Synopsis

This book is rewritten from Book 7 of Enid Blyton’s THE SECRET SEVEN collection. The Secret Seven are Peter and his sister Janet, Jack, Barbara, Pam, Colin and George. They form the Secret Seven Society - ready to solve any mystery, any time. They have a secret password, a badge, and a secret meeting place in a garden shed.

When their usual meeting place is being painted, the Secret Seven have to find somewhere else to meet. So they choose a cave in the quarry. But it’s soon clear to the Seven that someone else is using the cave, when food, cushions and books go missing. Whoever is going there at night? It is up to the Secret Seven to find out….

Enid Blyton (1897 - 1968) is one of the world’s best-loved children’s authors. Her books have been translated into over 90 languages and are still enjoyed by children and adults all over the world.
