Harry enters the Chamber of Secrets and finds Ginny, barely alive. He is awaited in the Chamber by Tom Riddle, not as a ghost but as a memory, preserved in his Diary. The diary is lying on the floor near a giant statue. Riddle has Harry's wand. He tells Harry Ginny has been writing in his diary for months and Riddle enchanted her to open the Chamber of Secrets and 'set the Serpent of Slytherin on four Mudbloods'. She finally became suspicous and tried to get rid of the diary, which Harry later found. Riddle tells the real story of fifty years ago, how he framed Hagrid and how Professor Dumbledore, then Transfiguration teacher, suspected him. For months his new target has been Harry. He uses Harry's wand and writes the words "TOM MARVOLO RIDDLE" in the air, then waving his wand the letters rearrange themselves to "I AM LORD VOLDERMORT". Riddle is the Heir of Slytherin, he is Voldemort. Riddle claims to be the greatest sorcerer in the world, Harry contradicts him saying that Dumbledore is. Along with music, Fawkes the Phoenix flies in, bringing Harry the Sorting Hat. Riddle summons the Basilisk and it enters through the statue of Salazar Slytherin. Fawkes tries to protect Harry, attacking the Serpent and blinding it. The snake's whipping tail sweeps the Sorting Hat into Harry's arms, he puts it on. A sword falls out of it. As the Basilisk lunges at him, Harry drives the sword to the hilt into the roof of the serpent's mouth, one poisonous fang sinking into his arm in the act. Fawkes cries tears onto Harry's wound. Riddle realises it and as he is about to finish Harry of with his wand, Harry takes the basilisk fang and plunges it into the diary, thereby killing Riddle. Ginny wakes up. They return to Ron and Lockhart. Lockhart's Memory Charm turns out to have backfired and has wiped out his memory. Fawkes takes them all back up to the castle and up to Professor McGonagall's office.
