How far would you go to hold on to the people you love? When Olivia Brookes calls the police to report that her husband and children are missing, she believes she will never see them again. She has reason to fear the worst; this isn’t the first tragedy that Olivia has experienced. Now, two years later, Detective Chief Inspector Tom Douglas is called in to investigate this family again, but this time it’s Olivia who has disappeared. All the evidence suggests that she was here, in the family home, that morning. But her car is in the garage, and her purse is in her handbag – on the kitchen table. The police want to issue a national appeal, but for some reason every single picture of this family has been removed from albums, from phones, from computers. And then they find the blood… Has the past caught up with Olivia? Sleep Tight – if you can. You never know who’s watching.
