The terrorist Guy Fowle has escaped from prison. Jude Lyon of MI-6 has been saved from a Syrian ambush by his lover - and enemy? - Julia Ermolaeva. A mysterious Russian has been murdered in London and his thumb cut off. The chancellor of the Exchequer has made an unfortunate social connection at a party, which he hopes he can keep secret. And suddenly, the world is literally going up in flames. Jude needs to start putting together the pieces of this jigsaw and quickly, because someone is putting into play a terrifying Russian plan to disable and destroy the UK. 

A Russian defector is found brutally murdered in a London hotel. Only four people knew he had turned - the four most important and powerful figures in Whitehall. There's only one conclusion - a mole has infiltrated the highest levels of the nation's security. Operating in secret from within Westminster's darkest corners, former spy Solomon Vine must uncover the traitor. Because Britain's future hangs in the balance. And with it the fate of the whole world.

Slough House is Jackson Lamb’s kingdom; a dumping ground for members of the intelligence service who’ve screwed up: left a secret file on a train, blown surveillance, or become drunkenly unreliable. They’re the service’s poor relations – the slow horses – and bitterest among them is River Cartwright, whose days are spent transcribing mobile phone conversations.

They killed Robert Harland today, and they're going to kill the rest of you. This is the warning private investigator Paul Samson receives right after Joni Fremantle, the woman he has been guarding for a mysterious client, gives him the slip. No time to worry about that now: his life, and those of Denis Hisami, Anastasia Christakos and even the young Syrian Naji, is on the line. Samson is sure he knows why - to expose a company supplying funds to far-right groups across Europe is to paint a target on your own back.

Berlin. 1963. The height of the Cold War and an early morning spy swap. On one side of the trade: Martin Keller, an American physicist who once made headlines, but who then disappeared into the English prison system. Keller's most critical possession: his American passport. Keller's most ardent desire: to see his ex-wife, Sabine, and their young son. But Martin has questions: who asked for him? Who negotiated the deal? Just the KGB bringing home one of its agents? Or, as he hopes, a more personal intervention? 

When disgraced spy Solomon Vine's friend and rival Gabriel Wilde vanishes without trace, it's only Vine who might be able to discover what has happened to him. A single missing file holds the key. That, too, is gone. But its contents, Vine is told, are incendiary. There were few Wilde could trust. And being one of them appears to have fatal consequences. But as Vine's off-the-books investigation begins to reveal the shocking truth, he realizes there's much more at stake than one man's life.

1993: student Lachlan Kite is sent to post-Soviet Russia in the guise of a language teacher. In reality, he is there as a spy. Top secret intelligence agency BOX 88 has ordered Kite to extract a chemical weapons scientist before his groundbreaking research falls into the wrong hands. But Kite’s mission soon goes wrong and he is left stranded in a hostile city with a former KGB officer on his trail.

On a deserted road in Calabria, Greek aid worker Anastasia Cristakos is driving alone to visit one of the new refugee centres funded by billionaire Denis Hisami, whom she has recently married. She slows down to greet two African migrants she recognises. Too late she realises they are not her friends. This is an ambush. She manages a desperate phone call to Hisami before her Mafia kidnappers silence her with a powerful drug. Hours later she wakes up in the pitch dark on a container ship powering eastwards across the Mediterranean.

In the office at MI5 where he works, they call Jonas Merrick 'the eternal flame'. It isn't a compliment. It's because he never goes out. He never goes undercover, never does surveillance, never goes with the teams that kick down the doors or seize the suspects off the street. He commutes into work and sits at his desk and then he goes home. But Jonas has qualities the hot-shots fail to notice: a steely concentration, a ruthless ability to focus and find the enemy hiding in plain sight.

Three friends from a mission many years ago reconnect when one of them dies in mysterious circumstances on remote Ascension Island. Rory Bannatyne had been tasked with tapping a new transatlantic data cable, but a day before he was due to return home, he is found hanged. When Kathryn Taylor, on the South Atlantic MI5 desk, begs ex-spy Elliot Kane to go over and investigate, he can't say no, but it's an uneasy reintroduction to the intelligence game.

Jeremy Summers, a British banker with a secret that could reveal MI6 intelligence sources involved in the war against drug-funded terrorism, has been seized at gunpoint, in broad daylight, on the streets of west London. An old contact, Raglan - an Englishman who served in the French Foreign Legion - is on his trail. Raglan's pursuit will lead him to the winter-ravaged wasteland of a remote Russian penal colony. A place that holds Russia's most brutal murderers. A place of death and retribution. How will he get in? More importantly, how will he get out...alive?

Ryan Wilkins grew up on a trailer park, a member of what many people would call the criminal classes. As a young Detective Inspector, he's lost none of his disgust with privileged elites - or his objectionable manners. But he notices things; they stick to his eyes. His professional partner, DI Ray Wilkins, of affluent Nigerian London heritage, is an impeccably groomed, smooth-talking graduate of Balliol College, Oxford. You wouldn't think they would get on. They don't. But when a young woman is found strangled at Barnabas Hall, they're forced to. 

Someone is setting fire to Sheffield. It starts with small things – dustbins and abandoned sheds – so people don’t notice at first. But the calling card is there if you look for it. Soon the fires spread to offices, homes, people. The Firewatcher’s followers are growing and they have one particular blaze in mind – one that the police would do well to pay attention to. But D/S Adam Tyler is distracted by a case, one that he is unknowingly connected to. And if he can’t discover the link between the fires and himself, he will burn – along with the entire city. 

In 2005, Marin Katich, living in Croatia under an alias, is being watched. Before the year is out, he has been assaulted, arrested, charged with serious war crimes and locked up in Scheveningen Prison in The Hague, waiting for his case to come before the International War Crimes Tribunal for the former Yugoslavia. In Sydney, Anna Rosen, a freelance journalist, is sent photos on her computer of a man she knows to be dead - gunned down in a brutal ambush in Bosnia over a decade ago. A man she'd once loved but who had betrayed her. Is it possible the photos really are of Marin Katich?
