Harry Potter and the Sorcerer’s Stone Summary By Chapter | J. K. Rowling

Throughout his childhood, strange things have occurred around Harry, but he remains confused about their cause.

Chapter 3: The Letters from No One

As the summer holidays begin, Harry receives a letter addressed specifically to his “Cupboard under the Stairs.” Uncle Vernon confiscates it before Harry can read it. More identical letters arrive every day, increasing in volume until dozens pour through the mail slot.

Vernon boards up the house and moves Harry to Dudley’s second bedroom, but the letters still find him. Eventually, the Dursleys flee to a remote hotel and finally to a desolate shack on a rock in the sea, hoping to escape the relentless correspondence.

As Harry counts down the minutes to his eleventh birthday at midnight, a thunderous boom shakes the door.

Chapter 4: The Keeper of the Keys

A giant man named Rubeus Hagrid breaks down the door and introduces himself as the Keeper of Keys at Hogwarts. He is outraged to discover the Dursleys never told Harry about his parents or his magical heritage. Hagrid delivers Harry’s official acceptance letter and reveals that Harry is a wizard.

He explains that Voldemort murdered Harry’s parents and tried to kill Harry, but the killing curse rebounded, leaving Harry with a lightning-shaped scar and causing Voldemort to vanish.

Uncle Vernon tries to forbid Harry from attending, so Hagrid gives Dudley a pig’s tail and escorts Harry away. Harry begins his new life the next morning.

Chapter 5: Diagon Alley

Hagrid takes Harry to London, stopping at the Leaky Cauldron, where wizards recognize Harry and shake his hand. They enter Diagon Alley through a hidden brick wall, and Harry is amazed by the magical shops.

At Gringotts, the wizarding bank, Harry discovers his parents left him a small fortune.

Hagrid retrieves a mysterious grubby package from high-security Vault 713. Harry buys his school supplies, encountering a pale, arrogant boy in Madam Malkin’s shop.

Finally, at Ollivanders, Harry finds his perfect wand—one that shares a core with the wand that gave him his scar. Hagrid sends Harry back to the Dursleys with a train ticket for September 1st.

Chapter 6: The Journey from Platform Nine and Three-Quarters

The Dursleys drop Harry at King’s Cross Station, laughing because they know he cannot find Platform 9 ¾.

Harry encounters the Weasley family, who show him how to walk through the barrier to reach the hidden platform. On the Hogwarts Express, he shares a compartment with Ron Weasley, and they bond over magical sweets and compare their families.

They meet Hermione Granger, a bossy girl who has already memorized her textbooks, and Draco Malfoy, who tries to recruit them for Slytherin. Upon arriving at Hogwarts, the first-years cross a lake in boats and see the magnificent castle for the first time. Hagrid leads them inside.

Chapter 7: The Sorting Hat

Professor McGonagall explains the four houses—Gryffindor, Hufflepuff, Ravenclaw, and Slytherin—and how they compete for the House Cup.

The first-years are sorted by the Sorting Hat, a magical talking hat that sings about the houses. Harry is terrified of being placed in Slytherin after hearing it produced dark wizards.

When the hat considers Harry, it notes his courage and talent, ultimately placing him in Gryffindor after Harry silently begs “not Slytherin.”

Ron and Hermione are also sorted into Gryffindor. During the welcoming feast, Harry notices Professor Snape staring at him, which causes a sharp pain in his scar.

Chapter 8: The Potions Master

Harry begins his classes, finding some teachers strict and others boring. He struggles to keep up with homework while adjusting to magical life. During his first Potions lesson, Professor Snape humiliates Harry with difficult questions and seems to hate him for no apparent reason.

After losing points for Gryffindor, Harry visits Hagrid, who lives in a hut on the edge of the Forbidden Forest.

Harry finds a news clipping about a break-in at Gringotts that occurred on his birthday and suspects the thief targeted the package Hagrid took from Vault 713.

He begins to wonder if Snape is involved and why Hagrid seems secretive.

Chapter 9: The Midnight Duel

Gryffindors and Slytherins have their first flying lesson together. Neville breaks his wrist, and while Madam Hooch is away, Malfoy steals Neville’s Remembrall.

Harry flies for the first time to retrieve it, performing an incredible dive that catches Professor McGonagall’s attention.

Instead of expulsion, Harry is made Seeker for the Gryffindor Quidditch team. Malfoy challenges Harry to a midnight duel, but it’s a trap to get Harry caught by Filch.

While hiding, Harry, Ron, and Hermione discover a massive three-headed dog guarding a trapdoor in a forbidden corridor.

Chapter 10: Hallowe’en

Harry receives a brand-new Nimbus 2000 broomstick from Professor McGonagall. Oliver Wood teaches him Quidditch rules, explaining the roles of Chasers, Beaters, Keeper, and Seeker.

On Hallowe’en, Professor Quirrell announces that a troll has broken into the dungeons.

Harry and Ron realize Hermione is in the girls’ bathroom unaware of the danger.
