An absolutely triumphant bestseller—everywhere hailed as the masterpiece toward which John le Carré has been building since the fall of communism. This thrilling tale of loyalty, betrayal, and international espionage spans the lives of two friends from the riot-torn West Berlin of the 1960s to the grimy looking-glass of Cold War Europe to the present day of terrorism and uncertain new alliances—alliances that aren't always what they seem to be.
