concise history of the post WWI American intelligence and its early victories with Japanese code breaking. Fargo offers an engrossing tale of how we intercepted, broke, and disseminated intelligence from the Red, Purple, naval, and commercial Japanese codes prior to December 7th. This is a story about the birth pangs of modern intelligence, culminating in the failure to forecast the attack on Pearl. Fargo details the insights we had into Japanese foreign policy and the vagaries of 1930's espionage/counter espionage quite well.
