For the first time, Hercule Poirot – ‘probably the greatest detective in the world’ – is celebrated in the official Agatha Christie Calendar, comprising 14 brand new cover designs from the best-selling books and (as it’s a leap year) 366 little grey cells in which to write your daily appointments!

Hercule Poirot made his debut in Agatha Christie’s very first novel, The Mysterious Affair at Styles, serialised in The Times in 1920. This 2025 wall calendar features 14 of the brand new artworks that now feature across the series of 39 Hercule Poirot paperbacks, including that very first title and many of Agatha Christie’s subsequent books: Poirot's Early Cases, The Big Four, The Mystery of the Blue Train, Cat Among the Pigeons, The Adventure of the Christmas Pudding… Glorious representations of these memorable mysteries and more can adorn your favourite wall and celebrate the never-ending charm of ‘the greatest detective in the world’.

For the first time, the 2025 Agatha Christie calendar has been produced to be environmentally friendly and fully recyclable, with no plastic packaging.
