Below Tumblewater is a school unlike any other, dailyschedule:dagger-throwing, advanced forgery,lockpicking,and ghostly geography

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 favorite orphan-turned-storyteller Daniel Dorey is back and on the run from sinister millionaire Caspian Prye, who kidnapped his sister. He must venture below the rain-drenched streets, where he unwittingly enrolls in a very strange school, encountering a host of weird and wonderful characters. Here kids learn the tricks they need to survive—from safecracking to double dagger-throwing, from disguises to practicing surgery on chunks of corpse.This is one school where naughtiness never goes unrewarded!Will Daniel and his schoolmates be able to put their grisly lessons into practice and rescue his sister?
