“A bizarre yet effective yoking of the spy and horror genres.” ―The Washington Post Book World

The Lovecraftian Singularity has descended upon the world in
The Labyrinth Index, beginning an exciting new story arc in Charles Stross' Hugo Award-winning Laundry Files series!

Since she was promoted to the head of the Lords Select Committee on Sanguinary Affairs, every workday for Mhari Murphy has been a nightmare. It doesn’t help that her boss, the new Prime Minister of Britain, is a manipulative and deceptive pain in the butt. But what else can she expect when working under the thumb of none other than the elder god N’yar Lat-Hotep a.k.a the Creeping Chaos?

Mhari's most recent assignment takes her and a ragtag team of former Laundry agents across the pond into the depths of North America. The United States president has gone missing. Not that Americans are alarmed. For some mysterious reason, most of the country has forgotten the executive branch even exists. Perhaps it has to do with the Nazgûl currently occupying the government and attempting to summon Cthulhu.

It's now up to Mhari and her team to race against the Nazgûl's vampire-manned dragnet to find and, for his own protection, kidnap the president.

Who knew an egomaniacal, malevolent deity would have a soft spot for international relations?

Review

“Stross still spins a heck of a yarn.” ―Kirkus Reviews on The Delirium Brief

"Gaudy and gory....This is Stross in one of his darker moods....The political side of the book...signals some of the real-world anxieties that stand behind the entire series." ―
Locus on The Delirium Brief

“A fast-paced blend of espionage thrills, mundane office comedy and Lovecraftian horror.” ―SFX on
The Rhesus Chart

“Alternately chilling and hilarious.” ―
Publishers Weekly on The Jennifer Morgue

“Combines a le Carré-style espionage thriller with Lovecraftian horror to great effect.” ―
The Guardian on The Fuller Memorandum

“Smart, literate, funny.”―Lev Grossman, author of The Magicians

“A bizarre yet effective yoking of the spy and horror genres.”―
The Washington Post Book World

“Imagine a world where gnarly Lovecraftian demons are all too real yet are routinely neutralized with high-tech wizardry by a supersecret British spy agency, and you'll get an inkling of the genre-bending territory Stross explores in his Laundry Files novels.” ―
Booklist on The Fuller Memorandum

Top reviews from the United States

  • Reviewed in the United States on November 4, 2018
    As the Laundry Files series moves further into CASE NIGHTMARE GREEN, I keep wondering how Stross is going to pull off another adventure without its being a total downer, and I keep being pleasantly surprised. "Labyrinth Index" takes place six months after the last installment, "Delirium Brief," and it's a solid entry.

    Mhari Murphy, now the Baroness Karnstein (I had to look that reference up to get the joke) is chosen by the new Prime Minister to lead a team to rescue the American President, who seems to have disappeared. More worrisome still, almost everyone in America has forgotten that the executive branch of government even exists.

    The plot is roughly inspired by "The Dirty Dozen." The Prime Minister, Fabian Everyman, is the human avatar of the Black Pharaoh and is just as charming and deadly as ever. He selects Mhari's team for her and the implication is clear that he isn't certain of their loyalty. It's also clear from the start that the members of the team won't all make it back, at least not all in one piece. We get to see new aspects of characters we already know, particularly Mhari: I found it easier to empathize with her than I had anticipated. She's grappling with the implications of her vampirism, as well as a new life peerage and an unsatisfactory relationship, all of which is saddling her with a case of imposter syndrome.

    The scenes set in the US are both a sendup and affirmation of conspiracy theorists and had me nervously looking over my shoulders; the scenes with the dark god who is leading the American coup are creepy as hell; and the climax is both horrific and hilarious in a way that only Stross could pull off.

    One additional comment: Given the author's opinions of Brexit and the US political climate (hint: he's not a fan) I was halfway expecting a bitter polemic, but fortunately that isn't the case. Stross is too good a writer to let that happen. Instead we get a ripsnorting adventure with political undertones, which work well to deepen the story, and a semi-happy ending for Mhari and her swain. Definitely recommended, but as others have commented, it's best to start at the beginning of the series as you'll get so much more out of it.

  • Reviewed in the United States on July 8, 2020
    The Laundry Files is one of the better fantasy series around. It’s an oddball, often hilarious, other times tense-action hybrid, composed of equal parts spy-action novel, old style horror tale, and Dilbert-like observations oh working in a government, later privatized bureaucracy. The earliest novel takes a bow to Len Deighton’s spy characters, a later one more explicitly to Ian Fleming’s James Bond. There’s more science alluded to in Stross’s tales (mostly mathematical and dealing with multiple universes with cross-dimensional gateways, and binding, releasing, protecting and attacking magic spells (geases, wards…) conceived of as mathematical computations rather than old style spell casting) The Laundry is a very old British secret agency (established during Elizabeth I’s time by spy master Francis Walsingham and mage John Dee) whose charge is to protect the country from alien incursions. And the aliens, often specifically, have the names and gruesome characteristics of H. P. Lovecraft’s heated imaginations –the Old Ones, the Eater of Souls, Cthulhu, a civilization of fish-like beings below the seas.

    It’s the job of Bob, a computer mathematician, to deal with these monsters. He’s no James Bond but he muddles through. Much of the time, he’s as plagued by all the paperwork and administrivial duties assigned him by his overlings –HR is a particular nemesis—as by having to improvise sways to ward off or destroy mind and universe destroying Evil (or Morally Indifferent) Creatures from Abroad. Bob narrates the first novels. His wife Mo, a mage-mathematician who carries with her a soul-eating white violin made completely from the bones of the tortured souls killed in Nazi death camp, takes over for one later on, and two vampires, Mahri Murphy and another one whose name eludes me as I write, narrate other volumes. Bob’s boss is an ossified and utterly terrifying Old English Don type named Angleton, who is really a bound monster who has been bound for so long that he assumes semi-human character traits and loyalties. When Angleton is killed in a Big Boom battle with an ancient vampire who has infiltrated the agency, Bob assumes his boss’s mantle, and along with it, inside Bob now lodges the never completely silent persona and powers of the Eater of Souls. (Bob sleepwalks occasionally, and since when he does, there’s no guarantee that Bob will rule his mind and body and not the unbridled Eater, Mo has to leave the house for fear of having her soul noshed by her still-loving but now possessed husband.)

    The novels are jargon-heavy but largely to make fun of it. Stross really has fun with the techno-geek language and behaviors of his characters. he action is fast and furious. The form of the storytelling is roughly the same across nine novels: there’s a middle-sized occult crisis at the beginning of the novel, at least one or two minor but nerve-wracking encounter en route through the narrative, and a wham bang ten-seconds-left-to-save-the-world ending. The stakes climb higher from novel to novel. If we were talking an occult Doomsday Clock, it’d be ten seconds past midnight, not before, by the time we reach The Labyrinth Index (2018). On a scoreboard, Scary Monsters against Us, SM has a hefty lead over US.

    This book is fascinating to re-read in 2025 as an American reader. I have to wonder if it was written now if Mr. Stross would have made Trump and Musk Cthulhuian mythos monsters by the amount of selfish collateral damage they have caused in such a short time. I can't deny it's been something I've contemplated a lot recently. Maybe not: cosmic space monsters seem to have an alarming amount of intellect which both lack. Great series.
  • Reviewed in the United States on November 3, 2018
    I'm not a big fan of Mhari at all, but this book really does her justice. This book is all about her, and much of it is told in the first person point of view, and despite not liking Mhari, this is a really good entry in the series. Not quite as good as The Delirium Brief, but that was a 6.5 star book, in my opinion. This one is solid 5 star.

    In addition to Mhari's tale, it advances the plot wrt the USA, it also gives hints at a possible solution to Nyar'lo thotep taking over the UK. The possible solution being part of continuity ops, but as I said, just a hint.

    Overall, well worth it, and a worth addition to the series. No Bob, and no Cassie, but at least Jonquil/Yarisol evoked Cassie pretty well...

    Brains: How much coffee did you drink?
    J/Y: all of it?!
    Brains: How many times did you refill it?
    J/Y: 3?! It kep running out!!

    Side note: whenever I picture Mhari, I see Mindy Kaling, and since their descriptions aren't even close, I'm not sure why.

    Estimated Charles Stross: How could you do that? This is a one-shot story and is thrilling, amazing, awesome. There is a lot of action and magic involved. The main story is agile and smart. But Damm it! I need more. You Know? I need to know what does Fabian wants.

    5.0 out of 5 stars A new point of view
    Reviewed in Germany on November 14, 2018
    Following The Annihilation Score and The Nightmare Stacks Charles Stross offers yet another view point from the Laundry. Given Mhari's history it might seem a strange choice, but not only does this make a little reparation for all the "crazy" comments (I'm looking at you Bob) it gives a much more human insight into the New Management.

    Stross plays with elements of the previous books in the series extremely well, giving more depth to the universe.

    As much as I don't want it to end I can hardly wait to see how it does!

    I was always a fan of the Cthulhu world and when I was in Highschool I read all of the Lovecraft books. So it was with a bit of glee when I discovered the Laundry Files and greatly enjoy the way Steiß plays in this sandbox.

    We get a bit of a “perspective shift” in this book, but it works and is just as entertaining as the previous books.

    5.0 out of 5 stars Outstanding addition to the Laundry universe
    Reviewed in Australia on December 2, 2018
    The series is evolving; some of my favorite characters have moved on, lesser characters from previous stories come to the fore. As usual, anyone with a knowledge of bureaucracy (either side of the Atlantic) will recognize situations and archetypes, but I especially enjoy the way Strauss uses the "black helicopter" and "stiff upper lip" stereotypes of the differing government organisations he is satirizing. The only real question is whether it's satire or fact :)

    5.0 out of 5 stars The Laundry Files kicks into high gear!
    Reviewed in Canada on November 5, 2018
    Fantastic entry in the series, definitely stronger than some of the other books, although one still burdened by some rather ham-fisted expositions and jarring changes in perspectives. On the other hand it's still really entertaining and scary and Stross brings out his while arsenal in this one, calling back to some of his earlier works (especially his novella "A Colder War") to deliver a truly apocalyptic and game changing plot.
