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.

Patricia Wolf has been a journalist for more than 15 years, a regular contributor to titles including The Guardian, the Financial Times, The Independent and The Telegraph, among others. She grew up in outback Australia, in a mining town called Mount Isa in far north-west Queensland - eagle eyed readers will have spotted a small reference to it in her first book, OUTBACK. Patricia loves the rugged beauty, indigo sky and wide horizons of the outback, but left Australia after university to travel the world and became a journalist. She lives in Berlin, Germany, but the outback always calls her home. In 2019, just before the covid pandemic locked us all in, Patricia spent two months in northwest Queensland, taking a four-week road trip. As she drove and spent nights and days surrounded by the beauty and rugged harshness of the outback, DI Lucas Walker and his stories came to be.
