Secret Seven Mystery

Peter and Janet were having breakfast with their father and mother one lovely spring morning. Scamper, their golden spaniel, was lying as usual under the table.‘Dad,’ began Peter, but his mother frowned at him.‘Your father is reading the paper,’ she said. ‘Don’t bother him just now!’His father put down the paper and smiled. ‘Do the Secret Seven want to make themselves really useful?’ he asked. ‘Because I’ve just read something in my paper that may be right up their street!’‘Oh, Dad—what?’ cried Peter, and Janet put down her egg-spoon and looked at him expectantly.
