She begins keeping a diary, noting down everything she is likely to forget. A killer ready to strike again. When the body of a woman is found at the cairn and one of Hanne's shoes is found nearby covered in the victim's blood, her team must discover if this new murder connects to their old one. And a boy who holds their secrets in his hands . . . 'Scandi-noir at its powerful bleakest' Daily Mail
