Treachery begins at home Back in London after a gruelling operation in Paris, Liz Carlyle has been posted to MI5’s counter-espionage desk. Her bosses hope the new position will give her some breathing space, but they haven’t counted on the fallout from Putin’s incursions into the Ukraine. Discovering that an elusive Russian spy has entered the UK, Liz needs to track him down before he completes his fatal mission – and plunges Britain back into the fraught days of the Cold War. Meanwhile, following the revelations of whistle-blower Edward Snowden, the intelligence services are in the spotlight. In response to the debate raging around privacy and security, they hire Jasminder Kapoor, a young and controversial civil rights lawyer, to explain the issues to the public. But in this new world of shadowy motives and secret identities, Jasminder must be extra-careful about whom she can trust… Gripping, nail-bitingly tense and drawn from her own experience as Head of MI5, Stella Rimington's latest thriller brings the new Cold War vividly to life
