The police never notice the small detail in the background of a police photograph of an abandoned car. A detail that tells Detective Inspector Napoleon Bonaparte plainly that the mysterious disappearance of Luke Marks near Windee Station is anything but accidental. Why had Luke Marks driven specially out to Windee? Had he been murdered or had he, as the local police believed, wandered away from his car and been overwhelmed in a dust-storm? Bony feels the answers lie somewhere in the sands of Windee.
