The Dry (Aaron Falk, #1)

In the grip of the worst drought in a century, the farming community of Kiewarra is facing life and death choices daily when three members of a local family are found brutally slain.
Federal Police investigator Aaron Falk reluctantly returns to his hometown for the funeral of his childhood friend, loath to face the townsfolk who turned their backs on him twenty years earlier.
But as questions mount, Falk is forced to probe deeper into the deaths of the Hadler family. Because Falk and Luke Hadler shared a secret. A secret Falk thought was long buried. A secret Luke's death now threatens to bring to the surface in this small Australian town, as old wounds bleed into new ones.
