Both Sides of the Fence: A Life Undercover

As one of a handful of UK police officers trained in SAS deep-cover surveillance, David Corbett infiltrated the toughest communities, living among junkies, prostitutes, murderers, and firearm dealers, in order to gather evidence that would lead to dozens of convictions. He trained in urban and rural surveillance and invented a fictional past for himself. Like Donnie Brasco, the legendary US cop who won the trust of the Mafia, Corbett risked his life every day—one false move and his cover would have been blown. Corbett's work led to 31 convictions and commendations from the Chief Constable and a Crown Court judge but, without any form of counselling, the stress took its toll and he was forced into early retirement. Now, betrayed by the force that sent him out on these dangerous missions, Corbett reveals the gripping story of life in the perilous world of an undercover cop.
