Nemesis
A DANGEROUS CHASE. A SADISTIC KILLER.
DS Lucas Walker is on assignment for the AFP, and it couldn't be more personal. This is his last chance to take down Stefan Markovich - the Vandals leader who tried to have him killed after Walker uncovered his drug operation, and has evaded justice for years.
Having tracked Markovich to Berlin, Walker heads to Germany to lure his nemesis out of hiding and into custody. And there is another draw for Walker in Berlin: he finally gets to see Barbara again.
Still dealing with the trauma of her sister's ordeal in outback Australia, Barbara is working her own case - a suspicious death that casts a dark shadow over a peaceful lake colony. Everything about the horrific scene tells Barbara it's murder, and when a second body emerges she realises she is hunting a killer who is watching their victims die in agony.
As Walker and Barbara grapple with their cases, they must also face their feelings for each other - amid the constant threats of the world they inhabit.
