It's a library slip. Take the gold coin from the spaceship fountain that's in the water, and tour the Mordred Museum. His library slip is in a stack of books and shows where the hidden "Secret of the Castle" is located. After you get the slip, go to the castle library (first floor, to the right) and look in the Non-Fiction section, lower aisle, for the McM shelf.
