Yamato

Yamato is a tense alternative-history thriller set in 1953 during the American occupation of Japan.
Lieutenant Harvey Brice, an army intelligence officer, is found in his apartment with a bullet in his head. But was it suicide or homicide? World-weary CIA agent Ralph Carnaby, together with his Japanese-American sidekick, Dan Morita, are unwittingly drawn into a conspiracy which is unfolding in the very heart of the occupation headquarters in Tokyo--a conspiracy which ultimately threatens to change the course of Japan's postwar history.
With a style reminiscent of Robert Harris' Fatherland, Clare weaves a web of intrigue and espionage which sees Carnaby and his fellow agents pitted against internal rivalries, yakuza gangsters, and a far more menacing and invisible force, in a nail-biting race against time.
