The Phantom of the Subway (Geronimo Stilton #13)

Enter the world of Geronimo Stilton, where another laugh is always right around the corner. Each book is a fast-paced adventure with lively illustrations and a unique format kids 7-10 will love. Even my sister Thea told me a ghost was haunting New Mouse City's subway tunnels, I knew I had to get the scoop for The Rodents Gzette! So I set off with Thea, Trap and my assistant editor PinkyPick. We soon discovered that Sally Ratmousen, the editor of "The Daily Rat", was also on the trail of the mysterious ghost. But we were all in for the fright of our wee mouse lives...because the ghost turned out to be a cat!
