Look Out, Secret Seven

The Secret Seven are Peter and his sister Janet, Jack, Colin, George, Pam and Barbara. They meet every holiday in the shed at the bottom of Peter and Janet's garden - and solve mysteries, and eat lots of delicious food. But no one can enter the shed without whispering the secret password! There are 15 Secret Seven novels, and a collection of short stories. What on earth would the Secret Seven do without Scamper the spaniel.
First he discovers an unwanted visitor - then he protects them as they spy on a thief late at night in Bramley Woods!
Each book features rarely seen bonus Blyton: extra stories, a quiz, additional artwork and insights into Blyton's life and writing process.
