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.
Peter and Janet are the only witnesses when a car is stolen. They saw the thieves, and now all the Secret Seven are involved. But when they realise they are on the trail of a dangerous gang, the Seven don't feel quite so brave. This time, they might have taken on too much.
