Harry Potter and the Chamber of Secrets In the second novel, a younger Dumbledore appears in a series of flashbacks, seen by Harry in a diary once owned by Tom Riddle, the most gifted student in Hogwarts' history - and the future Lord Voldemort. Through the diary, Harry sees Riddle's memory of Dumbledore questioning him about a series of attacks on Muggle-born students. In the present, Lucius Malfoy forces the school's other 11 governors to suspend Dumbledore as Headmaster in the wake of attacks by a basilisk in the school when the Chamber of Secrets is opened.

By the end of the book, Dumbledore's fears are realized when Harry returns from his encounter with Voldemort clutching the dead body of Cedric Diggory and when Mad-Eye Moody (being impersonated by Barty Crouch Jr, through Polyjuice Potion) takes Harry away from Dumbledore and
