Treasure and Dirt, by Chris Hammer

When an opal miner is found crucified Sydney homicide cop Ivan Lucic heads outback to Finnegans Gap to investigate. He is joined by a new junior partner, Nell Buchanan, who has history in the town. Ratters, battling billionaires, a religious cult and corruption at many levels make this anything but cosy crime. The characters are well drawn, with breadth and depth, although rather too many elements tend to blur the picture at the conclusion. This is the first novel in a series featuring this unlikely pair of detectives, whose personal demons have minimal impact on their investigative skills.
