A U.S. naval counterintelligence officer working to safeguard Pearl Harbor; a Japanese spy ordered to Hawaii to gather information on the American fleet. On December 7, 1941, their hidden stories are exposed by a morning of bloodshed that would change the world forever. Scrutinizing long-buried historical documents, NCIS star Mark Harmon and co-author Leon Carroll, a former NCIS Special Agent, have brought forth a true-life NCIS story of deception, discovery, and danger. War clouds with Japan are gathering and the islands of Hawaii have become battlegrounds of spies, intelligence agents, and military officials - with the island's residents caught between them. Toiling in the shadows are Douglas Wada, the only Japanese American agent in naval intelligence, and Takeo Yoshikawa, a Japanese spy sent to Pearl Harbor to gather information on the U.S. fleet.
