Sergei Skripal and his daughter Yulia were enjoying a rare and peaceful Sunday spent together, completely unaware that they had been poisoned with the deadly nerve agent Novichok. Hours later both were found slumped on a park bench close to death. Following their attempted murders on British soil, Russia was publicly accused by the West of carrying out the attack, marking a new low for international relations between the two since the end of the Cold War. This is the definitive account of how Skripal’s story fits into the wider context of the new spy war between Russia and the West. The Skripal Files explores the time Skripal spent as a spy in the Russian military intelligence, how he was turned to work as an agent by MI6, his imprisonment in Russia and his eventual release as part of a spy-swap that would bring him to Salisbury where, on that fateful day, he and his daughter found themselves fighting for their lives.
