How do you catch a killer who leaves no trace?

A victim killed with a single, precise stab to the heart appears at first glance to be a robbery gone wrong. A caring, upstanding social worker lost to a senseless act of violence. But for Detective Kim Stone, something doesn't add up.

When a local drug addict is found murdered with an identical wound, Kim knows instinctively that she is dealing with the same killer. But with nothing to link the two victims except the cold, calculated nature of their death, this could be her most difficult case yet.

Desperate to catch the twisted individual, Kim's focus on the case is threatened when she receives a chilling letter from Dr Alex Thorne, the sociopath who Kim put behind bars. And this time, Alex is determined to hit where it hurts most, bringing Kim face-to-face with the woman responsible for the death of Kim's little brother - her own mother.

As the body count increases, Kim and her team unravel a web of dark secrets, bringing them closer to the killer. But one of their own could be in mortal danger. Only this time, Kim might not be strong enough to save them...

A totally gripping thriller that will have you hooked from the very first page to the final, dramatic twist.
