Arrested at the murder scene of his mother’s caretaker, William Talent hires Joe Costa to defend him against a murder charge. Prosecutors posit a revenge motive because the mother died of neglect. Costa and police detective Lena Haynes find evidence linking the murder to Lloyd Love, a paroled convict involved in a lonely hearts scam. Love is arrested and Talent released. Months later, Love’s public defender asks Costa to reexamine the case. He questions Love and concludes that four women remain in danger from a serial killer. Legal authorities refuse to act. Costa pursues the killer alone on a dangerous chase that leads him to the Mexican border.
