->"A police whistle on Bow Street. For a moment I felt a connection, [...] with the night, the streets, the whistle and the smell of blood and my own fear, with all the other uniforms of London down the ages..."

''Rivers of London'' is a series of books which follow the career of Peter Grant, Police Constable and apprentice wizard, as he tackles supernatural crime in London along with his superior officer, and Master Wizard, Detective Chief Inspector Nightingale. Written by former ''Series/DoctorWho'' writer Creator/BenAaronovitch, the series comprises five books so far. Aaronovitch has been commissioned to write a further three.

With its realistic London setting, it's a good example of UrbanFantasy where the {{Masquerade}} is maintained by a combination of stealth and public indifference.

There is a website where you can read about the background of the novel, including a CharacterBlog.


In June 2013 the series was optioned for television, and in January 2014 it was announced that Titan Comics had picked up the licence for a graphic novel adaptation (first installment to be called ''Body Work'' and due April 2015).

There is also an official [[http://libbylibby2.tumblr.com/post/68765662059/the-rivers-of-london-rap-written-composed-and Rivers of London Rap]] by Music/DocBrown and Music/MikisMichaelides.

!!The books contain examples of:


[[folder:Tropes A to K]]
* AboveTheInfluence: Peter turns down a very drunk Lesley about halfway through ''Whispers Under Ground''.
* AbsurdlySpaciousSewer: Which is connected to the Absurdly Spacious Subway System, which leads to an ElaborateUndergroundBase of magical folk. Forms the setting of ''Whispers Under Ground''; however in this instance (magic folk base aside) this is actually a case of [[TruthInTelevision Truth In Literature]]; the London Sewers and UsefulNotes/TheLondonUnderground ''are'' really that massive.
* AcronymAndAbbreviationOverload: The Metropolitan Police love this (probably TruthInTelevision). If an SIO in the SAU bungles his IIP, some ACPO will get his nose out of joint.
* AdultFear: There's bits throughout the series, but it hits a new level in ''Foxglove Summer''. First, two children go missing with next to no trace whatsoever, and Peter makes comparisons to Soham and the Ian Huntley case. [[spoiler:The kids are found... but it transpires that one of them is a changeling, and the original is still missing... until it turns out that no, that one is in fact the real deal, and the "original" was the changeling, who had been swapped more than a decade earlier without anybody noticing. The climax of the book is partly driven by the mother's desire to get the "original" back -- she'd raised her for over ten years, after all]].
* AintTooProudToBeg: Peter and, surprisingly, Lesley engage in some shameless begging when taken prisoner in book four as they wait for Nightingale to bring the cavalry.
* AlcoholicParent: Peter's dad is a serious and habitual heroin addict. He isn't a bad parent but just a bit ineffectual, although Peter's mother being an ApronMatron probably means she did all the parenting stuff anyway. As of the end of ''Moon Over Soho'' [[spoiler:he's clean, and remarks that of all the drugs he quit, nicotine was the hardest.]]
* AltumVidetur: The magic spells are all in Latin, but only because they were written down by Sir UsefulNotes/IsaacNewton (who used the language of Scientific Gentlemen of his day).
* AmericanKirbyIsHardcore: The cover of the US edition transforms Peter from a mixed race nerd (by his own admission he looks more North African than anything else) into a ScaryBlackMan.
* AndIMustScream: What the original Faceless Man did to Larry the Lark, [[spoiler:reducing him to a living decapitated head and incorporating it into a fortune-telling booth, then abandoning him in a deserted nightclub for ''decades'']].
* AnthropomorphicPersonification: The Rivers themselves, and the BigBad of book one.
* ApronMatron: Mama Thames is this for the London Rivers. Peter's own Mum as well.
* ArsonMurderAndJaywalking: In book one, Isis swears on her true name, her husband's life, and the future prospects of the Oxford Rowing Team that Peter will be safe.
* AssholeVictim:
** The would-be rapist whose victim has a VaginaDentata. No efforts are spent in trying to confirm this though.
** All the other victims in ''Soho'' fall squarely into this trope too.
* AttentionDeficitOohShiny: Leslie claims Peter is too easily-distracted to be a street cop. In his defense, Peter argues that if he were as focused as she'd like, he'd overlook ''vestigia'' and other subtle hints of the uncanny.
* AwfulTruth: Whatever it was Nightingale saw and did at Ettersberg (now known as Buchenwald).
* BattleDiscretionShot: When Nightingale faces the Night Witch, [[spoiler:Lesley and Peter have to take cover behind a Range Rover. They catch the roof of a barn literally blowing off the top, before the whole thing comes down. Shortly after that, a nearby house gets torn in half. Since they don't really get to see much of the action, just the after-effects and then the aftermath, it's almost like an in-universe OffscreenMomentOfAwesome]].
* BazaarOfTheBizarre: The Goblin Market, which also functions as a bar/social club.
* BeastlyBloodsports: Not shown, but the Faceless Man's Mooks in ''Broken Homes'' operated a dog-fighting ring. [[spoiler:Their boss used the animals' painful deaths, and the animal-ghosts they generated, to power his demon traps]].
* BeautyIsNeverTarnished: An ''extreme'' aversion with Lesley, whose beautiful face ''literally'' falls off at the end of the first book. As of book 3, reconstructive surgery has restored her speech and ability to eat solids, but she still wears a mask to avoid grossing people out.
* BeneathTheEarth: ''Whispers Underground'' eventually introduces us to [[spoiler:"The Quiet People"/"The Whisperers" a society of fair folk who live underground]], also there is a ''literal'' underground nightclub in an old military bunker frequented by members of London's magical society.
* BeethovenWasAnAlienSpy: Sir Isaac Newton was the founder of English magic. Historical figures like Dr. Polidori were Newtonian magicians.
* BigBad: [[spoiler:Mister Punch]] in book one, the Faceless Man from book two onward.
* BigDamnHeroes: Beverly has to be the BDH in ''Foxglove Summer'', when Peter had expected Nightingale.
* BigEater: Zachary from book three.
* {{Bishonen}}: Inexplicably, Nightingale is turned into one of these on the [[http://temporarilysignificant.blogspot.co.uk/2013/05/japanese-cover.html Japanese]] [[http://i.imgur.com/2aMXbwo.jpg covers]].
* BittersweetEnding: Sure the BigBad[=s=] get stopped, but book one ends with Lesley's face falling off, book two ends with the [[spoiler:suicide of Peter's love interest and her sisters when they realise [[WhatHaveIBecome what they are]]]].
* BlackComedy: Very much in evidence throughout, as police officers' sense of humour tends to this (which is TruthInTelevision). DC Trollope's version of ArsonMurderAndJaywalking being a prime example.
* BlackEyesOfEvil: Molly gets these when she nearly attacks Peter after the hemomancy rite.
* BlackMage: During World War II, the Russians created all female squads of these called the [[spoiler:Night Witches.]] One of the surviving members shows up [[spoiler:in the fourth book to have the a wizard vs. wizard duel with Nightingale, which is coincidentally the first time readers get to actually see the man cut loose. He's apparently so good that the Night Witch herself is impressed at the end of it all]]. The Germans had squads called Werewolves to combat enemy magicians. They were magic users themselves, but may or may not have been actual werewolves.
* BodyHorror:
** The victims of [[spoiler:Punch]] in book one.
** Those of the Pale Lady surely qualify, at least for [[spoiler:male]] readers.
* BookcasePassage: Not a bookcase, but there's an equally-cliché secret door into the [[spoiler:subterranean navvy community]] in ''Whispers Under Ground''. Played with when Peter presses a convenient brick simply to get the clichéd notion it'll open the door out of the way, and is amazed that it ''actually works''.
* BreatherEpisode: In ''Foxglove Summer'', the ongoing arc is lightly pushed to one side as Peter heads out of London to deal with some countryside hijinks before receiving an ominous message near the end to say the arc elements will kick back in for the next book.
* BritainIsOnlyLondon: Well, London and Thames Valley. Lampshaded in ''Moon Over Soho''; Nightingale tells Peter that there's more to life than London, and Peter replies "People keep saying that, but I've never actually seen any proof."
* CallBack: When [[spoiler:Lesley demonstrates that she's taught herself to cast a werelight]] at the end of ''Moon Over Soho'', Peter's response is almost word-for-word what he said in ''Rivers of London'' when [[spoiler:he first successfully cast a werelight himself, only with the pronoun changed]].
* CannibalClan: Peter and Nightingale spook each other by speculating they might find one of these in ''Whispers Under Ground'', mostly because they'd both seen the same schlock-horror movie about subterranean cannibals. [[spoiler:Subverted, because the subterranean-adapted navvies raise albino pigs and get Tesco deliveries instead.]]
* CardboardBoxes[=/=]FruitCart[=/=]SheetOfGlass: Peter wishes that he ''could'' be lucky enough to encounter such obstacles while "going blues and twos" to a crime scene, instead of multi-ton street-sweeping machines or idiot drivers who won't heed the siren and get out of the way.
* CatGirl: Mentioned in ''Soho'', as well as a Cat''boy'', who is more 'western', being covered in fur from (at least) the waist up, and has a decidedly feline face. The fact that they are a {{Fetish}} for some people is [[BestialityIsDepraved deconstructed]].
* TheCavalry: Nightingale has to play this in book four when Peter and Lesley get captured. He really [[TheGlovesComeOff lets rip too]].
* CelebrityResemblance: Peter gets teased for looking like UsefulNotes/BarackObama.
* ChangelingTale: ''Foxglove Summer'' [[spoiler: begins with a missing child case that is eventually revealed to be one of these thanks to the TheFairFolk.]]
* ChekhovsGun: The ''E. coli'' outbreak from ''Whispers''.
* ChildrenAreInnocent: The Ghost Magistrate doesn't see the harm in wife beating, but harm a child and he is a HangingJudge.
* ClassyCane: Nightingale has a silver tipped cane which he is rarely without.
* {{Cliffhanger}}: Book four ends on one with [[spoiler:Lesley's defection to evil]].
* ColdIron:
** Mentioned to be a problem for the river folk in ''Moon Over Soho'', when one of them gets an iron railing straight through him.
** Further upheld in ''Foxglove Summer'', where [[spoiler:Peter uses a staff with an iron cap to wound a unicorn]].
* TheConsigliere: Oxley is this to Father Thames. Tyburn would like to be this to Mama Thames, but comes across as closer to TheStarscream.
* CoolCar: Nightingale's classic Jaguar (a Mark 2 [=XK6=]) and Beverly Brook's new MINI.
* CompellingVoice:
** Lady Ty.
** The Faceless Man.
** Punch, while on stage at least.
* CordonBleughChef: Molly's culinary experiments in book four leave a lot to be desired, like edibility or actually knowing what it's made from.
* CoversAlwaysLie:
** The blurb on the UK version tries to sell the book as a Literature/HarryPotter clone. Anyone who bought the book on the basis of that is in for a shock. The US version has its own problems, downplaying the whimsical aspect of the novels and selling them as thrillers.
** The blurb on UK version of ''Whispers Underground'' gives the impression that Agent Reynolds' "deep religious beliefs" are going to cause her to come to blows with Peter. In the book itself, her religious beliefs are mentioned twice: When she asks Peter not to take the Lord's name in vain and when, at the end, she's mentioned to have found a local evangelical family to spend Christmas with. Neither has any impact at all on the plot.
*** The Del Rey edition is even worse, calling her "a born-again Christian who regards all magic as the work of Satan", although there is zero evidence of this in the book.
** The Del Rey covers not only turn self-confessed nerd Peter into a ScaryBlackMan silhouette, but it also has him wielding a pistol: something he, like most British police, isn't authorized to do except under special circumstances.
* CreatorProvincialism: Ben Aaronovitch has admitted on his site and in his Author descriptions to absolutely adoring London and not wishing to live anywhere else. Peter is very much in the same mold, some people do try to call him out on this however.
* CriticalStaffingShortage: The Folly, the police division supposed to be responsible for all of Britain's magical law enforcement, is down from its full divisional strength to a single officer, raising to three and back down to two again over the course of the series. This has left London (and presumably the [[BritainIsOnlyLondon rest of the UK]]) at serious risk, due to infighting by the various {{Anthropomorphic Personification}}s, dangerous magical criminals like the Faceless Man, and the {{Masquerade}} starting to fall apart, as they are unable to even respond properly much less anticipate magical crimes.
* CruelAndUnusualDeath: In the fourth book, a man is burned alive from the inside out. His bones end up catching fire, his eyes are boiled, his mouth his charred, but his clothes are unharmed.
* CuteMonsterGirl: Molly the Maid. Mostly human looking, but has a snake like tongue, a smile that is just a bit too wide and too full of razor sharp teeth.
* DeathGlare: Given by Tyburn after Peter blows up her fountain, trashing her garden.
* DeadpanSnarker: Something of a calling card for the Faceless Man. He leaves sarcastic messages on magical landmines in Elvish and, in ''Foxglove Summer'', [[spoiler:leaves a literal card for Nightingale - after he tracks down the location of a phone call, all that's in the house is a "With Sympathy" greeting card with "NICE TRY" written inside it]].
* DebateAndSwitch: At the end of ''Soho'' [[spoiler:Simone and her sisters are revealed to be inadvertently feeding off of other people's lifeforce to stay alive. Nightingale is for summary execution as per historical treatment of similar creatures. Peter says [[InhumanableAlienRights they have rights under law]], Nightingale counters that it would blow the {{Masquerade}} wide open to go through the courts, and it looks like they have a major dilemma on their hands. Then the sisters commit suicide because they cannot live with the revelation]] solving everything neatly.
* DemonicPossession: The MO of the BigBad from book one.
* DeskJockey: Peter's fate before meeting Nightingale was to be assigned to one of the Metropolitan Police's paperwork divisions.
* DestructiveSaviour: Peter. This runs from the mundane, like hijacking an ambulance and causing twenty thousand pounds worth of damage, to the magical, where Nightingale jokes that Peter's ''[[CallingCard signare]]'' is the tendency to [[MadeOfExplodium make things explode]].
* DiscreetDiningDisposal: Toby's tendency to waddle can be traced to this trope, as Molly tends to cook much too much and has LethalChef tendencies.
* DomesticAbuse: The Ghost Magistrate is fine with this, all women are shrews after all.
* DoNotCallMePaul: Tyburn? That is Lady Ty to you, peasant.
* DontBeRidiculous: Agent Reynolds' reaction to Peter and Kumar [[CasualDangerDialog discussing whether their current experience is more like being a bobsleigh team or the luge]].
* DownerEnding: In ''Broken Homes'', [[spoiler:Lesley betrays Peter in order to join the Faceless Man, so that her face can be restored.]]
* EaglelandOsmosis: In ''Foxglove Summer'', Peter is irritated when Beverly calls the police "the feds". ("The filth" is at least an ENGLISH epiphet.)
* EasterEgg: The covers of the UK editions are loaded with them with information about London, and background information on the plot, hidden in the word scrawl.
* ElaborateUndergroundBase: In book three they discover the Faceless Man was apparently planning one of these under the cover of Subway works, but they managed to discover it before he'd done more than just construct the shaft (although Peter reveals his architect training by pointing out where he was planning on hanging the floors and utilities).
* EnfantTerrible: The [[ChangelingTale changeling]] who shows up partway through ''Foxglove Summer'' is a mind-controlling brat. [[spoiler:She is subsequently revealed to be the real Nicole Lacey, who was taken as a child and replaced by a changeling - who also happens to be her biological half-sister - and has now been returned, not much the better for having been raised by TheFairFolk. Her mother drags her back into the woods to get the changeling back in return.]]
* EvenTheRatsWontTouchIt: Toby whimpers and hides when offered some of Molly's eggs Benedict.
* EverybodyLives: Aside from one unfortunate sheep, there are no deaths in ''Foxglove Summer'', although a few people wind up in hospital and [[spoiler: one of the unicorns may need a faerie vet's attention]].
* EvilHasABadSenseOfHumor: The Faceless Man. In book two, he leaves the message "IF YOU CAN READ THIS YOU ARE A NERD AND ALSO PROBABLY DEAD" written on a demon trap in [[Literature/TheLordOfTheRings Tolkien]]'s elvish script. In book four, he leaves a note on a time bomb warning that it is booby-trapped and should not be tampered with "as being blown up often offends".
* FaceHeelTurn: At the end of book four it is revealed that [[spoiler: Lesley is working for the Faceless Man when she tasers Peter to help him get away. Disturbingly we have no idea for how long she has been a double agent, but the victim at the start of the book was killed as part of the Faceless Man's research into magically creating a new face for her]].
* FairCop: Lesley May in the first book, prior to her injuries.
* FertileFeet: In an earthy variation, wildflowers blossom overnight at the spot where Father Thames won the literal pissing contest in book four.
* FictionalSport: Nightingale's old schoolmates played an ''impello''-based version of dodge ball that they called Indoor Tennis. Peter and Lesley, naturally, call it Pocket Quidditch.
* FirstPersonSmartass: Peter is the narrator of the books and is a self-admitted smart-ass, although he is slowly learning how not to be.
* FoodChains: One constant rule of this Verse is that eating or drinking what another magic-touched being provides obliges you to obey them, unless they absolve you of that obligation beforehand. Granting that exemption to guests is a key part of demimonde etiquette, and Peter is nearly ensnared by Lady Ty in this fashion.
* {{Foreshadowing}}:
** In book three [[spoiler: Peter catches a glimpse of Lesley taking off her mask and showing Woodville-Gentle her face]]. At the time Peter assumes it was just as part of a distraction, but in book four [[spoiler:Lesley shows that she has switched sides on the promise of Woodville-Gentle's student "The Faceless Man" fixing the magical damage. That scene was clearly an early consult]].
** Book four also foreshadows this when both Peter and Lesley are taken prisoner and the {{mooks}} are getting ready to kill them; [[spoiler: Lesley uncharacteristicly joins Peter in begging the guys to call their boss, with her voice noted as having urgency in it. Its clear she has already switched sides at that point, or at least has been given the offer]].
** In a subtle example from book one, [[spoiler: Leslie doesn't have to ask whom the 18th century actor Mr. Punch has a grudge against was, even though she's already shown herself to be quite uninterested in London's cultural history. This is an early sign that she's possessed by Punch himself.]]
* FunWithAcronyms: The mnemonic for first-officer-on-the-scene-of-a-disaster is SAD CHALETS. "Survey; oh god there's a bomb. Assess; oh god there's more than one bomb and everyone in the tower will die. Disseminate; oh god there's a bomb, we're going to die, send help."
* GasLeakCoverUp: D.C.I. Nightingale has an arrangement with the Metropolitan Fire Brigade for when he has to KillItWithFire. The fire brigade will have appliances on hand to make sure the blaze does not get out of hand, and the fire inspector will write the fire off as the result of 'faulty wiring' or something similar.
* GenderReveal: Ash Thames discovers during sex the woman he picked up in a bar in ''Soho'' is a very convincing crossdresser. It turns out not to bother him, he was having too much fun to care. Peter is more than a little discomforted by the revelation though.
%% * GenkiGirl: Beverly Brook.
* GentlemanAndAScholar: DCI Nightingale, right down to the silver tipped cane and tendency to correct other people's grammar.
%% * GentlemanWizard: DCI Nightingale again
* {{Ghostapo}}: The Ettersberg research facility the Nazis were running in WW2 involved some very horrific abuses of magic, and also human and non-human people.
** The Real Life 'Werwölfe' where fanatic young Nazis in cities just after, or about to, surrender. They went through the streets and hanged everyone who put up a white flag. In the books, they where specialists at finding practioners.
* GirlOfTheWeek: Beverly in book one, and Simone in book two. Simone [[spoiler:is more of a TemporaryLoveInterest though]], while Beverly [[spoiler:returns as a more serious love interest later in the series]].
* GrammarNazi: Nightingale corrects Peter's grammar from time to time, and gives no credence to Peter's counterargument that colloquial speech ''is'' the standard style nowadays.
* GrandTheftMe: [[spoiler:Ghost Henry Pyke by way of Mr. Punch does this to Lesley]] for most of the first book.
* GratuitousGerman:
** Used by Peter to a German family who get trapped in the middle of the riot.
** More prominent in ''Broken Homes'', dealing with the Old German Magicians at Weimar. (Alas, the German is severely broken too.)
* TheGreatBritishCopperCapture: In book four we essentially get the magic version when Peter and Lesley are taken prisoner by the Faceless man's {{mooks}} and [[TheDragon Dragon]].
* HalfHumanHybrid:
** Created by Black Mag....[[InsistentTerminology Ethically Challenged Magic]] in ''Soho''.
** Zachary from ''Whispers'' is part fae (although Peter speculates that the fae are in any case an offshoot of humanity whose ancestors were permanently altered by magic).
** In ''Foxglove'', [[spoiler: Derek]] is the changeling's biological father, who'd presumably had a liaison with one of TheFairFolk.
* HiddenDepths: Nightingale may look like an OfficerAndAGentleman, but he once personally destroyed ''two'' [[CoolTank Tiger]] tanks by himself (to put it in perspective, Peter has difficulty in burning through a paper target).
* HorrorHunger: Implied to be why Molly nearly eats Peter after the [[{{Whatevermancy}} hemomancy]] rite in the first book.
* HumanSubspecies:
** Peter speculates that [[spoiler: the Quiet People]] are this in ''Whispers Underground'', although the question isn't really settled.
** By the time ''Foxglove Summer'' rolls around, Peter has begun to formulate some theories about how magic may be causing some new human speciation.
* IdTellYouButThenIdHaveToKillYou: Peter tells another policeman who asks the truth about the supernatural: "I could tell you, but then you'd have to section me."
* IdiosyncraticEpisodeNaming: The chapters of ''Moon Over Soho'' all have the titles of classic jazz songs.
* ImperialStormtrooperMarksmanshipAcademy: Trope [[DiscussedTrope name-checked]] by Peter in book three to describe how an automatic paintballing machine in the shooting gallery fires erratically.
* ImprovisedWeapon: The murder victim from ''Whispers'' was stabbed to death with a shard of broken plate.
* InfantImmortality:
** Nightmarishly averted within the first few chapters of the first book, just to give the reader an impression of the kind of ride they're in for.
** Discussed in ''Foxglove Summer'', where it is considered a sad fact, that with disappeared children, few people expect to find them alive after a day or so.
* InsistentTerminology:
** When Peter and Nightingale discover they're up against a black magician in book two, Peter points out that the term "black magician" is problematic, particularly since Peter is of African descent and is thus, in a sense, himself a black magician. Thereafter he uses variations on "ethically challenged magical practitioner" instead.
** Zack gets offended when Peter calls him a goblin, grumbling that people who don't know what it means shouldn't call other people that.
* InstantSedation: Peter wants something that does this, Dr Walid explains there is no such thing (although he can come up with something that will work reasonably quickly at the expense of common sense and basic safety). That would be [[http://en.wikipedia.org/wiki/Etorphine etorphine hydrochloride]] -- an opioid derivative a thousand times stronger than morphine, commonly used as a general anesthetic for large animals and perfectly capable of causing fatal respiratory arrest in very small doses. Dr Walid helpfully supplies Peter with auto-injectors of Narcan (an opioid antidote) as well as a card to give paramedics in case of accidental exposure[[note]]"Warning. I have been stupid enough to stick myself with etorphine hydrochloride, the following is the list of heroic measures that will be necessary to save my life..."[[/note]]. Treated quite sensibly as the officer he's forced to stick with it--who is considerably heavier than the target he expected--still ends up on sick leave for six months afterwards.
* InterruptedSuicide: Mama Thames tells Peter that her decision to jump into the river was repeatedly delayed by how unsuitable she found one bridge after another. Also, the would-be "one-under" who kept having to wait because he wouldn't jump in front of a Tube train if any kids were around to see.
%%* JerkAss: Tyburn, oh is she ever. And A ManipulativeBitch to boot.
* JerkWithAHeartOfGold: Peter, in the first couple of books, is rather a shallow jerkass, albeit one who wants to do the right thing. By later books he has begun to start taking things rather more seriously and is somewhat more insightful.
* JurisdictionFriction: Averted. Peter notes that unlike in the media, the police services all work fairly well together and do not get possessive over high-profile cases. If anything, the opposite is true, police departments will actively work to transfer responsibility to other departments because of the massive cost and time involved in murder investigations so that it doesn't come out of their budget.
%% * KnightInSourArmor: Peter again.

[[folder:Tropes L to P]]
* LandOfFaerie: Exists in the "Alternate Dimension" form. ''Foxglove Summer'' deals with the problem of Fairyland getting a little too close to our own dimension. At the end of the book [[spoiler: Peter almost gets stuck there, having traded himself in exchange for a hostage]].
* LastOfHisKind[=/=]ThereIsAnother: Nightingale ''thought'' he was the last active master Newtonian practitioner in the UK. Then Peter ran into the Faceless Man...
* LateArrivalSpoiler[=/=]FirstEpisodeSpoiler: It is increasingly hard to talk about PC Lesley May after the end of book one without giving away the conclusion.
* LesbianCop: Detective Sergeant Stephanopoulis, described as a "terrifying lesbian". She's also an OldFashionedCopper and the only joke ever told about her sexuality is "do you know what happened to the last sod who made fun of Stephanopoulis? Neither does anyone else, they haven't found the body yet".
* LethalChef:
** Molly acquires more than a bit of this trope in book two. As long as she is cooking traditional Victorian style food she is top notch, but when she tries branching out into anything else it all goes a bit wrong.
** Peter's mother also qualifies on the grounds that she believes that anything that is not on the verge of spontaneous combustion does not have enough chili peppers in it.
* LivingMemory: Ghosts are apparently memories and personalities imprinted on the residual vestigia of a location, rather than the actual disembodied souls of dead people. They gradually fade over time as the vestigia dissipate, suffering GhostAmnesia and eventually disappearing entirely.
* LosingYourHead:
** The unfortunate Larry The Lark, head chopped off, [[DecapitationPresentation served up]] on a silver platter at a banquet in the sixties...and still kept alive by ethically challenged magic until the conclusion of ''Soho''. Just to add to the HumiliationConga it was dressed up in a turban and used as a fortune telling machine.
** Victims of Mr Punch tend to suffer this as well, though it's a fifty/fifty chance whether you'll have your head whacked off by blunt trauma or [[YourHeadAsplode blown apart by magic.]]
* MadLibsCatchPhrase: Peter, narrating, will occasionally come out with a surprisingly erudite bit of historical knowledge, always followed by "I knew all this because..." ...it was on a plaque he read once to relieve the boredom of guard duty. Or ...Nightingale makes him read Tacitus in the original Latin as part of his magic homework. Or it came up while he was watching ''Series/DoctorWho'' or playing D&D as a kid.
* TheMagicGoesAway: Subverted in-universe: Nightingale and his surviving colleagues ''thought'' magic would fade away in the wake of Ettersberg, and it did weaken for a couple of decades. Then it started coming back [[spoiler: and seems to be rising faster as of book four.]]
* MagicAIsMagicA: Described in minute detail.
* TheMagicComesBack:
** Magic was believed to be declining after the events of World War II. Apparently it's been making a comeback since the 1960's.
** In ''Broken Homes'' it seems this process is accelerating. Particularly given the conclusion where [[spoiler: a massive magical collection device is discharged over London]].
* MagicStaff:
** [[spoiler:Nightingale's cane is one.]]
** The fourth book reveals that they used to be forged by an order called the Sons of Weyland, but the order no longer exists and [[spoiler:Nightingale]] may be the only one who knows how to make one now -- in England at least. They can be used to store up magical energy that a magician can call upon when he needs it.
** In ''Foxglove Summer'', [[spoiler:the Sons of Weyland get namedropped by a retired wizard living in the country, and he bequeaths to Peter his old staffs.]]
* MagicVersusScience: Magic is an EMP type here. Notably it has the same effect on human brains as it does on technology, just electrical technology is more sensitive and will short out before your brain does. The novels as a whole avert this though. The organised study of magic originates in the setting with Isaac Newton, and Peter frequently attempts to fit magic into an empiricist, rationalist framework. Magic shorts out modern technology not because [[Literature/TheDresdenFiles magic is inimical to modern science]] but because, it is speculated, modern culture has made technology [[PostmodernMagic quasi-magical in itself]].
** In ''Foxglove Summer'', Peter figures out a way to utilise it. Using cheap microprocessors and LED lights, he is able to craft a makeshift magic detector -- when the light goes out, magic is present.
* MakingASplash: The Rivers can control their respective watercourses' flow, both consciously and as an unconscious effect of their emotional state. Beverley Brook calls up a flood to extinguish the Covent Garden fires. [[spoiler: Nicky is implied to have drowned one of book four's tree-cutters on dry land, to avenge Sky.]]
* MaleGaze: The books are from Peter's perspective so it's [[JustifiedTrope Justified]].
* MarketBasedTitle: Book one was re-titled as "Midnight Riot" for the US release, ostensibly [[ViewersAreMorons because American readers need something more dynamic]] to catch their interest.
* {{Masquerade}}: As per standard in this genre, created more through public indifference and traditional discretion. As of book four it is becoming increasingly shaky though, and may not be sustainable for much longer.
* MegaNeko: The Ethically Challenged Magician creates ''real'' catgirls and catboys.
* {{Meido}}: Molly, always wears the full Edwardian-Victorian maid outfit, and to quote the narration in ''Moon Over Soho''.
-->''Molly glided into the room like the winner of the all-London Gothic Lolita competition.''
* TheMenInBlack: Technically The Folly should be this, but Nightingale hasn't been up to much for years, Peter isn't too keen on the idea of institutional secrecy, and [[spoiler:Lesley was a bit too brash and indiscreet in her methods]].
* MerlinSickness: Nightingale was born in 1900, aged normally until the 1970s, and then for reasons that are still not clear began getting younger again. The effect is only on his biological age, however; his memory works normally. [[spoiler: The fourth book reveals that he's not the only one this happened to.]]
* MistakenForGay: When Peter meets Nightingale for the first time, he thinks that all the man is lacking to complete the image is a "slightly ethnic younger boyfriend".
* MuggingTheMonster:
** Sending a skinhead around to collect a debt might have worked if the person he went to intimidate wasn't a goddess capable of mind controlling him.
** And then there was the AssholeVictim who tried to rape the Pale Lady, only to be introduced to the VaginaDentata trope...
* MundaneSolution: Villain example when [[spoiler: Punch decides to [[WhyDontYaJustShootHim just shoot]] Nightingale]].
* MyGrandsonMyself: Mention is made in ''Moon Over Soho'' of Nightingale having pretended to be his own son in order to attend an old colleague's funeral without raising awkward questions. Mostly, though, he gets by by keeping to himself and not having protracted interactions with anybody who isn't part of the {{Masquerade}}.
* NakedPeopleTrappedOutside: One of the down sides of [[spoiler: Peter having sex with Beverly while floating on/in a river]] is that it's a long walk back upstream to where they left their clothes.
* NationalWeapon: Peter thinks the pickax handle should be enshrined as the traditional "cultural weapon" of the London police.
* NatureSpirit: Given the nature of the series [[spoiler: it was inevitable that an actual dryad would show up in the fourth book albeit as the spirit of a plane tree.]]
* NerdsSpeakKlingon: Peter puts a copy of a Tolkien-Elvish phrase he'd found on a magical booby-trap on the Internet and asks for a translation. ''[[Literature/TheLordOfTheRings Lord of the Rings]]'' fans quickly come up with the English version, which says that whoever is reading it is both a nerd and lucky not to have been killed.
* NoNameGiven: Mama Thames claims she no longer ''remembers'' her name as a mortal woman.
* NoSell: Repeated exposure to various forms of mental influence has given Peter enough resistance to ignore it. At least from a less experienced user.
* NoodleImplements[=/=]NoodleIncident:
** Whatever happened to Peter and Leslie during their probationary training, that involved "the dwarf, the showgirl, and the fur coat".
** "The Home Crowd Advantage", after mentioning the events of previous books as reasons why Peter is ''not'' part of the police presence at the 2012 Olympics, adds "the thing that happened in Kew that was totally not my fault."
* TheObiWan: Nightingale fulfils this role to Peter. Although he verges on ObsoleteMentor a couple of times, especially when it comes to modern police methods, and this is a particular bone of contention at the end of ''Soho'' when the issue of InhumanableAlienRights and due process through the courts, versus just killing sentient non-human possible criminals comes up.
* ObliviouslyEvil: The ghost of Henry Pyke [[spoiler: doesn't seem aware that the people harmed by Mr. Punch's antics are being hurt for real, not just pretend]].
%% * OldFashionedCopper: DCI Seawoll.
* OurVampiresAreDifferent: Vampires suck the life force out of their surroundings with their mere presence. They do also hunger for blood, but nobody knows why. Vampirism is some form of infection -- once one person in a family becomes a vampire, everyone else quickly follows -- but the vector for the transformation is unknown. On the whole, there is a lot that is not known about vampires, because they're so dangerous that whenever one is encountered a sensible person will KillItWithFire as soon as possible, and not mess about trying study it. Apparently there was some research by the {{Ghostapo}} into using vampires as living weapons in World War II, but no one wants to talk about it as it apparently went rather wrong.
* PerceptionFilter: Possessed by the BigBad of ''Soho''.
* PersonalRaincloud: Nightingale creates one that follows Peter around for half an hour, after Peter complains about only being taught basic spells and never getting to see any really elaborate magic.
* PoliceBrutality: A mild example, but Lesley has a distinct preference for threats of violence and can be counted on to suggest the most direct and violent course of action in any situation.
** Peter jokes about this trope from time to time, as when he describes one of the police-baton moves he's been trained in as the sneaky one that won't look so obvious on the news footage.
* PoliceProcedural: The books are as much procedural as they are UrbanFantasy. Only the coppers have to not only apply the law of the land to the non-human community same as they would with regular humans, but also maintain the {{Masquerade}} too.
* PopCulturedBadass:
** Peter makes a ''lot'' of GenreSavvy references to movies, ''Series/DoctorWho'', and various fictional wizards. His associates aren't bad at these, either.
** Even the Faceless Man drops a Tolkien reference in the inscription on a demon trap.
* PopCulturalOsmosisFailure:
** Nightingale doesn't really get Peter's Literature/HarryPotter namedrops.
** Invoked and averted when Peter thinks he's going to have to explain to Stephanopolos what [[Literature/{{Discworld}} Unseen University]] is, but she tells him her partner is a Creator/TerryPratchett fan.
* PortentOfDoom: ''Foxglove Summer'' sees [[spoiler:Lesley make contact with Peter again. Initially, it's just through text messages but, towards the end of the book, she calls. They have a brief conversation in which Lesley tells Peter they've got about a year until things really kick off, but gives absolutely no detail on what said things actually are.]]
* PostModernMagik: While magic itself will to destroy any technology equipped with a microprocessor, it's not uncommon to find supernatural beings who have embraced the modern world. So far we've seen:
** Local goddesses with mobile phones, university degrees, and Wikipedia pages.
** The equivalent of dwarves who carry Sten guns, wear sunglasses and donkey jackets, get their groceries from Tesco, and are fond of the music of Queen.
** Technologically savvy magicians using the internet to translate parts of grimoires.
** Certain modern plastics hold magic residue nearly as well as stone does.
** [[spoiler: [[CatGirl Cat girls]] created with magic and possibly with the assistance of modern science as well.]]
** One of Nightingale's school chums speculated about whether a ''GeniusLoci'' could emerge within the subway system or telephone network.
** The fourth book introduces [[spoiler:a council estate that contained a device for capturing magical energy and also had a dryad living in its copse of plane trees]].
* PowderKegCrowd: The patrons at the Royal Opera. Mr. Punch, mind-controlling several police officers via the ghost of Henry Pyke, incites the crowd to riot and burn down most of Covent Garden.
* PoweredByAForsakenChild: The Demon Traps. Essentially magical landmines powered by a tormented ghost.
* PreventTheWar: In the first book, the B-Plot is that the two {{Anthropomorphic Personification}}s of the Thames, and their families, are gearing up to go toe-to-toe with each other (with the implication that it will be very unpleasant for everyone living in the Thames valley, estuary, and catchment area) and our heroes need to find a way to force a truce.
* PsychicAssistedSuicide:
** The BigBad of ''Soho'' tries this on Peter to force him to jump off a roof.
** Tyburn tried something similar in book one to try and force Peter to drink from her fountain to put himself in thrall to her. [[spoiler:The practice he got in then helped him resist the bad guy of ''Soho''.]]
** It pops up again [[spoiler: in the fourth book where a man is apparently made to jump in front of a train.]]
* PutOnABus: [[spoiler: Beverley Brook]] at the end of book one. Comes back in book four.

[[folder:Tropes Q to Z]]
* RailroadTracksOfDoom: The ghost of a teen who got hit while tagging the inside of a rail tunnel appears briefly in ''Whispers''.
* ARareSentence: In ''Foxglove Summer'', Dominic comments that he can't believe he's saying things like, "Do we actually have an operational plan for dealing with the unicorns?"
* [[ViewersAreGeniuses Readers Are Genuises]]: The books are best read with an A-to-Z of London to one side, and a copy of ''[[http://www.bartleby.com/81/ Brewer's Dictionary of Phrase and Fable]]'' to the other. There is a lot of detail and you will need to keep up.
* RememberWhenYouBlewUpASun: Thomas "Tiger Tank" Nightingale once took down two of the aforementioned vehicles during the second World War. Considering that Peter has trouble aiming properly at paper targets, and can at most burn through a door, the tank thing is pretty damned impressive, and Peter makes sure that the reader knows it.
%%* RichBitch: Tyburn.
* RooftopConfrontation: The climax of ''Soho'' and the climax of ''Broken Homes'' both take place on different rooftops.
* RunningGag: People whom Nightingale or Peter are telling about the supernatural for the first time promptly ask if ''aliens'' are real, too. (When Peter himself asks his new boss this, Nightingale says: "Not yet".)
* SarcasticConfession: In book three Lesley sarcastically says to create a distraction for Peter to snoop around she'll take her mask off. When Peter catches a glimpse while snooping, [[{{Foreshadowing}} she actually]] has.
* SavvyGuyEnergeticGirl: Peter is generally a quiet, thoughtful type who takes a scientific approach to magic and a community-based approach to police work. Lesley is much more gung-ho.
* ScarsAreForever:
** Lesley's horrific injuries at the end of ''Rivers'' do not get any better in ''Soho''. As of book 3, she's getting better at letting people see her without her mask, but things have not improved much. In ''Moon Over Soho'' Nightingale is still suffering from his wounds from the previous book too, keeping him firmly in the background and as support.
** Oberon - despite being some sort of Fae - still bears the scars from his days as a slave a few hundred years ago.
** In book four, [[spoiler: Lesley is revealed to have become TheMole for the Faceless Man, and it's implied that she expects him to subvert this trope and restore her face.]]
* SceneryPorn: Aaronovitch's prose is detailed enough to make this a literary example. Peter trained as an architect (but his draughtsmanship was too poor to cut it) thus why Peter tends to go on about buildings so much.
* ShootingGallery: The Folly has one for trainee wizards to practice their fireball skills in. As a mark of just how long it has been since it was put to use, all the target silhouettes are still shaped like WW 2 Nazis.
* ShoutOut:
** When Peter asks what the collective noun for wizards is, Nightingale says it's a coven and Dr Walid jokes that it's actually "[[{{Discworld/Wintersmith}} an argument]]".
** The graffiti artist in ''Whispers Under Ground'' is interrupted in the middle of writing "[[Film/BillAndTed Be Excellent To Each Other]]".
** The beer at the nazareth in ''Whispers Under Ground'' is called "Mac's" and from a microbrewery in the States. In [[Literature/TheDresdenFiles Chicago]], perhaps?
** There is one to the song "The Internet Is for Porn" from ''Theatre/AvenueQ'':
--->'''Leslie:''' That (finding info about a suspect)'s what the internet is for.\\
'''Peter:''' [[ComicallyMissingThePoint That's not how the song goes.]]
** In ''Whispers Under Ground'', while traversing the titular underground, Peter gets strong [[{{TabletopGame/Warhammer40000}} Space Hulk]]-vibes from the claustrophobic tunnels.
** Sergeant William Daverc "really d'Averc" = Huillam d'Averc in ''Literature/TheHistoryOfTheRunestaff''.
** In ''Whispers Under Ground'', Peter is temporarily partnered with a [[Series/TheXFiles red-headed female FBI agent]].
** There are several references to ''Series/DoctorWho'' throughout the series. Given Aaronovitch's writing history, this probably counts as an InJoke.
** Peter is at one point given a lift by someone [[Literature/GoodOmens whose car stereo only has]] ''[[Literature/GoodOmens Queen's Greatest Hits]]'' [[Literature/GoodOmens in it]].
** In ''Whispers Under Ground'', Peter sees a gang of laborers with [[Music/AlicesRestaurant shovels and rakes and other implements of destruction]].
** It's probably no coincidence that the fae call their migratory shopping district a Literature/GoblinMarket.
%% * ShownTheirWork: And how!
* SinisterSurveillance: Averted when Peter points out (TruthInTelevision) that the supposedly ubiquitous "surveillance cameras" are simply all the security cameras there are, and not linked to some Big Brother network.
* SlidingScaleOfIdealismVersusCynicism: Waaaaay down the cynical side.
* SpellMyNameWithAThe: Much of the magical community does this with Nightingale, always referring to him as "The Nightingale". As of book five, some have taken to calling Peter himself "the starling", albeit without (yet) the prestige of a capital letter.
* SpotOfTea: In book three Peter's refusal of tea when he meets The Quiet Folk sparks widespread muttering and consternation.
* SoBeautifulItsACurse: FBI agent Kimberly Reynolds dyes her hair a plain brown to avert this trope, as nobody took her seriously as a good-looking redhead.
* SocialEngineering: Peter's training has equipped him with loads of little tricks used by RealLife police officers, such as asking an unidentified person in a car for their driver's license: if you ask their name they might lie and have a right not to answer, but if they think it's a traffic issue they'll hand their card over without complaint.
* SophisticatedAsHell: Used a ''lot'', and probably inevitable in a series that combines streetwise cop-jargon with Latin-based thaumaturgical terminology in the same dialogue.
* TheStarscream: Tyburn is implied to be one of these to Mama Thames in ''Rivers'' and in ''Soho'' Nightingale confirms her status, and implies that when the inevitable clash between the two comes that it might be a good time to take a holiday on another continent.
* StiffUpperLip:
** Peter almost never narrates his own emotions, only his logical thinking and actions, and it's implied throughout the series (and spelled outright in ''Foxglove Summer'') that this narrative choice represents how he (InUniverse) represses or omits a lot of his emotional response.
** Nightingale shows his own, more classical, take on this trope from Peter's POV.
* StrawmanFallacy: In ''Soho'' when confronted with the issue of InhumanableAlienRights, Nightingale tries to make Peter concede that he is only arguing for rights for [[WhatMeasureIsANonHuman non-humans]] because the perps are attractive. Peter spots the strawman there, and says that he might not have thought to argue [[WhatMeasureIsANonCute if they were grotesque]] but that just makes him "shallow, not wrong".
* StringyHairedGhostGirl: Molly is explicitly described as looking like one when Peter first sees her.
* SufficientlyAnalyzedMagic: Started by Newton, and Peter adds his own contributions to this when he works out why Magic and Electronic Technology are incompatible. [[spoiler: ''Foxglove Summer'' reveals that David Mellenby had found a way to close the gap between Newtonian magic and quantum theory.]]
** Practically lampshaded in a summary of various eras' prevailing theories about ghosts, as each one (Peter's own included) ''very'' closely mimics whatever the cutting-edge scientific paradigm of its day happened to be.
* SuicideByCop: The antagonist in "Home Crowd Advantage" turns out to be trying to provoke Nightingale into a WizardDuel so he can commit the magical equivalent of suicide by cop.
* SupernaturalMartialArts: In ''Broken Homes'', Peter is practicing his ''formae'' and speculates that it might be possible to create one with the shape of the body, rather than using words to form a shape in your mind, and maybe that's where the idea of martial artists flying and throwing energy bolts comes from.
* SupernaturalSensitivity: A magician can sense magic as a flash of sensations. The Rivers are able to literally smell when someone is a magician, even if the magician in question isn't using magic at the time. Toby the dog is also able to sense magic. [[spoiler: The Night Witch in the fourth book says that the Germans had units of men - called werewolves - able to "sniff out" magicians. These men may or may not have been actual lycanthropes.]]
* TactfulTranslation: Madame Teng's translator in book 3 engages in a bit of this when Teng delivers a tirade about the position of Mainland China vis-a-vis Taiwan. He basically just says that its important to her that Peter knows she dislikes modern mainland China and, while Peter doesn't need to know the exact translation, can he just look interested please.
* TeamPet: Toby the Dog.
* TechnologicallyBlindElders: Nightingale knows little to nothing about the modern, computerized systems used by the police.
* ThereWasADoor: Played with by Nightingale in book four, when [[spoiler: he blows a huge hole in the front of a building, only to slip in the ''back'' door while his opponent is taking aim at the resulting dust-cloud.]]
* TheseAreThingsManWasNotMeantToKnow: [[spoiler: While not exactly, filled with the standard [[TomeOfEldritchLore Tomes of Eldritch Lore]], the Black Library contains the Nazis' documentation of their human -- and fae -- experimentation and their attempts at using David Mellenby's theories to unite magic with quantum theory. Mellenby and other British magicians killed themselves after surviving the battle of Ettersberg and the subsequent retreat back to the Allied front line.]]
* ThisIsReality:
-->"So magic is real," I said. "Which makes you a... what?"\\
"A wizard."\\
"Like Harry Potter?"\\
Nightingale sighed. "No," he said. "Not like Harry Potter."\\
"In what way?"\\
"I'm not a fictional character," said Nightingale.
* TomatoInTheMirror: In ''Moon Over Soho'', [[spoiler: Simone and her sisters turn out to be the suspected culprits that Peter and Nightingale were hunting, but with all of their own memories faded, they all had no idea.]]
* TriggerHappy: As per American law enforcement standard, Special Agent Reynolds is ''very'' quick to return fire when Peter gets shot at in ''Whispers Under Ground''. Much to Peter's dismay.
* UnbelievableSourcePlot: ''Rivers of London'' starts with Police Constable Peter Grant interviewing a witness to a murder, who happens to be a ghost. This testimony, however, will hardly stand in a courtroom, and Grant has to use it as a springboard to find evidence that will. Similar problems with magical evidence come up elsewhere in the series, but don't drive as much of the plot.
* {{Unicorn}}: Perhaps in deference to their origin, the unicorns in ''Foxglove Summer'' are ferocious. [[spoiler: They're also carnivorous, as large as draft horses, and serve the Faerie Queen.]]
* TheUnmasquedWorld: Hinted at -- it hasn't happened yet, but by the end of the third book, magic is crawling out of the woodwork at an accelerating pace and Peter Grant has reluctantly come to agree with Lady Tyburn that the Masquerade can't last much longer. (It's not so much the conclusion itself that he's reluctant about, he just hates the idea of Lady Ty being right about anything.)
* UnusuallyUninterestingName: The Folly is officially merely a part of The Economic and Specialist Crime Team.
* UrbanFantasy: It's about a 21st century cop who uses magic.
* UselessSecurityCamera:
** In ''Rivers'', the first murder is caught on CCTV, but a key event in the lead-up to it, vital to figuring out who did it and why, occurs just outside the camera's field of view.
** Justified in cases when magic fries monitoring devices.
** The fact that London's ubiquitous cameras ''didn't'' record the victim's arrival at the site of his death becomes an early clue that there are hidden passages beneath the city in ''Whispers''.
* UselessUsefulSpell: Peter comes up with one of his own by combining ''aer'' (gives you "grip" on otherwise thin air) and ''congelato'' (causes liquids and gases to solidify). Both spells are fairly useless separate, but together make a handy instant DeflectorShield.
* VaginaDentata: Possessed by the Pale Lady, whose first victim is found at the end of book one, and who plays a signficant part in book two.
* VillainyFreeVillain: Tyburn. She's a RichBitch JerkAss who really takes far too much pleasure one-upping Peter and while she might be a bit of a Starscream to her mother, her real intentions are to modernise how London (and the rest of the UK) deals with magic, get everything systematised and above board, and do away with the tangles of "arrangements" and "agreements" that have accumulated over the years. Something that Peter himself is pretty keen on, she just goes about it all in a really arsehole-ish ways.
%% * TheVoiceless: Molly.
* VomitingCop: Subverted in-Verse in book four, when Peter hurriedly steps away from a shotgun-blasted corpse with his hand over his mouth. The other police assume it's this trope, but he's actually suppressing ''giggles'' because the body's condition tempted him to make a tasteless crack about zombies.
* WasntThatFun: The youngest child of the German tourist family wants to get washed out of the burning store by Beverly's called-up waters again.
* WatchThePaintJob: That detailed description of how cool Beverly's new car is? You knew it would end up in this trope. Rioters 1: Car 0.
* WeaselCoWorker: Investigations have to be paid for. Which means that police try to dump them on other departments.
* WhatAnIdiot: An In-Universe example when Dr Walid cooks up the fast acting sedative he also gives Peter a card for paramedics to read in case he stabs himself:
-->"'''Warning''': I have been stupid enough to stab myself with etorphine hydrochloride."
* WizardingSchool: Casterbrook -- the school where Nightingale learned magic -- ''used'' to be one of these. After WWII there just weren't enough people left for it to be useful though.
* WizardsLiveLonger: Nightingale certainly does, but he seems to be something of an exception.
* WhamLine: The very last line of ''Soho''. [[spoiler: "Fuck me, you can do magic."]]
* WholePlotReference: The first book, of [[spoiler:Punch And Judy]]. It's both deliberately invoked and extremely plot-relevant.
* WorldOfCardboardSpeech: Given by Peter to Tyburn in response to her ReasonYouSuckSpeech, utterly owning her in front of her entire family including Mama Thames herself.
* TheXOfY: Book one, in the UK at least, ''Rivers of London''.
* YellowPeril: One of Nightingale's predecessors at the Folly led the bust of a reputed Chinese sorcerer and white slaver in 1911. A subversion, as it turned out the sorcerer was a Canadian white guy operating under a Chinese name.
* YouDoNOTWantToKnow: Whatever it was Nightingale found in that room during ''Soho'', Peter decides he really doesn't. All we know is that the people who exhume mass graves in Rwanda and Kosovo need to be called to process it and some of what they find is not dead (yet).
* YourHeadAsplode: Happens to one of the Hare Krishnas.
