Character arcs
How to read this page
Everything here covers books 1–6. Each character’s own page carries a ## Book N
section with chapter citations; this page is the summary you read when you want to
know where someone stands now, or what a reread should be watching for. Where a
later book overturns what an earlier one establishes, the change is stated and the
chapter that makes it is named.
The four who carry the books
Jackson Lamb starts as the joke the Service tells about itself — the fat man above the newsagent’s — and ends book 3 as the one figure in the house who consistently knows what is happening. What changes is not his competence but the reader’s estimate of it: the sloth is method, the cruelty is management, and the question each book asks is how much of his own staff he is willing to spend. Book 1 answers “some”; book 2 answers “one, and he does not warn him”; book 3 answers “all of them, but on his terms”.
Book 4 changes the question rather than the answer. Lamb is absent for the whole of C01 and ostensibly out buying drink when the shooting starts, and the two who die in his building are killed by an enemy he never sent them against. The spending is real and it is not his decision, which makes the book’s verdict gentler and worse: he cannot protect them, and the only thing he can do with a death is price it. The last chapter has him blackmail a First Desk into a ten-year payment for Marcus Longridge’s widow and then refuse a desk at the Park. Book 4 is also the first to give him a past he did not choose: in C13 he says some of his own actions were done on David Cartwright’s orders, which makes him the O.B.’s man before he is anybody’s boss. Book 4’s answer to how much of his staff he will spend is “two, and he is not the one who spends them”.
Book 5 changes the question again: not who to spend, but how to stop anyone else spending them. He has no new staff to lose and loses none — every death in the book is outside the house. What he spends instead is the Service’s own receipt, the declassified Watering Hole Paper, handed to Diana Taverner in exchange for his people and Molly Doran’s pension (C14). Book 5’s answer is “none, and he makes the Service pay the bill”, which is either the moral high point of the series or its most successful piece of blackmail. It is also the first book in which he refuses a cover-up: C08 has him tell Catherine he will not invent a story, and ask Devon Welles to invent one that gets him into the Park.
Book 6 gives the question its ugliest answer and then declines to rule on it. He keeps River Cartwright in place as bait — C04 has him tell Catherine Standish that dangling River will bring Harkness out, and C08 sends the house’s field team west on the same reasoning. Two people do not come back: JK Coe, who was on the staff, and Emma Flyte, who had refused the posting in C01 and worked for the house anyway. He is not in Wales for any of it. He is in London, in C14, turning Martin Kreutzmer through a name Wicinski had run and a record keeper’s memory, and the message he sends through Kreutzmer returns as a newspaper paragraph from Poitiers: Anton Moser shot Frank Harkness in a parked car. Book 5’s Lamb bought his people’s paperwork; book 6’s Lamb ends with the paperwork gone — Ho finds every Slough House record erased in C14’s last pages — and meets Catherine’s accusation (“They’d still be alive if you hadn’t gone after Harkness”) with silence. How much of his staff he will spend is now “two, and he picked the fight that spent them”.
River Cartwright is the series’ ambition and its instrument. He spends book 1 trying to get back to the Park by solving a case nobody wants solved, book 2 being sent into the field as bait without being told, and book 3 walking into the Park on a stranger’s errand and being arrested for it. He is braver and more capable at the end of each book and further from what he wanted at the start.
Book 4 is where he stops asking to be let back in and starts working as what the Service calls a joe in the field. He shoots a corpse in the face to hide a missing mole, takes the dead man’s passport, and goes to France on it — a decision the book dates precisely as the moment he stops being an ordinary slow horse. What he finds there is that his family is the Service’s original sin: Frank Harkness is his father, Bertrand was his half-brother, and his grandfather bought Harkness’s absence with the money that funded Les Arbres. The book ends with him refusing Harkness’s offer of a place in the network and trying to arrest him instead, which is the first time in four novels he is offered somewhere else to go and turns it down. Nobody offers him a route back; the desk Whelan dangles at the end is offered to Lamb.
Book 5 makes him a watcher rather than an instrument, and its quietest development is that he has stopped asking to be let in. C13 has him admit to Louisa that he had been planning to quit, and the book does not send him to Abbotsfield: Shirley Dander and JK Coe go instead. His father is mentioned once, as a renegade with blood on his hands whom River might kill if the chance came (C10), and the series leaves the question of whether he would.
Book 6 takes the death he was sitting beside and then hands him the plot. His grandfather dies at Skylarks while he dozes (C01); the funeral at St Leonard’s in C03 is where Frank Harkness turns up, first as a figure under a tree and then as the man River vaults a grave to reach and is thrown off by. C12 gives him the meeting the series has been holding back: the cliff path, the offer of work and money a second time, the Glock over the edge, the shot in Frank’s boot, and a fight that ends with one figure standing — C13 confirms it was River, and has him walk inland to find Coe dead. He survives the book with none of what he asked for at the start of the series. C14 leaves him angry that his father got away, on the telephone to his mother, looking at JK Coe’s empty desk, and nobody has offered him the Park in two books.
Catherine Standish is the series’ conscience and its cost account. Book 1 gives her the discovery that the man she worked for was killed by the man she now works for; book 2 makes her the researcher who names Andrei Chernitsky and dates the Upshott arrivals; book 3 locks her in a farmhouse attic for a week, where refusing the wine is the action, and ends with her resigning on a motorway hard shoulder. The arc is not recovery — it is the withdrawal of consent.
Book 4 opens by establishing that the withdrawal never took effect. She has sent the same letter to HR three times, her discharge papers are still sitting unsigned on Moira Tregorian’s desk, and she is drawing a salary, which is the jurisdiction Emma Flyte uses to interview her. What she does with the time is harbour David Cartwright — in her bedroom, then at her neighbour’s, then at Slough House — and then ask the one question nobody else asks, whether shooting a bound prisoner is an op or an execution. She gets her answer when JK Coe takes the gun out of Shirley Dander’s hand and fires three times. The book closes with Lamb asking whether she is coming back and Catherine not answering. That is a more honest ending than book 3’s: consent withdrawn on a motorway lay-by turns out to be a form that needs somebody’s signature.
Book 5 makes her the house’s memory and its conscience in the same week. She lists Lamb’s failings to his face — unarmed desk officers sent out, the Park left uninformed, a Dog cuffed to a chair (C08) — and then makes the tea; she tells the room to go home (C13). And the series’ oldest question is finally put to her directly: C13 ends with Taverner asking whether Lamb ever told her how Charles Partner really died. Book 1 established it and four books have left it lying there; book 5 has somebody say it out loud.
Book 6 answers the question and then does something the series has not done before: it lets her stop drinking on the page. C06 has Lamb let himself into her flat, sit down among the bottles she has been buying and not opening, and tell her how Partner died — his own slip over a Stasi officer called Bogart, one syllable sold, three women hanged with piano wire, and his report of it to David Cartwright. He opens no bottle and leaves her with it. What follows is the arc’s real turn, and it is slow: she is buying a bottle a night in C01 and drinking tap water while he talks in C06; she finds Lech Wicinski in the wheelie bin and wipes the letters out of his face herself (C10), then argues with Lamb about who fitted him up (C11); and in C14 she arrives at the office having poured every bottle into her bath over the weekend. Her last scene is the book’s conscience doing its job — she names Coe and Flyte, says they would be alive if Lamb had not gone after Harkness, and leaves him in the dark. It is the Monday nine days after Coe was killed (C14), and the woman who would not take a drink in an attic in book 3 ends by emptying her own flat.
Louisa Guy begins as the competent one with no way back in and becomes the series’ soldier. She is seconded to Regent’s Park’s Russian assignment in book 2, keeps working it after Min Harper’s death, and in book 3 shoots three men to recover River Cartwright. She also takes a diamond out of a wrecked diamond merchant’s suite in book 2, which the series has not yet cashed.
Book 4 cashes it in its second chapter without making a scene of it: the stone went to a jeweller’s appraiser near Hatton Garden for cash, and the flat she describes in C01 is what it bought. The series’ longest-running debt becomes a mortgage between books and is mentioned once, over a pint. The same book makes her the rescue. She chases Patrice through the backstreets of South London, has her ankles beaten with a crowbar, and dives into the Thames after River, then tells him to pick up a phone in future. She kills nobody in book 4 — the killing is done by Coe — and she ends it with the man she worked beside in the ground, a flat and no promotion, which is as close as the series has come to saying what the job costs the one person doing it properly.
Book 5 gives her no killing and no rescue. She spends it watching a library meeting in Birmingham and opening the wrong drawer. What she does that matters is doubt: she doubts the attempt on Ho and she doubts Shirley’s account of the van (C08), and the book has her wrong about Kim Park and right about the van. She ends the fifth book still employed, still the competent one, and on the wrong side of the country when the shooting starts.
Book 6 is the first to send her out alone and make the solitude the danger. She takes leave in C04 to look for Min Harper’s son Lucas Harper, telling Catherine only that she needs time to herself, has Roderick Ho trace the boy’s Fitbit (C06), drives into Wales through the snow, and is the woman Frank Harkness briefs his crew to kill if she appears (C07). What the book gives her instead of a rescue is a costume and an empty pocket. C12 has her propose swapping coats with Emma Flyte; C13 has her find her own white ski jacket on the ground before she can see the body under it, lose Lucas in the same half-minute, and then front Harkness on the High Street by tapping a breast pocket she has nothing in — and he nods and walks away. Her only weapon in the book is a monkey wrench and her only bluff is a lie about a pocket. She ends the book offstage, having spoken to Lucas and to his mother, telling River she is fine and carrying both deaths as her own fault (C14). The competence the series has spent five books under-rewarding is finally the reason somebody lives, and the bill is Emma’s.
The Park
Diana Taverner is the series’ true protagonist in the institutional sense: book 1 ends with her holding the Fiasco file; book 2 has her buy Lamb’s Cotswolds operation and let Webb’s Russian approach stand; book 3 reveals she arranged Alison Dunn’s death years earlier and framed Donovan for it, and ends with her expecting First Desk after trading a Home Secretary’s favour. Each book makes her more powerful and more exposed.
Book 4 gives her something better than First Desk: a First Desk she can steer. Claude Whelan is in his first week, self-regarding and signable, and she spends the book managing him — lying to him at his first COBRA, then making him complicit by pointing out that he signed the warrant holding Giti Rahman before he briefed the Prime Minister, then working him into a shoot-to-kill order against River. She wanted Harkness shot rather than taken, and by the end she is still in post and still countersigning Whelan’s decisions.
Book 5 pays her the thing she has wanted since book 1. She runs the lockdown, the interrogation and the cover-up, tells Dodie Gimball what to print, tells Whelan the crew must die (C10, C11), and in C14 walks out of Lamb’s office with First Desk. It arrives as a trade rather than a promotion: Lamb gives her the Watering Hole Paper, proves it was declassified, and takes his people and Molly Doran’s pension in exchange. The series’ most patient operator finally gets the desk, and the book is careful to show what it cost — the office inherited from the First Desk she had spent two books steering, on the day she ordered a massacre covered up.
Book 6 is her first as First Desk and the first in which the desk is not enough. C01 has her reappraise Emma Flyte and offer her Slough House; C08 has her take Oliver Nash onto the Park roof to ask for the Fugue Protocol, a home-soil operation with no oversight, and be refused because she will not supply the grounds he requires; C10 has her read the application over anyway, knowing it failed, because the attempt is what gets minuted. The same chapter has her take a delayed go-dark notice from a civilian mobile in Pembrokeshire and tell Josie to file it under forget. Then C14 has Peter Judd offer her a Service funded by private partners and independent of government, with himself as broker, and she calls it a coup and leaves without another word. Her first book in charge is mostly refusals, and the one deal left on the table is the one she will not take — which is a more interesting position for her than the ambition of books 1–5 ever allowed.
Ingrid Tearney moves the other way. First Desk in books 1–3, she is boxed in by Judd in book 3, agrees to close Slough House to buy time, and expects to be retired — the one senior figure in the first three books whose fall is caused by an audit rather than a bullet. Book 4 confirms the retirement in a subordinate clause — she is “out the door” (C02) — and supplies the reason the Dogs were reorganised: she had used them as a private army (C03). Her fall happens between books and off the page, which is how the Service prefers its falls.
Peter Judd is the constant: Home Secretary by book 3, always buying influence with other people’s violence, always untouched. His fixer Seb dies in Lamb’s doorway at the end of book 3 and Judd’s path to Number Ten is unaffected.
Book 4 does not use him at all. He is named once, in C03’s list of changes at the top, as a former Home Secretary retired into private life. The political pressure in book 4 comes from COBRA and from a Prime Minister who asks the questions Whelan cannot answer, which is a different kind of pressure: nobody in the room is building a career on the bomb. Judd is still untouched, and book 4 keeps him untouched by leaving him out.
Book 5 puts him back in the margins and changes his position. He is not the Brexit campaigner — that is Dennis Gimball — and no longer Home Secretary, but a big beast “waiting out a hiccup in his career” and plotting a comeback (C06). Two mentions, no scenes: the series’ most durable politician is now defined by how little he has to do.
Book 6 gives him the scenes back and makes him worse. C07 has him meet Diana Taverner for lunch at a members-only club and hand her a warning — some rather bad people are about to commit naughty deeds on her patch — which turns out to be his own referral: a catering boy who saw something at Caerwyss Hall tried to extort fifty thousand pounds, and Judd passed the problem to a nation state, which sent Frank Harkness and his crew. C11 has Lucas name a former Home Secretary among the five men who tied a girl to a target, and Judd is the former Home Secretary the book has already put behind the hall’s PR firm. C14 gives him the pitch he has been building towards since book 3: a Service funded by private partners, acting without government approval, with himself as broker. Taverner calls it a coup and walks out. He is still untouched, and now he is not even pretending otherwise.
James Webb is the cautionary case. “Spider” spends book 1 as the man who ruined River’s career, book 2 as the officer whose Russian summit gets people killed, and book 3 in a vegetative state while the Park decides whether to switch the machines off. Book 4 does not mention him; the series has still not said what was decided.
Book 6 is the first to put him in the past tense. C05 calls him a “late Service officer” and Taverner’s earlier favourite, which is as close as the series has come to saying the machines were switched off. The inference rests on one word, and no chapter stages the death — the same reticence the series used for Duffy and for Tearney, and the reason book 6 can still refer to him without settling anything.
Nick Duffy and the Dogs are the Service’s willingness to do the ugly thing without asking; Molly Doran and Records are its memory, and the only department Lamb treats with something like respect. Book 4 replaces Duffy without announcing it. He is absent, brain-damaged since book 3; Sam Chapman — the Head Dog before him, sacked over money — is working as a private investigator and dies helping the house that sacked him; and Emma Flyte, eleven years in the Met and two months in the job, runs the section and insists it is not a private army. The line is meant, and the book then has her detain an analyst on a warrant nobody read. Records is what actually cracks the case: Shirley’s bet with Doran produces the Cartwright travel claims, the Henry file and Chapman’s name.
Book 5 gives Records its best turn in the first five books. Molly Doran is being let go (C08), and the original Watering Hole Paper is in her archive with the paper trail proving it was declassified (C14). The department the Service is disposing of is the one that saves it, and the pension Lamb negotiates for her is the only thing in the book he asks for himself. It is not her last appearance either: book 6 C06 has Lamb name her as the person who could say where the officer destroyed by Partner’s leak ended up, and C14 has him find Martin Kreutzmer through her memory and her files. The record keeper the Service was letting go is the one who identifies the mole.
Book 6 also closes Emma Flyte’s arc, and it does it in three moves. C01 has Diana Taverner offer her the sideways move the series has been threatening since book 4 — Slough House — and Flyte refuses it to her face, which ends her time in the Dogs; by C03 she is out of the Service and looking for work. What she does with the unemployment is the book’s judgement on her: she traces a missing boy for Louisa Guy off the books (C05, C06), wakes River Cartwright at six with the trace that starts the rescue (C08), and goes to Wales. C12 stages her capture and a small sound rather than a shooting; C13 finds the body under Louisa’s own coat, one chest wound; C14 records that her resignation was put down to personal problems and her death to gang violence. She never joins Slough House. She does its work anyway, and the Service files her under neither.
The other side
Frank Harkness is the series’ only antagonist who is also a family, and book 6 spends him. C03 has him attend David Cartwright’s funeral on false CIA paper, photograph the Service’s senior figures and drop a cigarette into the open grave, then drive off with River Cartwright on the bonnet; C07 has him brief three contractors to kill a woman from Slough House and make it look accidental; C12 puts him on a cliff path with his son, where he offers work and money for the second time, takes a bullet in the boot and goes over the edge. He comes back up in C13 with a gashed head and a stick taken from a kissing gate, follows Louisa and Lucas into town, and is turned away by a bluff — which is the last thing in the book he is shown doing. His death is a newspaper paragraph in C14: a body in a parked car in Poitiers, one bullet to the head. Lamb’s account makes it a purchase rather than a killing, since the message he sent through Kreutzmer reached Anton Moser. Reported, not staged — and that distinction is the whole point of the book’s last chapter.
His crew is the house’s mirror image. Anton Moser, Lars Becker and Cyril Dupont are three men on a contract, brought in through the referral Peter Judd made and paid to keep a boy quiet. Dupont’s throat is cut at the barn; Becker covers Emma Flyte’s body with snow and branches in the wood, then burns the barn with Dupont’s body and Coe’s in it; Moser is bought by the man he was hired to work against. Nobody gives them a pension, and nobody keeps their records.
The intake
Book 1’s house is River, Louisa, Roderick Ho, Sid Baker, Min Harper and Catherine, with Jed Moody passing through and Kay White and Struan Loy in the background. Book 2 adds Marcus Longridge and Shirley Dander and kills Min. Book 3 adds no one and sacks Marcus and Shirley mid-operation, which turns out to be a goad rather than a dismissal. Book 4 adds Moira Tregorian and JK Coe and loses Marcus and Sam Chapman.
Tregorian arrives as Catherine’s replacement — one in, one out, as River puts it in C01 — and turns out to have been sent by Whelan as one of his first acts in charge, which Lamb finds interesting and which C15 explains as sidelining a possible witness. She spends the book excavating Catherine’s paperwork, is interrogated over lunch, is displaced from her own desk by David Cartwright, faints during the attack, and leaves retiring on medical grounds. Coe has been in the house two months, came from Psych Eval by way of Molly Doran, shares River’s office, says almost nothing, and is the most dangerous person in the building: he puts a knife under Shirley’s chin for touching him and shoots a bound prisoner three times when she hands him the gun.
The staffing pattern is the point: the house replaces losses with people who have already been written off elsewhere. Book 4 sharpens it. The two who die are the pair the house had been using as its field team, and the two who arrive are a records clerk and a man from Psych Eval. The house is not reinforced; it is restocked.
Book 5 adds nobody to it. Coe becomes a fixture, Ho becomes the centre of the plot rather than its comic relief, and the only new arrivals are at the Park — Josie in the outer office, Devon Welles in the Dogs. The restocking pattern goes untested: no one in the house dies, and the two who come closest, Shirley and Coe, are the two the book sends to Derbyshire.
Book 6 restocks once and then stops. Lech Wicinski arrives from the Hub with his Service record already deleted and an accusation already attached, which makes him the intake’s first member whose file does not exist before he reaches the building; he is beaten and carved in the house’s own backyard (C09–C11) and survives it. Against that, the book kills two people who were doing the house’s work — Coe, who was on the staff, and Flyte, who had refused the posting — and replaces neither. By C14 there is no record that anyone ever worked there at all. The pattern that has restocked the house in every book so far ends this one with nothing left to restock it from.
Roderick Ho is the book’s engine and gets nothing for it. He lifts the number plate off four months of Hampstead footage with a bandaged hand (C04), runs the Fitbit trace twice (C06, C08), traces Wicinski’s pub meeting to Richard Pynne (C11), and in C14 — looking for Wicinski’s own erased record — discovers that every Slough House record has been erased. The man who treats people as accounts with permissions spends a book being the one who can still read the ledger, and ends it holding a database the house has been deleted from.
Shirley Dander is refused the death she has been running towards. Book 6 gives her Roderick Ho’s car and takes it away again — C12 puts it in a snowdrift, has her walk out and up the hill with the last of her speed in her, arguing with Marcus Longridge in her head and overruling him — and then sends her at a barn with a plank, expecting gunmen, into a cowshed where a woman in wellies offers her toast. C14 leaves her behind a frozen screen thinking she was not ready to die, which is the first time the series has let her say it.
JK Coe’s arc ends in Wales, off the page and in the past tense. C10 has him read the map and propose the barn search; C12 has him meet Cyril Dupont on the hillside, place him from the ferry-terminal watchlist, and reach for his blade as Cyril suggests they get on with it; C13 has River Cartwright find him sitting against a tree with his hands folded over a stomach wound and a knife on the ground. The killing is never staged — one chapter stops, the next reports — and he is burned with the barn before anyone outside the house knows. What the series gives him instead of a scene is an empty desk by the window (C14), and a sandwich Shirley had bought for him.

Survivors carry damage rather than wounds: Webb in a coma, Duffy with “limited brain function”, Catherine out of the Service and still on the payroll, Louisa with a mortgage bought with a diamond and the colleague she worked beside buried. Book 4 adds two more kinds of survival. Shirley does not manage her anger any more; the coda has her out dancing, deliberately cultivating it, because a managed anger is one somebody else controls. And River survives with a father, an identity built for him before he was born, and nothing to do with either.
Book 5’s survivors carry less visible damage. Shirley ends it with a torn ear, an unused gun and a gunman she talks into handing over his weapon instead of shooting him. Kim Park is held without charge. Whelan ends it without the desk he began it with. And Ho, who spends the book being shot at, ends it fed pizza in a room and still boasting.
Book 6’s survivors are the first who have to live with the arithmetic. Catherine is sober and has poured her flat away. Louisa has spoken to Lucas and to his mother, and blames herself for Emma. Shirley sat behind a frozen screen and understood she was not ready to die. River has a father killed by a subcontractor, which spares him the answer to book 5’s question, and an empty desk by the window. Wicinski has a face that will not stop explaining itself. And Ho has the discovery that there is no record that any of them worked there — which is the book’s last image, and the coldest kind of survival the series has offered.
Book 4 is also the first in the series to kill a slow horse for a reason that has nothing to do with competence: Marcus is at his desk after hours because he has a gun he means to sell. The two deaths are staged asymmetrically — Chapman dies on the page, in Patrice’s section, throwing a chair; Marcus is found — and that asymmetry is the book’s judgement on which death belongs to the plot and which to the man.
What the arcs have in common
Every arc in these books is a trade between competence and belonging. The people who are good at the job are the ones the institution spends — Min, Sid, Donovan, Traynor, Douglas, Louisa’s three kills, Marcus and Chapman — and the people who survive are the ones who stop asking to be let back in. Lamb’s protection is real and it is also the mechanism by which his people get used; the series has not yet decided whether that is fatherhood or farming. Book 6 breaks that rule cleanly for the first time: Coe asked for nothing and dies at a barn, and Flyte refused the job outright and dies doing its work anyway. What keeps a person alive in the sixth book is not resignation but who is standing where when the shooting starts, which is a less flattering law than the first five books proposed.
Book 4 supplies the missing term: the trade is hereditary. River’s competence is his grandfather’s, his father is the man who raised the bomb, and the Service’s protection of David Cartwright is the same bargain as Lamb’s protection of his staff, made twenty-odd years earlier and paid off in instalments. Fatherhood and farming turn out to be one arrangement seen from opposite ends. Harkness raises children to be assets; Cartwright raises a grandson and buys a man’s absence; Lamb raises nobody and prices the ones he loses. The last transaction in the book is a pension rather than a revenge, and that is the series’ most exact statement of what an institution has to offer its dead.
Book 5 adds the trade the series has been circling: an institution trading on its own paperwork. The document that makes the operation possible is British, declassified by the man Catherine worked for, and written by the First Desk trying to survive it; nobody is prosecuted and it becomes currency. The arcs’ common term — competence spent by belonging — turns out to apply to the Service itself. It spends its own history to keep four people employed, and the book calls that a rescue because there is no other word available.
Book 6 supplies the term the trade has been missing, and it is the record. The house loses two people in one operation for the first time — Coe, who was on the staff, and Flyte, who was not — and the book tells the reader they are dead before it gets there: the prologue walks away from a burning barn in Wales with a man’s and a woman’s body behind it, and names neither of them, so the identification has to wait for C13. That is a different trick from book 5’s Joon, whose death is already in the past when the book opens; here the reader is told the outcome and then made to watch the house work towards it, which is the same asymmetry book 4 used on Marcus and Chapman, run in the opposite direction.
The payment is not a pension either. Lamb finds the man behind the fit-up through a name Wicinski had run and a memory Molly Doran still keeps, buys one of Harkness’s gunmen, and the book’s last pages report that every Slough House file has been erased (C14). Book 5 had the institution trading its own paperwork to keep four people employed; book 6 has the paperwork taken away and leaves them turning up anyway. The series has been asking since book 1 whether a department is a building, a file or a person.
