Lawyer and author David Hosp's novels, including Dark Harbor, are best-sellers. Now lawyer Scott Finn is caught in the middle of a touchy case. A policewoman is left for dead in an alley, and when she recovers she points the finger at an El Salvadorian immigrant with gang ties. But all the evidence is pointing the other way. And as Finn digs deeper, he finds a thin line between guilt and innocence.
