When the body of a woman is found hanging from a tree in her front garden, rookie Detective Morgan Brookes is first on the scene. But Olivia Potter is past saving. And when her husband and daughters cannot be traced, Morgan knows there is more to this tragedy. And then she finds them. Lying huddled together in the dark basement, each of their faces covered with a small cotton cloth, their bodies cold to the touch.

But as Morgan kneels beside the family, she realises that one of the girls is still breathing. As she holds Bronte’s fragile hand in hers, begging her to hold on, she vows to find out who has done this.

Every day Morgan wakes at 4.25 a.m., her old insomnia now mixed with a new fixation on the case. But every clue about the murdered family leads to a dead end. Until, trawling through old files, she discovers a link to a cold case from years ago. Another family was found murdered, their innocent faces covered with white cloths.

When Morgan returns to the scene of the crime to discover more about this forgotten case, she finds another body. With Bronte still unconscious in hospital, Morgan must act fast to solve this case before the killer returns for the girl left alive…
