd rather skip the more dated debut, start with The Murder of Roger Ackroyd or Murder on the Orient Express instead of The Mysterious Affair at Styles.
No. Nearly every novel is a self-contained case. The one exception is Curtain, explicitly written as Poirot's final case — save it for last.
They're optional. Sophie Hannah's authorised continuations (starting with The Monogram Murders, 2014) are set in Poirot's original 1920s–30s era and aim for the classic puzzle style, but they're a modern writer's take rather than Christie's own work — best treated as a bonus after finishing the originals.
The most recent is Sophie Hannah's The Last Death of the Year (November 2025). No new Poirot novel has been announced as of mid-2026.
