The Demon Headmaster #5: The Demon Headmaster Takes Over

Who is the new Controller at the Artificial Intelligence Unit? There’s something horribly familiar about him. The unit has a computer with superhuman intelligence: the Hyperbrain, which gets its power by accessing the human brain. A computer that can go into people’s minds, and take control of them. In the wrong hands, it could spell disaster. But Dinah and her friends know that the Demon Headmaster is gone forever. Isn’t he?
