Who is Geronimo Stilton?That's me! I run a newspaper, but my true passion is writing adven-ture stories. Here in New Mouse City, the capital of Mouse Island, my books are all bestsellers! My stories are funny, fa-mouse-ly funny. They are whisker-licking-good tales, and that's a promise! I was looking for inspiration for my novel one afternoon and decided to take a bike ride through Mouse Island's countryside. Along the way, I discovered my aunt's old house was for sale. But a mysterious someone was looking to get their paws on the land first. Could I figure out who and save the house in time?
