In a fish market shed in Apollo Bay, a young woman is found murdered—bound and savagely mutilated. Once a beauty, she's now barely recognizable, and with a message carved into her stomach, but who is it for?

Melbourne Homicide Detectives Carson, a former criminal profiler for the FBI, and his partner Declan are tasked with figuring it out before the killer strikes again. And he will—because to him, murder is more than just the killing, it is justice.

As more victims show up, and the kidnapping, torturing, and mutilation show no sign of stopping, Carson and Declan are thrown into a whirlwind of inconceivable evil; a dangerous game of cat and mouse with a sadistic psychopath.

As Carson struggles to link the seemingly random victims and their locations, the killer calmly plans his next move.
