The synopsis continues: "Tosh must pause her investigation into a string of mysterious animal deaths to help Calder find the witness before it’s too late.

"However, Calder's hostility to Shetland will challenge Tosh's view of her adopted home, and their journey into the darker recesses of Shetland's past and present will test this fragile new partnership."

Jensen previously told RadioTimes.com that Calder's arrival will "bring a whole new dynamic to everyone else", with this season being the first not to feature Douglas Henshall's DI Jimmy Perez.

She continued: "It's kind of almost more about the other people – about how Alison and all the other characters are going to relate to Ruth Calder, so that'll be really interesting."

Shetland season 8 will air on BBC One on Wednesday 1st November at 9pm. Check out more of our Drama coverage or visit our TV Guide and Streaming Guide to find out what's on.
