In late November 2006 the whole world was shaken by a ruthless assassination in London of former lieutenant colonel of the FSB (the Russian security service and a successor to the KGB) and British citizen Alexander Litvinenko. This has been the most notorious crime in the past 30 years committed by Russian intelligence on foreign soil. Former Russian military intelligence officer and international expert in special operations Boris Volodarsky shows how the Russian poisoning operations started with Lenin and his Cheka, the predecessor of the KGB with intelligence operatives creating poisons and delivery methods as well as planning and carrying out poisoning operations all over the world in order to eliminate the enemies of the Kremlin.
