DFC Library: The Boss

When Nas and Bella overhear a crook planning a daring robbery at the castle, they know just who to tell. The Boss is the smartest kid in school. Never outsmarted or outwitted, he's marshalled his class into a crime-fighting unit that could run rings round Interpol. And with the class heading for a field trip to the castle that very day, it's the perfect chance to find out what the thieves are up to - and just maybe catch them red-handed...
