The Demon Headmaster Takes Over

Illustrated by Maureen Bradley

"Curiosity is the curse of the human brain!"

Suddenly, asking questions is dangerous - and finding out the answers seems impossible. What's going on?

Dinah and SPLAT investigate, and their search leads them to the Hyperbrain - a computer with more-than-human intelligence.

Who is the mysterious Controller in charge of it? He sounds horribly like the Demon Headmaster, but the Headmaster has vanished for ever ... or has he?

This is the fifth book in the Demon Headmaster series.
