Mr. Helliwell

Mr Helliwell was the antagonist in Anthony Horowitz's novel Return to Groosham Grange and he was one of the great Voodoo magicians. He was infamous on Haiti to the point where the postman wouldn't deliver mail. Mr Helliwell eventually was hired by the board of Groosham Grange, a school for young wizards and witches.

Mr Helliwell hated the school when he first got there but had to pretend he liked it. For in reality he had been converted by the puritannical Bishop of Bletchley, who sought to vanquish all supernatural creatures. And the staff of Groosham Grange included a vampire (John Kilgraw) two black magicians with the same body (Mr Fitch and Mr Teagle) a black witch who had lived for four centuries (Miss Pedicure) and a ghost named Mr Creer, as well as a werewolf named Mr LeLoup. Mr Helliwell plotted against the staff and the school and finally found the answer: To destroy the school he had to take the prize source of all magic, the Unholy Grail, and take it into the shadow of Canterbury Cathedral. He first needed a way of getting the Grail off the school without any suspicions. Mr Helliwell found the answer in David Eliot, whose parents lived near Canterbury, so he gave the Grail to them and they took it off the island of Groosham Grange and destroyed much of Suffolk. Mr Helliwell came to get the Grail and went to Canterbury.

Mr Helliwell had chained up David and Vincent and Jill, who were two other of David's classmates, but he didn't count on them escaping from the ruins of the school and David launching himself after Mr Helliwell with the last of the schhool's magic on a broomstick. David made it to Canterbury but crashed as the magic was almost gone. David broke some ribs and his leg, but he confronted Mr Helliwell when he had revealed himself. Helliwell revealed how he had been seduced by the Church and how he wanted to destroy the supernatural. However, David launched his broomstick at Helliwell. Helliwell ducked but saw the cathedral shadow was no longer in place because David had sliced off the tower with his broomstick. So the school wasn't destroyed. Mr Helliwell could only snarl before the tower came crashing down on his head, killing him.
