Alex Dryden worked with MI6 and has specialised in Russian affairs for many years. He is now a writer and journalist. When the Berlin Wall came down in 1989, Dryden was working in the Republic of Georgia. From there he travelled across central Asia and Russia, meeting former Soviet national leaders and their replacements, KGB officers and senior mafia figures, all the while watching the statues of Lenin fall as the Soviet Union itself collapsed. He wrote his first book Red to Black in 'sadness and anger at the way the Russian people one more fell under the fist of the KGB'. It's success has lead to three more books charting the rise of Russia's spy elite and its deadly reach across the globe.
