Harry Potter and the Chamber of Secrets Cheats (Playstation/PSone)

Complete all of the Wizard duels (in Hogwarts), then go to the start of the duel hall, but turn through a second hall and hit the wall with Flipendo. Then climb up about 3 of the steps that unfold. Use the vedimilleous on the see-through planks. Now jump on all of the planks until you get to a door, go through and you will find a book on a table.
