Nashville 1964. Eighteen-year-old babysitter Paula Herring is murdered in her home while her six-year-old brother apparently sleeps through the grisly event. A few months later a judge's son is convicted of the crime. Decades after the slaying, Michael Bishop, a private citizen, stumbles upon a secret file related to the case and with the help of some of the world's top forensic experts-including forensic psychologist Richard Walter (aka "the living Sherlock Holmes")-he uncovers the truth.
