Robert Chase is a man who lives in the shadows. Even to his superiors he is an enigma. He carefully guards his past, not so much because he is ashamed, but more because he insists that no one else be allowed to interpret it. His ability to find almost anyone, anywhere, is legendary inside the CIA, but what his masters truly value is his willingness to walk on either side of a thin red line.
