"A Very Wicked Headmistress" by Margaret Mahy
Helen and Destiney from Room 18 bring us another crazy story from Margaret Mahy.
When the wicked Miss Taffeta—notorious cheater at cards and blackmailer, and former trapeze artist and human cannonball—opens an exclusive boarding school for rich young ladies, everything seems perfectly normal. But when strange things begin to occur at the school the students become suspicious, and they begin to wonder just who Headmistress Taffeta really is. As well as taking on the roles of all the different teachers in the school, Miss Taffeta plots to gain control of a neighbouring farmer's fortune by marrying him!
