Prime Suspect

The Last Witness Part 1

Now returned to London, with her career stagnating, Tennison, who is under pressure to retire, investigates the murder of a Bosnian Muslim refugee while she copes with "modern" policing, including a supervisor who was once an officer junior to her. As she ends up digging into the past war crimes of recent immigrants, she is reunited with a war photographer with whom she was once involved.
