Adrian Dunbar as Alex Ridley

Who is Alex Ridley?: A retired police officer who worked for 25 years before retiring to a jazz bar, Ridley is our hero who returns to the force. Ridley has gone through it — prior to the start of the first season, his wife and daughter were killed in an arson attack. And his trauma from their deaths looms over his work. He takes an unconventional, sometimes controversial approach to his work, often becoming overly emotionally invested in his cases.

Bronagh Waugh as DI Carol Farman

Who is DI Carol Forman?: Carol was Ridley’s young protege before his retirement — when he returns to the force, he works alongside her to help her solve her cases. She’s fiercely loyal, outspoken, no nonsense, and a warrior for justice. She’s married to Geri and they share son Jack.

Who is Annie Marling? Of course, Ridley needs a friend and confidante, and that person is Annie Marling. Annie was the best friend of his late wife and was the godmather of his daughter Ella, which means she’s basically family. She also owns the jazz bar that Ridley is so very fond of.
