The Mystery of the Burnt Cottage Enid Blyton

Fatty, Larry, Daisy, Pep, Bets and Buster the dog turn detectives when a mysterious fire destroys a thatched cottage in Mr Hick's garden in their village.

Calling themselves the 'Five Find-Outers and Dog' they set out to solve the mystery and discover the culprit. The final solution, however, surprises the Five Find-Outers almost as much as it surprises Mr Goon the village policeman.
