This is the complex and controversial story of a man who killed two people, six years apart, both in mysterious circumstances. It begins with two country cops determined to solve the mystery of who hit and killed Dr Martin Pearson. On Anzac Day 2014, Dr Pearson was on the home stretch of a marathon 1500 kilometre, nine day ride when he was struck. Somewhere out there was the driver. Who was it? Why hadn’t they stopped? The silhouette of a suspect began to emerge, only to reveal a figure who had killed once before – incredibly, six years previously, almost to the day.
