When old Mr Jenks retires, St Barty's School advertises for a new caretaker. Unfortunately there's only one applicant - Hamish Bigmore's Uncle Wilf who is just as rude and bad-tempered as Hamish. When Mr Majeika is hurt in an accident it becomes clear that Uncle Wilf is working for the wickedest of witches, Wilhelmina Warlock It's up to Mr Majeika to work his magic and put things right again.

Class 3 are sure that something is very wrong when Mr Majeika leaves school without saying goodbye. When they find a message from him saying he's been arrested by the Silly Crime Squad, they are determined to rescue him. To do this they must outwit Hamish Bigmore and Mr Majeika's old enemy, Wilhelmina Worlock.

There's a trip down a magic river, a battle to save St Barty's from the wrecking ball, and work experience for Class Three.

Class Three has got a new computer and while exploring it, Mr Majeika manages to get the whole class trapped in the school website. Many adventures follow and Class Three meet bizarre characters before they can get out.

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 headteacher imposes strict rules of behaviour 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 behindall the trouble; she and the dreaded Hamish must be defeated before life can return to normal.

When Class Three and Mr Majeika go to the circus, it's definitely not as fun as they imagined. Everyone's a bit old, creaky and rubbish really So when Mr Majeika casts a small spell to help the performers with their circus show, it's no surprise that Billy Balance, the slack rope walker, kidnaps Mr Majeika so that Mr Majeika can magically help him everytime Things get worse whilst Mr majeika is trapped when Wilhelmina Worlock takes the opportunity to turn Class Three's classroom into a circus and the children spend all afternoon running away from lions and alligators But Mr Majeika's magic...
