When pirates attack a cargo ship off the Somalian coast and one of them is found to be a British-born Pakistani, MI5 Intelligence Officer Liz Carlyle is brought in to establish how and why a young British Muslim could go missing from his family in Birmingham and end up on board a pirate skiff in the Indian Ocean, armed with a Kalashnikov. After an undercover operative connected to the case turns up dead in a shipping office in Athens it looks like piracy may be the least of the Service’s problems...

When a Russian intelligence officer approaches MI5 with vital information about the imminent cyber-sabotage of an Anglo-American Defence programme, he refuses to talk to anyone but Liz Carlyle. But who is he, and what is his connection to the British agent? At a tracking station in Nevada, US Navy officers watch in horror as one of their unmanned drones plummets out of the sky. Is this a Russian plot to disable the West’s defences? Or is the threat coming from elsewhere?

In 2012, in a Middle Eastern souk, CIA agent Miles Brookhaven was attacked. He was infiltrating rebel groups in the area and no one was certain if his cover had been blown or if the act was just an arbitrary attack. Now, Liz Carlyle and her Counter Terrorism unit in MI5 have been charged with the task of watching the international under-the-counter arms trade and British Intelligence forces have become increasingly concerned that extremist Al-Qaeda jihadis are building their power base ready to launch another attack.

Following a gruelling operation in Paris, Liz Carlyle’s bosses post her to MI5’s counter-espionage desk, but they haven’t counted on the fallout from Putin’s incursions into the Ukraine. Liz needs to track down a Russian spy who has entered the UK before he completes his fatal mission. Meanwhile, the intelligence services are in the spotlight. In response to the debate raging around privacy and security, they hire Jasminder Kapoor, a controversial civil rights lawyer, to explain the issues to the public.

MI5 Intelligence Officer Liz Carlyle learns from one of her agents that suspicious meetings have been taking place at an Islamic bookshop. She feels instinctively that a terrorist cell is at work and when she reports this to Charles Wetherby, the Director of Counter Terrorism, a surveillance operation is immediately put into place. An attack seems imminent.

A man lies dying in a hospital in upstate Vermont. The nurses know only that he is an academic at a nearby university, but they have been instructed to call the FBI should anyone visit their patient. News of this suspected Russian illegal soon reaches MI5, where Liz Carlyle has been contacted by Mischa, a top secret source who is requesting a clandestine rendezvous in Berlin. 

To those who don’t really know her, Kate Henderson’s life must seem perfectly ordinary. But she is in fact a senior MI6 officer, who right now is nursing the political equivalent of a nuclear bomb. Kate’s most recent mission has yielded the startling intelligence that the British Prime Minister has cancer - and that one of the leading candidates to replace him may be a Russian agent of influence. Up against the clock to uncover the Russian mole, Kate risks everything to get to the truth.

The intelligence service puts two years and over £100k into the training of new field officers. You're shown how to steal cars, strip weapons, hack bank accounts. There are courses on the use of blackmail and improvised explosives, two workshops solely dedicated to navigating by the stars. But nothing about what I had heard one old spy call whiplash. No one tells you how to go home.

Six weeks before she is due to take up her position as the first female head of MI6, Amelia Levene vanishes without a trace. Her disappearance is the gravest crisis MI6 has faced for more than a decade. There has been no ransom demand, no word from foreign intelligence services, and no hint of a defection. Should news of Levene’s disappearance leak out, the consequences would be catastrophic. But for disgraced MI6 officer Thomas Kell, the crisis offers a chance for redemption.

London, 1963. The Beatles, Carnaby Street, mini skirts. But the new mood hasn't reached the drab and fearful corridors of MI5 and MI6. Many agents joined the secret service to fight the Nazis. Now they are locked in a Cold War against the Russians. And some of them are traitors. The service has been shaken to its core by the high-profile defections of Cambridge-educated spies Burgess, MacLean and now Philby. Appalled at such flagrant breaches of British security, the Americans are demanding a rigorous review.

But with the growing threat from Moscow Centre, the office has one more job for him. Nat is to take over The Haven, a defunct substation of London General with a rag-tag band of spies.
