Some sins can never be forgiven.

DI Jane Phillips was a star detective driven by a relentless quest for justice. But then she stepped outside the law.

Now, demoted and suffering with PTSD, she finds herself facing the deadliest threat of her career -- a serial killer who is preying on vulnerable women, murdering them in a shocking and bizarre ritual.

A master of deception, he selects his victims at random. Or so it seems. But as Phillips investigates, she begins to see a method in the killer's madness. Perhaps these victims aren't random at all...

As the pressure mounts, can Phillips find the link between these ritual murders before the killer strikes again -- or will her dogged determination to solve the case bring his deadly silence to her door?
