This is the inside story of the life and death of Litvinenko and of Russia's new cold war with the west. Harding traces the journey of the nuclear poison across London, from hotel room to nightclub, assassin to victim. It's a deadly trail that leads back to Vladimir Putin, and to a regime exposed by the Panama Papers.

Luke Harding's investigation into the death of Alexander Litvinenko, A Very Expensive Poison, may also help us shed light on the poisoning of Sergei Skripal and his daughter in Salisbury. From the author of the No.1 New York Times bestseller Collusion.
