Geronimo Stilton Secret Agent

Who is Geronimo Stilton? That's me! I run a newspaper but my true passion is writing tales of adventure. Here is New Mouse City, the capital of Mouse Island My books are all bestsellers!! My stories are full of fun tastier than Swiss cheese and tangier than extra-sharp cheddar. They are whisker-licking good stories and that's a promise! Geronimo Stilton, Secret Agent: My sister, Thea, is the mystery loving rodent, not me! But somehow I found myself going underground to find an important missing document. Slimy Swiss cheese. I hardly knew where to start! Geronimo Stilton, Secret Agent Mouse? Maybe I could get used to that.
