Ashley Dyer books in order

Detective Greg Carver, who has for months been chasing after a vicious killer dubbed the Thorn Killer, is shot in his own home.

Although his reliable partner, Ruth Lake, is with him, she instead clears all the evidence, rather than calling for help.

Carver however isn’t dead.

As he wakes up in the hospital with no recollection of what happened, Carver is convinced that Thorn Killer was behind his attack, despite having no evidence to back his claims.

Carver however won’t be cowed into submission. He will do whatever it takes to catch the killer before more blood is shed.

Coaxed into visiting a “crime scene” by a puzzling digital request, Ruth Lake is shocked when she finds a ghastly tableau surrounded by a group of onlookers.

This is just the latest “art installation” by a deranged serial killer dubbed the Ferryman.

Fully taking advantage of Britain’s current obsession with true-crime television show, Fact or Fable, the killer uses social media to frighten the public.

Joined by her partner Greg Carver, who is gradually recovering after an encounter with a brutal criminal, Ruth will stop at nothing to catch the sadistic killer turning his victims into grisly works of art.
