San Francisco antiques dealer Jim Brodie recently inherited a stake in his father’s Tokyo-based private investigation firm, which means the single father of six-year-old Jenny is living a busy intercontinental life, traveling to Japan to acquire art and artifacts for his store and con­sulting on Brodie Security’s caseload at home and abroad.

One night, an entire family is gunned down in San Francisco’s bustling Japantown neighbor­hood, and Brodie is called on by the SFPD to decipher the lone clue left at the crime scene: a unique Japanese character printed on a slip of paper drenched in blood.

Brodie can’t read the clue. But he may have seen it before --- at the scene of his wife’s death in a house fire four years ago.

With his deep array of Asian connections and fluency in Japanese, Brodie sets out to solve a seemingly perfect crime and at the same time learn whether his wife’s tragic death was more than just an accident. And as he unravels a web of intrigue stretching back centuries and con­nected to the murders in San Francisco, the Japantown killer retaliates with a new target: Brodie’s daughter.
