13-IT'S SIGNED AND SEALED, STILTON!

IT'S SIGNED AND SEALED, STILTON! I left the plane. I had to find Thea. I wanted to introduce her to my new friend. I knew she would be thrilled to meet one of my fans. My sister calls me a bookworm, but I know she is proud of my success. "Thea!" I squeaked happily when I found her. "This is PENELOPE POISONFUR. She is a fan who has read all of my books!" My sister ignored me and turned to Penelope. "Well, did he sign?" she asked. P.P. still had that same strange sneer on her face. "He signed it, all right!" she laughed. "It was as easy as taking cheese niblets from a baby!" My mouth dropped open. What was she

talking about? And why did she sound so mean? Trap, Thea, and Benjamin were nodding their heads. "He signed it," they whispered to one another. Uh-oh. Something very odd was going on. What were they talking about? And why were they all staring at me? I didn't like it one bit. "Who is he?" I asked, worried. "What did he sign?" Instead of answering, Thea, Trap, and Benjamin turned toward Penelope. She pointed her paw at me. "YOU have signed it, Stilton!" she shouted at the top of her lungs.
