7. Chamber of secrets and ghosts
Chamber of secrets is a secret location within Hogwarts. The Heir of Slytherin opens it and strange things start happening in school. The chamber becomes the target of a frantic search once Ginny Weasley disappears and is finally found with the help of Harry’s knowledge of parseltongue. Everybody’s happy and the banquet is in order. But…there’s always but, isn’t there? Did it not occur to anyone in the school to ask some of gazillion of ghosts floating around through walls, floors and ceilings to search for the Chamber? Could have made for a very short book, I suppose.
