Revenge of the Demon Headmaster — Gillian Cross

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 . . . and when the shops have sold out, dangerous rioting starts.

Dinah and her friends are suspicious. Is it really just a trend, or is something more sinister afoot? Watching a Hunky video provides a valuable clue. Dinah and the rest of SPLAT set off in search of the real Hunky Parker. But someone is blocking them at every turn-someone who wants to keep the
identity of Hunky Parker a secret . . .

. . . Someone who plans to control the entire nation!

'Gillian Cross's novels should be prescribed for all cases of reading reluctance among eight- to ten-year-olds. The Revenge of the Demon Headmaster has the same sort of appeal as 'Famous Five' or 'Secret Seven' novels.'
