Nathan Blackwell was raised on Auckland's North Shore and attended Westlake Boys' High School before commencing a ten-year career in the New Zealand Police. Seven of those years were spent as a Detective in the Criminal Investigation Branch, where he was exposed to human nature at its strongest and bravest, but also at its most depraved and horrific. He investigated a wide range of cases including drug manufacture, child abuse, corruption, serious violence, rape and murder. Because some of his work was conducted covertly, Nathan chooses to hide his true identity.
