Black Sheep C.J. Lyons It's the one mystery Supervisory Special Agent Caitlyn Tierney has never solved: her father's unexplained suicide after arresting his best friend for murder. It drove Caitlyn to become one of the FBI's best agents-and often the most unorthodox. Her latest case is no exception when the man she holds responsible for her father's death asks for help in finding his missing daughter. Caitlyn's search brings her back to her North Carolina hometown, now vibrant with new money, old lies, and an unknown enemy who will do anything to keep Caitlyn from the learning the truth-and who will kill to keep it buried.
