Sally Ratmousen, Editor-in-Chief of The Daily Rat and
Geronimo Stilton's biggest journalistic rival, mysteriously disappears one
afternoon on the way to her car after work. Her ace reporter, Simon Squealer,
shows up at Geronimo's door with the troubling news... and reveals that
notorious mobster Barry the Moustache is behind her disappearance. Is he telling
Geronimo the truth or is this fake news? If it's a hoax just to generate
headlines, Geronimo and Sally might be in over their whiskers as they have upset
the wrong mobster.
