There's a new computer game at school and the chance to enter the Junior Computer Brain of the Year competition is sending ripples of excitement through the pupils. Dinah is a whizz at the game and soon finds herself in the competition final. But it takes a while to realize that it's all just part of the Demon Headmaster's latest plan . . . Dinah is being used to access the computer of the Prime Minster.

Great fun and just a little bit frightening, Gillian Cross's Demon Headmaster books still hold readers under their hypnotic spell. Fast-paced and full of adventure, they're impossible to resist!

Gillian Cross is one of the best children's novelists today and her stories of the Demon Headmaster are both fun and quite frightening.

Highly recommended.

This is a fast-moving story for younger children, but thought-provoking for older ones.
