Mr. Weasley first appears in "Harry Potter and the Chamber of Secrets", when Harry stays with the Weasley family at The Burrow during the summer before the first term of Hogwarts begins. In this book, Lucius Malfoy tries to discredit Arthur when Harry and Ron are seen flying his enchanted car and by placing Tom Riddle's diary in Ginny's cauldron so that she can open the Chamber of Secrets and take the blame for the attacks on Muggle-borns. However, Lucius fails to fulfill his objective and the diary is destroyed.
