Secret Seven are a fictional group of child detectives created by Enid Blyton. They appear in one of several juvenile detective series Blyton wrote. The Secret Seven consists of Peter (the society's leader), Janet (Peter's sister), Jack, Barbara, George, Pam, Colin, and Scamper the dog. Jack's sister Susie often makes an appearance in the books; she hates the Secret Seven and delights in playing tricks designed to humiliate them, although much of this is fuelled by her almost obsessive desire to belong to the society. In many of the books, Susie is accompanied in her mischievous actions by her school friend Binkie. In one story it's mentioned that they live in the town of Peterswood.
