The dead man, Viktor, was his best friend, and Luke knows he would never commit such a horrific crime. When more bodies turn up, Luke is certain the same killer has struck again. Alone, he embarks on an investigation which reaches back through decades to his friend's involvement with a sinister cult and dark secrets are exposed as Luke struggles to keep his own long-buried demons hidden away. And when Luke finds himself in a killer's sights, his search for the truth becomes the fight of his life. Can Luke get justice for Viktor and his daughter and prove his best friend was not a murderer, or will the shadows of the past overwhelm him?
