In the Australian Outback, when five women set out on a hike for a corporate retreat but only four return, Federal Police Investigator Aaron Falk is drawn into the case. The missing woman was to be a key witness against the company, giving her coworkers plenty of motive to want her dead.

After reading The Dry, I knew I had to pick up the second Aaron Falk mystery. Although the mystery itself was good, showcasing how quickly a team can fall apart when things go wrong, there was no reason this book needed to be a sequel. Falk himself added almost nothing to the plot and could have been easily removed.
