Traces of Sin

Original: 愚行録

A year has gone by without any progress on the Tako family's murder, in which an elite businessman, his beautiful and perfect wife, and adorable daughter were brutally killed. Weekly magazine journalist Tanaka gives the case another shot and digs for the truth, but people connected with the case describe a family far-flung from the seemingly picture-perfect couple, and then he discovers a reality more terrifying than anyone had imagined.
