A progressive Boulder District Attorney, perceived by some to be too lenient in his treatment of criminals, is brutally murdered. The prime suspect turns out to be an attractive female detective, who, along with her male partner, a crusty veteran of the department, is among the first to investigate the crime scene. A tangled web of relationships connects Alan Gregory, a clinical psychologist in private practice, to this case in a variety of ways. His involvement, in turn, connects the murder indirectly to a vengeful plot by a disturbed young man and woman. Both victims of violent crime, they feel that they have been further violated by the system's failure to adequately punish the persons responsible. They plan an extraordinary series of bombings to bring the impact of senseless violence to the attention of the public and to make public officials experience their pain and loss. The result is a riveting account of Alan's efforts to identify exactly who the bombers are and prevent what they have planned.
