It's all very well and good saying that you know your Colin Creevey from your crumple horned snorkacks, but would you consider yourself to be a true Harry Potter expert? Even when it comes to potentially the most underrated book/movie of the lot - Harry Potter and the Chamber of Secrets?
Everyone always says that Prisoner of Azkaban is their fave, and obviously the Philosopher's Stone is the most magical, but let's not forget the Basilisk, Moaning Myrtle and Polyjuice Potion which all go down in the second book and movie.
