哈利波特消失的密室

While home with Dursleys for the summer, Harry is visited by Dobby, a house elf, who warns him he will be in mortal danger if he returns to Hogwarts. Harry is determined to return, despite Dobby's attempts to stop him. The Dursleys have locked away Harry’s books and wand, making him a prisoner, but the Weasley brothers (Fred, George and Ron) rescue him in their dad's flying car. After a pleasant summer together, everyone heads to platform 9¾ to take the Hogwarts Express back to school. But Harry and Ron are unable to enter through the magical barrier between platforms 9 and 10. In desperation, they fly to Hogwarts in the car, crashing into the Whomping Willow, damaging Ron's wand. The semi-sentient car ejects them and their belongings and disappears into the Forbidden Forest.

Harry soon finds he is the unwanted centre of three people's attention: the vain new Defence Against the Dark Arts Professor Gilderoy Lockhart, a wizard perpetuating his own legend; admirer Colin Creevey, a young first year Gryffindor who endlessly takes Harry photo; and Ron's sister, Ginny Weasley, who has a crush on Harry. Events take a bad turn when the Chamber of Secrets is opened and a monster stalks the castle, petrifying students. According to legend, the Chamber was built by Salazar Slytherin and can only be opened by his heir (lord voldermort)to purge Hogwarts of students who are not pure-blood wizards. Many suspect Harry is the heir, especially after he inadvertently speaks Parseltongue (the language of snakes), a rare ability Harry gained after Voldemort's murderous attack when Harry was an infant. Harry, Ron, and Hermione attempt to discover the Heir of Slytherin's true identity. Using polyjuice potion brewed by Hermione, they disguise themselves as Slytherin students, Crabbe and Goyle, hoping to learn from Draco Malfoy who the heir is, although he does not know. Unfortunately, Hermione mistakenly adds cat hair instead of human to her potion and assumes a feline appearance.

The attacks increase throughout the year, petrifying students, including Hermione. Most horribly, a message written on a wall declares that a student—Ginny Weasley—has been taken into the Chamber where, "her bones will lie forever."

With Ron's help, Harry discovers the entrance to the Chamber of Secrets. They force Gilderoy Lockhart to go with them, but once inside, Ron and Lockhart are separated from Harry by falling rock. Harry makes it to the Chamber where he finds an unconscious Ginny. He also meets a young man named Tom Riddle, who claims to be a "memory." Harry learns that Ginny, under the control of Lord Voldemort, opened the Chamber. Voldemort, whose real name is Tom Riddle, imprinted his memory in an enchanted diary, to one day continue the work he begun when he reopened the Chamber fifty years ago—ridding Hogwarts of non-pureblood wizards. It was Hagrid, a Hogwarts student at the time, who was blamed for the attacks and expelled.

Tom Riddle's memory grows more powerful as it steals life from Ginny. It tries to kill Harry by setting loose the basilisk (the monster responsible for petrifying the students), but Dumbledore's phoenix, Fawkes, carries the sword of Godric Gryffindor to Harry. Fawkes blinds the basilisk, destroying its fatal gaze, and Harry slays it with the sword. He stabs the diary with a fang, and Riddle's memory is vanquished while Ginny revives a near death state. She fully recovers, as do the petrified students.
