The Mystery of Holly Lane is an installment in Enid Blyton's Five Find-Outers and Dog series. The children—Fatty, Larry, Daisy, Pip, Bets, and their dog Buster—investigate a crime. The plot centers on a disappearance or an unusual event near the seemingly ordinary Holly Lane. The children use disguises, codes, and careful detective work, often guided by the cleverest of the group, Fatty, to solve the puzzle, usually outsmarting the bumbling local policeman, Mr. Goon.
