From the Winner of the Montegrappa Scholastic Prize for New Children's Writing. It's Halloween at Saint Smithen's. When the Brimwell town hall burns down, the amateur production of Macbeth is moved to the school and it's all hands on deck. But when the play is struck by a series of mysterious attacks, it's up to Poppy, her friends and her circus family to save the play and unmask the culprit.
