Sometimes her eyes seduce. Sometimes they stare straight at the kind of sights most people turn away from. But in the blazing neon and searing sun of Las Vegas, she can't see the man who is watching her and thinking to himself: She is the one ... Psychologist Susan Pulaski, who has a near-empathic gift for understanding the thought processes of criminals, is a consultant for the Las Vegas police force. When the city is galvanized by a brutal murder case - stemming from the death of a young woman who has been buried alive - Police Chief Robert O'Bannon calls on Susan's services. Susan, in turn, relies on the help of O'Bannon's 26-year-old son, Darcy, a high-functioning autistic savant with a prodigious eidetic memory and an instinctive gift for solving puzzles. Darcy's gifts prove invaluable as they follow the trail of a devious madman...who has a special agenda for killing and killing and killing again.
