The Mystery of the Burnt Cottage is the first book in Enid Blyton's Five Find-Outers and Dog series. The series begins when the children—Fatty, Larry, Daisy, Pip, and Bets—witness a cottage fire and decide to investigate the suspicious circumstances. This book establishes the group's formation and introduces the central dynamic of the children solving crimes faster than the furious local policeman, Mr. Goon. It sets the standard for their organized, puzzle-solving adventures.
