Early on, Keller's wife, Grace (Maria Bello), in abject anguish, curls up on their bed and sobs that he had made her feel safe and promised lifelong protection; in response, Keller goes mad. He starts his own investigation, apart from the dogged but methodical and plodding work of Detective Loki (an uber-twitchy Jake Gyllenhaal). His search quickly transforms into an interrogation complete with qualities of torture. Striking is his readiness for such ruthless behavior. He's a religious man, a man who, while hunting, steadily recites the Our Father before killing a doe. But he doesn't hesitate to bludgeon his way to the truth.
