Kobok, a rough-edged and always on the edge ATF agent, is a rounder, a brawler, sometimes a drunk, and always in conflict with an inept government management. His rookie partner has matured into a streetwise veteran, and the always explosive Dallas Homicide Detective Bull Hooper remains the toughest guy on the block. Homer Wayne DuPree, self-made multimillionaire waste disposal magnate, is stunned when his long-time wife dies. He marries a prostitute. She and her lover decide to murder the old man for his fortune. They learn that murder is an inexact science and some folks take more killing than others. Kobok, convinced he's seen it all, soon realizes that identifying the players in the business of assassination is a whole new world.
