In Enid Blyton's classic Secret Stories, mystery always leads to adventure. In Enid Blyton's very first full-length adventure novel, meet siblings Peggy, Mike and Nora. They live with their cruel uncle and aunt and long to escape, so when their friend Jack takes them to a secret, deserted island, they run away to live there. But not all is as it seems on the island, and the children soon find their adventures are only just beginning....

Someone has set fire to Mr Hick's cottage, but who could it be? Fatty, Larry, Daisy, Pip, Bets and Buster the dog have their very first case to solve. But it's not easy being detectives with policeman Mr Goon telling them to "clear orf". The Find-Outers are determined - they have to solve the mystery before Mr Goon does! In the original 1943 text, Fatty's nickname is based on the fact that his initials are F.A.T. as well as his size. All references to his size have been removed from this recording (based on the text from 2016) so that Fatty's nickname refers to his initials only.

Over on the island, they make a thrilling discovery, which leads them deep into the dungeons of Kirrin Castle on a dangerous adventure. Who - and what - will they find there?
