Chapter 1 Summary – Harry Potter and the Prisoner of Azkaban – Messenger Owls

Harry spends the summer with the Dursleys, secretly studying magic at night while enduring his relatives’ hostility. He works in hiding on an essay about medieval witches, afraid any noise will give him away and lead to punishment. Although he misses Ron and Hermione, a failed attempt by Ron to call him causes a fierce argument with Uncle Vernon. Despite restrictions, Harry is allowed to let Hedwig, his owl, fly at night, and she returns accompanied by two others carrying birthday gifts and letters from his friends. Ron sends a Sneakoscope and news about his vacation in Egypt; Hermione sends a broomstick kit. Hagrid sends him a monster book. Harry receives his Hogwarts letter, which includes a permission slip to visit Hogsmeade, requiring his uncle’s signature. For the first time in years, Harry feels truly happy on his birthday, surrounded by his friends’ affection.

Chapter 2 Summary – Harry Potter and the Prisoner of Azkaban – Aunt Marge’s Mistake

Aunt Marge visits, bringing a week of humiliation and mistreatment for Harry. Before picking her up, Uncle Vernon demands Harry behave normally, hide that he’s a wizard, and maintain the lie that he attends the fictional St. Brutus’s school. Interested in getting permission to visit Hogsmeade, Harry agrees under the condition that Vernon sign the slip. During the visit, Marge constantly insults him, reminding him of his origins and denigrating his parents. Harry endures it silently, hoping to get the signature, but on the last night, Marge calls Harry’s parents failures. Overcome with rage, Harry loses control and causes her to inflate like a balloon. Taking advantage of the chaos, he packs his things, threatens Uncle Vernon with his wand, and leaves the house at night. For the first time, he openly stands up to his family, determined to walk away without knowing what lies ahead.

Chapter 3 Summary – Harry Potter and the Prisoner of Azkaban – The Knight Bus

While fleeing Privet Drive, Harry is alone, aimless, and frightened of the consequences of using magic outside school. As he weighs his options, he senses someone watching him and sees a dark figure with shining eyes. Lighting his wand, he stumbles and accidentally summons the Knight Bus, a magical transport for stranded witches and wizards. Using the false name Neville Longbottom, Harry hears about Sirius Black for the first time—a dangerous fugitive from Azkaban wanted by both wizards and Muggles. During the ride to London, Stan Shunpike tells him Black was a Voldemort supporter who killed thirteen people with a single curse. Upon arriving at the Leaky Cauldron, Harry is intercepted by Cornelius Fudge, the Minister of Magic, who surprisingly doesn’t punish him. Instead, Fudge gives him a room at the inn, forbids him from entering the Muggle world, and assures him that Aunt Marge has been deflated and remembers nothing.

Chapter 4 Summary – Harry Potter and the Prisoner of Azkaban – Two Weeks in Diagon Alley

Harry enjoys his freedom in Diagon Alley, spending days exploring magical shops, doing homework outdoors, and eating ice cream with Florean Fortescue’s help. Fascinated by the new Firebolt broom, he resists buying it. He purchases school books, including The Monster Book of Monsters, which matches Hagrid’s gift, and a divination manual. He grows uneasy upon seeing a picture of a large black dog in a book—similar to one he saw on Magnolia Street. Eventually, he meets up with Ron and Hermione, who arrive with their families. Ron shows off his new wand, and Hermione introduces her cat, Crookshanks, who attacks Ron’s rat, Scabbers. During dinner, Mr. Weasley mentions the fugitive Sirius Black, and later, Harry overhears Ron’s parents arguing that Black is after him. Though disturbed, Harry is not afraid—he trusts Dumbledore and is determined to protect himself.

Chapter 5 Summary – Harry Potter and the Prisoner of Azkaban – The Dementor on the Train

Harry and the Weasleys depart from the Leaky Cauldron toward Hogwarts. On the train, Harry tries to tell Ron about Sirius Black, but constant compartment changes and the presence of a new professor, the mysterious R. J. Lupin, interrupt the conversation. During the trip, the train suddenly stops, and a Dementor—a dark creature from Azkaban—boards the carriage. Harry faints upon sensing its presence, experiencing cold terror and distant screams. Lupin steps in and repels the Dementor with a protective charm. Although Harry recovers, he’s puzzled by his strong reaction. Upon arriving at the castle, students see more Dementors guarding the entrances. At the welcome feast, Dumbledore introduces the new professors—Lupin and Hagrid, who now teaches Care of Magical Creatures. The mood is tense, but returning to Hogwarts comforts Harry, as he feels he’s truly home.

Chapter 6 Summary – Harry Potter and the Prisoner of Azkaban – Tea Leaves and Hippogriff Claws

On the first day of classes, Harry becomes the target of Malfoy’s mockery after fainting in front of the Dementor. Hermione receives an impossible schedule with multiple classes at the same time, raising suspicions. In Divination, the eccentric Professor Trelawney predicts a dark fate for Harry after seeing a Grim in his tea leaves—a death omen. Hermione dismisses the prediction, but Ron is alarmed, recalling that his uncle died after seeing one. In Care of Magical Creatures, Hagrid introduces the class to hippogriffs. Harry successfully approaches and rides Buckbeak, earning admiration from his peers. However, Malfoy deliberately provokes the creature and is injured, accusing Hagrid of negligence. Worried about the impact on his new job, Harry, Ron, and Hermione visit Hagrid that night. They find him devastated, but they comfort him and promise their support. Their loyalty strengthens their bond and reflects their stand against injustice.

Chapter 7 Summary – Harry Potter and the Prisoner of Azkaban – The Boggart in the Wardrobe

Malfoy returns to class pretending to be gravely injured, using the opportunity to pester Harry and Ron during Potions. As always, Snape favors Malfoy, enraging the Gryffindors. While preparing a shrinking potion, Hermione discreetly helps Neville, who is mocked by Snape. At the end, Snape unfairly takes points from Gryffindor, despite Neville’s potion being correct. Later, in Defense Against the Dark Arts, Lupin surprises them with a practical lesson. He introduces a boggart—a creature that takes the shape of one’s worst fear. Using humor as a defense, Lupin guides Neville to transform the boggart into a comical version of Snape in his grandmother’s clothes, triggering laughter all around. The class continues with several students confronting their fears, and Harry notices that Lupin prevents him from taking a turn. Intrigued, he suspects that Lupin knows Harry fears not Voldemort, but the Dementors.

Chapter 8 Summary – Harry Potter and the Prisoner of Azkaban – The Fat Lady’s Escape

Defense Against the Dark Arts lessons with Professor Lupin delight everyone except Draco Malfoy, who mocks his appearance. Harry enjoys learning about dangerous creatures like Red Caps and Kappas, unlike in Potions, where Snape is more vindictive than ever—especially toward Neville after the boggart incident. In Divination, Professor Trelawney persists in predicting Harry’s death, which Parvati and Lavender take seriously. Hagrid, having lost confidence, makes his classes dull. Quidditch lifts Harry’s spirits, especially thanks to Oliver Wood’s motivating practices. However, his excitement fades when he learns he can’t go to Hogsmeade due to a lack of permission. Tensions rise with Ron and Hermione’s quarrel over Crookshanks and Scabbers, and a mysterious attack on the Fat Lady’s portrait reveals that someone dangerous—Sirius Black—tried to enter the Gryffindor Tower.

Chapter 9 Summary – Harry Potter and the Prisoner of Azkaban – The Defeat

After the Fat Lady’s portrait is attacked, Dumbledore orders all students to sleep in the Great Hall. The atmosphere is tense, filled with rumors about how Sirius Black managed to get into the castle. Professors, led by Dumbledore, conduct a thorough search but find no trace of him. Sir Cadogan is appointed the new guardian of the Gryffindor Tower, though his eccentric behavior makes him unpopular. Meanwhile, McGonagall bans Harry from Quidditch practices but later allows him to resume under supervision. Slytherin postpones the match, claiming Malfoy is still injured, so Gryffindor faces Hufflepuff and their skilled Seeker, Cedric Diggory. On match day, a storm darkens the sky. Already weakened by the cold, Harry is attacked by multiple Dementors, falls off his broom, and loses the match. His Nimbus 2000 is destroyed after crashing into the Whomping Willow, leaving Harry devastated.

Chapter 10 Summary – Harry Potter and the Prisoner of Azkaban – The Marauder’s Map

While recovering in the hospital wing, Harry feels humiliated by his reaction to the Dementors and disturbed by the recurring memory of his mother’s last screams. Although his friends try to cheer him up, he remains affected by the Grim—the death omen that keeps appearing to him. Returning to class, Lupin excuses Harry from Snape’s assignment and promises to teach him how to defend himself from Dementors. In secret, Fred and George give Harry the Marauder’s Map, which reveals all the castle’s secret passages, allowing him to sneak into Hogsmeade. At Honeydukes, he reunites with Ron and Hermione, and they visit the Three Broomsticks. There, hidden, he overhears a revealing conversation between Fudge and several professors: Sirius Black was James Potter’s best friend, Harry’s godfather, and the Secret-Keeper of the Potters’ hiding place. He was the one who betrayed them—and also the one responsible for the death of their friend, Peter Pettigrew.

Chapter 11 Summary – Harry Potter and the Prisoner of Azkaban – The Firebolt

After discovering at the Three Broomsticks that Sirius Black was responsible for his parents' deaths, Harry returns to Hogwarts shaken, consumed by a mix of anger and confusion. Amid the Christmas chaos in the common room, Harry isolates himself in the dormitory and examines a photo from his parents’ wedding, where a young, smiling Black appears as best man. Unable to sleep, he becomes obsessed with thoughts of revenge. The next day, Ron and Hermione try to dissuade him from acting impulsively, but Harry can’t accept that Black remains free. They visit Hagrid and learn that Buckbeak will be put on trial after Lucius Malfoy’s complaint. A devastated Hagrid fears losing the creature and returning to Azkaban. Harry and his friends promise to help him. On Christmas morning, Harry receives a mysterious broomstick: a Firebolt. Hermione, suspecting danger, reports it, and McGonagall confiscates it for magical inspection.

Chapter 12 Summary – Harry Potter and the Prisoner of Azkaban – The Patronus

Affected by the loss of the Firebolt, Harry begins private lessons with Professor Lupin to learn how to defend against Dementors. Lupin teaches him the Patronus Charm, an advanced spell requiring focus on a happy memory. In early attempts, Harry hears his mother’s screams and his father’s voice facing Voldemort, collapsing before the boggart in Dementor form. Still, he persists and manages to produce a faint silver outline. In a particularly hard lesson, he remains standing as the Patronus shields him. Tension grows between Harry, Ron, and Hermione over the broom and Scabbers’ disappearance. Harry learns that Lupin was friends with his father and also knew Sirius Black, but avoids the topic. In the end, McGonagall returns the broom after confirming it’s not cursed, cheering Harry and prompting reconciliation with Hermione, who had only wanted to protect him.

Chapter 13 Summary – Harry Potter and the Prisoner of Azkaban – Gryffindor vs. Ravenclaw

Ron and Hermione’s rift deepens after Scabbers’ apparent death, with Crookshanks’ fur found in a bloodied sheet. Harry tries to keep peace but fails, while the Gryffindor team prepares for the crucial match against Ravenclaw. During practice, Harry impresses everyone with the Firebolt’s speed and control. In the match, Cho Chang, the opposing Seeker, keeps up with him, but Harry’s broom gives him the edge. Despite a brief distraction from fake Dementors—Malfoy, Crabbe, Goyle, and Flint in disguise—Harry casts a powerful Patronus and catches the Snitch, securing victory for Gryffindor. Celebrations erupt in the common room with sweets, butterbeer, and excitement. Only Hermione remains apart, absorbed in her studies. That night, Ron wakes up screaming: he claims Sirius Black was in their dormitory, armed with a knife, shocking the entire Gryffindor Tower.

Chapter 14 Summary – Harry Potter and the Prisoner of Azkaban – Snape’s Grudge

After Sirius Black’s intrusion, the castle adopts stricter security measures. Ron becomes the center of attention, recounting how he saw Black holding a knife in their room. Meanwhile, Neville is harshly punished for losing the password, even receiving a howler from his grandmother. Harry and Ron visit Hagrid, who reminds them that Hermione has been helping him with Buckbeak’s defense. Hagrid scolds them for ignoring Hermione and leaving her alone during tough times. Tension between Ron and Hermione persists, especially due to the conflict over Crookshanks. Harry, breaking rules, sneaks into Hogsmeade under his Invisibility Cloak but is spotted by Malfoy. Snape interrogates him and discovers the Marauder’s Map, but Lupin intervenes to prevent further consequences. Hermione finally tells them that Buckbeak has lost the trial and is sentenced to execution.

Chapter 15 Summary – Harry Potter and the Prisoner of Azkaban – The Quidditch Final

Hermione announces Buckbeak’s execution, and Ron, moved, pledges to help with the appeal. Exams and pressure mount as Hermione shows signs of extreme exhaustion. In Care of Magical Creatures, Hagrid is distraught and forgets key details due to stress over the trial. Overwhelmed, Hermione slaps Malfoy and storms out of Divination after arguing with Trelawney. As exams and the Quidditch final approach, tension builds between Gryffindor and Slytherin. On match day, Harry is cheered as he enters the pitch, and the Firebolt helps him dodge several dirty tricks from the Slytherin team. Despite Malfoy’s sabotage attempts, Harry catches the Snitch after a spectacular play. Gryffindor wins the match and the Quidditch Cup. Amid the general euphoria, everyone celebrates, and Harry feels he has finally achieved something truly glorious.

Chapter 16 Summary – Harry Potter and the Prisoner of Azkaban – Professor Trelawney’s Prediction

The excitement from the Quidditch win fades as exams and Buckbeak’s execution draw near. Hermione, stressed, struggles to keep up with her overwhelming schedule while Ron and Harry help with the hippogriff’s defense. They soon receive word that the appeal has been denied and the execution will take place that very evening. During the Divination final, Harry hears a sinister prophecy from Professor Trelawney, who seems possessed: the servant of the Dark Lord will return to him that night. When he tells Ron and Hermione, they discover Buckbeak has lost his case and will be executed at sunset. Using the Invisibility Cloak, they sneak to Hagrid’s hut, where they unexpectedly find Scabbers alive. As they prepare to leave, they hear the final blow of the axe behind Hagrid’s home. All seems lost. The fate of the hippogriff and the eerie prophecy cast a dark shadow over what lies ahead.

Chapter 17 Summary – Harry Potter and the Prisoner of Azkaban – The Dog, the Cat, and the Rat

Harry, Ron, and Hermione, hidden under the Invisibility Cloak, return from Hagrid’s hut when Scabbers starts struggling in Ron’s pocket. Crookshanks appears and the rat escapes, prompting a frantic chase in the dark. Ron runs after them but is suddenly dragged away by a large black dog into the Whomping Willow. Harry and Hermione try to follow, but the tree attacks them. Crookshanks disables the trunk’s secret mechanism, allowing them access to a tunnel that leads to the Shrieking Shack. There they find Ron injured, insisting that the dog is actually an Animagus—Sirius Black. Black disarms them and confronts Harry, claiming to have been James’s friend. Driven by rage, Harry tries to attack him, but Hermione and Ron stop him. At that moment, Professor Lupin arrives and, shockingly, embraces Black—leaving everyone stunned.

Chapter 18 Summary – Harry Potter and the Prisoner of Azkaban – Moony, Wormtail, Padfoot, and Prongs

Ron, Harry, and Hermione struggle to believe the story Lupin and Sirius share: Peter Pettigrew is alive and has been disguised as Scabbers the rat for twelve years. Lupin reveals that he, James, Sirius, and Peter were friends and that three of them became Animagi to accompany him during his werewolf transformations. Together, they created the Marauder’s Map with their nicknames: Moony, Wormtail, Padfoot, and Prongs. Lupin explains Sirius was falsely accused, and Peter faked his death to escape. Hermione deduces Lupin is a werewolf, which he confirms. Snape bursts in, ready to arrest them all, but Harry, Ron, and Hermione disarm him. Black shows a photo in which he recognized Pettigrew on Ron’s shoulder. Finally, with a spell, they force Scabbers to transform into his human form: a nervous, frightened man who cannot deny his identity as Peter Pettigrew.

Chapter 19 Summary – Harry Potter and the Prisoner of Azkaban – The Servant of Lord Voldemort

Cornered, Peter Pettigrew tries to convince Lupin and Sirius of his innocence, but his pleas fall flat. Black accuses him of betraying the Potters and escaping after killing innocents. Lupin and Black explain that Peter lived as a pet to hide from Voldemort’s remaining supporters. Though filled with fury, Harry stops them from killing him and insists on sending him to Azkaban. Pettigrew tries to manipulate Ron and Hermione, but both reject him. Lupin chains him to Ron and uses a spell to splint the boy’s broken leg. Snape, still unconscious, floats behind them as they begin their return to the castle. Despite the horrifying revelations, Harry chooses compassion, remembering his parents wouldn’t have wanted vengeance. Black and Lupin honor his decision, and Pettigrew is bound and defeated, with no way to escape.

Chapter 20 Summary – Harry Potter and the Prisoner of Azkaban – The Dementor’s Kiss

The group exits the Shrieking Shack through the tunnel with Pettigrew chained and Snape still unconscious. Along the way, Sirius reveals to Harry that he is his godfather and proposes they live together once his innocence is proven. Harry, overjoyed, agrees. But outside, the full moon rises, and Lupin, having not taken his potion, transforms into a werewolf and loses control. Sirius, turning into a dog, battles him to protect the others. Pettigrew takes advantage of the chaos, seizes a wand, attacks Ron and Crookshanks, and escapes in rat form. Sirius is seriously injured in the fight with Lupin and flees toward the lake. Harry and Hermione follow but are surrounded by hundreds of Dementors. Harry tries to protect them with a Patronus, but it’s not strong enough. Near death, he sees a luminous figure gallop across the lake, repelling the Dementors. Then, he collapses.

Chapter 21 Summary – Harry Potter and the Prisoner of Azkaban – Hermione’s Secret

While Harry lies in the hospital wing, he hears Snape trying to convince Minister Fudge that Sirius manipulated the students. However, Hermione, now awake, silently points Harry to what’s happening. When Dumbledore enters, he clears the room to speak privately with Harry and Hermione. He explains that he can’t do anything to save Sirius without evidence, but hints at a mysterious solution: “three turns should do it.” Hermione then reveals to Harry the Time-Turner she used all year to attend simultaneous classes. Together, they travel three hours into the past, just before Buckbeak’s execution. They hide and retrace their steps in secret. Cleverly and unseen, they free Buckbeak moments before the execution squad arrives at Hagrid’s hut. The hippogriff escapes, baffling the officials. Then, they wait in the forest for the right moment to rescue Sirius as well.

Chapter 22 Summary – Harry Potter and the Prisoner of Azkaban – More Messenger Owls

Harry and Hermione return to the hospital wing seconds before Dumbledore closes the door, ensuring the mission’s success. Snape, furious upon discovering Sirius’s escape, accuses the students, but Madam Pomfrey’s flawless alibi stops him. The next day, Harry visits Lupin, who is packing after resigning due to Snape publicly revealing he is a werewolf. Though Harry pleads with him to stay, Lupin departs, but not before returning the Invisibility Cloak and Marauder’s Map. Dumbledore comforts Harry, saying that saving Pettigrew will have unforeseen consequences and that his father lives on in him. At the end of the term, no one knows the truth about Sirius and Buckbeak’s escape. Harry, Ron, and Hermione celebrate their achievements, and on the train, they receive an owl with a letter from Sirius, confirming he sent the Firebolt. He also authorizes Harry to visit Hogsmeade and gifts Ron a small owl.

Conclusion – Harry Potter and the Prisoner of Azkaban

As the last page of Harry Potter and the Prisoner of Azkaban closes, one thing is clear: this isn't just another chapter in the series — it’s a turning point in Harry’s emotional journey. In this book summary by chapter, we’ve witnessed a world where the innocent are imprisoned, the guilty hide in plain sight, and the Ministry doesn’t always get it right. The idea of justice is challenged, and trust becomes a luxury that few can afford.

The Patronus Charm emerges as a metaphor for inner strength, the truth about Scabbers shakes long-held beliefs, and time itself becomes a tool for rewriting fate. In this installment, the characters gain new depth, their loyalties are tested, and their pasts begin to bleed into the present — all framed by the heart-wrenching story of Sirius Black, the godfather who was never guilty to begin with.

But the journey is far from over. What follows is not just darker — it’s more dangerous, more political, more epic in scale. And if you’re ready for the next stage, continue here: Harry Potter and the Goblet of Fire – Book Summary by Chapter ➤

FAQs – Chapter by Chapter Summary – Harry Potter and the Prisoner of Azkaban

What do Dementors do in Prisoner of Azkaban, and why do they overwhelm Harry so badly?

Dementors—Azkaban’s wardens—drain warmth, hope, and happy memories. On the Hogwarts Express, their proximity forces Harry to relive his parents’ final moments, triggering a blackout and establishing the need for the Patronus Charm as the book’s emotional core. As symbols, they externalize trauma, depression, and paralyzing fear; as plot devices, they darken the school year and raise the stakes across “Harry Potter 3.” Learning the Patronus isn’t just spellwork—it’s Harry reclaiming memory and agency against predatory despair.

Is Sirius Black actually guilty? How does the Shrieking Shack twist clear his name?

The truth detonates in the Shrieking Shack: Lupin and Sirius expose Peter Pettigrew as the real traitor who faked his death and hid as Ron’s rat, Scabbers. Forced back into human form, Pettigrew’s lies collapse, revealing that Sirius was framed and the Ministry misled. This twist reframes the entire hunt, reinterprets the Marauder’s Map, and pivots the story from revenge to justice. By sparing Pettigrew, Harry rejects the cycle of violence and sets future consequences in motion—even as Sirius must flee on Buckbeak, still a fugitive despite his innocence.

How does Hermione’s Time-Turner work, and why do “three turns” rewrite the ending?

The Time-Turner lets Hermione step back hours to attend overlapping classes, but in the finale it becomes a surgical tool: “three turns” place her and Harry behind their past selves. They free Buckbeak just before the execution party arrives and later rescue Sirius from his cell, preventing the Dementor’s Kiss without breaking causality. The device resolves Hagrid’s legal tragedy and restores Sirius’s chance at freedom, while embodying the book’s central idea: time—when handled with empathy and restraint—can heal, correct, and give characters power over their own narrative.

What do “Moony, Wormtail, Padfoot, and Prongs” mean, and how do they tie into the Marauder’s Map?

They’re the nicknames of Remus Lupin (werewolf), Peter Pettigrew (rat), Sirius Black (dog), and James Potter (stag)—friends who became Animagi to accompany Lupin during full moons. Together they engineered the Marauder’s Map, a rebellious masterpiece that charts Hogwarts and tracks every person inside. The quartet’s history bridges Harry’s present to his father’s past; it also explains why the Map “knows” secret passages and why Harry’s Patronus takes a stag form—inheritance, loyalty, and youthful mischief turned bittersweet by betrayal.

Why does the Firebolt matter beyond Quidditch—what does it mean for Harry’s arc?

The Firebolt is momentum made tangible. After the Nimbus 2000’s destruction and a season shadowed by Dementors, its anonymous arrival (later revealed to be from Sirius) restores confidence and possibility. Yes, suspicion strains Harry and Hermione, but the broom’s eventual clearance marks a maturity beat: thrill tempered by caution. On the pitch, its speed powers the Ravenclaw win and the Cup-clinching triumph over Slytherin; off it, the Firebolt becomes a thread to family, signaling that Harry’s life can hold both exhilaration and care in the same breath.
