In 1932, Japan was in crisis; naval officers had assassinated the prime minister and the military had a stranglehold on the government. Into this maelstrom stepped Ambassador Joseph C. Grew, America's most experienced and talented diplomat. For the next decade, Grew attempted to warn the world about the risks of Japan's nationalism and militarism, while also trying to stabilize Tokyo's increasingly volatile foreign policy. Drawing on Grew's diary, Steve Kemper brings to life a man who risked everything to avert another world war.
