From the author of the Sunday Times number one bestseller comes the sixth instalment of the Robert Hunter series!

A freak accident in rural Wyoming leads the Sheriff's Department to arrest a man for a possible double homicide, but further investigations suggest a much more horrifying discovery - a serial killer who has been kidnapping, torturing and mutilating victims all over the United States for at least twenty-five years.

The suspect claims he is a pawn in a huge labyrinth of lies and deception - and he will now only speak to Detective Robert Hunter. These interviews begin to reveal terrifying secrets that no one could've foreseen, including the real identity of a killer so elusive that no one, not even the FBI, had any idea he existed . . . until now.
