Mouldy mozzarella! It was only a few days before Halloween when all of the pumpkins in New Mouse City disappeared. A thief was on the loose, and there was only one person I could count on to help me solve this peculiar mystery — my detective friend Hercule Poirat. But would we be able to figure out what was going on in time to save Halloween? About the Geronimo Stilton Series: Geronimo Stilton is not strong, he’s not bold, and he’s DEFINITELY not brave. Adventure?! What’s wrong with staying at home with a box of cheesy chews? Geronimo always seems to end up going on daring adventures, solving peculiar mysteries and entering tricky competitions. Will he ever get a relaxing break? The Geronimo Stilton series is perfect for 5-to-8-year-olds and reluctant readers due to its expressive typeset, fun illustrations and humorous stories.
