Harry Potter and the Order of the Phoenix
by J.K. Rowling
Lee is a Gryffindor sixth year who is also close friends with Fred and George Weasley. He announces the Quidditch games and generally participates in many of the twins' pranks. It later turns out that Lee was responsible for releasing a Niffler (an animal that sniffs out gold) into Professor Umbridge's office, thus tearing it apart.
