Barnaby Grimes is a tick-tock lad running errands in his city day and night and high-stacking around the rooftops in search of new mysteries to solve. A fantastic romp through a Dickensian-style city with a wonderful new hero in the guise of Barnaby. After collecting a strange parcel from a deserted ship in the fog of the docks and delivering it to the local schoolmaster Barnaby thinks he's earned a moment to sit on the rooftops and eat his favourite pasty. But soon he realises that all is not well at the school - but is the problem quite as he expects it? A gruesome tale of a school overrun by a terrible curse - who will survive?
