Exploiting England's current true-crime craze, he uses social media to titillate and terrorize the public. Ruth is joined in the investigation by her partner, Greg Carver, who is slowly regaining his strength after a run-in with another sadistic criminal. but Greg can't seem to shake the bewildering effects of the head wound which nearly ended him. Are the strange auras blurring his vision an annoying side effect of his injury, or could they be something more—a tool to help him see a person's true nature?
