Psychologist, Alan Gregory, soon finds himself smack in the middle of the case, brought in by his close friend and Lucy's partner, Detective Sam Purdy.

Alan knows all the players well. In fact, his wife is a prosecutor in the District Attorney's office, and worked for Royal. Enter new patient, Naomi Bigg. She's come to Dr Gregory seeking help with her son, cagily talking about bombs, Columbine, vengence, and parental responsibilities. When a bomb is found in Royal Peterson's house, and it becomes apparent that Naomi Bigg and the Peterson crime may be connected, Gregory has to wrestle with the ultimate psychologist's dilema. Which is more important, his ethical duty to his patient, or his moral obligations to the community.
