A series of novels by British-born Lee Child, about [[YanksWithTanks ex-Military Policeman]] Jack Reacher, WalkingTheEarth after mustering out from over a decade of service. A MilitaryBrat, having spent his younger years being posted all round the world, he decides to get a closer look at his home country. On his journeys across America he stumbles across his fair share of forgers, smugglers, gun runners, drug dealers and assassins. [[BlatantLies He then proceeds to sit down with each of them in turn and have civilized discussions -over a lovely cup of tea- why they really should stop all this unpleasant business and whatnot]].

Received a film adaptation based on the novel ''One Shot'' titled ''Film/JackReacher'', which was directed and written by Christopher [=McQuarrie=], starring TomCruise in the lead role with Rosamund Pike, Richard Jenkins, Robert Duvall, and Creator/WernerHerzog also starring.

!!Tropes applying to this series:

* AirportNovel: According to TheOtherWiki, Child writes these novels as such, and doesn't apologize for it.
* AloneWithThePsycho: In ''Gone Tomorrow'' a suicide victim's son picks up a woman in a bar [[spoiler:who turns out to be a terrorist. It doesn't end well for him.]]
* AmateurSleuth: Not really, as Reacher spent over a decade as a decorated and skilled investigative MP, but since mustering out he's technically "amateur".
* {{Anticlimax}}: In almost every book. Child spends a couple of hundred pages having the villain of the day do some truly horrendous things, so that only the most CruelAndUnusualDeath will satisfy the reader. When Reacher finally catches up with him, though, the villain's death inevitably takes less than a sentence, and usually occurs by BoomHeadshot. Most times, the villains don't even see it coming. Likely intentional, to illustrate Reacher's ruthless efficiency.
** Lampshaded in the first novel ''Killing Floor'' where Reacher reflects on how the scene would play out in a book or a movie as he contemplates taking down the bad guy, and how direct confrontation isn't actually practical. Of course, he then proceeds to have a fist-fight with the guy.
* AsYouKnow: On occasions, characters explain to Reacher things that he already knew, for benefit of the readers. It is justified, however, as the author always points out that Reacher lets them talk out of politeness, or to make them underestimate him.
* AuthorCatchphrase: "Reacher said nothing." Seriously, Child has got that macroed.
** Also, "That's for damn sure."
** And "Not good. Not good at all."
* {{Badass}}: Reacher is badass incarnate.
** BadassAdorable: In 61 Hours, it is revealed that decades ago, the US Army ran an experiment on Army brats to try to identify children who did not have a typical fear response. A monster movie was screened on military bases with a secret camera hooked up to capture the children in the audience precisely 18 frames after the monster makes its first appearance. The only one they captured without a fear response? [[spoiler:6-year old Reacher. Lunging TOWARDS the screen. With a switchblade. Which he managed to deploy in 3/4 of a second.]]
* BadassBoast: Reacher spits these out by the truckload in the movie.
--> '''Gary''': Well, I need to see something.
--> '''Reacher''': How about the inside of an ambulance?
* BallisticDiscount: Reacher has robbed illicit arms dealers more than once. Why do they not expect this? Who knows.
* BadassDriver: While he's described as an average driver in the novels, he's quite the driver in the film (in which all the stunts were done by TomCruise).
* TheBigGuy: Reacher stands at 6ft'5, and is built like a brick wall.
** PintsizedPowerhouse: On the other hand, he's played by the short TomCruise in the film version of ''One Shot''.
* BusmansHoliday: In his never ending sightseeing journey of USA, Reacher stumbles into more than a few conspiracies and criminals. HilarityEnsues.
* CombatPragmatist: Reacher, most prominently. [[EyeScream Eye gouging]], throat slitting, GroinAttack, etc., anything to kill his enemies quickly.
* ContrivedCoincidence: In ''The Killing Floor'', Reacher just happens to wander into the town [[spoiler:his brother was very recently murdered in]].
** The Affair tries to justify this with messages back and forth to his brother in that town, and about Blind Blake. Then Reacher takes his mustering out.
** Averted in ''Worth Dying For''. [[spoiler: Eleanor Duncan]] calls the police with evidence of all the crimes going on, but because [[spoiler: she admits that her husband constantly beats her, they think she's just making things up to get back at him.]] Thing is, she actually did get at least one cop's attention, and so when Reacher catches a lift, he ends up getting dropped off in exactly the right place for him to start setting things to rights.
* {{Determinator}}
* DidNotGetTheGirl: At least occasionally. For example, [[spoiler:in ''Die Trying'', while Reacher and Holly Johnson have a clear attraction and at one point engage in GladToBeAliveSex, she is in love with someone else and moves in with (and probably marries) him at the end of the novel. Reacher himself [[IWantMyBelovedToBeHappy just wants her to be happy]], though he’s more than a little disappointed about it.]]
** [[spoiler:At least she makes it out of the novel alive, unlike Secret Service agent/love interest M.E. Froelich in ''Without Fail'', who not only takes a bullet protecting the Vice-President-elect but expires in Reacher's arms afterwards.]]
** [[spoiler: While it's a stretch to call her a love interest, Reacher is attracted to Special Agent Sorrenson in ''A Wanted Man''. However, she gets shot to death as well. Reacher was already planning to storm the enemy's stronghold before her death, but its safe to say his subsequent massacre of the baddies is something of a RoaringRampageOfRevenge.]]
** Reacher ends up hooking up with [[spoiler: Vaughn from ''Nothing To Lose'', but it goes nowhere, because she's married, her husband's a vegetable]] and she only hooked up with him because they both knew that Reacher wouldn't be sticking around for long.
* DistaffCounterpart: Holly Johnson in ''Die Trying'', an FBI agent who also grew up on an army base, has gotten a lot of prestige considering her age, and kicks no small amount of ass herself despite one of her knees being torn up. She even spends a while thinking of Reacher as a bystander whose safety she's responsible for, before she finds out just how well he can handle himself.
* DomesticAbuse: ''Echo Burning.''
* DramaticGunCock: Deconstructed in ''The Affair," when Reacher debates the advantage gained from the intimidation factor of cocking his shot gun versus the disadvantage of having one fewer shell in the gun if it comes to a shoot out.
* EarlyInstallmentWeirdness: in the first book, ''Killing Floor'', and to some extent in the second, ''Die Trying'', Reacher has actual feelings and vulnerabilities. He sings and dances at various points, not quite activities Jack Reacher classic can be imagined doing. His competence level is not quite so superheroic as in later books, either.
* ExtremeDoormat: Most of the Duncans' neighbors in ''Worth Dying For'' fall into this trope, especially the motel owner and the doctor. They spend most of the book doing whatever Reacher or the Duncans want them to.
* EyeScream: Twice, and only in the ''first'' novel.
* {{Foreshadowing}}: Reacher mentions in ''Killing Floor'' that the guy who runs the shop he gets coffee at gives him coins in change because he doesn't have any one-dollar bills. [[spoiler: The local counterfeiters have been acquiring every one-dollar bill they can get their hands on to make one-hundred-dollar bills.]]
* GeniusBruiser: Reacher is usually portrayed as this.
* GirlOfTheWeek: Each book tends to have Reacher teaming up with a young, attractive woman, who he inevitably sleeps with (although to Child's credit, a [[IncompatibleOrientation curveball]] is thrown once or twice).
** In the ''Jack Reacher'' movie, [[spoiler: Jack does NOT sleep with the GirlOfTheWeek, although there was a scene early on where she thought he was going to try.]]
** In ''A Wanted Man'' Reacher teams up with Special Agent Sorenson and [[spoiler: Special Agent Karen Delfuenso]]. He likes and admires them both and feels at least fleetingly attracted to Sorenson. [[spoiler: But the prospect of getting involved with either of them never comes up - as it were - and then Sorenson is killed in any case.]]
* GoodIsNotNice: Reacher is often portrayed like this.
* GuiltByCoincidence: The whole plot of ''Worth Dying For'' is set in motion when Seth Duncan's wife shows evidence of being a battered woman, and Reacher locates Duncan and breaks his nose in retaliation. It turns out that [[spoiler:Duncan ''does'' have a history of hitting his wife, and everyone in town knows it, but in this specific instance it was actually two criminal thugs pressuring Duncan who attacked her, not Duncan himself.]]
* HandicappedBadass: Holly Johnson in the second novel, Die Trying. Having to rely on crutches to walk around doesn't stop her from [[spoiler:escaping her holding cell and killing at least three guerilla fighters armed with guns.]]
* IcyBlueEyes: Of the "piercing and icy" variety.
* ImprobableAimingSkills: Forms part of a thread throughout the movie; Reacher notes that Barr is a decent sniper, but not good enough for the five kills. Reacher himself displays this when he dispatches [[spoiler: Emerson]], as on the Awesome page, though it's also established that he was a Wimbeldon Cup contender, albeit one with rusty skills. [[note]]The [[http://en.wikipedia.org/wiki/Wimbledon_Cup Wimbeldon Cup]] is a prestigious marksmanship competition, with many of the top shooters in the US military competing. Previous winners include Carlos Hathcock, founder of the USMC Scout Sniper school.[[/note]]
* ItsPersonal: Some of the cases he looks into directly involve things from his military days that leads to Reacher doing everything to kill the bad guy. The Killing Floor has the death of his brother, the deaths of the former members of his squad in ''Bad Luck and Trouble'', and sighting the bad guy he thought dead in the Persauder, and he was on his way to kill the fall guy in One Shot when he ran into the conspiracy set up by the Russian.
* KnightErrant: Jack Reacher is a great contemporary example. He roams the countryside (a good part of the US), saves damsels in distress (when he's not sleeping with them), and gives villains no quarter.
* LastNameBasis: He is known as Reacher, by everyone including his mother. One person managed to use this as a warning.
* MajorlyAwesome: According to the movie, Reacher was a Major in the US Army, before getting busted down to Captain, and working his way back up to Major, prior to mustering out.
* MinorCrimeRevealsMajorPlot: ''Worth Dying For'': One douchebag beating his wife -> [[spoiler: his entire family (minus his wife) smuggling women and girls from Thailand for the sex trade and for their own sick desires.]]
** ''Killing Floor'': The murder of [[spoiler: Reacher's brother]] -> [[spoiler: an international counterfeiting ring that kills anyone who gets remotely close to it.]]
* OrgyOfEvidence: In ''One Shot'', this is what the case against James Barr becomes. However, what makes Reacher suspicious is not the amount of evidence, but [[spoiler:that the investigative team thought to look for a clue that they had no reason to believe existed.]]
* TheProfiler: Reacher can track people by their patterns of behavior.
** Subverted in ''Bad Luck and Trouble'' when his former sergeant profiled him better than he profiled her and was waiting on him at the Denny's.
** There's one of these in ''The Visitor'' (''Running Blind'' in the U.S.). [[spoiler:Subverted when she turns out to be the killer; everything she said in the novel was to try to throw people off her trail.]]
* RatedMForManly
* RightWingMilitiaFanatic[=/=]CrazySurvivalist: The main villains of ''Die Trying''.
* RussianGuySuffersMost: Played straight in ''One Shot''.
* SerialKillingsSpecificTarget: In ''The Visitor'' (known as ''Running Blind'' in the States), Reacher is taken in by the FBI because he matches the criminal profile of a currently active serial killer, but cleared of suspicion almost immediately and forced to aid in the search of the real killer. [[spoiler:The twist in the end is that the killer was TheProfiler herself, whose real target was her stepsister. She had deliberately chosen the other victims so she could plausibly fabricate a profile pointing to someone with an entirely different kind of motivation.]]
* SaidBookism: ''Averted.'' Even the AuthorCatchphrase has the word "said" in it. You can find "said" after countless lines of dialogue, ranging from questions to back-and-forth conversations.
* SherlockScan: Reacher is pretty good at these, probably due to his wide range of experience as a former military policeman. More than one reviewer has described him as a sort of modern-day Sherlock Holmes.
* ShownTheirWork: While the books are not infallible, Child has strong knowledge of the military and its strategy, and lets you know it.
* SuperDetailedFightNarration: without exception. Every fight scene in the series will take at least three times as long to read out loud as it would take to occur.
* {{Superdickery}}: The beginning of ''Persuader.''
* SympatheticMurderer: One way to look at Reacher. Child himself seems to take this view, as he is quite blunt in interviews about the fact that Reacher's actions frequently qualify as murder, but they're also almost exclusively PayEvilUntoEvil moments because the [[AssholeVictim people he kills in cold blood tend to deserve it]].
* TemptingFate: The owner of the town of Despair in ''Nothing To Lose'' is so paranoid that somebody might discover his secrets that he gets the police to throw out any stranger who walks into the town on a trumped-up charge of vagrancy, even if they're just passing through or they want to get something to eat. This… ''really'' doesn't work on Reacher.
* TitleDrop[=/=]JustifiedTitle: Every novel in the series.
* TownWithADarkSecret: Margrave in ''Killing Floor''- the entire town looks perfect, every building is immaculate and everything's clean and shiny... and yet there's virtually nobody in town, and certainly not enough people to justify the amount that must have been spent on making the town look so good. [[spoiler: Because the local 'philanthropist' organisation is actually counterfeiting money and throwing it to everyone in the town to buy their silence.]]
** Despair in ''Nothing To Lose'', a company town that [[spoiler: has been processing uranium without protection, resulting in a lot of people dying from radiation poisoning, while unable to do anything about it because the guy who owns the town simply doesn't care.]]
* [[TropesAreTools Tropes Are Not Bad]]: [[TemptingFate There's no way]] a MartyStu could result in an enjoyable read for any reason besides SoBadItsGood. Right?
* VillainTeamUp: In ''Worth Dying For'', three criminal bosses each send some of their men to Nebraska to help the Duncans take down Reacher. Thanks to a combination of [[spoiler:PoorCommunicationKills and [[EnemyCivilWar all three factions having orders to eliminate the other two once Reacher is dead]], the team-up doesn't last very long.]]
* [[WhyWeAreBummedCommunismFell Why We're Bummed Communism Fell]]: The collapse of the Berlin Wall is a major plot point in ''The Enemy''. The cutbacks that followed in subsequent years are the implied reason Reacher left.
** Subverted - the actual reason is given in ''61 Hours''; [[spoiler:Reacher built up a case against a general who had been selling food supplies that should have gone to his troops in the Gulf. The general laughed at him and got his skull broken complete with a six month coma. Only the strength of the case saved Reacher from outright discharge, but his commanding days were over.]]
*** The Affair covers his early retirement and the fact that he killed a congressman and a commanding officer of a special forces team for the murder and cover up of three girls near a training facility for the army.
** In the movie, Reacher musters out after the US withdrawl from Iraq.
