Shetland series 10 promises “epic stories, darkness, intrigue, a pinch of humour and a big dollop of Scottish trustworthiness“

Alison O’Donnell and Ashley Jensen are amongst those in a range of interviews the BBC has released for upcoming Shetland series 10. Shetland returns for a tenth series on BBC One and BBC iPlayer from 9pm on Wednesday 5 November 2025.

What do we know about series 10 and its epic stories

Calder and Tosh are drawn to a remote village following the sinister murder of an elderly woman. As they begin to unravel life in this close-knit community, shocking, long-buried secrets rise to the surface with unexpected consequences for all – including the team.

In the isolated hamlet of Lunniswick, the body of the retired social worker Eadie Tulloch has been out in the elements for a number of days. A picture of loneliness begins to emerge as Eadie had not spoken to her son Ed in years. Old friend Arthur Mair is too busy caring for his ailing wife Lana, while their house is full with daughter Isobel, her struggling husband Tom, and their heavily pregnant teenager, Jess having recently moved in.

Attentive local Colin Waite turns Calder and Tosh’s focus to David Powell, an anxious, young neighbour with a troubled past. His overly protective mum, Gina, blocks all questions while trying to figure out what her son is hiding.

Suspecting the residents of Lunniswick are holding back about their relationships with Eadie, Calder and Tosh begin to unravel a complicated web of lies. Worse still, there’s a personal link to the case for one of the team, testing loyalty to the limits.

Who is interviewed

The interviews cover the stars as well as introducing the guest stars — L-R: Top: Arthur Mair played by Clive Russell, Lana Mair played by Ellie Haddington, and Tom Jameson played by Niall Macgregor.

There’s plenty to get into, and you’ve a week to get ready for a return to Scotland. We’ll leave you with the words of Alison o’Donnell (who provided the quote in the title) talking about the secret of the success of Calder and Tosh:

They have quite distinctive policing styles but between them they’ve got everything covered. I also find their relationship to be down-to-earth and relatable. The comedy flourishes that the writers give us are a lovely counterpoint to the darkness of the drama and we always have a lot of fun with those.
