When Suzanne Crawford is found stabbed to death and her husband Connor is discovered to be missing, it looks like just another tragic case of domestic violence to Detective Ella Marconi. But as the investigation progresses, it becomes clear that all is not as it seems. Why is there no record of Connor Crawford beyond a few years ago? Why has a teenager who worked for the pair gone missing too? And above all, what was the secret Suzanne knew Connor was keeping at all costs - even from her?

As Ella begins to build a picture of the Crawfords’ fractured lives, things around her are deteriorating. Her relationship with a fellow officer is hanging by a thread and her parents seem to be keeping secrets of their own. But Ella only has time for the job she loves, and she knows she has to see her way through the tangled web of deceit and lies to get at the truth - before it’s too late.
