The Mystery of the Burnt Cottage (Five Find-Outers #1)

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.
