Are you ready for a new partnership uniting two of the most classic British brands? Hercule Poirot and Miss Marple introduced to the world of Mr. Men Little Miss in a charming and amusing re-telling of a handful of Agatha Christie’s most famous stories featuring these two characters.
The first titles publish today (23 October 2025), with a further two titles following in February 2026, set to be a delightful celebration of two much-loved and best-selling literary brands, sure to delight readers of all ages.
Little Miss Marple: Muddle at the Vicarage
Little Miss Marple lives St Mary Mead, where she counts Mr. Nosey and Little Miss Chatterbox among her friends and she herself just takes a keen interest in the goings on in the village! So, when Reverend Muddle suspects there’s been a theft at the vicarage, and there are further mysteries of the rather muddled kind, Little Miss Marple is sure she can help Inspector Nonsense and Constable Silly uncover the truth…
Mr. Poirot: Mystery on the Nile
Mr Poirot is escaping the winter gloom with a sunny cruise on the River Nile when he meets his friend Colonel Rush, who travels the world tracking down criminals. His relaxing holiday soon includes much mischief and a mystery to solve, with many Mr. Men and Little Miss suspects, including Mr. Tickle with his extraordinarily long arms! Can Mr. Poirot use his little grey cells to solve this most mischievous mystery?
To celebrate the launch of the brand-new titles, Sanrio is bringing The Great Little Mystery Book Drop to London and Manchester from 27 October 2025. The free city-wide book hunt will see hundreds of copies of the new stories hidden across the streets for families and book lovers of all ages to discover.
The partnership will form part of Agatha Christie Limited’s anniversary programme in 2026 – which marks 50 years since Agatha Christie’s death, 100 years since the publication of The Murder of Roger Ackroyd and 50 years since the publication of Sleeping Murder - with celebrations of Agatha Christie’s legacy throughout the year.
Little Miss Marple: Muddle at the Vicarage and Mr. Poirot: Mystery on the Nile publish on 23rd October 2025 in hardback for £9.99 each, for readers of all ages.
