Slough House

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?

This is Jackson Lamb's kingdom: a dumping ground for spies who've screwed up. Once high fliers, they're now slow horses, condemned to a life of pushing paper as punishment for crimes of drugs and drunkenness, lechery and failure, politics and betrayal. In drab and mildewed offices, these highly trained spies moan and squabble, stare at the walls, and dream of better days - not one of them joined the Intelligence Service to be a slow horse, and the one thing they have in common is their desire to be back in the action.

From the Intelligence Service purgatory that is Slough House, where disgraced spies are sent to see out the dregs of their careers, Jackson Lamb is on his way to Oxford, where a former spook has turned up dead on a bus. Dickie Bow was a talented streetwalker once, good at following people and bringing home their secrets. He was in Berlin with Lamb, back in the day. But he's not an obvious target for assassination in the here and now.

Dieter Hess, an aged spy, is dead, and John Bachelor, his MI5 handler, is in deep, deep trouble. Death has revealed that the 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.

Slough House is the Intelligence Service outpost for failed spies, former high-fliers now dubbed the 'slow horses'. Catherine Standish, one of their number, worked in Regent's Park long enough to understand treachery, double-dealing and stabbing in the back, and she's known Jackson Lamb long enough to have learned that old sins cast long shadows. And she also knows that chance encounters never happen to spooks, even recovering drunks whose careers have crashed and burned.

The 'Old Bastard' raised his grandson to be a hero, not a slow horse. Now, far from joining the myths and legends of Spook Street, River Cartwright is part of Jackson Lamb's team of pen-pushing no-hopers at Slough House. Which doesn't mean he won't ditch everything and go rogue when his grandfather comes under threat. Lamb worked with Cartwright back in the day, and knows better than most that this is no innocent old man.

London rules might not be written down, but everyone knows rule one. Cover your arse. Regent's Park's First Desk, Claude Whelan, is learning this the hard way. Tasked with protecting a beleaguered prime minister, he's facing attack from all directions himself: from the showboating MP who orchestrated the Brexit vote and now has his sights set on Number 10; 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.

Old spooks carry the memory of tradecraft in their bones, and when Solomon Dortmund sees an envelope being passed from one pair of hands to another in a Marylebone café, he knows he's witnessed more than an innocent encounter. But in relaying his suspicions to John Bachelor, who babysits retired spies like Solly, he sets in train events which will alter lives.

In Slough House 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 outcast even among the slow horses, is determined to discover who destroyed his career, even if he tears his life apart in the process.

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.

A year after a calamitous blunder by the Russian secret service left a British citizen dead from novichok poisoning, Diana Taverner is on the warpath. What seems a gutless response from the government has pushed the Service's First Desk into mounting her own counter-offensive—but she's had to make a deal with the devil first. And given that the devil in question is arch-manipulator Peter Judd, she could be about to lose control of everything she's fought for.

In MI5 a scandal is brewing and there are bad actors everywhere. A key member of a Downing Street think-tank has disappeared without a trace. Claude Whelan, one-time First Desk of MI5's Regent's Park, is tasked with tracking her down. But the trail leads straight back to Regent's Park HQ itself, with its chief, Diana Taverner, as prime suspect. Meanwhile her Russian counterpart has unexpectedly shown up in London but has slipped under MI5's radar.

Old spies grow ridiculous, River. Old spies aren't much better than clowns. Or so David Cartwright used to say, but he forgot to add they can be dangerous too, especially if they've fallen on hard times - as Diana Taverner learns when the past lands on her desk. 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 the would-be blackmailer is soon being used as Taverner's solution to a much newer problem.
