When Henry fails yet again to hand in his homework for the umpteenth time, he has no idea that this will set off a chain of events which will see him forming an unlikely alliance with Moody Margaret, the infuriating girl next door, and his irritating little brother Perfect Peter, outwitting corrupt School Inspectors and toppling an evil Headmaster, winning a talent contest and facing his ultimate nemesis with no way out.
