Emily and James's teacher Mr. Quisling is up to something mysterious. First, there's the news clipping with an unusual note that he drops at a book event. Then Emily and James discover their teacher has been receiving encrypted messages in a series of Mark Twain books hidden through Book Scavenger. When Emily and James decipher the messages, they begin to suspect Mr. Quisling is hunting a long-rumored treasure of buried gold.

When Police Sergeant Hamish Macbeth hears reports of a haunted castle near Drim, he assumes the eerie noises and lights reported by the villagers are just local teenagers going there to smoke pot or, worse, inject themselves with drugs. Still, Hamish decides that he and his policeman, Charlie "Clumsy" Carson, will spend the night at the ruined castle to get to the bottom of the rumors once and for all. There's no sign of any ghost...but then Charlie disappears through the floor. It turns out he's fallen into the cellar. And what Hamish and Charlie find there is worse than a ghost.
