There's something strange going on at school. . . There’s only a week to go before the school play when things start going wrong in rehearsals. Sets crash over, lights go on and off and the fog machine has a mind of its own. There are rumours that a headless ghost has been haunting the dressing rooms and ruining rehearsals with its ear splitting screech. Marcus and his friends must work together to solve the mystery before opening night. The show must go on, so it’s a good thing the Breakfast Club Investigators never give up! Illustrated throughout by Marta Kissi The Breakfast Club Adventures: The Headless Ghost is a funny, mystery adventure packed full of humour and heart.
