Jason Bodger and the Priory Ghost

When Jason Bodger, school menace and student teacher's nightmare, visits a priory with Class 4Z, he has a most peculiar and disturbing experience. He sees a strange girl walking towards him high up on a non-existent beam. Mathilda de Chetwynde, born in a castle over 700 years ago, has dicided that Jason is "just" the person she's been waiting for - and there's not a thing Jason can do about it!
