Meet the cast of Unforgotten series two

Respected detective Tessa Nixon was married to the victim, David Walker, when he went missing. They had a son, Jason, who is now in his early 30s. Due to David’s depression, Tessa assumed that he had taken his own life or started again somewhere on his own. She has since remarried, living in the Cotswolds, and is on the brink of retirement when David’s body is discovered.

Lorraine Ashbourne could almost call the Royal Exchange, Manchester her theatrical home, given she's played so many roles on its stage. The veteran actress has a decent TV CV too, with roles in Jericho, The Interceptor and Housewife, 49 to name but a few. And you might also have spotted her on the big screen in films such as Fever Pitch and Jack and Sarah.

Douglas Hodge - Paul Nixon

Tessa's new husband has been a great support to her over the years, but how will he react when her ex-husband's body is discovered? And what might it mean for their relationship?

Douglas Hodge is an Olivier Award winning stage staple who has famously enjoyed great success when starring in Harold Pinter plays. Chances are you've spotted him in Outnumbered, Only Fools and Horses or as Dr. Tertius Lydgate in the BBC's award-winning production of Middlemarch. He played Paul Burrell in biopic Diana, and Sir Robert Loxley in Russell Crowe's Robin Hood.

Will Brown - Jason Walker

Tessa's son Jason is a bit of a loner and his mother worries about him constantly.

You may have spotted Walker on Call The Midwife or in Doctor Who series 9 episode The Highwayman.
