Forensics confirmed two people had gone over Whale Watchers' Point, a 540-metre sheer-faced cliff. Evidence proves with 7 metres to impact, travelling close to a hundred miles an hour; the two were still together, yet only one hit the rocky shoreline below. Six months earlier. Sam Maddox, head of genetic engineering, answers his phone. This one-minute call distracts him and the two seconds when a phial mishandled by Dr Maria Enrique spills one fluid ounce of active DNA. The sequence of events to follow? No one could have foreseen. Challenging the police and a respected neurologist to believe or accept their own conclusions.
