Literature / Lockwood & Co.

"When the dead come back to haunt the living, Lockwood & Co. step in..."

A fantasy series written by Jonathan Stroud, following the adventures of a ghost detection agency of the same name. In an alternate London where the dead haunt the living, Lucy Carlyle, a talented ghost hunter recently employed at the eponymous agency, must save her new job, career and sanity with the help of her partners Anthony Lockwood and George Cubbins.

In the first book, The Screaming Staircase, a mysterious locket and a botched investigation cause the employees of Lockwood & Co. to face the threat of home and joblessness. They become heavily involved in the investigation of a nefarious crime, and the haunting of an old mansion with a dark past.

In the second book, The Whispering Skull, Lockwood & Co. are hired to supervise the opening of a mysterious unregistered grave, and get entangled in a search for an occult artifact of dark origins.

The third book, The Hollow Boy, sees London in the grip of an unprecedented outbreak of supernatural activity. Amidst the chaos, Lockwood & Co. have to cope with massive workload, dangerous ghosts and a new employee, the ridiculously efficient Holly Munro.

In the fourth book, The Creeping Shadow, Lucy is freelancing following her departure from Lockwood & Co. at the end of the previous installment. She and the team are reunited when Lockwood seeks her out to enlist her services for a tough case, but there are shady, manipulative forces at work...

The fifth book, The Empty Grave, was released on September 12, 2017. Following a dramatic revelation at the end of The Creeping Shadow, this fifth title sees Lockwood & Co. "on a perilous night mission: they have broken into the booby-trapped Fittes Mausoleum, where the body of the legendary psychic heroine Marissa Fittes lies. Or does it?"

Lockwood & Co.:
  1. The Screaming Staircase (2013)
  2. The Whispering Skull (2014)
  3. The Hollow Boy (2015)
  4. The Creeping Shadow (2016)
  5. The Empty Grave (September 12, 2017)

On June 7, 2016, Stroud stated in a Facebook chat that the fifth book of the series would be the finale. This has later been confirmed in publisher summary listings for The Empty Grave.

In September 2017, it was announced that Big Talk Productions had acquired the rights to adapt the series for television, with the company heads stating the series would be "a highly original, distinctively authored, ghost-detective show to enthrall audiences of all ages."

Lockwood & Co. contains examples of:

  • Absolute Cleavage: At the dinner party, Lucy mentions that revealing necklaces became extremely popular with the emergence of the Problem. They also make George clean his glasses quite carefully, apparently.
  • Action Girl: Lucy, as well as all the other female agents.
  • Actually Not a Ghost: The Creeping Shadow. A towering, half-transparent shadowy form which raises souls from their graves… and is actually a living man in a protective suit.
  • Adults Are Useless: Only children and teenagers are able to see ghosts, so adults must rely on them and their senses in order to deal with hauntings.
  • Alternate Universe: About 50 years prior to the start of the story, ghosts start popping up in the United Kingdom and attacking people, prompting the creation of agencies intended to fight them.
  • Ambiguously Brown: Holly Munro is described as having coffee-colored skin. Her ethnicity is never mentioned.
  • Aristocrats Are Evil: Sir Rupert Gale.
  • "Awesome McCool" Name: Lockwood's old mentor, "Gravedigger" Sykes. His first name was actually Nigel.
  • Badass Longcoat: Lockwood tends to wear long coats, one of which you can see on the cover. Of course, Reality Ensues where his coat ends up getting caught in things.
  • Before the Dark Times: Before the first emergence of The Problem, the world here was relatively normal and much like our own.
  • Big Eater: George.
  • Big Bad: Marissa Fittes, who is actually responsible for the problem in the first place, along with her Dragon Ezekiel.
  • Bitch in Sheep's Clothing: Penelope Fittes.
  • Black Market: Following the onset of The Problem, any and all historical artifacts were shunned as potentially dangerous items from which ghosts might arise. Over time, however, there emerged a shadowy black market of people interested in collecting these objects and relic-men in the business of acquiring them and selling them to the highest bidder.
  • Blind Without 'Em: George is extremely short-sighted. This actually saves his life when presented with the Artifact of Doom.
  • Body Horror: The symptoms of someone who is touched by a ghost: their bodies swell and turn blue. They die very quickly if not given immediate medical attention, a fate that Lockwood avoided but Fairfax did not.
  • Book Dumb: Not overtly stated, but Lucy sometimes has trouble with "big" words. Giving that she is of working class background and has been working as a full-time agent since she was eight, she probably didn't have much time for formal schooling.
  • Ghost In A Jar: The ghost-jar that George tinkers with. Unlike other contained Sources, the Source in the ghost-jar is active and likes to taunt and scare the people who look at it. At the end of the first book, a small leak on the ghost-jar allows it to be able to talk to Lucy. In the following books Lucy uses her connection with the thing for information.
  • Bread and Circuses: Used almost word-to-word by the head of one of the major agencies while explaining the rationale for throwing a huge festival in the middle of one of the worst ghost crises ever.
  • Broken Bird: Flo Bones, after an incident that killed the rest of her agency (well, all two of them, but still) and had her fending for her life throughout an entire night against grotesque ghosts. Lucy and Holly avert this: while also being Sole Survivors of incidents that killed their entire teams, neither are particularly broken and they deal with the trauma on their own terms.
  • Buried Alive: In the third book, it turns out that all the remaining inmates of the notorious King's Prison, which was demolished circa the 16th century, were sealed under it when it was toppled down instead of being driven out as everyone thought. Their ghosts are understandably pissed off.
  • The Charmer: Lockwood, which is why George and Lucy somehow find themselves still sticking with him, even if they give their boss a lot of flak.
  • Chekhov's Gun:
    • The locket that Lockwood and Lucy find on a skeleton.
    • The goggles stolen from Combe Carey Hall.
    • The spirit capes found at 35 Portland Row.
  • Cobweb Jungle: Spiders are attracted to ghostly activity, so a good sign that there's a ghost around is lots and lots of cobwebs.
  • Cold Iron: Iron is a common deterrent against ghosts, and is nearly ubiquitous in the world: from rapiers made from iron to charms to even mobiles for children.
  • Collector of the Strange: Lockwood's parents were this, apparently. Julius Winkman and the relic-men also cater to people who collect haunted objects.
  • Color-Coded for Your Convenience: Agents usually wear uniform jackets whose color immediately identifies the agency they belong to. Averted by Lockwood and Co., which makes many people wonder about their seriousness as an agency.
  • Combat Tentacles: Used by a shape-shifting ghost in book three.
  • Crazy-Prepared: George keeps a complete set of ghost-hunting supplies in his bedroom.
  • Creepy Cemetery: Due to the nature of The Problem, pretty much all of them. The government actually hires specialized contractors to gradually clear them out. Our heroes get a taste of it in Kensal Green Cemetery.
  • Crusty Caretaker: Bert Starkins, the caretaker of Combe Carey Hall.
  • Dark and Troubled Past: Lockwood, with more and more of it revealed every book. Technically, the only main characters who do not seem to have some traumatic backstory are George and Kipps (not that we know of, anyway).
  • Dark World: The Other Side as seen in the fourth and fifth books. A dry, frozen and dark reflection of the regular world, populated by dead people who really don't like to be disturbed.
  • Deadpan Snarker: All of Lockwood & Co.
  • Death Seeker: Lockwood shows symptoms of this by the fourth book, The Creeping Shadow. While always a bit rash, he seems to have become extremely reckless about his own safety after Lucy's departure. In the final book, The Empty Grave, Lucy herself begins to suspect as much, but is nevertheless annoyed when the skull in the jar outright confirms it in his usual snide fashion, stating that the signs are and have been obvious for anyone that cares to see them.
  • Deer in the Headlights: The "ghost-lock" power some Type Two ghosts have invoke this; victims trapped in a ghost-lock are sapped of their willpower, feel an overwhelming sense of despair, and are unable to move even as the ghost approaches them. Luckily, it can be fought off.
  • Desperately Craves Affection: One of Lucy's deepest insecurities. This gets her in trouble with La Belle Dame Sans Merci, a theatre ghost that preys on the lovesick, anxious and vulnerable.
  • Dirty Coward: Subverted and discussed with Quill Kipps. Lucy thinks so after he bolts and abandons his team in the middle of a particularly nasty haunting; later, and after she witnesses him risk his life for a fellow agent, Kipps explains his actions in a way that makes them at least understandable (his Psychic Powers faded when he reached maturity. Walking into haunted zones over and over again without being able to really see the ghosts or protect himself causes him to reach breaking point from time to time). Once he can see ghosts again, he immediately becomes borderline-Blood Knight.
  • Doppelgänger: The Fetch in the third book, which assumes the forms of people important to its victims to try and lure them to their deaths.
  • Double-Meaning Title:
    • The Hollow Boy refers both to a ghost encountered in the book and to Lockwood’s feeling of inner emptiness following his family’s deaths.
    • The Empty Grave is the Fittes mausoleum and also Lockwood’s yet-to-be-filled grave at his family’s plot.
  • Downer Ending: The ending of The Hollow Boy has Lucy choose to leave Lockwood and Co. because she feels her unique talents put the group in danger. It's enough to put George off his cake.
  • Do You Trust Me?: This is the skull in the jar's repeated inquiry to Lucy in the final book, The Empty Grave. While it takes her a while to get there, the answer is ultimately "yes," as Lucy smashes the jar, allowing the spirit within to go free, and he ultimately proves an aid in taking down Marissa Fittes and her own pet Type Three ghost, Ezekiel.
  • The Empath: Lucy has a variety of this which only applies to ghosts.
  • Evil Counterpart:
    • Joplin to George. Both are short-sighted scholars specializing on the supernatural whose curiosity tends to get the better of them; Joplin is even described as having some of George's physical mannerisms.
    • Kipps' team in the second book to Lockwood and Co. (although not really evil, just antagonistic and unpleasant). Quill Kipps, the leader who boasts his fencing skills, is this to Lockwood; Bobby Vernon, the small, physically weak agent specializing on research to George; and Kate Godwin, the token girl with the listening Talent to Lucy. Ned Shaw joins as The Brute.
    • Marissa Fittes to Lucy. Marissa tries to invoke it, to Lucy's displeasure.
    • Ezekiel to the skull. Well, evil-er, anyway.
  • Evil-Detecting Dog: Cats avoid areas that ghosts are haunting.
  • The Face: Lockwood, the socially savvy and incredibly charismatic leader of the agency.
  • Face Death with Dignity: Kipps, upon realizing he is probably not going to survive exiting the Other Side. Subverted when he does make it after all, albeit in need of urgent medical care.
  • Fair-Weather Mentor: Agent Jacobs, due in part to his own experience as a ghost hunter as a child. His negligence leads to all of Lucy's friends and fellow agents getting killed. In the trial against him he claimed not to be able to hear Lucy calling for help, or to hear any of the children screaming. Instead of returning to work with him, Lucy leaves and heads to London.
  • Fat and Skinny: George and Lockwood. Lockwood is also tall, while George is a little shorter than Lucy.
  • Fat Slob / Genius Slob: Not as bad as some examples, but George tends to leave a mess wherever he goes: dirty dishes, dropped clothes, etc.
  • Flat-Earth Atheist: Reverend Skinner in the fourth book. Already adult when the Problem erupted, he'd never seen a ghost and insists that they are an elaborate ruse, or maybe just the wind. In this world, of course, it means he's completely crazy.
  • Footprints of Muck: The bloody footprints appearing on the staircase of Ms. Wintergarden's house in the third book.
  • For Doom the Bell Tolls: One measure the British government instituted to protect their citizens, particularly in smaller towns; dusk is marked by a tolling of bells, and is a sign that people should be heading back to the safety of their homes.
  • Free-Range Children: Invoked in the agency of Lockwood & Co., which is run by just the three kids without any adult supervision. However, they are licensed—at least Lockwood is, fully, and thus acts as de facto leader—and other agencies and their clients doubt their abilities and efficiency. They are also still required to take care of adult things, like fines for damages incurred on their jobs. And, for that matter, they essentially have to live as adults, managing their own affairs when it comes to clothing, housing, food, cleaning, etc.
  • Freudian Trio: Our heroes. Lucy is the Id, sensitive to the emotions of the undead, George is the Superego, insistent on research and preparation above Talent, and Lockwood is the Ego, balancing the two and making the decisions.
  • Genre Savvy: Pretty much a survival skill for agents.
    Lockwood: What were they thinking? Who builds houses on the site of an old Victorian hospital that burned down on tragic circumstances?
    George: I know. It's almost the first rule of planning.
    • Lucy muses that one of the main dangers of staying in haunted houses is succumbing to the haunting's internal logic, causing you to forget how to act safely. This is a rather meta observation on horror and ghost stories in general.
  • Getting Crap Past the Radar:
    • Lockwood offering to "show [Lucy] through the positions..." (of a complicated rapier maneuver) followed by Lucy getting a "fluttery feeling" in her stomach. Uh-huh.
    • Mr. Saunders explaining his work in Book Two and Lockwood's reaction. AR's stands for Active Remains... of course.
    Saunders: Cemetery clearance. Part of the new government policy of eradicating AR's.
    Lockwood: Eradicating what? Sorry, I must have misheard you there.
    • Flo tells Lucy that she's too young to know what Jack Carver's "remarkable tattoos" are of. When Lucy protests, Flo tells her that if she can't guess, she's definitely too young.
    • Lockwood takes Lucy for an evening walk, and when the skull teasingly asks her how things are going between them, Lucy claims they were simply on a case. The entire exchange is loaded with innuendo.
    Skull: In my experience, graveyards can be used for lots of activities, not just ghost-hunting. [...] And don't try to tell me you were scrapping with ghosts. You didn't take any equipment.
    Lucy: We had our rapiers!
    Skull: I can tell when there's ectoplasm on a blade and when there isn't. No, you and Lockwood went for a cosy chat, didn't you? And came back with brambles in your hair.
    Lucy: Well, it was very overgrown.
    Skull: I bet it was.
  • Ghostly Chill: Naturally. A good sign of ghostly activity.
  • Gilligan Cut
    It’s amazing how quickly a fire can spread in an average suburban house.
    • From The Hollow Boy:
    "Barnes may be grumpy," Lockwood said, "but when I show him your findings, he'll act soon enough. He knows how good we are." He winked at us. "Don't worry. I know we have out differences, but there's a lot of mutual respect there. If he hesitates, I'll sweet-talk him. He won't let us down."
    "That total and utter idiot." Lockwood growled. "That mustachioed imbecile. That benighted, blinkered jobsworth. He's a clown! A fraud! An oaf! I hate him."
    "How's the mutual respect thing going?" George said.
  • Glory Seeker: The skull claims that Lockwood's self-absorption and want of fame makes him this.
  • Goggles Do Something Unusual: Near the end of The Screaming Staircase Fairfax wore a prototype which presumably let him see ghosts.
    • Confirmed in The Creeping Shadow and used by Quill Kipps.
  • Government Agency of Fiction: The DEPRAC (the Department of Psychical Research and Control) which was established in response to the Problem.
  • Green-Eyed Monster:
    • Lucy is extremely jealous of Holly Munro, due to her looks, her charisma and especially the attention Lockwood gives her.
    • When she first hears about Flo Bones, Lucy is jealous that Lockwood has a female contact she didn't know about.
  • Gross-Up Close-Up: The ghost in the ghost-jar loves pulling this on people when they take a look at it.
  • Hands-On Approach: Lockwood adjusting Lucy's rapier stance in Book Two. Cue butterflies.
  • Harmful to Minors:
    • All psychical agents are children or teens, and the job is extremely hazardous and scary. Agents falling in the line of duty is almost as commonplace as the Problem itself.
    • Before Lucy came to London, she was involved in the Wythburn Mill Incident, in which all her co-agents were killed by a dangerous Type Two ghost.
    • Lockwood's parents were killed when he was young, with their ghosts being the first he'd ever seen. Then, at the age of nine, he watched his older sister die. Talk about a Trauma Conga Line.
  • Haunted Castle: Combe Carey Hall, an old abbey that is one of the most haunted locations in England.
  • Haunted Fetter: Called "Sources" here; finding and eliminating Sources—usually what's left of the ghost's body—is the main objective in an investigation.
  • Haunted House: Basically every single house Lockwood & Co. investigates.
  • Haunted House Historian: The caretaker of Combe Carey Hall, Bert Starkins, a particularly grumpy old man. Played for Laughs when he takes the trio on a tour of the property and it seems like every single feature of the place has some gruesome story.
  • Hell Is That Noise:
    • What happens when the Screaming Staircase starts screaming.
    • Less loudly, the repeated clicking sound at the Ealing Cannibal's house. Lucy eventually recognizes it as the sound of clicking teeth.
  • Hero Insurance: Averted. Lockwood & Co. faces massive fines and the threat of eviction after burning down a haunted house.
  • Hoist by His Own Petard: Steve Rotwell ends up falling into the giant circle of Sources he created and is presumably killed by the ghosts inside it.
  • I Call It "Vera": George names a giant flare he stole "Big Brenda". After having it for about twenty minutes.
  • I'm a Humanitarian: The Ealing Cannibal from The Creeping Shadow.
  • I'm Cold... So Cold...: Said nearly word for word by a ghost that Lucy and Lockwood encounter.
  • Immortality Immorality: Marissa and the Orpheus Society seek to defeat death, but only manage to cause more death and suffering along the way.
  • Improbable Age: Justified in this universe, but even Lucy wonders how Lockwood managed to buy his parents' house with enough money left to start his own agency as a young teen.
  • I'm Standing Right Here: Lockwood has to remind Lucy and George of his presence while they're having an argument about his emotional well-being.
  • Infant Immortality: Horribly averted. Only children and teenagers can see ghosts, and so they're sent ahead of their adult supervisors and into the most danger when investigating haunted areas. Child ghosts are also rather common.
  • Ironic Nickname: Little Tom was very big in real life. The nickname causes an almost fatal confusion between him and his murderer, a teenager who appears as a small, childlike ghost.
  • It's Personal: Lockwood, once he discovers Fittes is responsible for the death of his parents.
  • Jerk with a Heart of Gold:
    • George isn't nearly as charming as Lockwood, and he has his own set of bad habits, but he does care for both Lockwood and Lucy.
    • Quill Kipps turns out to have many more noble qualities than initially given credit for. He helps Lockwood and Co. of his own accord in book three and leaves his position as supervisor at the Fittes Agency in book four because he can't bear sending others to fight for him.
  • Kill It with Fire: Fire is pretty good against ghosts, both in eliminating the actual ghost or the source, their body. A variety of white-phosphorus grenades are used quite commonly in paranormal agencies. It's later shown that the bigger agencies use a giant furnace to permanently get rid of sources.
  • Last-Name Basis: Lockwood. The only person who does call him by his first name—as "Tony"—is Kipps. Later, Penelope Fittes also starts addressing him as "Anthony".
  • The Leader: Lockwood, of the charismatic variety.
  • Lethally Stupid: Anthony Lockwood has shades of this, as he will often leap unprepared into dangerous situations, much to George's chagrin. For example, when he pushed his employees to explore Combe Carey Hall with him under ridiculously unfavourable circumstances.
  • Locked into Strangeness: People who have been to the Other Side tend to develop white flecks in their hair.
  • Magic Mirror: The bone glass, an Artifact of Doom which might or might not be a window into the world of the dead. No one who gave it a proper look lived to tell.
  • Magnetic Medium: The skull claims that Lucy is this due to her unusual Talent.
  • Master Swordsman: Lockwood. All agents carry rapiers, but he's actually good with it.
    • Turns out the one person who managed to beat Lockwood in a swordplay tournament was Flo Bones. At the end of the fifth book, she easily disarms a desperate sword-wielding thug with a slime flange.
  • Mirror Scare: The ghost of the witch in The Creeping Shadow can only be seen in reflections, so naturally she does this all the time.
  • Morally Ambiguous Doctorate: Dr. Edmund Bickerstaff, physician, grave-robber and dabbler in dark arts.
  • More Than Mind Control: Bickerstaff's control over Joplin was founded on the latter's insatiable curiosity for knowledge on the Other Side. The same goes for George, to a lesser extent.
  • Murder Is the Best Solution: Casual murder seems to be the Whispering Skull's standard go-to suggestion for any sort of problem.
    Skull: Here's my tip: lure her down to Kitchenware and brain her with a skillet. ... Holly. It's a golden opportunity. There are lots of pointy things there too, if you prefer. But basically a simple smack with a rolling pin would do fine.
  • My Grandson Myself: Turns out Marissa Fittes did a Grand Theft Me on her granddaughter, Penelope, and has been living her life ever since.
  • My Greatest Failure: Lockwood's is the death-by-ghost of his sister Jessica, which he feels he could have prevented if he'd been nearer when the incident happened. This is a major drive in both his hatred for ghosts and his extreme protectiveness towards his team.
  • Mysterious Mist: A side-effect of a ghostly manifestation, described as being white-green in color. It's common enough to warrant the specific term ghost fog.
  • Name Amnesia: In The Empty Grave, Lucy has built rapport with the skull in the jar to such a degree that she tries once again asking him for his name. He claims, however, that it's been so long since he died that he just doesn't remember.
  • Noodle Incident: Whatever happened in Mrs. Barrett's tomb.
  • Obsessed with Food: George, which goes with being a Big Eater.
  • Occult Detective: Whole agencies of them, of which Lockwood & Co. is one.
  • Offing the Offspring: Marissa to both her granddaughter Penelope and presumably her daughter Margaret.
  • Older Than They Look: If the whispering skull's statement at the end of The Creeping Shadow is to be believed, then Penelope Fittes is the same person as her supposed grandmother, Marissa Fittes, but doesn't look a day older than the skull first met her, around forty years before. This turns out to be the result of Marissa taking over the real Penelope's body.
  • Oop North: Lucy's background.
  • Our Ghosts Are Different: They're often called "Visitors" here. Quite a lot of types are present or mentioned and they're categorized as:
    • Type Ones are the usually harmless, if troublesome variety.
    • Type Twos have a purpose of some kind, and can turn violent.
    • Type Threes haven't been officially proven; they can supposedly be communicated with. The ghost in George's ghost jar turns out to be this in the end of the first book, when it starts talking to Lucy. Marissa Fittes, the legendary founder of the Fittes Agency was also said to be able to talk to them. This later turns out to be true and she has one, Ezekiel, as a trusted confidante and companion. In fact, she technically is one, possessing the body of her granddaughter, Penelope Fittes and passing herself off as Penelope.
  • Paranormal Investigation: Massive industries are built around this, from the agencies doing the investigations to the companies providing them the tools to do the investigating.
  • Parental Abandonment: Lucy's mother ships her off to train as a ghost inspector. Implied to be pretty standard, as child labor is ubiquitous in this world.
  • The Pig Pen: Flo Bones, a homeless scavenger who is always covered with river mud and other filth.
  • Poltergeist: One of the Type Two ghosts mentioned in the glossary of the book. A particularly strong one is encountered in the third book.
  • Politically Incorrect Villain: Fairfax naturally assumes Lucy is the weak link of the team, too sensitive to be any kind of threat. Lucy is understandably pissed off.
  • Put Off Their Food: Amusingly subverted at the end of the first book, when Lockwood announces that "a limbless man has been seen shuffling across the bathroom floor on his bloody stumps." Lucy then helps herself to a sausage roll and says that sounds promising. Agents aren't easily upset. On the flip-side, George is put off his cake at the end of the third book when Lucy declares she's quitting Lockwood & Co.
  • Psychic Children: Children and teenagers are the only ones who can clearly detect and deal with ghosts.
  • Psychological Torment Zone: Haunted places; the effects range from a general sense of unease to Heroic B.S.O.D.-inducing terror.
  • Power Trio: Lockwood, Lucy and George.
  • Rain of Blood: The manifestation of one particularly creepy Visitor in Combe Carey Hall. Also the reason why the Red Room is called that.
  • Reasonable Authority Figure: Inspector Barnes, while not very pleasant, is perfectly reasonable. He objects to Lockwood & Co. acting without an adult supervisor, and is definitely justified when they accidentally burn down half of a client's house. Barnes also repeatedly tries to protect Lockwood and Co., warning them off meddling in affairs that might get them killed. At the end of the series, he quickly helps to restore order after Fittes’ downfall and promises to start working at the solving the Problem.
  • Red Herring: A challenge in many ghost investigations is separating fact from fiction when it comes to local folklore surrounding the ghost, since good understanding of a haunting is often the key to vanquishing it. Particularly evident in Combe Carey Hall, where the team both hears a misleading story about a mad nobleman which had nothing to do with the actual source of the haunting and are shown the wrong Screaming Staircase.
    • Also in Aldbury Castle, where the medieval carving of the Creeping Shadow gathering souls turns out to be a complete coincidence.
  • Refusal of the Call: When the ghost in George's ghost-jar starts talking to her, and mentions things like being The Only One for something, Lucy's initial reaction is to seal up the jar again.
  • Rewatch Bonus:
    • Once you learn what happened to Lockwood's sister, you'll see the many hints made towards it throughout the preceeding books.
    • In The Creeping Shadow, Penelope Fittes promises to make Lockwood & Co. "immortal" if they agree to team up with her. This choice of words takes on a new meaning with the ending in mind.
  • The Rival: Quill Kipps, who belongs to the Fittes agency. He knows both George and Lockwood and isn't on very good terms with both of them. Officially put to rest in the fourth book. Kipps resigns from Fittes and by the end of the book it's heavily implied he will be joining Lockwood and Co. at least semi-permanently.
  • Rivals Team Up: Lockwood and Lucy temporarily join forces with Kipps and his team at the end of the second book.
    • Also in the third book, although the rivalry seems to be wearing thin at this point.
  • Screw the Ghosts, We're Partying!: The London elite and agency high-ups constantly arrange fancy parties and society events as a life-affirming way to cope with the Problem. Verges on While Rome Burns.
  • Sealed Evil in a Can: Ghosts can be trapped or preserved when their Sources are locked into silver-glass boxes.
  • Secret Test of Character: When Lucy comes in to be interviewed for Lockwood & Co., the first test she's given is that she's presented with an ordinary object and asked what she can sense from it. After several minutes, she is forced to admit that she can sense nothing and is told that it's just George's toothbrushing cup. At first she tries to leave, thinking she's being made fun of. However, Lockwood explains that many of the previous applicants had made up all sorts of cock-and-bull stories such that if you believed what they said, it was the most haunted cup in Britain.
  • Shapeshifting: There is a powerful variety of Type Two ghosts capable of changing their form, and not necessarily into other humans.
  • Ship Tease:
    • There are plenty of sweet moments between Lucy and Lockwood, with Lucy often going out of her way to describe how good Lockwood looks, how flustered his compliments make her or how naturally inspiring he is. The Skull in particular enjoys teasing her about this. In the final book, it's all but confirmed that Lucy and Lockwood truly love each other.
    • George and Flo Bones get a bit, though it's played for laughs. Not so much in the last book, where things seem to become more serious between them.
  • Shout-Out:
    • The Red Room from the first book is quite probably a shout-out to the H. G. Wells ghost story by the same name.
    • Lockwood and Kipps share last names with other characters with ghost issues: Mr. Lockwood from Wuthering Heights and Arthur Kipps from The Woman in Black.
  • Silk Hiding Steel: Holly Munro might come across as very prim and proper, but she is every bit as competent an agent as anyone else and in battle she can be goddamn terrifying. Do not fuck with Holly Munro.
  • Silver Has Mystic Powers: Like the other series by the same author, The Bartimaeus Trilogy, silver is used in fighting off the supernatural.
  • Skirt Over Leggings: Lucy's usual choice of wear.
  • Slasher Smile: The ghost of Robert Cooke sports an almost permanent one.
  • The Smart Guy: George, of near Insufferable Genius levels.
  • Spot of Tea: Naturally, given the setting. Lockwood & Co. have tea before and even during investigations.
    Lucy: Making tea is a ritual that stops the world from falling in on you.
  • Stringy-Haired Ghost Girl: George declares his hatred for those when the team is at Aldbury Castle. Sure enough, they soon encounter one. Which also has no eyes, for added effect.
  • Sudden Sequel Death Syndrome: Ned Shaw, killed off-page midway through the third book.
  • Sunglasses at Night: Justified. Lockwood sometimes wears sunglasses on cases to shield his eyes from the harsh psychic glow known as other-light.
  • Tagline: "Hauntings are our business..." for the later British printings.
  • Tempting Fate: Lockwood has a habit of this. "It's Probably Nothing" and "What Could Possibly Go Wrong?" are two examples of this.
  • Territorial Smurfette: Lucy does not take kindly to the beautiful Holly Munro joining the company. She eventually eases up a bit on her jealousy and distaste for other women.
  • Throwing Your Sword Always Works
    • Lucy saves Joplin and George from Bickerstaff's ghost by doing this. It turns out that only dumb luck stopped her skewering anyone.
    • Lockwood employs this offensively against one of the attackers at the parade in The Hollow Boy.
  • Token Evil Teammate: The skull in the jar, insofar as it can be considered a teammate.
  • Tomboy and Girly Girl: Lucy and Holly, respectively.
  • Took a Level in Badass: Holly is stated to be much more confident as a field agent by the fourth book, and when Lockwood and Lucy return from the Other Side to find their teammates battling the Rotwell scientists she's a force to be reckoned with. Beware the Nice Ones, indeed.
  • Trademark Favorite Food: Flo’s is liquorice.
  • Treachery Cover-Up: Even after revealing that Fairfax was responsible for Annabel Ward's death, Lockwood & Co are kept from revealing it publicly.
  • True Companions: They may bicker, but the members of Lockwood & Co. are always there for each other.
