Geronimo Stilton Mini Mystery #3: The Mouse Hoax

Hello, mouse friends! Join me, Geronimo Stilton, in solving this whisker-licking-good mystery. Find clues along with me as you read. Together, we'll be super-squeaky investigators!

I have been invited to an exhibition of the painter Pablo Mousehasso's artwork. He was the most famouse painter on Mouse Island, so I was excited to meet him! He even offered me an exclusive interview. Little did I know that his paintings hid a secret. Would my friends and I be able to uncover it?
