'Incredibly well-informed and immensely readable - a book that will be argued over for years to come.' - Jonathan Haslam, author of Russia's Cold War: From the October Revolution to the Fall of the Wall'A wonderful Cold War parable in which both protagonists, Berlin and Deutscher, the liberal and the Marxist, reveal just how crooked the timber of humanity can be, especially when ideas collide with events. Caute metes out morality and mitigation in equal measure - a rare and wise combination.' - Petre Mandler, author of Return from the Natives: How Margaret Mead Won the Second World War and Lost the Cold War
