Novichok is the most deadly chemical weapon ever developed. With us to discuss the history of Novichok is Vil Mirzayanov. Vil worked in the secret Soviet chemical weapons laboratory that developed Novichok. He revealed its existence to the world in 1991 and was then arrested by the Russian counterintelligence service and prosecuted in a secret trial. He won his freedom with the help of an international group of scientists, including three who have appeared as guests on this podcast. He then immigrated to the United States and published his story in the book State Secrets. An Insider's Chronicle of the Russian Chemical Weapons Program, published in 2009 by Outskirts Press.
