Season 4, Episode 3
When a man is beaten to death in a Turkish bath, suspicion falls on a mentally unstable ex-soldier. But the mystery deepens when the psychologist who had been treating the suspect hangs himself after leaving money to the soldier in his will. World War II veteran Gently finds himself investigating a murder that makes no sense, tied to a military he no longer understands.
Martin Shaw stars as commander George Gently, an uncompromising cop whose reputation for honesty and relentlessness makes him almost as feared among his colleagues as he is among criminals.
