While Britain is obsessed with the newest hit true-crime television show, Fact, or Fable? detectives Ruth Lake and Greg Carver are tormented by a fiendish flesh-and-blood killer on the loose.
Lured to a “crime scene” by a mysterious digital invitation, Ruth Lake is horrified by what she finds: a bizarre and gruesome tableau surrounded by a crowd of gawkers. The deadly work is the latest “art installation” designed by a diabolical criminal dubbed the Ferryman. Not only is this criminal cold-blooded; he’s a narcissistic exhibitionist desperate for an audience. He’s also clever at promoting his deadly handiwork. 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 that 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?
