Chamber of Secrets summary

It begins when Harry is having a miserable summer with his only remaining family, the Dursleys. During a dinner hosted by his uncle and aunt, Harry is visited by Dobby who warns Harry not to return to Hogwarts.

Harry politely ignores the warning, and Dobby wreaks havoc in the kitchen, enraging the Dursleys. The Dursleys furiously imprison Harry in his room for the rest of the summer. Fortunately, Harry’s friend Ron takes him away in a flying car, and he happily spends the rest of the summer at the Weasley house.

As classes begin, Quidditch practices begin and Draco Malfoy is Slytherin’s new seeker. In the field, he calls Hermione a “Mudblood”, insulting her Muggle heritage.

After taunting Hermione, Draco is the suspect when, on Halloween night, someone petrifies the school keeper’s cat and writes a threatening message. Before the cat is attacked, Harry hears a mysterious voice twice. He hears it first during his arrest and second during a party, moments before the cat is attacked. Everyone at school is alarmed. Upon doing some research, Harry, Ron and Hermione discover that fifty years ago a chamber was opened at Hogwarts and a student was killed.

Playing for Gryffindor, Harry wins the Quidditch match against Slytherin. During the game, an enchanted ball hits Harry, causing him to lose the bones in his arm. Dobby, a house elf, has enchanted the ball in an effort to hurt Harry and send him home.

That night, Harry sees the body of a boy who has been petrified arrive at the infirmary. Soon after, Lockhart starts a dueling club. During the first meeting, Harry terrifies his classmates by speaking Parseltongue to a snake. Harry’s ability scares others because only the Slytherin heir, who is responsible for opening the chamber, would be able to converse with the snakes.

Determined to catch the culprit, Ron, Harry and Hermione brew a potion called Polyjuice. The potion allows them to take over the bodies of Slytherins and interrogate Malfoy about the Chamber of Secrets. They discover that Malfoy is not the heir.

No more attacks occur for a while, and just before Valentine’s Day, Harry finds a diary in the broken toilet. The diary belongs to a ghost named Moaning Myrtle who haunts the girls’ bathroom. Harry writes in the journal, which he responds by writing again. Through this dialogue, he meets Tom Riddle, a boy who many years earlier had accused Hagrid of opening the Chamber of Secrets.

Hermione and a Ravenclaw girl are mysteriously petrified. Harry and Ron venture out of the castle to interrogate Hagrid. When they get to him, he tells them that by following the spiders, they can find out about the monster in the Chamber.

Several nights later, Harry and Ron sneak into the Forbidden Forest to follow the spiders. They discover that the monster that killed the girl fifty years earlier was not a spider, that the girl’s body was found in a bathroom, and that Hagrid is innocent. As they escape, Harry and Ron decide that Moaning Myrtle must have been the girl killed by the monster.

A few days later, Ron and Harry discover a piece of paper with a description of a basilisk in Hermione’s frozen hand. They deduce that the monster in the Chamber is a basilisk. Before the children can act to their knowledge, the teachers announce that Ginny Weasley has been brought to the camera.

Ron, Harry, and Lockhart slip through a secret passage in Myrtle’s bathroom into underground tunnels. When Lockhart accidentally curses himself, Ron helps him and Harry leaves them behind. Harry enters the Chamber of Secrets and comes across the immobile body of Ginny and Tom Riddle.

Tom turns out to be a younger version of Voldemort, who has been charming Ginny through his diary. Harry asks Dumbledore for help. A phoenix and a magic hat arrive. Tom summons a basilisk, but the phoenix pierces his eyes. The hat produces a sword, which Harry uses to kill the giant snake. Harry sticks a basilisk tusk into the journal, destroying Tom. Ginny wakes up.

Harry explains his adventure to Dumbledore. Lucius Malfoy breaks into the office with his house elf, Dobby, and Harry frees Dobby by tricking Lucius into giving Dobby a sock. All is well at the castle when the students go on summer vacation.

The most important theme of Harry Potter and the Chamber of Secrets book PDF is the idea of ​​destiny versus free will. Although fate is already decided, every day we have to make decisions and these choices have the ability to impact our future.

Going back to the first book, when Harry was being classified, Harry asks the Sorting Hat to put him in Gryffindor instead of Slytherin. In this second book, Harry doubts if he shouldn’t have been placed in Gryffindor, especially with all the Slytherin traits he possesses.

Due to their differences in choices, Harry and Voldemort, so similar in their childhood experiences, are drastically different. They both lost their parents at a very young age, they were both sent to live with the Muggle family, they both found their friends and stayed at Hogwarts.

However, Voldemort chose to live in constant fear of death and wanted to live forever. On the other hand, Harry lives with love and compassion and wants to help others more than himself. While many things are outside our circle of control, our choices within it are far more important than destiny.

Rowling’s emphasis on contrasting choices and striking similarities between the series’ protagonist and antagonist translate into a deeper understanding of how our personality is formed and how free will is the biggest determinant of one’s personality.
