This story is true ... Most of it.
The Spy That History Erased is a fictionalized version a German man's Faustian Bargain with the Japanese Consulate in Honolulu prior to the attack on Pearl Harbor. It's the story of how he and those in and out of government had what others dream of having: the opportunity to change history. Some succeeded. Some didn't ...
It's a story that haunts us with these questions:
What if the Honolulu FBI had acted on its suspicions and questioned that man?
What if American intelligence-because the FBI had done its job-needn't have relied on code breaking or a prompt reading of intercepts to fathom Japanese intentions?
What if the administration had prior knowledge of an attack because the FBI had done its job and informed American intelligence of Japan's plans?
What if Japan had decided not to attack Pearl Harbor because the Honolulu FBI arrested their German agent?
