Agent Liz Carlyle Series

An “invisible” is CIA-speak for the ultimate intelligence nightmare: The terrorist who, because he or she is an ethnic native of the target country, can cross its borders unchecked, move around that country unquestioned, and infiltrate its institutions with ease. An invisible on mainland Britain was the worst possible news. For Liz Carlyle, an MI5 Intelligence Officer, this report from MI6 marks the start of an operation that will test her to the limit and put her own life in jeopardy.

Liz Carlyle is a smart, impassioned MI5 intelligence officer. When one of her agents reports suspicious meetings taking place at an Islamic bookshop, she trusts her instinct that a terrorist cell is at work. But she's surprised when her boss suddenly takes her off the case and shocked to hear why: he has received a tip-off that a mole, a "secret asset", has been planted in one of the branches of British Intelligence.

Liz has been transferred to counter-espionage - the hub of MI5 operations during the Cold War, which has been scaled back as anti-terrorism has gained priority. But there's plenty for her to do: There are more spies operating in London in the 21st century than there were during the height of East-West hostilities. And in her new assignment, Liz quickly uncovers a plot to silence one of these Russians: Nikita Brunovsky, an increasingly vocal opponent of Vladimir Putin.

MI5 Intelligence Officer Liz Carlyle is summoned to a meeting with her boss Charles Wetherby, head of the Service's Counter-Espionage Branch. His counterpart over at MI6 has received alarming intelligence from a high-placed Syrian source. The future of the whole of the Middle East is at stake and the deadline for action is drawing ever closer...

MI5 officer Liz Carlyle is posted to Northern Ireland. From the moment she lands in Belfast, danger follows. She soon discovers that the peace process in the province is precarious. Then a source reports strange goings-on at a house on the Irish Sea owned by the Fraternity, an organisation Liz suspects of being a front for renegade former IRA men. Its head is Seamus Piggott, an Irish-American with a gun-running past.

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...

Geneva, 2012. 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.

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.
