Try as he might, Gurney can’t resist getting drawn into the murder case—this one, involving a debauched former tennis star and a beheaded corpse. His initial efforts incite fury from both sides of the law: the criminal forces behind it, and the law enforcement personnel who stand to lose everything if Gurney succeeds in uncovering the truth. For the first time in his life, Gurney finds himself on the run but even the risk of losing his marriage, his reputation and his best friend can’t stop his relentless quest for answers. Gurney will learn that justice comes at a great cost.
