The discovery of nine human skulls leads Lilly back to George Marks, the serial killer she was unable to incriminate months earlier, and who walked away a free man. As the detectives reinvestigate his mother's murder from 1972, George is forced to emerge from hiding to face Rush again. This time, their very lives are at stake in their final showdown.

- As Jeffries and Vera see at the gun store, George Marks may see himself as Orion the hunter. One of the versions of the myth of Orion says that he was the lover of Artemis, the Greek goddess of moon and hunt and that he once tried to rape her; outraged, the goddess killed him. That's more or less what happens between George and Lilly: he brings her to the "woods" and assaulted her, not physically, but mentally by making her tell him all her terrible childhood memories. After that, she shot him to death in self-defense.
