Something's not right. Geronimo Stilton, hardworking editor-in-chief of the Rodent's Gazette isn't himself lately. It seems that whenever there is important work for him to do, he suddenly starts sneezing or falls asleep. That's no way to run a major newspaper, especially when there is a crime spree taking place in New Mouse City. His cousin Trap gives him a coupon to a famous hypnotist, hoping that will cure him. Will Ratswami cure Geronimo, or is there something more dangerous going on?
