Shelby Anders appears, niece of serial killer James Anders. She is not what the department would expect. The riddle leads Carla to California, where she encounters a corrupt Chief of Detectives. Carmella commits murder working a case; Carole fires her and arrests her. This leads to a showdown between Carole and Carla, who was in charge of the operation. In July, Carole moves up to Police Commissioner and Carla takes over as Chief of Detectives. Lots of promotions, and the return of a couple of former players.
