The story is about Dr. Joe O'Loughlin, who seems to have a perfect life-a loyal wife, a lovely daughter, a successful career as a clinical psychologist, high media appearances, and a book publishing contract. Joe became a hero on the Internet when he saved a patient who was going to jump from the tenth floor to commit suicide in the hospital where he worked. Senior police officer Inspector Vincent Ruiz and his young partner Sheriff Riya Devi were sent to investigate after the body of a young woman was found in a shallow pit in West London Cemetery. As a successful writer, Dr. Joe is often consulted by others, but when he meets Sheriff Devi, he offers too much help. Does the adventurous, rule-breaking Joe have anything to hide? He has recently been diagnosed with a debilitating disease, which may explain his behavior. With the deepening of the investigation into the death of Catherine, people can not help but wonder whether Joe has a secret side, whether his work as a clinical psychology has made him form a criminal thinking tendency, or even worse?
