This new BBC drama will suck you in from the very beginning, and is written by Harry and Jack Williams, the duo behind gripping drama The Missing. Set in the the remote Scottish Highland village of Braeston, it focuses on the aftermath of the murder of two childhood sweethearts who are killed on their return from honeymoon. Both their families are left devastated, but their world is further turned upside down when the killer arrives badly injured on their doorstep the night after their deaths, leaving them with quite the moral dilemma - avenge their loved one's death, or leave him to the authorities.
(Fans of Game of Thrones will also spot Joe Dempsie (Rob), who plays Gendry on the HBO series. Good to know the actor still isn't off rowing a boat somewhere anyways.)
