Harry Potter and the Prisoner of Azkaban (novel)

""I don't go looking for trouble. Trouble usually finds me.""

- Harry

The third Harry Potter book. Published in 1999. Often considered the point at which the series Grew The Beard.

Sirius Black has escaped from Azkaban, the wizarding prison. In response, the Ministry of Magic sends Dementors, a race of dreadful creatures which either wear or are made of Black Cloaks, to guard Hogwarts and their Emotion Eating powers seem to affect Harry especially. Remus Lupin, meanwhile, makes his first appearance, taking on the dreaded Defense Against the Dark Arts post.

The book's popularity may be partially due to the introductions of Sirius and Lupin, considered by some fans to be two of the coolest characters in the series. It also marks the point where the books started to become more serialized with each ending setting up the next one. It also has, quite possibly, the most complicated plot of the entire series, drawing in characters and events from all over the place; the Prisoner of Azkaban is obviously important, but the way he is important zig-zags several times over the course of the novel, and the same thing happens to a bunch of other characters. The end result is that, by the end of the novel, the story's landscape has irrevocably changed... and readers know that things are going to get really interesting from now on.

As a side note, this is the only volume in the series where Lord Voldemort doesn't make an appearance.

Tropes exclusive to this book or at least especially prominent in it:
"hey children did you enjoy this wonderful children's book full of wonderful awesome things for children well let me WRITE A BOOK BUILT ENTIRELY ON THE FEAR THAT A DERANGED, PSYCHOPATHIC MURDERER IS GOING TO EITHER KILL YOU IN YOUR SLEEP OR DESTROY YOU IN ANY SORT OF OPEN, PUBLIC SPACE."
 * A Glass in the Hand: After one jibe too many about his family, Harry makes the glass Marge is holding shatter. She assumes she was gripping it too hard, having done the same thing before.
 * The Alcatraz: Azkaban, which was first mentioned in Book 2, becomes central to the plot in this one.
 * Averted, since it's Sirius, not Harry, who is the first to escape.
 * Antagonist Title:
 * Anxiety Dreams
 * Awful Truth: Done twice, first with the story Harry overhears about how Sirius betrayed Harry's parents, and isn't just an insane criminal, then  Whether the real truth is slightly better or slightly worse is debatable. On one hand, the traitor  On the other hand
 * Berserk Button: When Snape calls Hermione an annoying know-it-all, Ron lashes out at Snape, despite having himself used that insult on Hermione.
 * And don't call Hagrid pathetic in front of Hermione, unless you're looking for a slap in the face...
 * This book shows us how McGonagall reacts to someone deliberately pulling off foul play in Quidditch. TWICE.
 * And don't forget Harry's reaction to Aunt Marge's taunts.
 * Beware the Nice Ones: At the climax of the book when he and  confront
 * Book Ends: The first and last chapters are called "Owl Post" and "Owl Post Again", respectively.
 * Burn the Witch: Lampshaded: Harry's over-the-summer essay is about how pointless Medieval witch burnings were, since the few times the victim was a wizard and not a poor ordinary Muggle, they could simply cast a flame-freezing charm and pretend to be suffering.
 * They go on to mention that some witches and wizards allowed themselves to be caught and burned multiple times because they liked the fact that it felt like being tickled.
 * Care Bear Stare: Riddikulus (laugh!) has this effect on boggarts and Expecto Patronum (think happy thoughts!) on Dementors.
 * Cassandra Truth: Due to the convoluted truth of what really happened that night, Harry has a hard time convincing anybody. Also done comically, as Trelawney doesn't believe a prophecy.
 * Cats Are Mean: Ron firmly believes this for most of the book.
 * Cerebus Syndrome: Mark says it best:

"Trelawney: My dears! Which of you left his seat first? Which? McGonagall: I doubt it will make much difference, unless a mad axe-man is waiting outside the doors to slaughter the first into the Entrance Hall."
 * Chekhov's Gun: The series has its own page.
 * Contrived Coincidence:
 * You just blew my mind.
 * Harry just happens to get his hands on the Marauder's Map the very same year that one of its creators is teaching at Hogwarts.
 * All of this thereby leading to Fridge Brilliance. The ultimate result of these events is that
 * Cool Teacher: Lupin.
 * Covert Pervert: A History of Magic contains an amusing little anecdote: witches and wizards who were caught and burned at the stake cast a charm that would protect them from the fire while all they felt was a gentle tickling sensation. Wendelin the Weird enjoyed it so much that she allowed herself to be caught forty-seven times. Yep, she definitely enjoyed it.
 * Cruel Mercy: Harry asks to spare 's life, but not because he feels sorry for him, he just doesn't want them to become murderers. "He can go to Azkaban. If anyone deserves that place, he does."
 * Darker and Edgier: This is where the series took a darker turn though the previous novel had some darker elements.
 * Dirty Coward:
 * Disappointed in You: Lupin.
 * Doctor's Orders: Madam Pomphrey asserted herself quite strongly, if not always successfully, when authority figures wanted to speak to students in her care.
 * Does This Remind You of Anything?: Lupin's werewolf condition and the wizarding community's reactions to it, may be a social commentary on living with HIV.
 * A number of people (including the director of the movie) believed that Lupin was gay, so it could also be a metaphor for homosexuality; however, Rowling didn't write the character as gay and explicitly stated it was an HIV metaphor, so the signs don't fit quite as neatly.
 * In the Movie, Harry is under his covers using his wand and hiding every time Uncle Vernon peeks in.
 * Dynamic Entry: [Lupin busts the door open] "EXPELLIARMUS!"
 * Emotion Eater: The Dementors.
 * Empty Shell: The result of the Dementor's Kiss.
 * Everybody Lives: Along with Chamber of Secrets, the only book in the series where no character dies (though several characters die in the Backstory).
 * Evil Former Friend:, although evil is too respectful a word to describe him.
 * Evil Detecting Cat: Crookshanks.
 * Justified in that Word of God stated that Crookshanks is half-Kneazle, a magical cat-like animal that can tell if someone is untrustworthy.
 * Extreme Melee Revenge: When Harry first meets . Harry becomes so enraged that.
 * Fake Kill Scare: At one point, they hear what they think is the hippogriff being executed.
 * Fantastic Time Management:
 * Fate Worse Than Death. The Dementor's Kiss.
 * Finger-Snap Lighter: Lupin.
 * Foreshadowing: Lupin teaching Harry's class how to deal with the boggart, a magical creature that is warded off with the combination of a spell and positive thoughts, foreshadowing him teaching Harry how to deal with Dementors.
 * Dumbledore mentioning to Harry that Trelawney's current record is having only two accurate prophecies made.
 * Game Breaking Bug: The time-turner has the potential to be this for the entire series; much like the infamous Lord of the Rings "why didn't they just use the eagles?" Plot Hole, many have questioned why somebody didn't just use a time-turner to stop all the bad stuff from ever happening?
 * Somewhat justified in that Harry and Hermione don't actually change the past, but rather play out a Stable Time Loop. It's also mentioned that whenever someone does try to use one to make actual changes, it always goes very badly.
 * Then
 * Getting Crap Past the Radar: Four books before Molly Weasley made it cool, Aunt Marge calls Harry's mother a bitch.
 * Since Aunt Marge is a professional dog breeder, this may be a Double Entendre.
 * "You see it in dogs all the time, if there's something wrong with the bitch, there's something wrong with the pup." Double Entendre indeedy.
 * She might be using "pup" as a double entendre as well. "Pup" can mean "a cheeky or arrogant boy or young man", which would fit Aunt Marge's view of Harry.
 * Girls with Moustaches: Aunt Marge, in addition to being 'large, beefy and purple-faced,' has a small mustache.
 * Golden Mean Fallacy: Lupin explains that this is one of the advantages to tackling a boggart in groups. It might try and combine two peoples' fears and end up with something a lot less scary than either of them.
 * Gone Horribly Right: The purpose behind telling no one that was to make sure everyone went after Sirius Black. It worked.
 * I'm Standing Right Here: Aunt Marge makes several disparaging remarks about Harry and his parents while sitting at the same table as Harry. Harry spends most of the week trying very, very hard to think about something else.
 * I Will Tear Your Arms Off: Hagrid says that if he had known Sirius' role in the Potters' death, he would have ripped him limb from limb. Hagrid is a half-giant, so a threat like this should be taken very seriously.
 * Hagrid is a slightly less hairy Chewbacca?
 * Intellectual Animal: The Wolfsbane Potion sort of invokes this. When a werewolf drinks it, they are able to keep their mind human when transformed.
 * It Was a Gift:
 * Kick the Dog: It's bad enough that Snape belittles and insults Neville in his own classes...but to have a small rant about how useless he is to another teacher is beyond cruel.
 * Know-Nothing Know-It-All: Snape has a moment of this when subbing for Lupin, claiming that the Kappa is more commonly found in Mongolia when it's actually Japanese. This gets followed up on in Fantastic Beasts: "Snape hasn't read this."
 * Laughing Mad: Offscreen, Sirius when he's arrested, which certainly doesn't help his case, even though The Reveal makes it obvious that it was due to
 * MacGuffin Location: Azkaban.
 * Moment of Weakness: Harry's blowing up Aunt Marge.
 * My Friends and Zoidberg: Oliver Wood does it to himself, when he lists the members of the Quidditch team: "We've got three superb Chasers. We've got two unbeatable Beaters. And we've got a Seeker who has never failed to win us a match! (after long pause in which he realizes he's forgotten someone) And me."
 * Which leads to a rather heartwarming moment when the rest of the team (including Fred and George) say they think he's a great Keeper.
 * Narm: In-universe example: the Riddikulus spell involves making your worst fear funny.
 * Never the Selves Shall Meet
 * Overly Long Scream: Ron uses up two whole lines of text to scream "AAAAAAAAAAAAAAAAAAAAAARRRRRRRRRGH! NOOOOOOOOOOOOOOOOOOOOOOOOOOO!!!!!" after he wakes up to find Sirius Black standing over him with a knife.
 * Plot Hole: Again, the time-turner.
 * Power Incontinence: What happens when teen witches and wizards lose their temper.
 * The Quisling: In The Reveal, is found to be one.
 * Rage Quit: Hermione. And it is awesome.
 * Red Herring:
 * Rushed Inverted Reading: When Hermione tells Professor McGonagall about Harry getting a Firebolt for Christmas and then the teacher goes to temporarily confiscate it so that it can be checked for jinxes/hexes (on the chance that Sirius Black sent it), Hermione hides her face behind a book that she holds upside down.
 * Secret Keeper: The Trope Namer.
 * Secret Secret Keeper:
 * Stab the Salad:
 * Stable Time Loop: See also You Already Changed the Past and You Can't Fight Fate, below.
 * Steven Ulysses Perhero: Many instances throughout the series, but this book introduces two particularly good examples: Remus Lupin and Sirius Black.
 * Talking in Your Sleep
 * Thirteen Is Unlucky: Sirius Black's last crime before being imprisoned: murder of 13 people. Trelawney brings this up during the Christmas feast, claiming that "the first to rise will be the first to die". Harry and Ron get up at the same time.

"You don't understand! He would have killed me, Then you should have died! Died rather than betray your friends, as we would have done for you!"
 * Possible Foreshadowing/FridgeBrilliance, as it's mentioned earlier in the scene that
 * Time Travel
 * Time Travel Tense Trouble
 * Timey-Wimey Ball: Largely averted, but there is one slight inconsistency. Hermione mentions that a lot of wizards who have abused Time Travel ended up "killing their past or future selves". The immutable timeline model used should logically preclude killing your past self (although not killing your future self). Perhaps Hermione is mistaken, or exaggerating.
 * Or she's referring to the very first time someone goes back in time. Being a Stable Time Loop, there has to be a time where they actually go back. Then they panic and kill their past self, since there are two of that person in the time period. Someone else could easily see someone kill themselves, then see the killer vanish and report it.
 * Totem Pole Trench: Totem Pole Dementor Cloak, actually.
 * Tricked-Out Time
 * Trick Twist: And how!
 * Turncoat:, textbook.
 * Undying Loyalty:  and Lupin are furious that   was not this to James, because they would have been, not only to James, but to   as well.


 * Villains Want Mercy: begs Ron, Hermione and Harry to protect him from  and Remus (after he fails with his begging with them).
 * Weaksauce Weakness: Boggarts are defeated by laughter.
 * In "Prisoner of Azkaban", Boggarts are only defeated via laughter, and the "Riddikulus" charm simply changes the Boggart's appearance into something funny, to facilitate laughter. After this book, the "Riddikulus" charm seems to get rid of the Boggart on its own, without need for laughter.
 * Possibly. The Boggart in Book Five shows no real sign of being "defeated", merely stuffed back into hiding by Lupin, who has long since learned to live with his fear of . In those grim circumstances, it's not likely anyone feels much like laughing, making the Boggart a monster that is most terrifying when things are already bad -- a living incarnation of It Got Worse.
 * Weirder Than Usual: Harry and Dumbledore regarding Trelawney. When the Eccentric Mentor has to ask "Stranger than usual, you mean?"...
 * "What Do They Fear?" Episode: Chapter 7. Lupin gives the class a practical lesson in dealing with the shape-shifting boggart. He sneaks around giving Harry a go for fear of it turning into Voldemort.
 * What the Hell, Hero?: Hagrid to Harry and Ron for alienating Hermione for most of the book. Later,
 * White Sheep:
 * You Already Changed the Past: The Stable Time Loop. Which renders all those Fan Fics in which the characters Peggy Sue themselves back in time to fix things all the more incompatible with the Canon).
 * You Can't Fight Fate: See also You Already Changed the Past.
 * You Dirty Rat:  full stop. One has to wonder how James, , and Lupin didn't get suspicious about this, especially since Word of God says that an animal form is automatic and cannot be chosen by the wizard.
