The plot of Hideo Yokoyama’s Six Four begins in 1989, with the murder of Shoko, a seven-year-old girl. Fourteen years later the perpetrator has yet to be apprehended, and the case is viewed as Tokyo’s police force’s most damning failure. The commissioner of police plans to visit the home of Shoko’s father to pay his condolences, and to insist that the murderer will be brought to justice.
