I was just minding my business at home when I got a telephone call. It was my uncle Samuel S. Stingysnout, inviting the whole Stilton family to creepy, faraway Penny Pincher Castle for a big surprise. Moldy mozzarella I'm not much of a traveling mouse and I hate surprises but Thea, Trap and Benjamin were going, so I couldn't say no. I could tell this was going to be one super-spooky trip!
