The killer is closing in, can she find him before he finds her? When Detective Nikki Parekh receives a set of threatening postcards, she knows it can only mean one thing. The man who escaped arrest after murdering her mother two years ago is back. Each postcard has a similar message: You're next Parekh. As the post marks on the cards gradually get closer to Bradford, Nikki must do everything she can to protect her family and catch the killer before it's too late. But when human remains are found in a remote barn on the icy Yorkshire moors, Nikki's attention is pulled away from her family. When a tattoo on the victim's arm -- the only means of identification -- leads nowhere, the team have already met a dead end. Will the team be able to make a breakthrough before someone else gets hurt, and can Nikki finally get justice for her mother's tragic death?
