<P> Separated from Ron, Harry enters the Chamber of Secrets alone to find an unconscious Ginny and Tom Riddle who claims to be a memory preserved in his diary for the last fifty years . Tom Riddle shows Harry that his full name, Tom Marvolo Riddle, can be made into the anagram "I am Lord Voldemort ." Tom Riddle is in fact Voldemort's true name and it was he who opened the Chamber fifty years before, and framed Hagrid as Riddle is the true Heir of Slytherin . By possessing Ginny through his diary, Riddle has been continuing what he started fifty years before . Harry's loyalty to Dumbledore in the face of Riddle summons Dumbledore's phoenix, Fawkes, who arrives with the Sorting Hat . Fawkes blinds the basilisk, allowing Harry to remove the Sword of Godric Gryffindor from the Sorting Hat and slay the creature . Though fatally poisoned by the basilisk, Fawkes saves Harry who uses a basilisk fang to stab Riddle's diary . Both the diary and Riddle are destroyed and Ginny is restored . </P> <P> Harry, Ron, Ginny, and Lockhart return to the main castle and reunite with McGonagall, Dumbledore, and Mr. and Mrs. Weasley . Ginny, whose possession by Voldemort caused all of the petrification and troubles over the course of the year, is given a reprieve by Dumbledore . He reasons that greater wizards have been duped by Voldemort before, and takes great interest in the qualities of the diary, which Harry gives to him . Lucius Malfoy bursts in after this meeting, demanding to know why and how Dumbledore has returned to the school . He is accompanied by Dobby, revealing the family to whom he is enslaved . The house - elf also provides Harry with unspoken cues regarding the diary's ownership: While it was Tom Riddle's, it had been in the Malfoys' possession . While in Diagon Alley over the summer, Lucius, a follower of Voldemort, had slipped the diary into Ginny's cauldron to ensure the reopening of the Chamber of Secrets . Harry returns the diary, devising a scenario involving his own sock that frees Dobby from the Malfoys' employment, hence provoking an attack on Harry, only for Dobby to jump in and save him . The petrified students are cured, the end - of - year exams are cancelled (much to Hermione's chagrin), Hagrid comes back in the middle of the final feast, and Harry returns to Privet Drive in higher spirits than he last left it . </P> <P> Rowling found it difficult to finish Harry Potter and the Chamber of Secrets because she was afraid it would not live up to the expectations raised by Harry Potter and the Philosopher's Stone (Harry Potter and the Sorcerer's Stone in the US). After delivering the manuscript to Bloomsbury on schedule, she took it back for six weeks of revision . </P> <P> In early drafts of the book, the ghost Nearly Headless Nick sang a self - composed song explaining his condition and the circumstances of his unknown death . This was cut as the book's editor did not care for the poem, which has been subsequently published as an extra on J.K. Rowling's official website . The family background of Dean Thomas was removed because Rowling and her publishers considered it an "unnecessary digression", and she considered Neville Longbottom's own journey of discovery "more important to the central plot". </P>
