Who can you trust when nothing's as it seems?

Welcome to the thrilling and unnervingly prescient world of the slow horses. This team of MI5 agents is united by one common bond: They've screwed up royally and will do anything to redeem themselves. This special tenth-anniversary deluxe edition of a modern classic includes a foreword by the author, discussion questions for book clubs, and an exclusive short story featuring the slow horses. London, England: Slough House is where washed-up MI5 spies go to while away what’s left of their failed careers. The “slow horses,” as they’re called, have all disgraced themselves in some way to get relegated there. Maybe they botched an Op so badly they can’t be trusted anymore. Maybe they got in the way of an ambitious colleague and had the rug yanked out from under them. Maybe they just got too dependent on the bottle—not unusual in this line of work. One thing they have in common, though, is they want to be back in the action. And most of them would do anything to get there─even if it means having to collaborate with one another. When a young man is abducted and his kidnappers threaten to broadcast his beheading live on the Internet, the slow horses see an opportunity to redeem themselves. But is the victim really who he appears to be?

Mick Herron, “the le Carré of the future” (BBC), expands his world of bad spies with an even shadier cast of characters: the politicians, lobbyists, and misinformation agents pulling the levers of government policy. “Confirms Mick Herron as the best spy novelist now working.”—NPR's Fresh Air Now an Apple TV+ series starring Gary Oldman and Kristin Scott Thomas. In London's MI5 headquarters a scandal is brewing that could disgrace the entire intelligence community. The Downing Street superforecaster—a specialist who advises the Prime Minister's office on how policy is likely to be received by the electorate—has disappeared without a trace. Claude Whelan, who was once head of MI5, has been tasked with tracking her down. But the trail leads him straight back to Regent's Park itself, with First Desk Diana Taverner as chief suspect. Has Taverner overplayed her hand at last? Meanwhile, her Russian counterpart, Moscow intelligence's First Desk, has cheekily showed up in London and shaken off his escort. Are the two unfortunate events connected? Over at Slough House, where Jackson Lamb presides over some of MI5's most embittered demoted agents, the slow horses are doing what they do best, and adding a little bit of chaos to an already unstable situation . . . There are bad actors everywhere, and they usually get their comeuppance before the credits roll. But politics is a dirty business, and in a world where lying, cheating and backstabbing are the norm, sometimes the good guys can find themselves outgunned.

If Spook Street is where spies live, Joe Country is where they go to die. In Slough House, the London outpost for disgraced MI5 spies, memories are stirring, all of them bad. Catherine Standish is buying booze again, Louisa Guy is raking over the ashes of lost love, and new recruit Lech Wicinski, whose sins make him an outcast even among the slow horses, is determined to discover who destroyed his career, even if he tears his life apart in the process. Meanwhile, in Regent’s Park, Diana Taverner’s tenure as First Desk is running into difficulties. If she’s going to make the Service fit for purpose, she might have to make deals with a familiar old devil . . . And with winter taking its grip, Jackson Lamb would sooner be left brooding in peace, but even he can’t ignore the dried blood on his carpets. So when the man responsible for killing a slow horse breaks cover at last, Lamb sends the slow horses out to even the score.

"What happens when an old spook starts to lose his mind? Do the Services have a retirement home for people who know too many secrets but don't remember their secrets? Or does someone come to take care of the senile spy for good? These are the questions River Cartwright must ask himself as his grandfather--David Cartwright, a Cold War-era operative--starts to forget to wear pants, and starts believing everyone in his life is someone sent by Services to watch him. However, River has other things to worry about. A bomb goes off in the middle of a flash mob performance in a busy shopping center and kills forty innocent civilians. The agents of Slough House have to figure out who is behind this act of terror before the situation escalates"--

The CWA Gold Dagger Award-winning British espionage novel about disgraced MI5 agents who inadvertently uncover a deadly Cold War-era legacy of sleeper cells and mythic super spies. The disgruntled agents of Slough House, the MI5 branch where washed-up spies are sent to finish their failed careers on desk duty, are called into action to protect a visiting Russian oligarch whom MI5 hopes to recruit to British intelligence. While two agents are dispatched on that babysitting job, though, an old Cold War-era spy named Dickie Bow is found dead, ostensibly of a heart attack, on a bus outside of Oxford, far from his usual haunts. But the head of Slough House, the irascible Jackson Lamb, is convinced Dickie Bow was murdered. As the agents dig into their fallen comrade's circumstances, they uncover a shadowy tangle of ancient Cold War secrets that seem to lead back to a man named Alexander Popov, who is either a Soviet bogeyman or the most dangerous man in the world. How many more people will have to die to keep those secrets buried?

In his best and most ambitious novel yet, Mick Herron, “the le Carré of the future” (BBC), offers an unsparing look at the corrupt web of media, global finance, spycraft, and politics that power our modern world. “This is a darker, scarier Herron. The gags are still there but the satire's more biting. The privatization of a secret service op and the manipulation of news is relevant and horribly credible.”—Ann Cleeves, author of the Vera Stanhope series At Slough House—MI5’s London depository for demoted spies—Brexit has taken a toll. The “slow horses” have been pushed further into the cold, Slough House has been erased from official records, and its members are dying in unusual circumstances, at an unusual clip. No wonder Jackson Lamb's crew is feeling paranoid. But are they actually targets? With a new populist movement taking hold of London's streets and the old order ensuring that everything's for sale to the highest bidder, the world's a dangerous place for those deemed surplus. Jackson Lamb and the slow horses are in a fight for their lives as they navigate dizzying layers of lies, power, and death.
