Geronimo Stilton #57: The Stinky Cheese Vacation

I, Geronimo Stilton, was finishing up work one evening when I opened a letter from Uncle Stingysnout. He needed to see me immediately! I headed straight to Penny Pincher Castle for what I thought would be a nice visit . . . but my uncle put me straight to work. Moldy mozzarella, what a terrible vacation!
