Between the Lines (1992)

This show is set in the Complaints Investigation Bureau (C.I.B.), the department responsible for investigating other police officers, of London's Metropolitan Police [the British counterpart to the Internal Affairs Bureau (I.A.B.) of a U.S. city's police force]. The first two seasons had stories based around various different aspects of the darker side of the police, ranging from such topics as petty corruption, racism, and sexual harassment through to grand conspiracy, with some plot threads running through the season over several episodes. The series also dealt with the personal lives of it's less-than-clean-cut characters, particularly the womanizing lead character Tony Clark, and is also notable for its inclusion of a lesbian character in a major role. In the third and final season, the focus changed significantly, moving away from the police force to other areas of security and espionage.
