Chekhov's Gun/Literature: Difference between revisions

Line 1:

* In [[Dan Abnett]]'s ''[[~~Gaunts~~ Ghosts]]'' novel ''Honour Guard'', there is a very brief, off-handed scene at the beginning of the novel where Captain Daur is handed a small, insignificant trinket by an old woman who seems insistent that he keep it. At the end of the novel, a psychic vision reveals to Daur and other Ghosts that this trinket is the firing key for Saint Sabbat's massive Chaos-frying psychic weapons system buried underneath her tomb.

* In [[Dan Abnett]]'s ''[[Gaunt's Ghosts]]'' novel ''Honour Guard'', there is a very brief, off-handed scene at the beginning of the novel where Captain Daur is handed a small, insignificant trinket by an old woman who seems insistent that he keep it. At the end of the novel, a psychic vision reveals to Daur and other Ghosts that this trinket is the firing key for Saint Sabbat's massive Chaos-frying psychic weapons system buried underneath her tomb.

* [[Dan Abnett]]'s ''[[Warhammer 40000]]'' novel ''[[Brothers of the Snake]]'' opens with a Space Marine dealing with a planet invaded by Dark Eldar. Much later, the Marines realize that their purpose there has had repercussions.

* [[Douglas Adams]]' ''[[The Hitchhikers Guide to The Galaxy (~~Literature~~)|The Hitchhikers Guide to The Galaxy]]'' uses this trope ad nauseam when it comes to a Hitchhiker's towel.

* [[Douglas Adams]]' ''[[The Hitchhikers Guide to The Galaxy (novel)|The Hitchhikers Guide to The Galaxy]]'' uses this trope ad nauseam when it comes to a Hitchhiker's towel.

** ''Hitchhiker'''s does this with everything but towels. Towels are clearly stated as important from the beginning.

** The character of Agrajag is a mix of Karmic Retribution and Chekhov's Arsenal. In the first book, approaching Magrathea, it is referenced that two missiles were turned by the infinite improbability drive into a whale and a bowl of petunias. The whale's thought-processes as it falls to Earth are described in detail, and it is stated that the bowl of petunias' only thought was 'Oh no not again'. At the very beginning, reference is made to 'eating oysters' to provide background to an event. Elsewhere, Arthur talks about 'this damn fly', before remarking 'Got it!' At the beginning of the third book/Tertiary Phase, it references that Arthur kills a rabbit and makes a bag out of its skin. He teleports to Lord's Cricket Ground - where his sudden materialisation gives a man with a heart condition such a shock he has a heart attack and dies, and Arthur's aforementioned love of cricket is reiterated - and the bag is replaced for some strange reason with another one. He expresses his love for the lost bag, and talks about a bag he lost at an airport once coming back from holiday, which had a bottle of retsina in it. Later on, he teleports somewhere, but is hijacked and ends up in some form of mountain, where he is confronted by a monstrous creature - with hugely impractical sharp teeth - who reveals that all of the creatures Arthur has ever killed in his life were various reincarnations of itself, including the heart-attack man, the bowl of petunias ('cruelly dragged back into life after I had given up'), and the rabbit, 'whose skin-bag', Agrajag noticed, 'he had lost'. Agrajag then accidentally stabs himself through the brain with the teeth, before self-destructing the mountain. Arthur escapes by learning to fly - a long-running Hitch-Hikers' joke in the books, which states that the trick to flying is to be distracted when throwing yourself at the ground, causing you to miss - after noticing the bag he thought he had lost at the airport a long time before. He then rejoins his friends at a party in a flying house, which they are prevented from entering for not having a bottle. He gets the bottle of retsina out of the bag, and they enter the party to save the universe. Thus reducing Agrajag's character to a device enabling the characters to overcome an unnecessary obstacle to get into the party. Into which MASSES of background has been invested over the course of the two previous books and the rest of the book, along with the further two books.

Line 8:

*** At which point, the "hugely impractical teeth" come back into play, as Arthur ended up in the place he was trying to avoid because he had mistaken {{spoiler|Stavro Mueller's--Beta}}, the location that said death was supposed to take place, for a planet named Stavromula Beta due to Agrajag's monstrous form being a tad hard to understand.

* [[Jim Butcher]] ''loves'' these.

** One of the baddies in the first ''[[The Dresden Files ~~(Literature)~~|Dresden Files]]'' book, ''Storm Front'', {{spoiler|is motivated to get revenge on John Marcone because her daughter was killed in a mafia shootout}}. ''Nine books later'' we find out that {{spoiler|her daughter is the coma patient Marcone is protecting, the one he stole the Shroud of Turin to try and heal (in Book Five) and the guilt over which motivates him to protect innocents and help Harry out sometimes}}.

** One of the baddies in the first ''[[The Dresden Files|Dresden Files]]'' book, ''Storm Front'', {{spoiler|is motivated to get revenge on John Marcone because her daughter was killed in a mafia shootout}}. ''Nine books later'' we find out that {{spoiler|her daughter is the coma patient Marcone is protecting, the one he stole the Shroud of Turin to try and heal (in Book Five) and the guilt over which motivates him to protect innocents and help Harry out sometimes}}.

** In the beginning of ''[[~~The Dresden Files (Literature)|~~The Dresden Files]]'' book ''Death Masks'', while Harry and Ebeneezer McCoy discuss Harry's astronomy lessons under McCoy, they remember when they discovered "Asteroid Dresden", which turned out to be an old, disused Soviet satellite. At the end of the book {{spoiler|1=McCoy drags the satellite from orbit and drops it on the mansion of a [[Our Vampires Are Different|Red Court duke]], in retaliation for cheating in a duel against Dresden}}.

At the end of the book {{spoiler|1=McCoy drags the satellite from orbit and drops it on the mansion of a [[Our Vampires Are Different|Red Court duke]], in retaliation for cheating in a duel against Dresden}}.

** Another example which has yet to be resolved. In the 3rd book ''Grave Peril'', Harry's literal fairy godmother, Lea, receives a ritual athame from the book's big bad. Later in the same novel, it's used for an attack on Harry, and it's been referenced in multiple books since, constantly emphasizing its importance. 8 books later we still have no bloody idea what the thing is!

*** Also from ''Grave Peril'', [[Our Dragons Are Different|Ferrovax]].

*** In ''Dead Bead'', Cowl stated that there was so much that happened at that party that Dresden was either unaware of, or does not comprehend the consequences of. To quote Harry, "What an incredibly fucked-up night that was."

** ''Dead Beat'', where he throws a paragraph in describing the awesome nature of {{spoiler|[[Everything's Better ~~With~~ Dinosaurs|Sue]], the near-complete ''[[Tyrannosaurus Rex]]'' skeleton at the Field Museum.}} Seems fairly innocuous, since... well, it ''is'' cool. {{spoiler|He later [[Raising the Steaks|raises her from the dead]] in [[Crowning Moment of Awesome|the single most awesomely overblown moment in the entire series]].}} I doubt anyone saw ''that'' coming on their first reading of the book.

*** Also in ''Dead Beat'': at the beginning of the book, we're introduced to Butters' one-man polka suit. Butters, being the [[Bunny Ears Lawyer]] he is, refuses to leave it behind to be mauled by zombies and Harry has to wrestle it into the back of Billy and Georgia's SUV. {{spoiler|Said polka suit's drum happens to be the only thing around that's the right size to keep a beat going to control the zombie dinosaur.}}

** In ''Small Favor'', he even sets one up by the prominent ''failure'' to mention something that should have been there. {{spoiler|Harry's an [[Unreliable Narrator]], so when Mab messes with his head, we get the effects as well.}}

Line 26:

** Another one from ''The Lost World'': after a very close call with the T.rexes, Levine says that they're good parents. They're such good parents, that they probably teach their offspring how to hunt, by bringing small or weakened creatures to the nest for them to finish off. Well, guess what happens to {{spoiler|[[Corrupt Corporate Executive|Dodgson]]}} when the T.rex gets him but ''doesn't'' eat him outright. (Also a case of [[Karmic Death]], as the infant T.rex who ends up killing him is the one whose leg he had broken earlier.)

** ''The Lost World'' has plenty of these: Arby's printout of the Isla Sorna facilities (hint: {{spoiler|boathouse and river docks}};) Eddie's insistence on adding backup systems and safety devices in Thorne's vehicles without telling anyone; the observation cage with its prodigious resistance to impacts; the maia eggs stolen by King; [[Too Dumb to Live|Levine]]'s damn candy bars; also, the rifles armed with neurotoxins are finally put to good use during the raptor chase.

* Subverted in ''[[Two Thousand Ten Odyssey Two]]'' by [[Arthur C. Clarke ~~(Creator)~~]]. In the beginning of the book a mechanism is constructed to deactivate the to-be-repaired [[AI Is a Crapshoot|HAL 9000]] instantly in case it [[Kill All Humans|malfunctions again like it did in the first book]]. The remote control for this mechanism, a rigged pocket calculator, is given to one of the characters. Surprisingly, it is never used and the end of the book reveals that it wouldn't have worked anyway because it had been disabled at some point.

* [[Philip K Dick]]'s ''[[Paycheck]]'' is almost entirely composed of this trope. The hero Jennings has just had his memory erased of the top secret project he was working on, only to discover that before it happened he arranged to substitute his paycheck with several seemingly trivial and useless items, including a small piece of wire. Then he's arrested, whereupon it turns out the wire is just the right size to pick the lock of the squad car's back door. It seems the project was a window into the future, which Jennings used to see what was going to happen to him, and so every single one of the items has some purpose to help him stay alive and out of the bad guys' clutches. Half the fun of the story is just seeing what purpose all of them have.

Half the fun of the story is just seeing what purpose all of them have.

* The ''[[Thursday Next]]'' series is a truly fascinating juggling act of various plot threads that feature all kinds of little moments that pay off down the road, either in the book they appear in or several books later. Amazingly, judging by some statements [[Jasper Fforde]] has made it seems he really doesn't do that much planning ahead for the series; instead he just has an amazing memory for everything that has happened so far and can come up with ways to refer back to it all that all make perfect sense.

* [[William Gibson]]'s ''[[Neuromancer]]'' averts this: Molly gives Case a shuriken as a souvenir, and he keeps it with him for the entire book, never actually needing to use it in anger (he comments on this toward the end).

Line 35:

** You call that a long-term Gun? {{spoiler|Shar died at the beginning of book 1, and said that should richard need help of the night wisps, to say her name. He did it near the end of book 10.}}

** The {{spoiler|Sword of Truth itself, given to Richard in the first book, turns out to be the real key to unlocking the Magic of Orden in the last book, instead of all those magic prophecy books.}}

* Similarly to Bond, at the beginning of Anthony Horowitz's ''[[~~Alex Rider (Literature)|~~Alex Rider]]'' books and the film version of ''Stormbreaker,'' Alex is given a set of gadgets -- all of which will be used. In fact, most spy films involving gadgets do this, as if the equivalent of Q has the ability to see into the future.

In fact, most spy films involving gadgets do this, as if the equivalent of Q has the ability to see into the future.

** Some of the later books avoid this and have Alex given gadgets that don't get used. ''Snakehead'' in particular has an unusual way of using a [[Chekhov's Gun]] - Alex gets given a belt packed with a jungle survival kit. Although the belt gets confiscated by the [[Big Bad]] before it can be used (and Alex does end up stranded in the jungle), the fact that it was proves to be an important plot point when it helps Alex to figure out who [[The Mole]] is.

* The dumpy, mushroom-colored bonnet in [[Diana Wynne Jones]]' ''[[Howl's Moving Castle (~~Literature~~)|Howl's Moving Castle]]''. At first it's simply a cleverly-written joke when the story Sophie tells while making the bonnet comes true, but then {{spoiler|in the end, it turns out that Sophie is a somewhat powerful witch without even knowing it - she has the ability to dictate the fate of any inanimate object by speaking to it}}.

* In [[Stephen King]]'s ''[[~~Desperation (Literature)|~~Desperation]]'', a shotgun shell becomes a key item in the last few pages of the book {{spoiler|They use it as a blasting cap to detonate explosives that trap a demon / evil god in an abandoned mine.}}

** In ''[[~~Fourteen Oh Eight~~]]'' (just the story, not the film) the lucky Hawaiian shirt becomes a textbook example of the trope.

** In ''[[1408]]'' (just the story, not the film) the lucky Hawaiian shirt becomes a textbook example of the trope.

* [[Elizabeth Moon]]'s ''[[~~Vattas~~ War|Trading in Danger]]'' has two: the model kit and the fruitcakes given to the main character near the beginning both turn out to be very useful by the end, though neither in the way that's hinted at during the various times they are mentioned. {{spoiler|The model kit contains the makings of a communications beacon and the largest of the three fruitcakes holds a small fortune in diamonds and a letter.}}

* [[Larry Niven]] might just have pulled off the longest delay between the appearance of Chekhov's Gun and it's firing in the history of modern literature within the boundaries of his ''[[Known Space]]'' universe. In his 1966 short story ''At The Core'', Niven introduces the Quantum II hyperdrive, which is capable of moving a starship a light year in a minute and a quarter (as opposed to the Quantum I hyperdrive, which moves at a mere 3 days to the lightyear). In Niven's 2006 novel ''[[Ring World]]'s Children'', the Quantum II hyperdrive is used for it's ultimate purpose: to unilaterally end the Fringe War by removing the Ringworld from Known Space entirely. Thirty-eight years from mention to ultimate use just has to be some sort of record...

* Gary Paulsen's ''The Rifle'' is a story told from the point of view of a [[Chekhov's Gun]].

* In Peter Straub's "Ghost Story", Stella Hawthorne makes use of a Chekhov's Hatpin. Oddly, despite being a somewhat obvious example of the trope, it doesn't really affect the overall story very much.

* The {{spoiler|M25 London orbital motorway}} in ''[[~~Good Omens (Literature)|~~Good Omens]]'' seems like just one more example of how Crowley was able to use a little work to generate a lot of evil. It ends up {{spoiler|making it ''very'' difficult for several major players to reach the site of the Apocalypse, and-- perhaps worse-- destroying his [[Cool Car]]}}.

* [[Darkness Visible]] uses the phrase {{spoiler|"The Dark Tide shall rise"}} as a Chekhov's Gun, and also has the more physical examples of a bottle of nitroglycerine and Marsh's cigarette case.

* [[Terry Pratchett]] plays with this a lot:

** Used straight in ''[[Discworld ~~(Literature)~~/The Colour of Magic|The Colour of Magic]]'' where Rincewind rescues a small green frog from the ocean that ends up saving his life.

** Used straight in ''[[Discworld/The Colour of Magic|The Colour of Magic]]'' where Rincewind rescues a small green frog from the ocean that ends up saving his life.

*** Another instance in the same book has Rincewind throwing a bottle of wine at someone in an effort to distract him and escape; the man just uses magic to halt the bottle in mid air. About half a scene later, the magic wears off, and the bottle continues its interrupted journey, right into the face of a guard, distracting him and giving Rincewind the opportunity to escape.

** Also used straight in ''[[Discworld ~~(Literature)~~/The Light Fantastic|The Light Fantastic]]''. Having been established as a pathetic wizard in ''[[Discworld ~~(Literature)~~/The Colour of Magic|The Colour of Magic]]'', Rincewind is revealed to have come by this trait after reading a powerful grimoire and getting a single, powerful spell stuck in his brain. It is this exact spell that must be cast at the ''end'' of ''Fantastic'' to avert complete annihilation of the Disc.

** In ''[[Discworld ~~(Literature)~~/Small Gods|Small Gods]]'', the opening paragraphs discuss eagles picking up tortoises and dropping them to crack their shells, and says something to the effect of a tortoise possibly taking advantage of this someday. Close to the end of the book Om, a god trapped in turtle form, gets an eagle to drop him on Vorbis's head (by [[Groin Attack|threatening said eagle's sexual organs]]), killing Vorbis, and causing the crowd that's watching to become believers of Om.

*** Granted, it's a [[You Fail Biology Forever]] (eagle gonads are internal), but it's still funny.

**** This takes place in a world where you can inherit scars from your parents and powers from your ADOPTED grandfather. All science on Discworld takes a backseat to the [[Rule of Funny]].

***** Not just the rule of funny but the fact that the Discworld runs on Narrative Imperative and the story itself displays the power of mass belief. If the people in the area believe eagles have external gonads and the story being played out requires it, eagles (or ''this'' eagle anyway) will have them.

** Subverted ''[[Discworld ~~(Literature)~~/Maskerade|Maskerade]]''. Several characters point out, in increasingly ominous tones, that the enormous crystal chandelier in the Ankh-Morpork Opera House looks like "an accident waiting to happen", but unlike in ''[[Phantom of the Opera]]'' (which ''Maskerade'' parodies), the chandelier completely fails to be dropped on anyone. Not that the bad guy didn't try.

Not that the bad guy didn't try.

** Subverted in ''[[Discworld ~~(Literature)~~/Feet of Clay|Feet of Clay]]'' where the main mystery of the book is how Lord Vetinari is being poisoned despite his food being safe. Repeated references are made to the horrible green wallpaper in his bedroom, and the implication is that it may have something to do with it, emphasized by the popular theory that Napoleon was killed by green wallpaper (arsenic was once commonly used in green paint). The wallpaper has nothing to do with it, and Pratchett has admitted to getting emails that amount to "We were sure it was the wallpaper, you bastard!" When one re-reads the book, one discovers that the clues to the ''real'' murder weapon were there all along ...

** Used Straight in ''[[Discworld ~~(Literature)~~/Thief of Time|Thief of Time]]'' where Lu-Tze shows his apprentice how yetis "save" their lives and create a sort of premonition ability. He then proceeds to use it later on. One knows he is about to do so when the fact "they cut off his head" is mentioned, because this is how the ability was demonstrated with the yeti.

** Another fine example in ''[[Discworld ~~(Literature)~~/Interesting Times|Interesting Times]]'' where an experimental Discworld cannon is used as teleportation counterweight to send Rincewind to the other side of the disc. They send it back the way it was (ready to fire).

** Pratchett can place a Chekhov's Gun so smoothly, you barely even notice it's there. In ''[[Discworld ~~(Literature)~~/Reaper Man|Reaper Man]]'', Miss Flitworth is seen brewing up rat poison in the kitchen, which appears (along with the chicken's demise) to be purely a part of Bill Door's lessons in what death means to mortal creatures, human or animal. Yet this passing reference also provides the basis for the debut of one of [[~~Discworld (Literature)|~~Discworld]]'s perennial scene-stealers, the Death of Rats.

** There's another in ''[[Discworld ~~(Literature)~~/Hogfather|Hogfather]]'': Archancellor Ridcully offhandedly mentions that someone with access to part of another person's body has the power to control them. Turns out to be a major plot point.

** In ''[[Discworld ~~(Literature)~~/The Fifth Elephant|The Fifth Elephant]]'', Vimes finds a mortar flare and reads the instructions, "Light fuse. Do not place in mouth." He also explains why it is a stupid weapon since it can't be aimed. Both of these come into play at the end of the book.

** A pretty subtle one appears in ''[[Discworld ~~(Literature)~~/I Shall Wear Midnight|I Shall Wear Midnight]]'', where the Nac Mac Feegles hitch a ride on Tiffany's broomstick, and Daft Wullie, for no apparent reason at all, decides to start a fire while they're up in the air, damaging the broomstick and forcing them to land. Tiffany's reproach hint that this isn't even the ''first'' time Wullie has done this exact thing. But towards the very end of the book, Daft Wullie's eagerness for lighting fires comes in handy, when Preston desperately needs to start a fire, but all his matches are damp and useless... and guess who shows up out of nowhere to lend him some dry matches and help get the fire going?

* ''[[Nightmare]]'' by Willo Davis Roberts. About a third of the way into the story, a side character finds shotgun shells in the back of their RV. These end up saving them from death when the same side character uses them as a diversion making the [[Big Bad]]'s sidekick drop his shotgun.

Line 72:

** Almost all of the items given to the Fellowship by Galadriel. Whether it's characters not being spotted from afar due to their elvish cloaks, a supernatural flashlight, magic dirt, or even a belt that only serves to identify a dead character for sure.

*** Well, except for Gimli's Galadriel-hair. He just made a necklace out of it...

*** As examples of this trope turning into an [[Ass Pull]], the scene where Galadriel gives these items to the Fellowship was edited out of the [[The Lord of the Rings (~~Film~~)|theatrical release]], yet most of them are specifically referenced during the remainder of the trilogy.

*** In addition to Galadriel's gifts, there's the random coils of rope that the elves of Lorien stow in the Fellowship's boats and which Sam takes a fancy to, having moaned about not having any rope since they set off. It takes him a while to remember it when Frodo is stuck halfway down a cliff.

** The hobbits first acquire enchanted daggers <ref>of Numenorean make, not Elven; that's why they're grave-goods in the lost North-Kingdom</ref> in the Barrow-Downs during Book 1, a relatively unimportant plot point until Book 5 when {{spoiler|Merry stabs the Lord of the Nazgul behind the knee, weakening him for the final kill by Eowyn}}. This is made possible only by the fact that {{spoiler|Merry's blade was specifically designed for combat against the enemies in Angmar, under the rule of this very foe, the Witch-King of Angmar}}.

Line 78:

** Arguably, the One Ring is an example of this trope in ''[[The Hobbit]]'' itself. It starts out as an ordinary ring that Bilbo happens to find on the ground, only for him to discover that it happens to be a magic ring that can turn him invisible and pave the way for him to get into adventuring. Not bad!

** Aragorn is potentially this, he starts out being mentioned when Gandalf gives his history of the ring but by the time he actually appears to Frodo, most readers have forgotten he ever existed, then Gandalf mentions that he had mentioned Aragorn.

* Happens often enough in the ''[[Harry Potter (~~Literature~~)|Harry Potter]]'' series that fans used to obsess over seemingly every little detail in the books in an often fruitless attempt to figure out what would happen in future installments... but only a few picked up on Dumbledore's put-outer, i.e. Deluminator, introduced at the very beginning of book one, which became important in the seventh and final book (a long-term Chekhov's Gun that was apparently too subtle and too weirdly-used for the fandom to easily notice). It's pointedly reintroduced towards the beginning of the book, making it suddenly a whole lot less subtle and a more traditional Chekhov's Gun, but veiling its importance for that long, in hindsight, is impressive given we're talking about roughly a few ''million'' obsessive fans here. The Harry Potter series [[Chekhov's Gun/Harry Potter|has its own page of Chekhov's Guns]], but here are a few notable examples.

* Happens often enough in the ''[[Harry Potter (novel)|Harry Potter]]'' series that fans used to obsess over seemingly every little detail in the books in an often fruitless attempt to figure out what would happen in future installments... but only a few picked up on Dumbledore's put-outer, i.e. Deluminator, introduced at the very beginning of book one, which became important in the seventh and final book (a long-term Chekhov's Gun that was apparently too subtle and too weirdly-used for the fandom to easily notice). It's pointedly reintroduced towards the beginning of the book, making it suddenly a whole lot less subtle and a more traditional Chekhov's Gun, but veiling its importance for that long, in hindsight, is impressive given we're talking about roughly a few ''million'' obsessive fans here. The Harry Potter series [[Chekhov's Gun/Harry Potter|has its own page of Chekhov's Guns]], but here are a few notable examples.

** One object and action regarding said object is also mentioned in the first book, and built upon in significance in the subsequent books: the Vanishing Cabinet.

** And in contrast, the "chess game" scene in the climax of the first book was expected, quite firmly and very widely, to be of help in predicting one of the people who was going to die in the final book. It wasn't.

Line 91:

** The various Horcruxes tended to be [[Chekhov's Gun|Chekhov's Guns]] more often than not. Figuring out who "RAB" was before the last book came out was easy, but remembering that there was a locket in the house of Black, not so much. And who would've remembered about the diadem, first mentioned in ''Half-Blood Prince'', hidden in the Room of Requirement? There was also the diary (destroyed in the same book it debuted, ''Chamber of Secrets'', but [[Chekhov's Boomerang|became important again when the concept of Horcruxes was first introduced four books later]]), Nagini (debuted in ''Goblet of Fire'', and became a Horcrux shortly ''after'' her debut as Voldemort was going to make his last Horcrux when he killed the Potters, but never got around to it {{spoiler|(or so he thought)}}, {{spoiler|''Harry'' (we've known about the lightning-bolt scar since the very beginning, and his connection to Voldemort established when he first gets his wand, but the big hint that he is inherently "connected" to Voldemort comes in ''Order of the Phoenix''}}, and the ring, which was already a destroyed Horcrux when it debuted in ''Half-Blood Prince'', but turned out to also be {{spoiler|one of the three Deathly Hallows}}. Only the goblet of Hufflepuff appeared solely as a Horcrux.

** In ''Prisoner of Azkaban'', Harry tells Dumbledore that Trelawney went all odd and recited some verse to him. Dumbledore offhandedly comments that it appears to be her second real prophecy ever and he should give her a pay rise. {{spoiler|Her ''first'' real prophecy turns out to be a crucial [[MacGuffin]] in ''Order of the Phoenix''.}}

** There are so many important Chekhov's Guns in the series, in fact, that they can often cause [[Continuity Lock Out]] in [[Harry Potter (~~Film~~)|the movies]]. Conversely, some of the movies set up Chekhov's Guns from the books and then ''don't'' fire them. An example is the Chocolate frog card of Dumbledore in the first one. In the book, Harry reads the card on the train but only later notices the reference to Nicholas Flamel, which leads Hermione to the book she had borrowed. In the movie, a scene that was deleted has Harry reading the card to Ron and Hermione, again leading to Hermione finding Flamel in her book.

** ''Half-Blood Price'' has the bezoar, mentioned in passing at the start of the ''first'' book, which Harry uses {{spoiler|to save Ron's life}}.

** ''Deathly Hallows'' brings forth the Golden Snitch from the first Quidditch match that Harry ever played, which is revealed {{spoiler|to contain the Resurrection Stone}}.

Line 98:

** In ''Chamber of Secrets'', Malfoy is seen looking at a cursed opal necklace in Borgin and Burkes. Four books later, he uses it in an attempt to murder Dumbledore.

** When Luna Lovegood is introduced at the beginning of ''[[Harry Potter (Franchise)/Harry Potter and The Order of The Phoenix|Order of the Phoenix]]'', she is seen reading ''The Quibbler'', the Wizarding World's equivalent of the ''[[Weekly World News]]''. After Hermione calls it rubbish, Luna angrily says that her father is the editor. This seems to just be a nice character-establishing moment until nearly 400 pages later, when Hermione and Luna team up to get an interview with Harry published in ''The Quibbler''.

* ''[[~~Honor Harrington (Literature)|~~Honor Harrington]]'' gets this one in an interesting manner. After the events of the first book, in which Honor and her crew successfully destroy a Q-ship (essentially a warship disguised as a freighter) before it can spark a war, the ship's home nation demands Honor be extradited for murder charges on the grounds that she massacred the crew of an innocent freighter. It's an obvious propaganda ploy, and nobody pays much attention, but later in the series (after said war breaks out anyway), Honor is captured and the murder conviction the court handed down without her present is used as a pretext to ignore interstellar treaties dealing with the treatment of prisoners.

** The first book also has a Gun that used a bit earlier in the series: the beginning of the first book shows Honor's ship getting outfitted with a Gravity Lance, which she has to figure out a way to use in war games. It is repeatedly discussed how impractical the device is for real combat situation. This same ship is the one she used against the Q-ship mentioned above. In the end, the only way Honor can defeat the Q-ship is by using the Gravity Lance.

** The Gravity Lance ''was'' impractical. The reason it's the only way she can destroy the Q-ship is because it's the only effective weapon she really ''has'' because of the weapon refit (which stripped her ship of most of its conventional armaments), and she can only use it by getting suicidally close to the Q-ship. It's mentioned by several characters that she could have done a ''lot'' more damage to the Q-ship right off the bat if the ship hadn't been refitted at the beginning of the book. The only reason she won was because of overconfidence on the part of the Q-ship captain.

Line 108:

* At the beginning of ''The Wide Window'', the third book in the ''[[A Series of Unfortunate Events]]'' series, Mr. Poe gives the Baudelaire orphans some peppermints - forgetting that the orphans are allergic to them. Later in the story, they end up coming in handy - as the orphans take advantage of their peppermint allergy to get themselves out of a sticky situation.

* Quite literal use in 'Silver Skull' in ''[[The Shadow]]'' series of pulps, when a gun The Shadow gives to a companion gets smuggled past captors and across the USA, only to be handed back to the Shadow at the climax when his own brace runs empty.

* In the short story "[[The ~~Toymakers~~ Workshop ~~(Literature)~~|The Toymakers Workshop]]", Mr. Silver takes some supplies from a whimpering box while working on the doll. As it turns out, {{spoiler|the box contains the girl he kidnapped and is creating a replacement for.}}

* In the short story "[[The Toymaker's Workshop|The Toymakers Workshop]]", Mr. Silver takes some supplies from a whimpering box while working on the doll. As it turns out, {{spoiler|the box contains the girl he kidnapped and is creating a replacement for.}}

* An ironic version in Camus' ''[[The Stranger]]'': Meursault and Raymond get into a fight with some men, including the brother of Raymond's ex-girlfriend. Meursault takes away Raymond's gun so that Raymond doesn't do anything rash. Later on, Meursault encounters the brother, and shoots him for no reason.

* In the ''[[~~Skulduggery Pleasant (Literature)|~~Skulduggery Pleasant]]'' novel, the main character's (a skeleton) head is a fake: his real skull was stolen by goblins. This is mentioned as trivia at the time, but becomes important when {{spoiler|they need a part of him to bring him back from another dimension at the end of the third book.}}

* [[Alastair Reynolds|Chasm City]] manages to feature Chekhov's Brain Surgery. Early on, we hear about an assassin who used [[Grand Theft Me]] to kill and replace a loyal retainer. At the climax, we learn that {{spoiler|the protagonist used the same process in reverse, to overwrite his own personality with a different one.}}

* Although Walter Moers has something of a soft spot for the [[Deus Ex Machina]], he included at least three of these in ''The 13 1/2 Lives of Captain Bluebear''. {{spoiler|Rumo the Wolpertinger, Nightingale's darkness from deep space, and - oddly enough - Deus X. Machina himself}}.

Line 119:

* Used in almost many of Steven Brust's ''[[Dragaera]]'' books, but most blatantly in ''Taltos''. {{spoiler|Kiera gives Vlad a vial of a goddess's blood for no clear reason at the time, which later in the book, and years later in the story, he uses to resolve a problem years later in the storyline.}}

* Used a ''lot'' in ''[[Deltora Quest]]'' series. If it's mentioned or introduced near the beginning of the book, it'll be relevant later (or ''way'' later in the series). Most of which are relevant to [[Only Smart People May Pass|puzzles]] (e.g. the names of the Diamond Guardian's pets), plot twists or eventual [[The Reveal|reveal]].

* Sometimes used, sometimes not in the ''[[~~Vorkosigan Saga (Literature)|~~Vorkosigan Saga]]''. Vorlopolous's Law was used as a straightforward Checkhov's Gun in ''Warrior's Apprentice'', likewise Imperial Auditors in ''Memory''. But in ''Barrayar'' the story behind the Emperor's Birthday Present is introduced in exactly the same way and then isn't used at all.

* Pervasive in ''[[Catch-22]]''. Many characters or events are briefly mentioned only to become fleshed out in later chapters. E.g. Major Major.

* In ''[[Memory ~~Sorrowand~~ Thorn]]'', the White Arrow that [[The Fair Folk|the Sitha prince, Jiriki]], gives [[The Hero|Simon]] as a symbol of [[I Owe You My Life|his life-debt]], is treated throughout the story as no more than a particularly valuable possession, symbolic of Simon's [[Character Development]]. There are hints dropped, however, that it's a potent magical artifact, [[Foreshadowing]] the moment when it's used to {{spoiler|kill the [[Big Bad|Storm King's]] [[Demonic Possession|physical host]]}}.

* Lampshaded in [[Smoke and Shadows|''Smoke and Ashes'']]: "Raise your hand everyone who's surprised by this." "According to Chekhov, you should never hang a coffee shop on the wall unless you intend to use it."

* In ''[[~~Remote Man (Literature)|~~Remote Man]]'', Janet buys a car in poor condition, which makes a horrible noise and has a noticeable crack in the exhaust pipe. During the climactic car chase, the exhaust falls off and hits the villain's car, causing him to flip over.

* [[The Father Luke Wolfe Trilogy]] uses Chekhov's Guns heavily.

** In ''Father, Forgive Them'', a motion-activated talking frog and a magic eight-ball are mentioned to be on the counter near the light switch. When {{spoiler|Dr. Brandt is holding Father Wolfe at [[Deadly Doctor|syringe-point]], Father turns on the light, which sets the frog to talking, which distracts Dr. Brandt long enough for Father to smash the syringe with the eight-ball}}.

** In ''Cold Comfort'', the electronic equipment mentioned in the beginning of the book is hooked up to force a public confession from the murderer.

** In ''Zero Tolerance'', a student threatens to {{spoiler|accuse Father Wolfe of molestation unless given a good grade. The teacher who had fixed the computers in Father Wolfe's classroom back in ''Cold Comfort'' had left a small hole for wiring between their two classrooms, through which he [[Engineered Public Confession|videotaped the student's threat]]}}.

* In ''[[Rainbow Six]]'', the need established earlier on for cellphone jamming technology pays off majorly when it {{spoiler|helps foil the PIRA attack.}} The <s> [[Battlefield (~~Video Game~~)|pussy-ass]]</s> [[Battlefield (~~Video Game~~)|heartbeat monitors]] Tim Noonan tries out also come in handy at the end against the [[Big Bad]]'s crew.

* Early in [[Lois McMaster Bujold]]'s ''[[Vorkosigan Saga ~~(Literature)~~|Barrayar]]'', Cordelia purchases a [[Sword Cane|swordstick]] for Lt. Koudelka. This helps to further establishes Cordelia's [[Fish Out of Water]] status on Barrayar (not knowing that non-Vor are not permitted to own personal weapons -- A loophole permitting Koudelka's superior officer to ''issue'' the weapon gets around this), and keeps the early plot going through a couple of character-driven sequences. The swordstick becomes a vital part of the [[Crowning Moment of Awesome|shopping trip to the capital]], where both the powerful spring-loaded sheath and the superb blade -- as demonstrated when she bought it -- come in very handy indeed.

* In Sandra Cisneros' ''Caramelo'', it is played straight [[Chekhov's Gunman|with people]] as well as the reboso, but completely inverted with other objects, to the point that every setting the narrator goes to will have rooms or objects lavishly and poetically described, and then almost none of them will ever come up again in the story.

* Terry Pratchett doesn't only do this in Discworld. ''[[~~Nation (Literature)|~~Nation]]'' features its hero Mau undergoing his tribe's manhood ritual, which ends with building a canoe with an axe that is always left stuck in the same tree by the last person who did the ritual. During his climactic duel with Cox, he notices that the tree he's hiding under has some axe marks in it...

* Despite [[PG ~~Wodehouse~~ ~~(Creator)~~|PG Wodehouse]] being a writer of light comedy, these turn up regularly in his work. If some seemingly irrelevant object or person gets mentioned in a Wodehouse story, no matter how briefly and casually, there's a very good chance it/they will become a plot-point before the story's over.

* ''Sisterhood'' series by [[Fern Michaels]]: Early on in the series, there is an teddy bear called Willie, who belonged to Barbara Rutledge. Barbara's ghost mentions Willie more than once, then eventually it is forgotten. However, at the end of ''Home Free'', Barbara's ghost tells her mother that she is going to give Willie to Jack Emery and Nikki Quinn's child! Gold shields, which give anyone (usually hand-picked [[FBI Agent|FBI agents]]) who possesses them carte blanche and s/he can answer only to the president, are brought up a lot early on. Later on, they are not even mentioned. However, the book ''Home Free'' has president Martine Connor set up an organization that will be composed of the Vigilantes, and there are 14 gold shields, one given out to each member of the organization! ''Hide And Seek'' has Mitch Riley, assistant director in the FBI and a [[J Edgar Hoover]] wannabe, keeping loads of files on supposedly everyone. Between his wife and the Vigilantes, his files get snatched from him and put somewhere where they'll never see the light of day. However, ''Deja Vu'' has the Vigilantes needing to look through those files on Henry "Hank" Jellicoe. It turns out that Mitch not only has files on Henry, but there are at least 6 boxes worth of files on Jellicoe!

* [[Badass Normal|Carmela]]'s {{spoiler|"magic closet" worldgate}} in Book 9 of the ''[[Young Wizards]]'' series.

* The first book in the ''[[Knight and Rogue Series]]'' has a scene early on where Fisk gives Michael grief for an old, now illegal pracitce where nobles would get their wives by giving them a drug called Aquilas to make them compliant, and Michael indignantly insists that for generations no one in his family has resorted to such a horrible method. It's actually mentioned even earlier, within the first few pages, while they're breaking a woman out of what they believed to be a cruel lord's tower, and were worried she may have been dosed. Towards the end of the book they use Aquilas on that very woman, who was in fact a imprisoned murder suspect, in able to break out of her own stronghold.

* In Victor Hugo's novel ''[[Les Misérables (~~Literature~~)|Les Misérables]]'', Éponine writes the sentence "The cops are here" to prove to Marius that she is literate. Later on, Marius uses the note to save Leblanc's {{spoiler|(aka Jean Valjean's)}} life.
