When feminist forensic psychologist, Dr. Ariel Lewis, agreed to help Earl's lawyers understand why he brutally murdered his girlfriend, Carolina, she had no idea what would unravel from the mentally ill man's unconscious mind. Just when Ariel thought that she'd saved him from death row, author Lenore Walker gives us another twist in this psychological thriller. Were there other women who Earl killed? Can she separate what's in his delusional mind from the truth to force the criminal justice system to really work? And most importantly, why does Ariel, known for saving battered women from men like Earl, even care?
