Magic is applied mathematics. The many-angled ones live at the bottom of the Mandelbrot set. Demonology is right after debugging in the dictionary.
—Bob Howard, "Pimpf"
A series of Cosmic Horror Story novels and novellas by author Charles Stross. According to Word of God, the idea for the series originated from a realization that Lovecraftianhorror and the Cold War are actually pretty darn similar, and if there really wereelder, tentacled horrors lurking around the edges of reality, the government would get involved and the departments they'd set up to do so would look very much like Stale Beer flavoredSpy Fiction.The main protagonist of the series is Bob Howard, a Desk Jockey who was forcibly recruited into "The Laundry" after his graduate computer science work nearly summoned Nyarlathotep. Now he's charged with protecting Earth from incursions by the many-angled ones, who can be summoned all too easily with modern computer technology. Most of the job is attending meetings and filling out paperwork, but ever so often there's a major incident that results in Laundry agents trying to fight off Cthulhu and his cronies with their Palm Pilotsnote Hey, the first novel was published in 2004 before smart phones were big; later novels depict Bob suitably upgrading to an iPhone, Monkey's Paw wards, and the occasional briefcase nuke, while Bob has the misfortune to land right in the middle of it.The series is thus far composed of the following novels and short stories (in chronological order):
The Atrocity Archive
"The Concrete Jungle" (published together with Archive as Archives, and available online)
The Armageddon Score (to be published in July 2015)
The Nightmare Stacks (to be published in 2016)
According to Word of God (on his blog), the series was planned in advance to be 9 books long (plus assorted side stories), with CASE NIGHTMARE GREEN beginning around book five or so. However, The Rhesus Chart was apparently not part of the original plan, thus probably extending the series by at least one book. (Updated Word of God: books 5-7 represent a detour from the original story arc. So there may be more than 9 books eventually if the author, his publishers, and his readers don't lose interest first.)A Tabletop RPG adaptation has been published, using the Basic Roleplaying game system - the very same system used by Call of Cthulhu and it's own lovecraftian spy setting, Delta Green.
Dominique "Mo" O'Brien who started off as a Damsel in Distress in The Atrocity Archives, but in The Jennifer Morgueturns out to have been Bond in the destiny trap and saves the day with her demon-killing violin. Bob lampshades this in Memorandum by noting that he'd rescued Mo in Archives, and since then she's been overcompensating.
Ramona Random in The Jennifer Morgue.
The Apocalypse Codex has Persephone Hazard.
Affably Evil: If you manage to get on Angleton's bad side, the friendlier he is to you, the more doomed you are. If you catch him chuckling, you are already dead, or worse.
Subverted in The Atrocity Archives; it turns out that it's not an alien world, but an alternate Earth and the reason the sky looks different is that the Infovore has consumed all the heat from the stars.
In The Fuller Memorandum, the world on which the dead plateau is found has a galactic core or supercluster visible in the sky.
A Load of Bull: The RPG brings its own take on the minotaur in the form of ASTERION SNARL. Like the medusa in "The Concrete Jungle," it's not an actual intermingling of man and bull so much as possession by a low-grade demon that results in increased bulk, monstrous rage, bone-like growths from the head, and a penchant to wander around labyrinthine structures. It's possible for the minotaurs to reproduce, however, resulting in a child that doesn't lack in size and easily makes up for its parent in mental stability.
All Take and No Give: Mhari and Bob's relationship. She sleeps around on him, hoping to trade up to a better boyfriend, and then comes sauntering back for a safe bet when that doesn't work out, and blows up at him when he gets mad about it. Of course, we only really get Bob's bitter word about it.
Animate Dead: The Laundry uses zombie security guards. Of former employees.
The Jotun Infovore is a high Class X-5, failing to enter Class Z primarily due to the difficulties inherent in consuming itself.
CASE NIGHTMARE GREEN could be anywhere between a high Class 1 and a Class X-4, depending on how nasty what comes through turns out to be.
Arbitrary Skepticism: Lots of this in Equoid. Bob is not pleased when sent to investigate a report of unicorns, especially when it requires him to read background material by that old fraud H.P. Lovecraft. Turns out unicorns are a form of Eldritch Abomination and Lovecraft was not entirely full of it. But Bob assures us that "Old Bat-Wings" does not exist.
The first line of The Rhesus Chart is:
"Don't be silly, Bob," said Mo: "Everybody knows vampires don't exist."
Arc Words: The Rhesus Chart has "Everyone knows vampires don't exist."
Artifact of Doom: Mo's violin is clearly an evil device that, in any other story, would be the subject of a quest to destroy it. In this universe, however, it's a useful tool for the good guys. But it does seem to be able to override the will of its wielder.
They'd like to make more like it, but then, "just owning the necessary supplies probably puts you in breach of the Human Tissues Act of 2004, not to mention a raft of other legislation."
In fact, Mo tries to go out of her way to prove to her superiors that CASE NIGHTMARE GREEN won't require the production of more violins.
Asshole Victim: Harriet and Bridget, at the very least. If you wind up on Angleton's desk, chances are you deserved it.
The villain in The Jennifer Morgue attempts this. His plan depends on the Laundry and the Black Chamber trying to stop him - see Invoked Trope below. Needless to say, it doesn't work out.
The Jotun Infovore in The Atrocity Archives is just as nasty and manipulative. It targeted Mo to get the Laundry on its tail, then abducted her into its reality, while dropping hints that the Nazis were behind the whole thing. This forces the Laundry to pursue it in force with a nuclear weapon just to be on the safe side. That's exactly what it wants: a burst of powerful, concentrated energy like a hydrogen bomb is what it needs to open a big enough gate to our reality so it can feed on all that delicious energy in our universe.
The Rhesus Chart as a whole. An ancient vampire who embedded himself in the Laundry used the Laundry itself as a tool to take down an even older vampire, by tempting the elder to create a "nest of baby vamps", then arranged for them to be snatched up by the Laundry and thereby blow away plausible deniability, then co-opting the elder vampire's pet vampire hunter, then manipulating the elder vampire to attack the Laundry personally. If the plan came of smoothly, the elder would be eliminated with prejudice by the Laundry, and even if it failed, both would be less one frustratingly effective government agency.
Battleaxe Nurse: "Down On The Farm" has robot nurses, slaved to a 1960s minicomputer with a demonic intelligence system
Because Destiny Says So: In The Jennifer Morgue, Bob and Ramona are destiny-entangled and it turns out that the villain trapped him in a James Bond destiny trap.
Beethoven Was an Alien Spy: Alan Turing was also murdered by the Laundry. Their regret over having wasted such a peerless mind heavily informs their latter-day approach to dealing with people on the outside who have happened upon knowledge only permissible to people on the inside.
And he's not the only famous person with skin in the game. Arthur Ransome (yes, that Arthur Ransome) and Ian Fleming were both close correspondents of the first head of the Laundry, and did a fair bit of occult field research for him. Ungern-Sternberg and the Bogd Khan had a hand in containing the Sleeper in the Pyramid, a potentially world-ending entity, through means best not dwelt upon. And yes, Lovecraft knew the truth, or at least enough of it to be dangerous, and his fiction is considered the occult equivalent of The Anarchist's Cookbook (more likely to produce results harmful for the reader).
Beneath the Earth: Humanity shares the planet with at least two other sentient species. The Deep Ones, code-named Blue Hades, live just beneath the seafloor and could curb stomp humanity if ever they're pissed off. Luckily for humanity they seem to be fairly reasonable folks, and the occult agencies liaise with them a semiregular basis. The Deep Seven, creatures known in the Cthulhu Mythos as Chthonians, live deep beneath the upper crust in the polar regions. Very little is known about them, save that they are polymorphous, and that the Deep Ones are terrified of them. Humanity's saving grace, as always, is that it's not really important: Neither species feels threatened by us, and they don't want anything that we have, so there's no reason to leave their environments.
Bond Villain Stupidity: Billington was already a Blofeldian figure (Corrupt Corporate Executive, planning a scheme to Take Over the World, using a yacht converted from a warship), so casting a "destiny trap" to create a James Bond-like figure is risky at the very least. It's justified, partly because Billington thought he could turn it off at any time and partly because he was insane and possessed. It's later pointed out that if Billington had simply approached the Black Chamber with his salvage scheme he would have gotten away with it.
Brave Scot: Johnny McTavish from Codex, who grew up in an isolated Scottish fishing village with rather disturbing theological practices before running away and vowing never to return to that church.
Brick Joke: Bob keeps making references to "paperclip audits" through the series. It seems like a Running Gag, until we actually get to see the start of one. Shortly therafter, we learn that if you have a paperclip from the same batch as a classified document, you can use it to track said document.
Building of Adventure: the Laundry HQ often becomes this, due to the sheer amount of magical artifacts, powerful wizards and classified information present there and the cutthroat bureaucratic politics that surrounds them.
The Laundry has control of TEAPOT, also known as the Eater of Souls. Well, they think they have control of it. Turns out that it's here voluntarily.
The Sleeper in the Pyramid on the Dead Plateau is a more straightforward example; it's an unspecified Eldritch Abomination that's being held inside a pyramid on a distant planet by observer effect magic. The structure is surrounded by a Wall Of Pain of impaled victims that are just barelyalive enough to constantly observe it and collapse its wave function into a "captive in the pyramid and dormant" state. The RAF has a special wormhole airplane that does a flyby over the Plateau every once in a while, just in case. Further details are revealed in Codex: first, the Wall of Pain is set to come to undeath and chase down any interlopers who try to awaken the Sleeper. Second, waking the Sleeper isn't the hard part. It's feeding him enough souls to open the Outer Gates that's the difficult bit.
The Black Chamber likes doing this with its operatives. Two of the characters in Jennifer Morgue have had soul eating abominations bound to them and are then in turn wrapped up in a few layers of powerful control magics to keep them on a short leash.
And signing on with them at all means "wearing the Dark Mark". And their Dark Mark is something Voldemort only wished he'd been able to create.
Cast from Lifespan: Some of Persephone's more exotic abilities have this drawback. Bob implies Mo's violin might also do the same, though whether it's a short-term drain she can recover from or siphoning off her long-term lifespan is unsaid.
The various occult intelligence agencies can't seem to help it. Even when they're allied and want the same thing, they always end up double-crossing each other, trying to spin the situation to their advantage.
The career bureaucrats in the Laundry (particularly in Administration and HR) also seem to suffer from this, in addition to being obstructive bureaucrats. To the point where you can be certain that if Bob's current manager is a character in the story, he/she will be involved with the Big Bad in some way.
Clap Your Hands If You Believe: Usually, demon-summoning requires a fair bit of effort. However, when the stars are right, just believing in something will be enough to call it forth from the vasty deeps. Worse yet, in about a decade there is supposed to be a period when just about anythingcan walk right into our universe as long as people believe in it. Like, say, high-school witchcraft clubs. Worse worse yet, the latest novel suggests that this period has already begun.
Overtime shows exactly how this sort of thing can and will happen. Belief in Santa Claus allows a monster that Bob snarkily names "The Bringer of Gifts" to enter the world at the focus of greatest belief in foreign-reality entities: The Laundry. Bob has to "complete the ritual" by mimicking the usual Santa Claus traditions; snack and milk in exchange for a gift and then leaving. If he failed to get the critter its snacks in time, the entity would be no longer bound to obey the ritual and can do as it pleases, which involves neither leaving the premises nor leaving Bob uneaten.
While not exactly a car, the Kettenkrad is cool enough to be salvaged from a bleak, airless alternate dimension where Axis has won WWII (And promptly caused an apocalypse), and lovingly restored by Pinky and Brains to working condition.
Subverted in The Jennifer Morgue, where Bob is stuck with a Smart car. He's not very happy about this, mainly because he has to drive down the Autobahn to a conference and keeps getting blitzed by Audis. On the other hand, once Pinky and Brains jam the obligatory load of James Bond-esque gadgets in it...
And then re-subverted when, at the end of the day, it's still a Smart Car stuffed with Bond-esque gadgets...
Cool Boat: Billington, the Blofeldian supervillain of The Jennifer Morgue, owns not one but three. Mabuse, a denavalized ex-Indian Navy Krivak III-class frigate, is his yacht. The ex-Glomar Explorer is the 66,000-ton salvage ship he's bought to enact his plan. And the Hopper only ever puts in an offscreen appearance, but it's mentioned as a old liner that's wired up with enough satellite bandwidth to serve as the nerve center of his business/surveillance operation.
Cowardly Lion: Bob is quite up front about hating being put into dangerous situations and yet every time he is performs beyond expectations.
Critical Failure: During The Fuller Memorandom when Iris tries to summon the story's monster of the week into Bob while he casts a summon of his own — from inside his freaking head, even! — Bob leaves his body and is PULLED RIGHT BACK IN thanks to her summon. Nice Job Fixing It, Villain.
Darker and Edgier: The Fuller Memorandum is considerably darker in tone than previous stories in the series. Not to be taken as representing a trend—The Apocalypse Codex is rather less bleak.
Equoid is outright disturbing and very dark, worse than Mo's description of CLUB ZERO in Fuller Memorandum or what Persephone stumbles over during her escape in The Apocalypse Codex; the Laundry series hints at many horrors, but almost never describes them outright or in detail, and Equoid serves as an example of why we should all be grateful for that; many commenters on the story called for Brain Bleach. Word of God, also mentioned in the comment section, is that it was for a unicorn story anthology John Scalzi was trying to get going, and for which Stross volunteered.
Deadly Upgrade: The series' magic is a branch of mathematics, and can be executed essentially by solving math problems. This is easy and (relatively) safe if done by computer, but mathematically sophisticated sorcerers can do it mentally — at the risk of ending up with Krantzberg syndrome: summoning microscopic and hungryEldritch Abominations into their own skulls, leading inevitably to a particularly nasty species of dementia. There is a risk of doing so accidentally.
Deconstruction: Of various Spy Thriller tropes. Intelligence officers are desk jockeys on civil service salary, the Laundry aims to be the first fully ISO 9000 certified intelligence agency (with all the paperwork that implies), and even active field agents spend most of their time in briefings and committee meetings. Not to mention the permanent squabbling over the budget. All of which are more or less Truth in Television.
Demonic Possession: A common plot element. In particular, a botched summoning at the climax of The Fuller Memorandum causes Bob to get possessed by himself.
Depleted Phlebotinum Shells: Standard ammunition for the Laundry takes the form of "banishment rounds"—silver-plated bullets with spells engraved onto them in 90-nanometer scale. Takes care of certain nasties being Immune to Bullets very nicely, and it still works on other targets as well.
Diesel Punk: The memex, a WWII-technology hypertext database that uses kilometers of microfilm, millions of wristwatch-precision cams and gears and a very nasty effective magical defense system. Angleton isn't stupid, and there's a perfectly good reason why he uses a machine so outdated that it shouldn't exist: there's this procedure called Van Eck phreaking that you can use to eavesdrop in a CRT or LCD monitor and gain access to classified information. The memex uses microfiche readers, and is not vulnerable to this method. It also cleanly averts Everything Is Online and the myriad of Laundry network problems that Bob always complains about.
Bob observes that Angleton's office is already TEMPEST shielded, so van Eck attacks would be impractical if the attacker wasn't in the same room as the terrifying sorceror. The implication is that the memex is there to protect some something else.
Disaster Dominoes: Bob notes early in Memorandum that no disaster is a single event; instead, they're the result of a whole chain of small missteps that all add up in a spectacularly wrong fashion. This comes back as a Brick Jokewhen Iris and the rest of the Brotherhood of the Black Pharoah try to sacrifice him to summon up the Eater of Souls. Unfortunately for them, they've made a chain of missteps and misunderstandings: nothing disastrous individually, but in toto...
Which is itself a bit of Fridge Brilliance. The basis of Chaos Theory is that miniscule changes in initial conditions can result in wildly different results when run through the same set of mathematical processes. Replace "conditions" with "mistakes" and "mathematical processes" with "plans."
Eagleland: Um...is there a type three? Because while the Laundry and their European counterparts aren't exactlythat good, they're about as nice as an organization can be in a world where Lovecraft Was Right. The Laundry's American counterpart, the Black Chamber, on the other hand, is basically outright evil, as are most other Americans who turn up as characters in the series. Basically the Supreme Court in the land of the free has taken What Measure Is a Non-Human? to its most extreme conclusion, by declaring that the Constitution only applies to humans, and only pure humans at that. The Black Chamber, officially the Operational Phenomenology Agency and once memorably described by Bob as "not so much our sister agency as our psycho ex-girlfriend turned bunny boiler", loves taking the "human" out of "human intelligence", using lots of golems, zombies, Deep Ones, and the like, all of whom are said to have had no choice in becoming disposable tools for the organization. And the handlers of the various creatures are just brutal. Their handlers ARE human, but are apparently enchanted and geassed up to the eyeballs so hard that they don't have even the minor freedom that the nonhuman grunts have. The only difference is that the nonhuman grunts are conscripts, and the handlers are (implied to be) volunteers. As demonstrated in The Apocalypse Codex, even death doesn't end employment with the Black Chamber. And not in a Residual Human Resources sense either. Indeed, they're proud of this; their motto is "Death is no escape." Admittedly, the same scene demonstrates what happens to those who break their oath to The Laundry, and it's not pretty.
The name, "the Black Chamber", originated as a sobriquet for the Cipher Bureau, which was the United States' first dedicated cryptanalysis bureau, and thus a spiritual, if not lineal, predecessor of the National Security Agency.
Eldritch Abomination: As you can expect in a Cosmic Horror Story, there's a whole hierarchy of them, coming from the many branches of the Multiverse: there's your average preta zombie-maker, which is closer to a few lines of necrosymbolic code than an actual lifeform. There are also the Feeders in the Night, which possess multiple bodies at a time and can spread by touch. Near the top of the ladder there are things like TEAPOT, which is as intelligent as, if not more so, than a human being, and very proficient in the occult disciplines. On the reality-altering level you have the Jotun Infovore and the Sleeper In The Pyramid On The Dead Plateau; having one of them summoned/awakened/released from captivity means you can pretty much kiss your universe goodbye. Above them still, you have The Black Pharaoh himself, Nyar lath'Hotep. Yes, that one.
Empowered Badass Normal: Bob starts as an ordinary, albeit very competent, human, but gains the ability to among other things eat souls thanks to the events of The Fuller Memorandum. Persephone Hazard coaches him a little on it during The Apocalypse Codex.
The Rhesus Chart has Bob upgraded into the Eater of Souls when Angleton dies, inheriting most of the powers (including the scary authority inherit in the position)) and all the knowledge contained inside Angleton's Memex.
The End of the World as We Know It: CASE NIGHTMARE GREEN. In essence, billions upon billions of humans doing what we do—thinking, imagining, calculating—is very bad for reality. Sufficient levels of belief in an entity, or calculations related to an entity, can summon it from one of the countless parallel (and... not so parallel...) universes where an iteration of it exists. In the best of times, the ability to do so is generally offset by the difficulty. However, a roughly 70-year period is coming very soon—and probably has already begun—during which... well, during which the stars are right. CASE NIGHTMARE GREEN is predicted to be bad enough that an all-out nuclear war was considered, in order to reduce the population and thus the chances of summoning something big and hungry. However, the sheer number of deaths would almost certainly attract equally unpleasant creatures—and that's assuming that nobody dedicates the deaths to their favorite gibbering horror.
Enemy Mine: The Black Chamber is, as discussed above, downright evil. They're still responsible for keeping Eldritch Abominations from getting into the world (probably), though, so they have cooperated with The Laundry now and then.
Energy Beings: Many summoned beings don't have their own bodies, and so must take possession of an existing one to exist in our universe. If it's a living body, it's often a case of Demonic Possession; otherwise, some beings—like the Feeders in the Night—will take hold of corpses. Since they're electrical creatures piggybacking the physical nervous system of a real body, though, it does mean they're vulnerable to electrical energy, like tasers.
Evil Is Deathly Cold: The "Jotun" Infovore and many lesser abominations suck heat out of the environment. Spells can have the similar effect. In fact, unnatural cold often serves as the most obvious warning that something is horribly wrong.
Specifically, following the mathematical rules of The Verse, especially powerful Eldritch Abominations will absorb information from existing systems. In macroscopic terms, this tends to cause things to get deathly cold, as a complete absorption of information would maximize entropy and cause all matter and energy to eventually reach a universal equilibrium where all matter and energy stops doing anything. This is why the Jotun Infovore was hoping to receive a nuclear explosion and therefore get a huge blast of fresh entropy to feed on, after having almost completely drained its entire universe.
Expy: Persephone Hazard and Johnny McTavish in The Apocalypse Codex are thinly disguised versions of Modesty Blaise and her sidekick Willie Garvin. Persephone's codename is even Bashful Incendiary...
Fate Worse than Death: Extremely common throughout the series, including some quite creative ones. The consequence is that various characters quite willingly and casually risk their lives, since a violent death is seen as an unpleasant fate, but absolutely not as the worse thing that can happen.
One of the reasons that Bob and Mo don't have children is because they know that if CASE NIGHTMARE GREEN comes to pass, slitting their own children's throats might be the best option to save them from an even worse fate.
The Fettered: Angleton. Looking at the RPG, it's mentioned that whereas other PCs roll Sanity checks when confronted with danger, he rolls Etiquette. And when it reaches zero... it isn't good for anyone.
Fish People: Blue Hades are an extremely advanced species, living on and below the deep sea floor, that have been around for millions of years. The various occult spy agencies stay in semiregular contact with them via Half-Human Hybrid go-betweens. To their credit, they aren't hostile towards humanity (mainly because they've little use for the regions that mankind populates) which is just as well considering that they could wipe out much of us surface-dwellers via volcanoes and tsunamis. Angleton speculates that they have even more advanced weapons that humans cannot comprehend, comparing it to a soldier pointing a bayonet-tipped assault rifle towards a headhunter (who would only see a Blade on a Stick.)
Foreshadowing: Early in Codex, Bob is sent off to a training course whose purpose is to identify talented administrators and managers from other government agencies, in case the Laundry needs to suddenly conscript them to fight CASE NIGHTMARE GREEN. By the end of the book, Bob himself has passed his "test" with flying colors, and is conscripted into the secret-beyond-secret core of sorcerers and administrators who actually run the Laundry: Mahogany Row.
For the Evulz: Not all of the eldritch abominations in the series, are driven by simple Horror Hunger. And this will be really unfortunate for humanity if one of them breaks into out universe. Cultists of the Black Pharaoh have shades of this as well.
From Bad to Worse: The Fuller Memorandum has this in spades. It starts with an utterly bleak prologue, then lightens a bit in the first chapter, but things go rapidly downhill from there. (That said, the ending turns out to be not quite as bleak as the prologue implied.)
The Rhesus Chart starts with a bad quarrel between Bob and Mo, and ends with the death of Angleton and several important side characters, and Bob separating from Mo.
Fun with Acronyms: The Free Church of the Universal Kingdom (FCUK) is only a slightly scrambled version of what they plan to do to humanity...
From "Equoid": Enhanced-Mobility Operational Capability Upgrade Mounts (EMOCUM)
Inverted with the information campaign for CASE NIGHTMARE GREEN. It is classified as KGB.2.YA, which doesn't sound too bad until you realize it's short for "Kiss Good-Bye 2 Your Ass".
Tropes G - P
Gambit Pileup: The Jennifer Morgue — Billington, the Black Chamber and the Laundry are all counting on each others plotting to achieve their own goals.
Small ones to ensure secrecy are thrown around all the time.
In the second book the protagonist is put under a geas that essentially turns him into James Bond. Too bad it's a trick by the big bad.
TEAPOT, also known as Angleton, is controlled by one. It wore off decades ago.
Genre Blindness: In The Jennifer Morgue. For a pop-culture quoting geek who claims to have seen all the films and books in question before he was 15, Bob takes an awfully long time to realize that the archetype he's labouring under is James Bond. He even gets a cabin where the DVDs are all Bond titles, and still doesn't figure it out. To his credit, he easily figures he's in some kind of thriller, but even after Ellington tells him that the archetype in question has been reinforced by millions of viewers over fifty years of film — while they're at dinner— he still doesn't catch on. (Partially this is because the archetype itself is keeping him from realising, since he's more the (good) Bond girl rather than Bond himself; also, Ramona Random mentions that it's designed to prevent "recursive attacks", i.e. trying to brute-force your way through the geas by taking advantage of the knowledge of James Bond.)
Genre Savvy: The villain of The Jennifer Morgue magically enforces a genre on the situation and the hero. All involved factions are aware of this and try to exploit it to their own advantage - it gets complicated near the end, when everyone tries to play their endgame at once, all of them slightly different than the other parties expect.
Geometric Magic: various bits of magic in the series involve "Dho-Nha" curves, easily derived by proving Turing's last theorem. These curves amplify through space-time, tearing through reality and causing magic to happen. Bob's experimenting with unusual fractals comes dangerously close to generating a Dho-Nha function, and summoning an Eldritch Abomination to destroy Wolverhampton.
"The Concrete Jungle" shows that SCORPION STARE is supposed to be fed over every CCTV camera in Britain for use as a remote controlled defence grid, regardless of the potential body count when CASE NIGHTMARE GREEN comes about.
Angleton mentions in The Jennifer Morgue that one of the support vessels for the operation, open for a "direct line of credit", is HMS Vanguard. Considering that the Blofeldian supervillain wants to resurrect an ancient Cthonian war god, having a sub full of ICBMs on standby suddenly looks like a reasonable precaution.
Going Native: The Fuller Memorandum reveals that this is Angleton's backstory. Bob suspects that he might be just siding with humanity because it gives him the best chances of survival during CASE NIGHTMARE GREEN, though.
Gone Horribly Right: A mild version of it. Angleton, a.k.a. TEAPOT, was originally trained to be a weapon, an Eater of Souls under the command of the Laundry's predecessor. Unfortunately for J.F.C. Fuller and the rest, when it was trained/indoctrinated to pass for human, it absorbed the British ideals—fair play and honour and a very sharp sense of humor—more than its cynical human masters did, rendering it useless in its original purpose of a hungry ghost. Instead the SOE assigned it to management, where it performs stellar service as Angleton.
Good Shepherd: Pete, a local vicar and a friend of the Howards, shows up in Codex. Even though Bob claims to be an atheist (actually, closer to a Nay-Theist, but he couldn't well reveal the truth about betentacled Elder Gods and the like), he respects him for genuinely taking care of his flock's spiritual needs. Doubles as a Chekhov's Gunman when Bob needs a theological scholar to analyze the Apocalypse Codex of Saint Enoch, which Pete quickly deciphers as a guide to a ritual, not to mention deeply disturbing: Bob has to reassure him that, no, he hasn't gone batshit crazy and joined that particular church. Bob, naturally, feels really guilty about dragging him into it.
Happily Married: Following the events of "Jennifer Morgue", Bob and Mo have a very healthy relationship, despite the looming specter of CASE NIGHTMARE GREEN.
Hellish Horse: The eponymous "equoids" in Equoid are large, bad-tempered, have sharp teeth, and eat meat (raw, and, for preference, alive). They're equipped with saddles that are pretty much cages, as much to protect the riders from their mounts as much as from whatever they might be riding toward.
Heterosexual Life-Partners: Persephone and Johnny in Codex, despite both of them being attractive people and Johnny at least liking women. Despite their clear close friendship, there's basically no romantic interest between them at all.
History Marches On: Minor case for Archive. A throwaway exchange has Mo find a copy of the missing volume four of Donald Knuth's The Art of Computer Programming (sort of like The Bible for computer scientists) on Bob's bookshelf. Bob explains that the Laundry has a deal with Knuth: "he doesn't publish volume four, and we don't render him metabolically challenged." In real life, the first part of volume four was finally published in 2005, one year after Archive.
Then again, what Bob has is the un-redacted version.
For the Islamic fundamentalist terrorist group in The Atrocity Archives, Charles Stross was originally going to have them be Al-Queda: "an obscure but fanatical and unpleasant gang who might, conceivably, be planning an atrocity on American soil".
Hoist by His Own Petard: at the end of The Apocalypse Codex, Pastor Schiller is left in the Pyramid with the newly-awakened Sleeper, whom he awakened, and who is hungry for souls to eat.
Horror Hunger: Why most of the Eldritch Abominations appearing in the series are interested in humanity. Lots of them feed by increasing entropy (including destruction of information), so killing intelligent beings and (for more powerful ones) sucking out their souls gives them excellent nutrition.
Humans Are Special: Unfortunately, only in terms of danger the humanity unwittingly poses to itself, the Earth and the Universe. Other races don't seem to have quite the same potential for summoning malevolent soul-sucking Physical Gods by accident or stupidity, as evidenced by the world not being reduced to a toy of said gods yet.
Insane Troll Logic: The Laundry's response to a committee in The Seventies which suggested using the Mother of a Thousand Young as a Weapon of Mass Destruction — even to develop such a system would invite a preemptive strike from the Soviets or the destruction of mankind by Blue Hades. The Laundry recommended that all the members of this committee be forced into early retirement and "denied access to sharp objects".
I Should Write a Book About This: At the start of The Apocalypse Codex, Bob mentions that he has been encouraged to document his experiences in the field to serve as a (highly classified) resource to assist in training new Laundry agents.
I Want My Jet Pack: It's explained in the books that some "future" concepts are possible but are suppressed due to supernatural consequences (certain forms of computing open portals to hell-dimensions, underwater human bases would really piss off BLUE HADES, etc)
If You're So Evil, Eat This Kitten: If you're really a Humanoid Abomination, eat this baby. Bob manages to pass as an Eater of Souls. Rather, he's forced to drink the baby's blood as part of a binding ritual for the Eater, and his resistance is accepted by the cultists as the Eater not wanting to be bound. He does find the taste of blood worryingly delightful during this time, though.
Incompetence, Inc.: The Laundry finds it easiest to deal with people who can't be let go by simply giving them a pointless paper-pushing job until they can retire with a pension. It's cheaper in some ways, and it avoids a lot of nasty legal and PR issues.
The root of the matter is that they hire as an alternative to killing random civilians, and this is almost the only way anybody comes to work for them. Unlike a standard setup where people are Kicked Upstairs, all of the lowest-level jobs are sinecures.
Instrument of Murder: The Jennifer Morgue plays on this; Bob's girlfriend, Mo, carries a Zahn-model violin that she wields like a weapon. In an amusing Shout-Out to Woody Guthrie, the violin has "THIS MACHINE KILLS DEMONS" written on it. The violin itself is a shout out to the Lovecraft short, "The Music of Erich Zahn".
In the Blood: Johnny McTavish carries the bloodline of Lilith, which carries supernatural properties and is needed in a ritual. McTavish is an escaped member of one of the half-Deep One churches, knows exactly what the purpose entails, and has no intention of letting it come to pass.
Whether Lilith existed or not is hard to say, but his ancestors presumably engaged in a little bit of hanky-panky with the Deep Ones so he isn't quite like a normal human.
Killed Off for Real : By the end of The Rhesus Chart, OCCULUS trooper Steve Howe, Andy Newstrom, and Angleton, who have been around since the first book, are all killed.
Killed to Uphold the Masquerade: Deconstructed; the predecessors to the Laundry did this to Alan Turing. Since he was, you know, Alan Turing, this merely meant that they lost a potentially really useful resource when they could have achieved the same basic effect and made use of his skills and intelligence by simply drafting him into the service and making him sign the Official Secrets Act. After kicking themselves thoroughly, the Laundry went on to make averting this a matter of policy.
Lighter and Softer: Compared to Stross's two earlier Cold War short cosmic horror stories "A Colder War" and "Missile Gap", in which humanity is brought to extinction by an all-out war and in one case, the remnants escape only to die of cold and starvation in an alternate dimension, the Laundryverse is downright optimistic about humanity's chances.
Locking MacGyver in the Store Cupboard: In The Jennifer Morgue, the Hero Trap induces Bond Villain Stupidity on the villains holding Bob captive. They lock him in a stateroom in the yacht of the Big Bad, and while they do remove the obvious computer from its desk, they forget to check the television - which is an unsecured, network-capable Windows Media PC. And when Robert Oliver Francis Howard is not in the field, he's essentially the official Bastard Operator from Hell for Her Majesty's occult secret service...
Lovecraft Lite: For the most part, as long as CASE NIGHTMARE GREEN isn't involved.
May Contain Evil: Downplayed and played for laughs, then subverted. Apparently Apple puts mild glamours on its products to make people want to buy them. Early in The Fuller Memorandum, Bob ends up falling for the glamour and buying an iPhone. It ends up saving his life after Pinky installs anti-monster apps on it without permission.
The Men in Black: Most major powers in the setting maintain their own occult intelligence services. So far, we've seen the Laundry for the British, the Black Chamber for America, the Faust Force for Germany, and the Thirteenth Directorate for Russia.
The Mole: Iris Carpenter in The Fuller Memorandum.
More Dakka: Laundry agents are discouraged from carrying guns around; they tend to be much more trouble than they're worth. On the other hand, when they do get authorization they get all kinds of fun toys. Like the Atchisson AA-12 that Harry the Horse offers Bob, who thinks it'd be great for clearing unwelcome visitors off their front step—and the sidewalk, and the street, and the neighbors across the street, and anyone in the neighbors' backyard as well...
Whatever Bob did the one time he succumbed to the urge to respond to a 419 Scam. All he'll say is that Laundry Internal Security waxed sarcastic at him for half an hour, and them made him give the scammers back their bank.
No Such Agency: The Laundry and equivalents in other countries (Black Chamber, Thirteenth Directorate, and so on).
No Such Thing as Space Jesus: there are various cults that identify Jesus with any one of a number of horrors, not realizing that calling him back would certainly not result in rapture (although the apocalypse is almost certain should they succeed). Most of the Laundry is skeptical about him; Johnny McTavish sums up the main issue with associating him with a soul-eating horror:
...he grew up with this deviant theology, although he doesn't hold with with it himself—the doctrine that Jesus was a supernatural vessel for the Gatekeeper is inner doctrine, but he considers the idea that the Sermon on the Mount was delivered by a sockpuppet for the Sleeper in the Pyramid to be somewhere between implausible and hilarious.
Oh Crap: Or as it's known in the trade, an Unscheduled Reality Excursion.
Or Are You Just Happy to See Me?: a variant on the phrase is used as a joking bit of spy speak (no, really!) in Concrete Jungle, when Bob needs to identify himself to the OCCULUS team he just called in. To be fair, "is that a gun in your hand or are you just here to have a wank?" is not a phrase most people would utter when staring down the snout of a carbine.
Our Mermaids Are Different: The half-Deep Ones are aquatic lifeforms but not half-fish, avoiding the Mermaid Problem. It's explicitly mentioned that some Laundry employees "start spending too much time skinny-dipping with a snorkel". They actually look passably human as long as they don't spend too much time in salt water. Otherwise they eventually change into Deep Ones, Innsmouth-style. Ramona Random says that those like herself are intended to look good and associate with humans more, while the "bumpkin cousins" sporting the ugly half-transformed "Innsmouth look" are decidedly more common.
Our Souls Are Different: They're the informational echoes of a person's consciousness; although these echoes can occasionally haunt a spot as a ghost, souls are of more significance as food for various otherworldly abominations.
Our Zombies Are Different: They're demons bound into reanimated corpses. The garden-variety are not very clever, and are apparently programmable if you know the right language. However, there are many types of demons, and accidentally summoning the wrong kind gives rise to a possessed corpse that can steal souls by touch. Oh, and make all the Boom, Headshots you want. It won't help.
Painting the Medium: Codex switches between first and third person narration, all written by Bob. His idiosyncratic narration bleeds over into the third-person sections, such as when the decidedly non-geeky Johnny makes an "all your base" reference during a phone conversation.
Though admittedly, it is mentioned that Johnny plays World of Warcraft, so he might be more geeky than people give him credit for.
Also in that book, a P90 is described variously as a machine pistol, a submachine gun, a "big gun", and a machine gun, all within a few pages. None of those are technically correct; it's a "Personal Defense Weapon", though SMG comes closest. Bob mentioned earlier - and shows during the sequence in question - that he's crap with guns. Hence his problem identifying it.
Powered by a Forsaken Child: Pale Grace Skin Hydromax cream. Made from "100% natural ingredients". There are also various other rituals and artifacts requiring human sacrifices.
Precision F-Strike: Bob is generally gleefully profane in his narration; on the other hand, when Angleton curses, you know things have really gone to shit. Whereas, when Angleton says "Oh dear", you know the situation has... gone significantly outside anticipated operational parameters.
Precursors: ANNING BLUE SKULL, the Elder Things, created life on Earth before being wiped out by their creations, ANNING BLACK (the Shoggoths). Everyone from the Nazis to the Black Chamber and Laundry is always eager to locate and study their technology (which is both deceptively simple and impossibly dangerous), because all evidence points to their having both encountered and survived a CASE NIGHTMARE GREEN-like scenario in their deep past. Since there's none of them left on Earth to ask, recent efforts have concentrated on the capture, containment and control/interrogation of Shoggoths.
Pride Parade: Bob explains to Mo in The Atrocity Archive that back in the day when it was against secret service policy to be homosexual because they viewed you as a security risknote true facts, homosexuals actually ended up as one because they were vulnerable to blackmail ("do this for me or I tell your boss and you're fired"). The solution ended up being to ensure that if an employee was gay, he was openly gay, since you can't be blackmailed if you're not hiding anything. Hence, once a year Camp Gay Pinky drags Straight Gay Brains out to Gay Pride to maintain the latter's security clearance.
Punch Packing Pistol: 'Basilisk guns', the Weapon of Choice for the Laundry's nerdier operatives, are really digital cameras loaded with a very special software package that explosively petrifies anything in the viewfinder, but function in all regards like a particularly powerful and well-disguised version of this trope. If a Laundryman wants to take your photo, run.
Punk in the Trunk: Bob gets stuffed in the trunk of a car by cultists in The Fuller Memorandum. With a badly injured arm, so he's in tremendous pain the whole ride.
Punny Name: Check the quote at the top of the page. Remember the "many-angled ones"? Think of what Angleton breaks down into.
Angleton. Not nice, but reasonable. He'll make fun of his subordinates if he feels they deserve it ("Go away, before I mock you," when Bob did something dumb in Archive) and does not suffer fools gladly (reference the fate of the late, unlamented Bridget), but if you're competent and make the effort he will back you all the way.
In The Fuller Memorandum, Iris. In contrast to his previous line managers Bob thinks she's the type who acquired her management skills shepherding a large, unruly family rather than in business school. Horrifyingly subverted when it turns out she's The Mole and head of a cult of Nyarlathotep.
Religion of Evil: Some of the bigger cults to various Things Which Should Not Be, including one masquerading as an evangelical megachurch in Apocalypse Codex, whose leader believes the Sleeper in the Pyramid to be Christ come again—and that it is his job to bring Him back via mass sacrifice.
Ret Gone: The 'Forecasting Operations Department'. The precogs who would be in the Department predicted that the formation of the Department would inevitably lead to disaster, resulting in them deciding never to form the Department in the first place.
Revealing Coverup: Averted. The Laundry only uses assassination as an absolute last resort for this very reason. They find it much more useful to recruit people who find out instead. This also doubles as punishment, since the job tends to force people to retire early.
Ritual Magic: It's almost exactly opposed to the Laundry's branch of ComputationalDemonology, in that it requires innate talent, a lot of it, to use properly without frying your own brain. It's also hinted to be just as powerful, if not more, than its more mathematical counterpart. Persephone Hazard turns out to be a practitioner.
Roleplaying Game Terms: Used for a gag in The Fuller Memorandum. Bob has just gotten his PDA fried and needs to pick up a new one. He just happens to stumble upon the iPhone sitting pretty in a display case. In Mo's words:
"Bob loses saving throw versus shiny at -5 penalty, takes 3d8 damage to the credit card."
Running Gag: Whenever Bob gets annoyed at the Laundry's bureaucratic excesses, he brings up the regular paperclip audits. Then they crop up again in the middle of The Fuller Memorandum and it turns out there's a very good reason for them: a Chekhov's Gun set up 5 stories ago. Whew.
Sarcastic Confession: The Blofeldian supervillain of The Jennifer Morgue jokingly claims that his plans for world domination are all for Fluffy's sake. "Fluffy" is the vessel for the mind of the ancient Eldritch Abomination that he plans on resurrecting.
At the end of The Jennifer Morgue, Bob breaks the Bond destiny by proposing to Mo.
"Overtime" also does this in its climax.
Secret Test of Character: Specifically invoked in The Apocalypse Codex when Bob is not told about his mission just to see how far his loyalty goes. It tends to surprise even his testers. (But not Angleton.)
Self-Fulfilling Prophecy: When Dr. Kringle prophesies that there will be no Christmas party next year, everyone assumes that it's because the Laundry will be overrun by gibbering squamous horrors by then. When Bob asks if they couldn't avert that by just canceling the party themselves, Andy derides the idea as ridiculous. (The rest of Dr. Kringle's news was that they'd done the math wrong and the apocalypse was coming early — and in fact had already started to warm up. Bob's suggestion was that they delay the apocalypse indefinitely by canceling the Christmas party so it can't be disrupted.) Dr. Kringle's morbid pronouncement kills the appetite at the office party, resulting in leftover pies which allowed Bob to banish Santa Claus. Otherwise, the horror would have taken up residence in the Laundry building and eaten everybody, thus making this a rare case of a Self-Averting Prophecy.
Bob also has a pair of middle names, Oliver & Francis, making his initials BOFH.
Known Discworld fan Stross equips Bob with a thaumometer in The Atrocity Archive. There's another joke there about being locked in the library by an orangutan if Mo stayed too late. Dungeon Dimensions also are mentioned.
Angleton is a Shout-Out to James Jesus Angleton, head of counter-intelligence for the CIA from 1954 to 1975 and generally remembered as a very strange man. (One particularly wild conspiracy theory had it that he personally ordered the murder of John F Kennedy because he thought Kennedy was a Soviet mole.)
By the way, this has the result of making it a seriously surreal experience to read the real-life Angleton's Wikipedia page shortly after reading the Laundry books. Try it.
"Equoid", in which Bob investigates a farm in Sussex, has numerous shout-outs to Cold Comfort Farm, culminating with Bob seeing something nasty in the woodshed.
To Dungeons & Dragons in The Fuller Memorandum. Mo's remarks on Bob's purchase of an iPhone:
"Bob loses saving throw versus shiny at -5 penalty, takes 3d8 damage to the credit card."
Angleton, at first; we learn more about him in Memorandum.
Persephone Hazard; the Laundry only has brief, tantalizing glimpses of her past lives—a war refugee from the Balkans, murdered adoptive parents followed by the sudden demise of some local cultists, suddenly-stellar university grades in various arcane subjects, et cetera.
Signed Up for the Dental: One of the Black Chamber's minions in The Apocalypse Codex explains to Johnny that he signed up with them because he had no other way to pay his wife's medical bills. It's Played for Drama; he's well aware of what the Black Chamber's work entails, and that joining them was a bad choice, but it was the only choice he had.
Someone Has to Die: At the end of The Atrocity Archive, someone has to stay behind to blow up the nuke manually and cause a "fizzle". At the end of the book, he's suffering the effects of radiation poisoning and the outlook is not the best, but then The Jennifer Morgue confirms he survived; he shows up again as the leader of The Cavalry after the cat dies. Lampshaded in the RPG, where Bob notes that there had to be some potent magic involved to keep him alive, and wonders just what the cost was...
Spacetime Eater: The Infovore, which feeds on quantum information and is thus actively causing the premature death of the alternate universe.
Space Is Cold: Stross did his research in The Atrocity Archives. Despite the ambient temperature on the alternate Earth being roughly 40 Kelvin, the characters note that since there's no air they can't lose heat by convection, so heat exhaustion is a potential danger.
Starfish Aliens: All of the aliens are patently bizarre, but GENOA FRACTAL, aka the Flying Polyps, are more akin to a sentient infection than a race: they develop as a "Stage-V metastasis" of cancer, where the tumor bursts out of the patient and starts floating around and killing people. Apparently a Mad Scientist has been making them via cloning; it's unclear how the ancient variety from Australia relates to them.
Stealth Pun: Bob is eventually revealed to have the middle names Oliver Francis, at the same time as he is reluctantly given an apprentice; Peter-Fred Young. So that's BOFH and PFY...
BLUE HADES, the Deep Ones, can sink most coastal nations and islands, and are apt at both genetic engineering and sorcery. Technically we've signed the Benthic Treaty which prohibits them from attacking signatory nations without a good reason, but the wording is more along the lines of "unless they feel like it" than anything else. They're at war with DEEP SEVEN.
DEEP SEVEN, also known as the Chthonians, can tectonically destabilize almost any land area on the planet, and a single one can lay waste to a whole city. It's unclear how much of it is technology and how much is their innate Fast Tunnelling.
ANNING BLUE SKULL, the Antarctic Crinoids or Elder Things, are pretty much everyone's Precursors, at least in terms of biology. The RPG book describes them as either genetically engineered or evolved to a staggering degree of perfection: in addition to their fabled resistance to everything from hard vacuum to crushing pressures, their manipulators have fingers that subdivide into bundles of five all the way down to the nanoscopic scale, allowing them to manipulate cells and DNA by hand. All of their surviving technology is impossibly advanced, with something as mundane as a heater making use of another universe for power. Moreover, their cities and ruins get into your head, dumping an understanding of their culture and society into the brain of everyone who spends a few hours exploring them.
PLUTO KOBOLD, otherwise known as the Fungi from Yuggoth or the Mi-Go have apparently been running mining colonies all over the planet, in near-complete secrecy, for millions of years. Apart from their hobby of snatching up the brains of people and random sheep, not much known about them. The Laundry has the head of one as a captive, but its responses are justMind Screwy enough that we don't know if it's real of a Black Chamber plant.
OLD DREAMER are The Great Race Of Yith. Again, not much has been said about them so far, except for one account in the RPG Rulebooks referring to a 19th century bloke who got snatched away by them.
Sunglasses at Night: The mooks in The Jennifer Morgue. Bob wonders why, and it turns out it's because they're wearing eyeliner, which their boss can use to monitor their eyes and ears. Since they have stock options, they don't mind, but the shades are because it's hard to take a guard wearing eyeliner seriously.
Supernatural Phone: Magic is advanced maths, and is therefore easier for computers to do than people. When Bob gets an iPhone, Brain gimmicks it to have the usual array of Laundry Agent spells as apps.
Taken for Granite: The basilisk effect, which converts carbon to silicon via spooky observer-effect magic. Then blows it apart thanks to the wildly unstable molecular configurations that result. Originally formed by a particular kind of brain tumour, SCORPION STARE is the result of the Laundry producing a chip that can duplicate the effect with a camera, allowing its use as a weapon. Any camera with the chip can be activated through an Internet connection, and this includes just about every CCTV, webcam, and digital camera in Great Britain. And you know those DRM chips Hollywood wants installed in all new cameras? Guess what those are.
They're actually just DRM chips: the in-universe point of the DCMA is that any chip capable of functioning as compliant DRM has both the computational power to emulate the appropriate cluster of nerve cells and the capacity to have its firmware updated to do just that, usually over the Internet. Neither the Laundry nor Black Chamber - as a whole - are stupid enough to consider actually globally deploying SCORPION STARE until the Godzilla Threshold is passed.
The Nazis were implied to have been working on forcibly creating human basilisks as terror weapons. The Allies considered this to be crossing the Moral Event Horizoninvoked and threatened use of chemical weapons on German cities if the project was not shut down.
Theory of Narrative Causality: Powers Billington's Hero-trap geas. He casts himself as the villain in a James Bond plot, limiting his opposition to one hero archetype, and at the critical moment plans to destroy the geas, leaving himself ascendant and unopposed. Of course, that would only work if he captured the true Bond figure, instead of the designated love interest — at which time, the plot becomes one of the variations.
He also failed to consider that Bond Villain Stupidity inflicted on him by the geas will also influence his attempts to shut down the geas. And that the last step of his plan while under the geas was 'turn off the geas at the right moment'...and the final step of Bond villain plans never succeed.
This Page Will Self-Destruct: happens to Bob's Powerpoint briefing in The Jennifer Morgue when he takes too long and doesn't get to finish it. Angleton is less than pleased, and resorts to sending him future briefings in his dreams.
Took a Level in Badass: Dominique, as a result of the Hero-trap geas. Bob himself steadily levels through the series, and is acknowledged as a good operative even in the first book. By book three, Mo herself has apparently kept the several levels of badass that she's taken, primarily due to her skills with the Erich Zahn-model violin, that the OCCULUS special forces team willingly accepts her presence on missions.
She even warrants her own codename now, CANDID. Single word codenames are exceptionally unusual, but whether this implies she is unusually important or not has not yet been revealed. Another such entity, TEAPOT, has a history dating back hundreds of years and the disappearance of its summoning ritual was enough to cause an international incident and be the cornerstone of a plan to usher in the end of the world ahead of schedule.
Bob himself. As a result of having his soul ripped out, then being summoned in place of the Eater of Souls at the end of book three., in book four, he has gained, among other, the ability to consume souls, and command certain types of undead.
Trauma Conga Line: The Fuller Memorandum, made clear from the onset (in the prologue). In order, Bob performs an exorcism that goes bad and ends up killing a civilian. The next day, Mo gets an even more traumatizing job and returns on the edge of a nervous breakdown. Then Bob gets attacked by a zombie, shot, attacked by Cthulhu cultists and narrowly escapes, his office is broken in, he gets an internal investigation set on him, gets suspended, attacked by the cultists again, kidnapped, gets part of his right arm carved up and eaten while he's fully conscious, and is very nearly possessed by the Eater of Souls. The latter ritual involving, among other things, the cultists killing a baby and making Bob drink its blood. Mind that the whole ordeal happens within a two-week period. At the end of it, Bob is a wreck both physically and psychically, as alluded to by both the prologue and epilogue. Though Overtime suggests that he does recover eventually.
Tuckerization: Dr Mike Ford, the Laundry researcher with the implausible eyebrows who appears in The Fuller Memorandum, is a tuckerization of author and fan personality John M Ford, to whom the novel is dedicated.
Ultimate Job Security: Everyone in the Laundry has it. They can get themselves killed through treason, failed coups or their own innocent stupidity, but no one is ever fired. This is because Laundry policy is to made dangerous people safe by employing them. To keep people quiet, in most cases they are given jobs in the Laundry (and Mind Control to make them incapable of discussing it with people without the proper clearance.)
Unexplained Recovery: The last time we see Capt. Alan Barnes in The Atrocity Archive, he's on a hospital bed being treated for 500 rems of radiation poisoning. Then in The Jennifer Morgue, he shows up with The Cavalry, looking like a recovered radiation-therapy patient but otherwise fine. Bob lampshades it in the RPG by wondering what the Laundry had to promise to whom to get this effect.
Unreliable Narrator: For one thing, his name isn't "Bob Howard", for I Know Your True Name reasons. Also, the characters sound slightly different when he's narrating in first person compared to the independent/"reconstruction"/speculation third-person bits. Details of Bob's past, like what exactly disaster he almost caused unwittingly before The Laundry found him also may vary.
Vast Bureaucracy: The Laundry. The Laundry has a policy of offering everyone who knows too much a job (killing them is too conspicuous and messy). As a result, they're completely overstaffed by incompetent (or at least untrained) drones with Ultimate Job Security. All the bureaucracy is just a way of keeping them busy.
The Virus: The Infovore of The Atrocity Archives, along with numerous other Lovecraftian beasties. Demons in the setting spread along electrical circuits, and skin is conductive...
What Would X Do?: In Codex, Persephone has a "WWLJD" bracelet. When she's trying to infiltrate Schiller's compound, everyone naturally assumes it stands for "What would Lord Jesus do?" Actually, it's "What would Leeroy Jenkins do?"
Xanatos Gambit: It's revealed late in Codex that Schiller's security chief is an operative for the Black Chamber. Persephone figures it out in time: if Schiller succeeds, the Black Chamber could potentially grab control of a powerful supernatural entity, and if he fails, they would be rid of a dangerous madman. Whether the operative was running a officially sanctioned or a rogue operation is left worryingly unanswered.
This is remakably similar to the setup in Jennifer Morgue, with the reasoning behind their actions left equally unanswered.
You Can't Make an Omelette...: Pinky and Brain try to prove this is in fact possible. Their results are somewhat dubious, but it proves to be a Chekhov's Gun when Bob uses their technique to disrupt the detonation of a nuclear device.
You Can Never Leave: You can leave the Laundry, just as long as you don't take a job in any area that might get you into trouble, like computing. Which rules out any job that Bob might be interested in.
Your Soul Is Mine: type 2/2B. Certain eldritch beasties, as well as machines designed for the role, can kill someone and then destroy their soul. Since many abominations feed by increasing entropy, the destruction of ordered data (like a soul) works well for summoning or feeding them.
