The episode starts with the discovery of a murder of a young public defender. She is a good friend of Joyce's, who does the same job. The key to apprehension is a 45 caliber pistol. Howard is put in charge. Belker has a pet mouse in his pocket. His name is Mickey Belker. Bobby Hill is forced into precinct politics due to the admiration of his fellow black officers. There is also a cocaine bust that leads to some bigger fish. Good, solid episode.
