London's Slough House is where the 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 here. Maybe they messed up an op badly and 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 all have in common, though, is they all 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.
Now the slow horses have a chance at redemption. An old Cold War-era spy is found dead on a bus outside Oxford, far from his usual haunts. The despicable, 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?

Dieter Hess, an aged spy, is dead, and John Bachelor, his MI5 handler, is in deep, deep trouble. Death has revealed that deceased had been keeping a secret second bank account—and there’s only ever one reason a spy has a secret second bank account. The question of whether he was a double agent must be resolved, and its answer may undo an entire career’s worth of spy secrets.

When one of their own is kidnapped, the washed-up MI5 operatives of Slough House--the Slow Horses, as they're known--outwit rogue agents at the very highest levels of British Intelligence, and even to Downing Street itself.

London: Slough House is the MI5 branch where disgraced operatives are reassigned after they've messed up too badly to be trusted with real intelligence work. The "Slow Horses," as the failed spies of Slough House are called, are doomed to spend the rest of their careers pushing paper, but they all want back in on the action.

When one of their own is kidnapped and held for ransom, the agents of Slough House must defeat the odds, overturning all expectations of their competence, to breach the top-notch security of MI5's intelligence headquarters, Regent's Park, and steal valuable intel in exchange for their comrade's safety. The kidnapping is only the tip of the iceberg, however--the agents uncover a larger web of intrigue that involves not only a group of private mercenaries but the highest authorities in the Secret Service. After years spent as the lowest on the totem pole, the Slow Horses suddenly find themselves caught in the midst of a conspiracy that threatens not only the future of Slough House, but of MI5 itself.

What happens when an old spook loses his mind? Does the Service have a retirement home for those who know too many secrets but don’t remember they’re secret? Or does someone take care of the senile spy for good?

These are the paranoid concerns of David Cartwright, a Cold War–era operative and one-time head of MI5 who is sliding into dementia, and questions his grandson, River, must figure out answers to now that the spy who raised him has started to forget to wear pants. But River, himself an agent at Slough House, MI5’s outpost for disgraced spies, has other things to worry about. A bomb has detonated in the middle of a busy shopping center and killed forty innocent civilians. The “slow horses” of Slough House must figure out who is behind this act of terror before the situation escalates.

At Regent's Park, the Intelligence Service HQ, its new chief Claude Whelan is learning the job the hard way.

Tasked with protecting a beleaguered Prime Minister, he's facing attack from all directions: from the showboating MP who orchestrated the Brexit vote, and now has his sights set on Number Ten; from the showboat's wife, a tabloid columnist, who's crucifying Whelan in print; and especially from his own deputy, Lady Di Taverner, who's alert for Claude's every stumble. Meanwhile, the country's being rocked by an apparently random string of terror attacks.

Over at Slough House, the last stop for washed up spies, the crew are struggling with personal problems: repressed grief, various addictions, retail paralysis, and the nagging suspicion that their newest colleague is a psychopath. But collectively, they're about to rediscover their greatest strength - making a bad situation much, much worse.

British spy master Mick Herron returns with an explosive novella set in the same world as his multiple CWA Dagger–winning Slough House series

John Bachelor is the saddest kind of spy: not a joe in the field, not even a desk jockey, but a milkman—a part-time pension administrator whose main job is to check in on aging retired spies. Late in his career and having lost his wife, his house, and his savings after a series of unlucky choices, John's been living in a dead man's London apartment, hoping the bureaucracy isn't going to catch up with him and leave him homeless. But keeping a secret among spies is a fool's errand, and now John has made himself eminently blackmailable.

'A slim serio-comic offering . . . It plays out typically cleverly' Sunday Times

If life in the Intelligence Service has taught John Bachelor anything, it's to keep his head down. Especially now, when he's living rent-free in a dead spook's flat.

So he's not delighted to be woken at dawn by a pair of Regent's Park's heavies, looking for a client he's not seen in years. John doesn't know what secrets Benny Manors has stolen, but they're attracting the wrong attention. And if he's to save his own skin, not to mention safeguard his living arrangements, John has to find Benny before those secrets see the light.

Benny could be anywhere, provided it serves alcohol. So John sets out on a reluctant trawl through the bars of the capital, all the while plagued by the age-old questions: Will he end up sleeping in his car? How many bottles of gin can he afford at London prices?

And just how far will Regent's Park go to prevent anyone rocking the Establishment's boat?

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.

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.

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.

*A Slough House Christmas short story from the Sunday Times number one bestseller of BAD ACTORS.*

Here in Slough House, the intelligence service's home for inept spies, it's beginning to feel a lot like Christmas.

Roddy Ho is used to being the one the slow horses turn to when they need miracles performed, and he's always been Jackson Lamb's Number Two. So when Lamb has a photograph that needs doctoring, it's Ho he entrusts with the task. Christmas is a time for memories, but Lamb doesn't do memories - or so he says. But what is it about the photo that makes him want to alter it? How would the slow horses cope if Roddy Ho didn't exist? And most importantly of all, are the team having Christmas drinks, and if so, where?

Standing by the Wall offers a glimpse into the kind of seasonal merriment you might expect at Slough House, where the boss generally marks the festive season with an increase in hostilities. But then, this is the secret service, not Secret Santa. And the slow horses aren't here to enjoy themselves.

In this standalone spy thriller, Mick Herron, creator of Slough House, introduced Tom Bettany, a man with a violent past and only one thing to live for: Avenging his son's death.

Tom Bettany is working at a meat processing plant in France when he gets a voicemail from an Englishwoman he doesn’t know telling him that his estranged 26-year-old son is dead—Liam Bettany fell from his London balcony, where he was smoking pot.

Now for the first time since he cut all ties years ago, Bettany returns home to London to find out the truth about his son’s death. Maybe it’s the guilt he feels about losing touch with Liam that’s gnawing at him, or maybe he’s actually put his finger on a labyrinthine plot, but either way he’ll get to the bottom of the tragedy, no matter whose feathers he has to ruffle. But more than a few people are interested to hear Bettany is back in town, from incarcerated mob bosses to those in the highest echelons of MI5. He might have thought he’d left it all behind when he first skipped town, but nobody ever really walks away.

THE NINTH BOOK IN THE SERIES BEHIND SLOW HORSES, AN APPLE ORIGINAL SERIES NOW STREAMING ON APPLE TV+

Jackson Lamb and the bad spies of Slough House are caught in a deadly battle between MI5’s secret past and its murky future in this gripping, hilarious, and heartbreaking thriller by Mick Herron, “the le Carré of the future” (BBC).

“Old spies grow ridiculous, River. Old spies aren’t much better than clowns.” Or so David Cartwright, the late retired head of MI5, used to tell his grandson. He forgot to add that old spies can be dangerous, too, especially if they’ve fallen on hard times—as River Cartwright is about to learn the hard way.

David Cartwright, long buried, has left his library to the Spooks’ College in Oxford, and now one of the books is missing. Or perhaps it never existed. River, once a “slow horse” of Slough House, MI5’s outpost for demoted and disgraced spies, has some time to kill while awaiting medical clearance to return to work, and starts investigating the secrets of his grandfather’s library.

Over at the Park, MI5 First Desk Diana Taverner is in a pickle. An operation carried out during the height of the Troubles laid bare the ugly side of state security, and those involved are threatening to expose details. But every threat hides an opportunity, and Taverner has come up with a scheme. All she needs is the right dupe to get caught holding the bag.

Jackson Lamb, the enigmatic and odiferous head of Slough House, has no plans to send in the clowns. On the other hand, if the clowns ignore his instructions, any harm that befalls them is hardly his fault. But they’re his clowns. And if they don’t all make it home, there’ll be a reckoning.
