Measured, insightful, and valuable to students of Cold War or espionage history. Library Journal Mr. Garthoff is uniquely qualified for such a study... Much of his book is based on personal conversations with Soviet officials-including intelligence officers who spoke candidly about their own service-and declassified Soviet documents. -- Joseph C. Goulden The Washington Times
