'Kevin Twerp,' hissed Killer Keast, the ferocious headmaster of Shambles School, 'I want to see you in my room immediately.' Suddenly, it seemed to go cold. The light went dim. There was a gasp from the children and the teachers shivered. Kevin felt faint and his mouth went dry. Kevin Twerp's life hasn't been easy. His famous, pop-singing dad was killed in an plane crash, so his Mum has had to go out to work as a school nurse. She is now known by the unfortunate name of 'Nitty Norah the Hair Explorer'. And, as if that wasn't bad enough, looming like a dark shadow, is Killer Keast, the Headmaster. But then his mum decides to take in a lodger, and WPC Rose Button, the All-England Mud Wallowing Champion, joins the household. Now things will definitely start to happen!
