The Secret of Cacklefur Castle

Geronimo Stilton receives a spooky invitation to Cacklefur Castle, the home of his friend Creepella von Cacklefur. Geronimo is terrified of everything—shadows, ghosts, and especially creepy castles—but he can't say no to a friend. Once he arrives at the mysterious, bone-chilling estate, he must navigate secret passageways and strange family traditions to uncover the castle's secret. It’s a "spooktacular" adventure that introduces one of the series' most eccentric recurring characters.
