Bill and his friend Anders and Eva-Lotta, the lady of both their hearts, enlivened their summer with all sorts of resourceful fun - expeditions to the town's ruined castle, a home made circus, and wonderful swashbuckling warfare with their rival gang, the Red Roses. Suddenly they find themselves involved in a real adventure - in a Stockholm police car of excaping jewel thieves!
