San Francisco antiques dealer Jim Brodie receives a call one night from a friend at the SFPD: an entire family has been senselessly gunned down in the Japantown neighborhood of the bustling city. As an American born and raised in Japan and part-owner of his father's Tokyo private investigation firm, Brodie has advised the local police in the past, but the near-perfect murders in Japantown are like nothing he's ever encountered.

With his array of Asian contacts and fluency in Japanese, Brodie follows leads gathered from a shadow powerbroker, a renegade Japanese detective, and the elusive tycoon at the center of the Japantown murders along a trail that takes him from the crime scene in California to terrorized citizens and informants in Japan. Step by step, he unravels a web of intrigue stretching back centuries and unearths a deadly secret that threatens not only his life but also the lives of his entire circle of family and friends.
