Morven Christie (who played lead character Lisa Armstrong) previously announced she would leave the series after season two, and has since been replaced by COBRA actress Marsha Thomason.

Written by Daragh Carville (Being Human), the third season introduces us to Lisa Armstrong's replacement, DS Jenn Townsend, who has just arrived in Morecambe.

According to the synopsis, DS Townsend is "immediately thrown into the deep end when a body is found in the bay on her first day in the job. She must get under the skin of a grieving and complicated family if she has any chance of solving the premature death of an aspiring young boxer. While she’s eager to give the family answers, she also needs to prove herself as the team’s newest recruit."

Who is DS Jenn Townsend? Jenn is Morecambe CID’s new Family Liaison Officer, who struggles to balance the pressures of work and her home life.

“Jenny’s super-nervous on her first day," Thomason said. "The way she comes in and is straight onto a case, it’s a lot. She’s very good at her job, but she’s in a bit of a crisis when we meet her. When she gets to work, she’s just on it and focused and getting it done. She doesn’t have to think too hard about that, it just comes naturally to her. It’s a crazy first day."

Where have I seen Marsha Thomason before? She played Diana Berrigan in White Collar, and Naomi Dorrit in Lost. She's also starred in COBRA, NCIS: Los Angeles, Magnum PI, and Safe House.

Daniel Ryan plays DI Tony Manning

Who is DI Tony Manning? DI Tony Manning returns from the earlier seasons and will be DS Jenna Townsend's new boss. He’s a “dedicated, down-to-earth leader” who is devoted to his team and to his job. Last season we saw more of his home life, with Manning struggling to cope with the breakdown of his marriage.

What else has Daniel Ryan been in? Viewers will probably recognise stage and screen actor Daniel Ryan from the likes of Innocent (in which he played Phil Collins) and ITV’s Vera, in addition to Mount Pleasant, in which he played Dan. You may also have seen him in The Government Inspector, The Whistleblowers, Cold Call, Home Fires, or Doctor Who.
