The Secret Seven team includes the siblings Peter and Janet, as well as Jack, Barbara, Pam, Colin, and George. Together they are ready to solve any mystery, any time, in Enid Blyton's classic series of 15 novels. In the story, Peter runs the toy stall, but when Fred offers him a pony ride, Skipper takes over. When Peter returns, Skipper and the money have disappeared!

Besides the Secret Seven novels, Enid Blyton has written six short stories based on the characters, which are published in the Secret Seven Short Story Collection. The stories are also available in individual volumes, divided into chapters, making them ideal for young readers. They have been illustrated in full color by Tony Ross.
