Agatha Christie's most famous detectives receive the Mr Men Little Miss Treatment! Miss Marple meets Mr Men and Little Miss in this new story, written and illustrated by Adam Hargreaves. Loosely inspired by Murder at the Vicarage, but with a charming and humorous twist for younger fans, this is a mystery that only an unassuming sleuth could solve! Meet Little Miss Marple - a new Little Miss who may feel more than a little familiar, particularly to Agatha Christie fans! Little Miss Marple lives in St Mary Mead, where she counts Mr Nosey and Little Miss Chatterbox among her friends and she herself 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.
