Anthony Horowitzs classic gothic page-turner is brought to life in full colour in this hilarious graphic novel adaptation.

The authorities are determined to destroy Groosham Grange, the creepy school of witchcraft and sorcery, but David Eliot and his friends have settled into life there, even if Jeffrey is now a ghost after a failed chemistry experiment. David is near the top of the leader board to win the schools coveted top prize, the Unholy Grail, but David is losing valuable points and is convinced that a new boy, Vincent King, is plotting against him. The two boys undertake a series of trials that take them to Londons British Museum to retrieve a statue belonging to Miss Pedicure, the mummified English teacher. Can David win first prize and in doing so save the school from destruction?
