Fun and magic combine as usual in this new Mr. Majeika story. The pupils in Class 3 at St. Barty's School are not impressed when their head teacher imposes strict rules of behavior for Halloween. Mr. Majeika uses a little magic to make the evening memorable but nasty Hamish Bigmore tells the local press and gets the wizard-teacher the sack. School without magic seems rather boring and Mr. Majeika doesn't last long in the other jobs he tries. His long-time enemy, Wilhelmina Warlock is clearly behind all the trouble; she and the dreaded Hamish must be defeated before life can return to normal.
