The Demon Headmaster

When Dinah is fostered by the Hunters she thinks her biggest problem will be fitting in with her foster-brothers, Lloyd and Harvey. However, once she starts at her new school it’s clear that there’s more to worry about.

The Demon Headmaster and the Prime Ministers Brain

Everyone at school is playing the new computer game, Octopus Dare - but only Dinah is good enough to beat it. Dinah finds she can’t stop playing the game, and she forgets who she is when she looks into the whirling eyes of the Octopus. What is happening, and how is the Demon Headmaster involved? And why does he want the Prime Minister’s brain?

The Revenge of the Demon Headmaster

Hunky Parker is the new craze. His drooling, dribbling pig face is everywhere: on T-shirts and badges, and there are even horrible pig-trotter trainers and pig-swill yogurts in the shops. But it’s when the Hunky TV shows air nationally that the trouble really begins. Suddenly, people are going crazy for Hunky goods.

The Demon Headmaster Strikes Again

Dinah, Lloyd and Harvey hoped they’d seen the last of the Demon Headmaster when they moved to a new village. However, almost immediately, they can tell something’s not right about the place. There’s a loud buzzing noise coming from the biogenetic research centre, and a creeper that grows extraordinarily fast.

The Demon Headmaster Takes Over

Dinah, Lloyd and Harvey thought the Demon Headmaster was gone for good, so when they move back to their old house everything seems safe at first. Then strange things start to happen. Libraries are closing down, the internet keeps crashing, and telephones refuse to work

Facing the Demon Headmaster

Club Purple is the place to be. What makes it so fantastic is the mysterious DJ Pardoman, who keeps his face hidden behind an ever-changing electronic mask. When a competition is announced to unmask him, everyone wants to know who’s behind it. To win, entrants have to find out as much as possible about DJ Pardoman.
