In this intense sequel to Dead Man's Rule, Karl and Gunnar Bjornsen have built a pharmaceutical empire from the ground up. Now they are developing a revolutionary new drug, a neural stimulant that increases strength and intelligence, but its potential for success is rapidly destroying them. Warring for control of the company and the drug, Karl sues Gunnar, and Gunnar hires Ben to defend him. But the case involves more than bitter sibling rivalry. Signs of embezzlement, black market deals, and the grisly consequences of the Bjornsens' new drug begin to emerge. Soon, Ben and his wife, Noelle, find themselves in Norway where the case takes a personal and violent turn.
