In March 2020 a couple disappears from the remote Wonnangatta Valley, leaving a burnt-out campsite. Russell Hill and Carol Clay are secret lovers, and at first it seems they might simply have started a new life elsewhere. But the police become increasing convinced that they have been the victims of foul play, even though their bodies have not been found. So begins a painstaking investigation, tracing the driver of every car that was in the area, checking their stories and alibis. Ultimately, after more than a year's work, there's only one driver who cannot be eliminated: Greg Lynn, a Jetstar captain. Is it possible that this highly successful professional pilot is a killer? Could he be responsible for a number of other mysterious disappearances in the Wonnangatta Valley? And how can the police charge him, given that there are no bodies, no witnesses and no clues as to how Russell and Carol were murdered? This is the gripping inside story of the pursuit and trial of Greg Lynn.
