The new series of Shetland starts on Friday on BBC1 at 9pm. The television drama based on Ann Cleeves' award-winning Shetland novels.

When a young man disappears on the ferry crossing from Aberdeen to Shetland, and a small boy ends up in intensive care, DI Jimmy Perez and his team become convinced the two events are connected.

Douglas Henshall returns as DI Jimmy Perez, aided by Tosh (Alison O'Donnell) and Sandy (Shetlander Steven Robertson).
