the long version

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.
