Zoe Carter stares in horror at the pool of blood lying in the dust at her feet. She has come to the camp site at the bottom of the Mitchell falls, deep in the remote Kimberleys in Western Australia, to meet her boyfriend Martin. But where is he? And where is his boss, the archaeologist Dr Dirk Smithers? Somewhere in this vast, ancient landscape a killer lurks, a killer who will stop at nothing to get what he wants. But what is there in the Kimberleys that's so precious it's worth killing for? Zoe's search for the answer takes her from the Mitchell plateau to Darlington Station, a million acre cattle property in the heart of the Kimberleys, and to Broome where she discovers there is more than one person seeking the prize. But who will get there first? And, at the end of the search, how will Zoe escape from a situation that threatens not only her own life but Martin's too?
