The Seven and their Rivals 5

The Secret Seven have their last meeting before the Christmas holidays, as adventures don't usually happen during term time.

But Jack's younger sister, Susie, who has formed a club with four other friends to imitate the Secret Seven, sets a trap for her brother. Jack and Peter go to Tigger's Barn - the ruined house that serves as a shelter for tramps - at night and get a terrible fright when they overhear some individuals having a suspicious conversation.

Fear turns into excitement and the friends decide to call an urgent meeting; they have a mystery to unravel and a new adventure to experience!
