I looked again at at the door and saw a message scrawled roughly in the mud of the wall above it, as though someone had used their whole hand to gouge it out: RIDLEY GARNET'S SCHOLE FUR VILLAINS.
Everyone's favourite orphan-turned-storyteller Daniel Dorey is back - and heads below Tumblewater on his quest to find his sister. He unwittingly enrols in a very strange school, encountering a host of weird and wonderful characters - including for example Dr Bludger, who attacks corpses with an axe to give his students the opportunity to practise stitching. Other lessons are forgery, lock-picking, knife-wielding and still-life painting (with a twist). Will Daniel and his naughty schoolmates be able to put their grisly lessons into practice and help rescue his sister?
