Meet Malice Morbid Malign. She is from Underland, a land of sorcery, spooks and skulduggery. But, she and her family live in Topside and mischief is their business... And the business of mischief is a very serious matter! From Malignant House, Ma and Pa run the Malign Haunting Agency, tormenting Topside families and their homes. After all, it is their responsibility to maintain respectable levels of ghastly amongst the Topsiders. And as Underland representatives, the Maligns hate books, they hate bathing, and they especially HATE helping. But when grandad ghosts mysteriously start disappearing - including her own beloved grandad - Malice has no choice but to help. She partners up with her Uncle Vexatious, to solve the case of the missing grandad ghosts.
