At the time Lee Child sat down to write his first novel Killing Floor, he was unemployed, having been fired from his position as a presentation director for Granada Television. According to Child, this was a purely pragmatic decision: "I wasn't one of these people that felt compelled to write. It had to keep a roof over our heads, so it was totally, totally 110% commercially motivated."
Critics have perceived other influences in Jack Reacher's creation. Bob Cornwell quotes Lee Child's reply in another interview as having created Reacher "as an antidote, to all the depressed and miserable alcoholics that increasingly peopled the genre".
The character's name first came to Child in a supermarket when an old lady, noting the span of Child's arms, asked for his help in reaching out to a can of pears. On seeing this, Child's wife commented that if his writing career did not work out he could "always get a job as a reacher in a supermarket". Reacher's ex-military background was a specific and tactical choice on his behalf. Child has explained, "I thought that I would do a book that's not the same as everybody else's. Everybody else had their guy working: a private guy in Boston or a police lieutenant in L.A., or wherever. I thought, 'Well, he won't be working, and he won't live anywhere, and let's just take it from there.'" Child also felt that this origin would lend itself to the character's personality and nomadic lifestyle: "This idea of the rootless alienation has got to come from somewhere, and I noticed that the most alienated people are always ex-military, because it’s like going from one solar system to the other, it’s so different. So that was an easy choice: Make him ex-military. Then make him ex-military police because, broadly speaking, these would be crime novels, and he had to have some investigative experience, and he had to understand procedures and forensics and so on. So that part was all set in stone".
Numerous critics have pointed out the various similarities between Lee Child and Jack Reacher. Bryan Curtis, writing for Grantland, and Natasha Harding and Caroline Iggulden, in a separate article for The Sun, have brought out the various similarities between Child and Reacher: Child is 6 ft 4 in (1.93 m) tall while his protagonist stands at a similar 6 ft 5 in (1.96 m); both writer and creation consume "incessant amounts of coffee"; Child "lives in cheap pairs of jeans and T-shirts and says the idea of buying expensive clothes is “crazy” to him" (just like Reacher); and that "Jack Reacher’s famous physical qualities are based on Lee’s playground memories as a child". Child tends to agree with such observations: "I was huge as a kid and Reacher's stature is me translated as a kid. I enjoyed being bigger and fighting shamelessly. I've done a fair amount of headbutting. It's an awesome manoeuvre." Andy Martin notes that "just as Reacher is half-Rimbaud, half-Rambo, Child is both art-for-art's-sake Parnassian and ruthless businessman."
Curtis, as well as Harding and Iggulden, have also considered the role Child's dismissal from Granada had on Reacher's development. Harding and Iggulden note that as "A union rep who hated injustice, Lee poured his anger at his sacking into the character...who always wins against the bad guys." Curtis also notes that "Child created Reacher from the smoldering embers of his own rage. It might seem like a simplistic theory, but it’s true. Like the author, Reacher was workplace surplus: He was a military policeman in an era of Army downsizing. The act of leaving his job turned Reacher into a protective figure, an avenging angel." He finds that Reacher's actions are a manifestation of Child's anger at his sacking and that his violent ways of dealing with villains is 'cathartic' to the author.
Lee Child views Jack Reacher as a "happy-go-lucky guy. He has quirks and problems, but the thing is, he doesn't know he's got them. Hence, no tedious self-pity. He's smart and strong, an introvert, but any anguish he suffers is caused by others."
When asked about the casting of Tom Cruise in the role of Jack Reacher, Child replied that "Reacher’s size in the books is a metaphor for an unstoppable force".
He has also referred to Reacher on multiple occasions as a 'knight-errant' and in an interview for the Time magazine describes the character as: " (He’s) two things in one. On the surface, he is an ex-military cop who is suddenly dumped out into the civilian world. He doesn’t fit in, and he spends his time wandering America, seeing the things that he’s never had time to see before. He’s trying to stay out of trouble, but masterfully once a year getting into trouble. He’s also the descendant of a very ancient tradition: the noble loner, the knight errant, the mysterious stranger, who has shown up in stories forever… He is a truly universal character... I’m writing the modern iteration of a character who has existed for thousands of years."
In another interview for Esquire magazine, Child further analyses the mythology of his character:
The stories that I love are basically about the knight-errant, the mysterious stranger. And the reason why people think that's an essentially American paradigm is the Westerns. The Westerns were absolutely rock solid with that stuff. You know, the mysterious rider comes in off the range, sorts out the problem, and rides off into the sunset. It is just such a total paradigm, but not invented in America. That was imported from the medieval tales of Europe. The knight-errant: literally a knight, somehow banished and forced to wander the land doing good deeds. It's part of storytelling in every culture. Japan has it with the ronin myth; every culture has this Robin Hood idea. So really, that character was forced out of Europe as Europe became more densely populated and more civilized. That character no longer had stories in Europe; it had to migrate to where the frontier was still open and dangerous, which was America, essentially. So the character, I think, is actually universal and historic, most recently, normally represented in America. I think the Westerns saw it firmly adopted by America, so yeah, right now, we think of this as a completely American character, but really, it's more historic than that. But I'm very happy to have that reference made.
Child also views Reacher as "post-feminist" stating that he does not parlay in "gender distinction...Reacher likes strong, realistic women, and he treats women with respect...he doesn’t cut them any slack, but also he has no negative preconceptions. If you're a woman, he will be your friend; but if necessary, he will kill you (the woman)".
Jack Reacher is described as being a former major in the United States Military Police Corps.
Jack Reacher was born on a military base in Berlin, on 29 October 1960
Jack's mother Josephine Moutier Reacher (née Moutier) was a French national, both being fluent in French from early childhood but as Jack admits in The Affair (2011) he speaks the language Un peu, mais lentement ("A little, but slowly").
After being shunted around the world, growing up on U.S. military bases his father Stan was deployed to, he gained an education in basic survival as well as an opportunity to enter the United States Military Academy at West Point. After four years at West Point (1979 to 1983) Reacher achieved the ranks of 2nd Lieutenant, 1st Lieutenant, Captain, and Major including an intervening demotion from Major to Captain in 1990 during his tenure in the Military Police. During his 13 years of service, his achievements were recognised in the form of citations and awards including the Silver Star, the Defense Superior Service Medal, Legion of Merit, Soldier's Medal, Army Commendation Medal, Bronze Star, and a second Silver Star and Purple Heart for wounds sustained in the bombing of the U.S. Marine Corps barracks in Beirut in 1983.
While his Silver Star and Purple Heart are cited on his profile, all of the other medal citations involve official secrets and are therefore redacted. The short story Deep Down hints that he possibly was awarded the Legion of Merit as a result of exposing a female liaison officer who was leaking confidential information to the Soviet Union.
Reacher served in the Army's Military Police branch, resigning his commission and mustering out at the rank of Major. His unit, the fictional 110th Special Investigations Unit, was formed to handle exceptionally tough cases. He left the armed forces in 1997, partly due to a reduction in the forces and partly because he verbally offended a Lieutenant Colonel during an investigation in Mississippi, who then singled him out for discharge.
Among his formal qualifications, Reacher is described as the only non-Marine to win the Wimbledon Cup, a US Marine Corps 1000 Yard Invitational Rifle Competition; achieving a record score in 1988. Anecdotally his fitness reports rated him well above average in the classroom, excellent in the field, fluently bilingual in English and French, passable in Spanish, outstanding on all man-portable weaponry, and beyond outstanding at hand-to-hand combat. Reacher describes himself as a brawler, his fighting style likened to a thrown chainsaw with the motor running.
After leaving the Army, Reacher became a drifter, his only baggage a folding toothbrush, although after the September 11 attacks, with restrictions on wire transfers in the light of fraud he is obliged to carry an ATM card and photo ID in the form of a (generally expired) American passport.
Emily Sargent, while conducting an interview with Lee Child, describes Reacher's post-military life as follows:
You will never find Reacher going to the laundry or doing the ironing. When his clothes get dirty he simply goes to the local hardware store and buys a functional pair of chinos and a workman's shirt and stuffs the old ones in the bin. No mortgage, no wife, no ties, he is a perfectly free agent, unlimited and unbound, incapable of ever settling down.
Lee Child describes Reacher's obsession to wander about:
He's an ex-military policeman, and he was demobilized in his middle thirties after having served all of his adult life in the [U.S.] Army and having grown up on Marine bases, because his father was a Marine. The idea was to have a character that was plausibly rootless. Most people who are wanderers do it for other reasons—they are mentally ill, or something like that. Reacher is completely competent, but he's just habituated to this fragmented life in the military, so he can't settle into civilian society. The idea of staying anywhere for more than a few days is anathema to him.
Reacher himself expounds on a hypothesis about this vagrant life-style in Never Go Back. He states that he has a genetic disposition towards roaming about, citing the British Empire, the Vikings, and the Polynesians as groups with a similar wanderlust. While he accepts that there was an economical necessity behind their voyages, he maintains that "some of them could not stop". He feels that long ago when humans lived in small bands, there was a risk of inbreeding as a result of which a gene developed over the course of evolution such that "every generation and every small band had at least one person who had to wander". This would lead to "mixing up of gene pools" and would be "healthier all around". Reacher concludes:
I think ninety-nine of us grow up to love the campfire, and one grows up to hate it. Ninety-nine of us grow up to fear the howling wolf, and one grows up to envy it. And I'm that guy. Compelled to spread his DNA worldwide. Purely for the good of the species.
Reacher's large physique means his character is sometimes mistaken by other people. For example, in Die Trying, Reacher is wrongly suspected by the FBI of being involved in a kidnapping, which assesses him (solely on the basis of a few photos) as such: "The big guy is different. Different clothes, different stance, different physically. He could be foreign, at least partly, or maybe second generation. Fair hair and blue eyes, but there's something in his face. Maybe he's European, perhaps a European mercenary or terrorist." Reacher is aware of this, though. In Make Me Reacher gets off at a remote train station (for no reason other than he liked the name of the town, [Mothers Rest], and "he has no place to be & all the time in the world to get there.") he sees a woman coming out of the shadows with a look of expectation. He immediately understands that the person she was waiting for must be very tall (like him) as it's his standout feature on first meeting someone.
In Echo Burning, Reacher narrates how he first turned "his fear into aggression". He had been about four when he watched a television show on space adventures. One such episode depicted a space monster which had then terrified the young Reacher. After that he was unable to sleep for days on end, thinking the monster was under his bed and would get him if he tried to sleep. And then, according to Reacher, his younger self got mad: "Not at myself for being afraid, because as far as I was concerned the thing was totally real and I should be afraid. I got mad at the thing for making me afraid. For threatening me". Reacher then one night "kind of exploded with fury". In his words, Reacher "raced down the monster" and successfully changed his fear into fury. He also stated he has never been scared since.
This fact is later seconded when in Never Go Back, an Army psychological study of fear in children is cited that showed Reacher to have abnormally fast reflexes and aggression levels at the age of six; Reacher believes that this abnormal level of aggression at that age is not due to genetics (as the Army report suggested) but because he got tired of being frightened, and trained himself "to turn fear into aggression, automatically".
Reacher seldom shows remorse for the numerous felonies he perpetrates and has a primal sense of justice. In Personal, after killing a thug, he defends his actions to a distraught Casey Nice (his accomplice in the novel) by stating the man could have spent his life performing good deeds such as 'helping old ladies across the street', 'raising funds for Africa' or 'volunteering in the library'. Instead the man extorted money and hurt people and when he 'finally he opened the wrong door, what came out at him (his death) was his problem, not mine'.
This primitivity on part of Reacher is commented upon in Never Go Back, where Reacher is described by Susan Turner as being like "something feral....It's like you've been sanded down to nothing but yes and no, and you and them, and black and white, and live or die. You're like a predator. Cold and hard." (p. 176–177) However, when she witnesses Reacher's outrage at the hurt inflicted upon an innocent waitress, she reconsiders and states that he is actually not feral as she had earlier presumed. Furthermore, she notes that Reacher had till then attempted to solve only her problems, neglecting the problems of his own:
And you’ve done nothing but chip away at my problem. You’re ignoring your own, with the Big Dog. Which is just as serious. Therefore, you still care for others. Which means you can’t really be feral. I imagine caring for others is the first thing to go. And you still know right from wrong. Which all means you’re OK.
This underlying kindness perceived by Turner is visible in many of Reacher's actions: he stands up for the right of women in both Echo Burning (where his helping a woman escape from an abusive husband forms the main plot of the story) and in Worth Dying For (where he breaks the nose of an abusive husband for beating up his wife) and is sympathetic to those in need, as seen in The Hard Way where he bequeaths all of Edward Lane's fees paid to him for the medical treatment of a man Lane had betrayed many years back.
This point is further elucidated in Personal, when Reacher reminisces while standing at his mother's grave:
She (Reacher's mother) had said, 'You've got the strength of two normal boys. What are you going to do with it?'
I hadn't replied. Our silence was part of the ritual. She answered for me. She said, 'You’re going to do the right thing.'
Reacher is described as proficient in hand-to-hand combat. He is quite fast for his height, and often fights opponents his size or larger. His skill is attributed to the fact that he grew up all over the world, due to being in a Marine Corps family. While he is not a master in any one form of combat, he tends to incorporate moves from various styles. His favorite moves are headbutts, elbow strikes, and kicks to the groin.
Reacher generally goes with the flow of the fight, caring about winning more than how he wins. However, he plans out how to strike first or react to the first strike, and how he'll make sure the other person never fights him again.
Reacher has an internal clock. He sets a time to wake up at and his body automatically awakens. He often sets a timer in fights to try and get a tactical edge. Reacher also has a fascination with numbers. In "Bad Luck and Trouble", Reacher uses this to figure out his old co worker Neagely was signaling him, by giving him money in his bank account.
Reacher has extremely acute deduction skills. He generally gains his information simply from talking to people or making minute observations. He will pick up on a simple pause and relate it back to what he is trying figure out. He is known as one of the best investigators the Military Police Corps had to offer, and he led a special unit tasked with difficult cases.
Reacher is also described as skilled marksman, principally in One Shot, being the only non-Marine to win the US Marine Corps 1000 Yard Invitational rifle competition, he also won the US Army Pistol Championship and served as a pistol instructor.
The martial art Keysi (the Keysi Fighting Method) is used in one of the street fights in the feature film Jack Reacher
Reacher has a love for music, especially blues. It was this affinity that inspired Reacher to get off the bus at the start of Killing Floor, and in the same novel reveals that he has a music collection in his head, replaying tracks as he travels without needing the technology others seem to be obsessed with and burdened by. Reacher explains this to detectives investigating an early morning suicide on a near-deserted New York subway near a visit to a Blues club on Bleecker Street (Gone Tomorrow, Chapter 7).
Reacher espouses no personal religious beliefs but is generally accepting of the beliefs of others, though he is scathing in his dismissal of the town boss Thurman's fundamentalist Christian position in the novel Nothing to Lose: When asked if he is "born again" Reacher says "Once was enough for me" and later rhetorically asks Thurman "I'm here to visit the sick and you want to have me beaten up? What kind of Christian are you?" (Chapters 38 and 44). He also mentions at the opening of Bad Luck and Trouble (Chapter 4) that he avoids Alaska Airlines because "they put a scripture card on the meal trays".
Reacher is also critical of the corruption of traditional spelling, such as the use of contractions like "U" for "you", "lo" for "low", disliking the absence of the apostrophe in don't walk pedestrian before they were replaced, then noting he also disapproved of replacing words with pictures (Chapter 20).
While Reacher knows how to drive, in A Wanted Man he professes to be a bad driver, and in Bad Luck and Trouble he says he can't rent a car because he doesn't have a driver's license (Chapter 22). In Without Fail Agent Frolich trawls various databases for her UNSUB (Reacher) only to discover he is effectively untraceable, because without a driver's license she has no photograph and no address (Chapter 1).
His single indulgence - aside from casual sex - is coffee, which he drinks constantly, as admitted to in The Enemy:
[Joe] was probably the only other human on the planet who liked coffee as much as I did. He started drinking it when he was six. I copied him immediately. I was four. Neither of us has stopped since.The Reacher brothers’ need for caffeine makes heroin addiction look like an amusing little take-it-or-leave-it sideline.
Bryan Curtis, in an interview with Lee Child, describes Reacher thus:
His face looked like it had been chipped out of rock by a sculptor who had ability but not much time.
From A Wanted Man: "He was one of the largest men she had ever seen outside the NFL. He was extremely tall, and extremely broad, and long-armed, and long-legged. The lawn chair was regular size, but it looked tiny under him. It was bent and crushed out of shape. His knuckles were nearly touching the ground. His neck was thick and his hands were the size of dinner plates...A wild man. But not really. Underneath everything else seemed strangely civilized....His gaze was both wise and appealing, both friendly and bleak, both frank and utterly cynical."
Reacher is described as being 6 feet 5 inches (1.96 m) tall, weighing 210–250 pounds (95–113 kg) and having a 50-inch (130 cm) chest;. In Never Go Back, he was described as having "a six-pack like a cobbled city street, a chest like a suit of NFL armor, biceps like basketballs, and subcutaneous fat like a Kleenex tissue." In his youth, his physical appearance likened to that of a 'bulked-up greyhound'. He also reveals that his size is purely genetic; he states in Persuader and Never Go Back that he is not much of an exercise enthusiast.
He has various scars, most notably a collection of roughly stitched scars on his abdomen caused by a bombing in Lebanon, with ugly raised welts that are later instrumental in saving his life, a 3-to-4-inch-wide (8 to 10 cm) white scar that intersects his shrapnel scar that he received during a knife fight in Gone Tomorrow. Reacher attributes his survival to the rough MASH stitch work (Chapter 83).
He also has various other scars: one from a chest shot with a .38 Special. and a powder burn from a near-miss at point blank range, and one on his arm where his brother struck him with a chisel.
He suffers his first ever broken nose in "Worth Dying For", at over 50 years of age. He resets the bone with a thump from his palm and later puts on a plaster bandage made of duct tape.
Reacher's maternal grandfather, Laurent Moutier, was a furniture restorer in Paris, who, at thirty years of age, volunteered for the French Army in 1914 at the outbreak of World War I, fighting at Verdun and The Somme. Between 1919 and 1929 he was commissioned to produce wooden legs for wounded veterans. Josephine Moutier was his only child. He died in 1974 at age 90. Jack, as a boy, met him three times and is described as having liked him.
Reacher's mother, Josephine Moutier Reacher, born in France, was 30 years old when Reacher was born. She met Reacher's father in Korea and married him in the Netherlands. When she was only 13, she joined the French Resistance and under the alias "Beatrice" worked with Le Chemin de Fer Humain (the Human Railroad), saving 80 men. She garroted a schoolmate, a boy who threatened to give her up to the Nazis, and would later receive the Médaille de la Résistance (the Resistance Medal) for further heroism. She was widowed in 1988, and died in 1990 at the age of 60 of lung cancer. Reacher described his mother as "gallic, feminine, obstinate," and "[the] most stubborn woman possible." He also branded her a fatalist as she had concealed her cancer from her children and had refused treatment for a one-year period before her death. However Reacher compares her favourably to his father: "My father hadn't killed the enemy at the age of thirteen. But my mother had. She had lived through desperate times and she had stepped up and done what was necessary." Reacher also has great respect for his mother: at her funeral he buried his Silver Star medal with her, and on learning of her role in World War II, states that he became the man he was because of her.
Reacher's father, Stan Reacher, was a United States Marine Corps captain, who served in Korea and Vietnam. His military service kept his family continually moving all around the world to various military bases. At the time of the short story Second Son, when Jack was 13, he was stationed in Okinawa and involved in preparing contingency plans for an invasion of Mainland China. In the same short story, Stan Reacher is depicted as "a child of the depression," coming from a miserly New England family, and as a result was a proponent of the theories of "Waste not, want not," "Make do and mend," and "Don’t make an exhibition of oneself." Jack described his father as "a plain New Hampshire Yankee with an implacable horror of anything fancy...he had no use for wealth and excess. Very compartmentalized guy. Gentle, shy, sweet, loving man, but a stone-cold killer. Next to him I look like Liberace". Jack Reacher furthermore highlighted this dichotomy in his father's behaviour by stating that he would be engaging in violent actions such as "how to angle a claymore mine so the little ball bearings explode outward at exactly the right angle to rip the enemy's spines out of their backs with maximum efficiency" one day, and the next day would be doing something calmer, like "watching birds," After military service, "there was no place left for people like him." He died in 1988. James Stanfield, in an article concludes that "Reacher clearly looked up to and idolised his father, and though Reacher’s reasons for leaving the service were very different to his dad’s, they’ve ended up at the same point."
Jack had only one sibling, brother Joe Reacher, who was two years older than Jack. Physically, Joe was one inch taller 6 ft 6 in (1.98 m) and a "little slighter" than his younger sibling, weighing 220 pounds (100 kg). Joe was born on a military base in the Philippines, and Jack is described as helping Joe beat up the kids who gave him trouble in school, and vice versa. However Joe also had scuffles with his own brother, given the scar that Jack had put on his forehead during their childhood. Joe was also a West Point graduate, and spent five years in military intelligence, where he never won any of the "good medals", only the "junk awards." Jack attributed his brother as being pedantic, and called him a perfectionist, "a man horrified with anything less than the best." Joe is described as joining the US Treasury Department, and died at age 38 in the line of duty, having arranged a meeting with a potential investigation subject. Because he was killed in the line of duty, his name can be found on the Treasury Department's Roll of Honor.
Critics have noted the strong theme of "justice" pervading the character as well as the book series. Claire E. White, characterises the titular protagonist as: "wanderer, a hero who is a bit alienated from the establishment, but whose sense of justice is strong. He reminds (me) a bit of a character from the Old West: the strong, mysterious loner who never stays in town for long.". Mike Ripley detected the influence of Jack Schaefer's western novel Shane in the Reacher novel Echo Burning while Bob Cornwell calls the debut Jack Reacher novel Killing Floor "a classic western".Grantland columnist, Bryan Curtis calls the character "a protective figure, an avenging angel" and quotes the author Michael Connelly describing the Reacher book series as: "These are postmodern Westerns, they’re Shane. A stranger comes to town and sets things right. Then he leaves town." The critic Emily Sargent says of the fictional Reacher: "just the kind of no-nonsense, ramrod hero an intelligent five-year old would dream up: a strapping, broad-shouldered, idealised father-figure, something akin to God in his wisdom and power, alternately benevolent and overwhelmingly cruel, fair but firm. Good at saving damsels in distress and sorting out bad guys.".
Rick Gekoski, writing for The Guardian takes a similar if darker interpretation of the character: "Reacher is, of course, in a long line of American outcast heroes (how does the Coventry-born ex-TV-man author know so much about this?) who abjure emotional ties, head out into the wilderness and take upon their own broad shoulders the primitive moral conscience of the tribe. Too immature to make a sexual commitment, obsessed with death and terror, this archetypal hero of American fiction was first described in Leslie Fiedler's classic Love and Death in the American Novel (1960).". In the same article he also questions whether Fiedler would find that Reacher's hypermasculinity is a sign of the character's "repressed homosexuality".
Malcolm Gladwell, in an article for The New Yorker perceives a difference in the Reacher character and the traditional Western characters in terms of the symbolism they represent to the general public. In his opinion "The traditional Western was a fantasy about lawfulness: it was based on a longing for order among those who had been living without it for too long. The heroes conduct themselves according to strict rules of chivalry. They act— insofar as it is possible —with restraint. In the world we live in today, by contrast, we have too much order: we are, as we have been reminded so frequently lately, over-policed. Our contemporary fantasy is about lawlessness: about what would happen if the institutions of civility melted away and all we were left with was a hard-muscled, rangy guy who could do all the necessary calculations in his head to insure that the bad guy got what he had coming. That’s why there are rarely any police in Reacher novels—or judges or courts or lawyers or any discussion or consideration of the law. Nor is there any restraint on the part of the hero. He’s not pointing toward a more civilized tomorrow. He’s leading us back into the wilderness, with the reassurance that our psychopaths are bigger and stronger than the bad guys’ psychopaths."
Sargent also notes the dichotomy in Reacher's character, stating that he is intellectual and generous despite his exterior appearance of being "unkempt, unshaven and out of uniform, a loner, avenger, perpetual outsider at odds with the army". In Sargent's express opinion:
Curtis concurs, remarking that "Reacher isn’t just a mindless vigilante. He can also be a liberal do-gooder. He has expressed sympathy for gays in the military and undocumented immigrants. In Child’s latest book (at the time when this article was first published), A Wanted Man, Reacher worries that the Patriot Act will lead to all sorts of 'national security bullshit.' Child has invented a kind of progressive vigilantism. The scumbag is killed, but usually for the right reasons."
Multiple critics have pointed out that the Jack Reacher character is characterised by his spells of silence, with Curtis claiming "Reacher’s classic line is silence."
Others have been critical of the various implausibilities and contradictions present in the character and his behaviour. Notes The Washington Post journalist Kevin Nance: "The unlikelihoods and outright impossibilities stack up. Ever a frugal sort, Reacher travels mostly by hitchhiking (as he does at the beginning of “A Wanted Man” and 2001’s “Echo Burning,” both set roughly in the time they were written), even though the practice is roughly as current as bellbottoms and even though his appearance is, as previously established, notably simian. (Not that this deters a series of smart, attractive young women, most of them officers of the law, from jumping into bed with him.) And although he’s a loner who seems never so happy — rather like Agent Cooper in “Twin Peaks” — as when sitting quietly in a diner with a cup of black coffee and a piece of pie, he has an uncanny knack for stumbling into the worst kinds of trouble, almost none of it connected to himself."
Michael Cavacini has also noted the last implausibility mentioned by Nance, stating that unlike traditional whodunits, where a detective "simply solves a problem because it's his job", Reacher has no formal reason to be involved in anything and consequently "seems to always wind up in a situation where something goes wrong and he must make right".
Lee Child has described Reacher's accomplices and their characterisation and origin in the following terms: " The whole cast for each book is new. It kind of depends on what the scenario is and what the set up is. Do I use people that I actually know? In a way yeah, because you met people and you regard them as meta-typical as one thing or another – so as a large extent, yes, they are based on people I’ve met but not specific individuals."Jill Hemingway, exact age unknown, possibly in her thirties, was a suspended FBI agent operating freelance in New York during 1977. She had been investigating the criminal activities of a New York mobster, Croselli but her investigation had been shut down and she had been suspended, pending review as part of a deal cut by Croselli with the FBI. She had since tried to unsuccessfully bring Croselli down by getting him to boast of his crimes on tape. She admitted that bringing down Croselli had become somewhat of an obsession for her, stating "[Croselli] burns her up." Hemingway is described as a thin, pale, nervous, blonde woman and she teams up with a nearly seventeen year old Reacher in the novella High Heat to incriminate Croselli. She suffered from heart-related ailments and she died near the end of the story due to a heart attack after having accomplished her goal. Reacher described her death as: " She died young, but she had a smile on her face."
Elizabeth Deveraux, late thirties, is a former Marine serving as a county sheriff in Carter Crossing, Mississippi in 1997. She appears in The Affair, where she tacitly condones Reacher's highly illegal ways of getting rid of some unsavory characters. She was a potential lover for Reacher, as they had sex several times, but ended up drifting apart.
Karla Dixon, age unknown, possibly late 30s is a forensic accountant; formerly a Major in the Army and part of Reacher's 'Special Investigators Unit', which he formed and led in the 90s. They are reunited in Bad Luck & Trouble and secretly rekindle an affair, which they regret not starting back in the Army. She is described as 'dark, very pretty, comparatively small' and slim. She is extremely good with numbers and shares Reacher's fascination with mathematics.
General Leon Garber, retired, was Reacher's former commanding officer, mentor and close friend. His only child is Jodie. He risked his life to help Reacher in Die Trying, and willed him his house, as his daughter is wealthy, didn't want it and already owns her own New York City home.
