Harry Potter and the Chamber of Secrets

On the second book, Harry returned to Hogwarts after having passed the summer with his uncles and with Ron’s family.

Something strange happened in Hogwarts because Harry heard some voices which no one else could heard and the voice told that it was going to kill someone. All the times Harry heard the voice someone appeared petrified like the student Collin, Filch’s cat (Mrs. Norris) or Harry’s friend, Hermione. A message written with blood was also found in a wall which said that the Chamber of Secrets had been opened another time and that the sons of muggles (non magic humans) were going to be killed. Because of the message, professor McGonagall told the students the story of the Chamber of Secrets: it was built by Salazar Slytherin and there, he hid an ancient monster, a Basilisk.

On day, Ron’s sister disappeared but Harry discovered that she has been possessed by Voldemort’s school-time diary and that she had been taken to the Chamber. Harry found the entrance and opened it speaking Parseltongue. There, he got to kill the Basilisk with Godryc Gryffindor’s sword and he destroy Voldemort’s diary with poison of the Basilisk. Thanks to this, Harry got to safe Ginny’s life.
