Great Aunt Maria seems like a cuddly old lady, all chit-chat and lace doilies and unadulterated niceness! But when Mig and her family go for a visit, they soon learn that Aunt Maria rules Cranbury-on-Sea with a rod of sweetness that's tougher than iron and deadlier than poison. Life revolves around women's tea parties, while grey-suited men behave like zombies, and clone-like children fade into the background.
Mig is convinced that Aunt Maria must be a witch, but who will believe her? Maybe the ghost who haunts the downstairs bedroom holds the key . . . ?
