  1. Book 1:

    The Mysterious Affair at Styles

    Novel

    "The Mysterious Affair at Styles" (1920) is Poirot's debut -- a solid entry that introduces the fastidious Belgian detective and his "little grey cells," though it's noticeably more old-fashioned than the books that follow. Many reading guides suggest a stronger entry point instead; it runs 204 pages.

About the Hercule Poirot 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.

Frequently asked questions

Who writes the Hercule Poirot series?

Agatha Christie wrote the series; it was continued by Sophie Hannah.

Read the full authorship history →

How many Hercule Poirot books are there?

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.

What order should I read the Hercule Poirot books in?

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.

Do I need to read the Poirot books in order?

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.

Are the Sophie Hannah Poirot books worth reading?

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.

Is there a new Poirot book coming?

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.
