Slow Horses is an espionage novel by British writer Mick Herron, published in 2010. It is the first novel in the Slough House series, following River Cartwright and a group of disgraced MI5 agents as they attempt to escape their desk jobs.

Plot

Slough House is an MI5 office overseen by Jackson Lamb, a crotchety Cold War era agent, where "Slow Horses" (disgraced agents) are relegated to pushing paper and sorting through bins.

Everyone has a reason for being at Slough House. River Cartwright accidentally shut down London King's Cross railway station during a training assessment, a mistake he claimed resulted from being fed false information. Louisa Guy misplaced an arms dealer, Min Harper left confidential information on a train and Roddy Ho for his repulsive personality. Only Sidonie "Sid" Baker, a new agent at Slough House has unknown origins. Baker starts to be given assignments in the field and quickly attracts the envy of other agents. After Baker is tasked with following a disgraced conservative journalist, Robert Hobden, Cartwright does everything he can to get involved.

When Hassan Ahmed, a British-Pakistani university student university student, is kidnapped and held hostage by the white nationalist group Sons of Albion, the agents of Slough House begin to wonder what they can do to help. The Kidnappers announce they will behead Ahmed on a live stream in 36 hours, rain, hail or shine. What the agents of Slough House don't know is that the terrorists have been infiltrated by a former Slow Horse, Alan Black, who has been secretly tasked by the deputy director of MI5, Diana Taverner, to sabotage the Kidnappers as a publicity stunt for the agency.

Hobden suspects foul play, as he previously overheard Taverner in a bar discussing creating sting operations on far-right political groups. When Hobden begins to make attempts to expose the scheme publically, Taverner convinces Jed Moody, a discontent Slough House agent with a background in international espionage, to plan an assassination attempt on Hobden. Unbeknownst to Moody, Cartwright and Baker are monitoring Hobden's house the night he attempts a masked break-in. Before noticing the intruder, Baker reveals to Cartwright she was assigned to Slough House to survey him. The pair rush to Hobden's defence. A violent scuffle results in Moody accidentally shooting Baker. Hobden and Moody flee into the night, while River rushes Baker to the hospital.

Realising what he's done, Moody returns to Slough House for supplies in preparation to go on the run. Both Louisa Guy and Min Harper return to work after hours for some private time together and rush to attack the masked intruder. The embroiled Moody and Harper fall down the office stairs, where Moody dies instantly after breaking his neck on impact. After Jackson Lamb is alerted to the death of two of his in one night, he begins to piece together Taverner's meddling in his affairs.

Hobden rushes to the house of Peter Judd, a conservative politician. While Judd is reluctant to help Hobden expose MI5's anticks, Hobden threatens to release a compromising photo of a young Judd throwing a Nazi salute.

Meanwhile, the kidnappers have discovered and killed the traitor within their ranks. After they change their plans and take their hostage on the road, Taverner begins to look to hide her involvement. Taverner begins to alert people within MI5 that one of the kidnappers was a former Slow Horse and tries to pin the situation on Jackson Lamb. Lamb decides to break into the MI5 headquarters with Cartwright to find evidence and confront Taverner with proof she is framing the agents of Slough House.

The other Slow Horses work to track down the van the kidnappers had hired. Working through the known aliases of the former slough house agent who infiltrated the group, the Slow Horses find the booking. Roddy Ho works out how to hack the rental company's navigation system and they alert the police of the forest where the kidnappers have stopped. The two remaining kidnappers in the meantime had begun to argue, disagreeing about actually killing Hasan. Hasan uses the opportunity to escape and hide in the forest before he is saved by the police.

In the days after, it is announced that Robert Hobden died in a hit-and-run accident and Cartwright discovers all records of Sid Baker have been wiped from existence, her status now unknown.

Publication History

Constable first published Slow Horses in the United Kingdom in 2010. The book was published by Soho Press in the United States.

The initial release of the novel was unsuccessful and Constable decided not to publish any further books in the series. In 2015, John Murray acquired the rights to release the novel in the UK and released a new edition. The book began to find mainstream success after Waterstones named the novel its ‘thriller of the month’ in August 2017.

In 2017, Nancy Pearl included Slow Horses on a list of books she recommended on NPR. Pearl described the book as "great fun" and said "Unlike some series of thrillers or mysteries, it gets better, each book is better than the one before." In response, Soho printed an additional 2,000 copies of the book which sold out in 24 hours; they would go on to sell 20,000 copies that month.

Background

Herron began the book in 2008. Prior to writing Slow Horses, Herron primarily wrote detective fiction whilst he was working in the legal department of an employment-issues research firm.

In 2005, Herron was commuting to work when the London Subway Bombings struck. The experience inspired Herron to shift from writing detective to spy fiction. While he had did not feel qualified to write about world events, the bombings made him realise that “to be on the front line, you just have to be in a city. Suddenly, everywhere seems to be a viable target. So that opened the door and allowed me to write about such things.” Herron references the morning during a scene where River Cartwright reflects:

People talked about that day in different ways. Either it was a story about them in which bombs happened, or it was a story about the bombs, and they’d just happened to be there.

While Herron did not have any previous experience or knowledge of working in the intelligence community, he cites Len Deighton and John le Carré as influences.

Reception

Writing for The Booklist, Thomas Gaughan said Herron's novel was "filled with acidic wit and engaging misdirection... with enough suspense, double-dealing, and mayhem for thriller devotees; but it's also a wonderfully funny, farcical, deeply cynical skewering of politics, bureaucrats, turf wars, and the Great Game."

Jeff Quest, creator of spy fiction review website Spy Write, praised Herron's cast of characters, saying while they might not be likeable on the surface, "you understand and relate to their motivations and foible." Quest also noted Herron's "ability to capture the truth of city living" and complimented his use of real world locations throughout the story.

The book was listed by Jake Kerridge in The Telegraph as one of "The 20 best spy novels of all time."

The book was shortlisted for the 2010 CWA Ian Fleming Steel Dagger for best thriller of the year.

On the social cataloging website Goodreads, Slow Horses holds an average rating of 4.01/5 stars from 54,500 reviews.
