Rain Fall by Barry Eisler

The first in the series is enjoyable but comparatively weak, you can see how Eisler improves as a writer in later works. PW: Set in a memorable noir version of Tokyo (jazz clubs, whiskey bars, "love hotels"), Eisler's rich and atmospheric debut thriller winds its way around the city's extensive rail system and its upscale Western boutiques Mulberry, Paul Stuart, Nicole Farhi London, Le Ciel Bleu, J.M. Weston. The author an American lawyer who has lived and worked in Japan brings to life a complex and most interesting hero: John Rain, a hard and resourceful man in his 40s with an American mother, a Japanese father, a childhood spent in both countries and a stretch with Special Operations in Vietnam that literally made him what he is today a highly paid freelance assassin. The book begins with Rain arranging the death (on the subway) of a prominent government figure by short-circuiting his pacemaker and making it look like the man died of a heart attack. But Rain's relatively simple life suddenly becomes very complicated when he finds himself involved both romantically and professionally with the dead man's lovely daughter, Midori, a talented jazz pianist. Formidable adversaries a nasty CIA agent from John's Vietnam days; a right-wing guru who uses Shinto priests as spies and yakuza gangsters as enforcers; a tireless old cop seem intent on exposing Rain and eliminating Midori. There are several excellent action scenes, an amusing and touching young computer nerd who is Rain's only reliable ally and, most of all, an intriguing and intimate evocation of Japan's intense love-hate relationship with America.
