In 1998, as Pinochet faces arrest in London, Philippe Sands, approached to advise the dictator, instead chooses to act as a barrister for Human Rights Watch. This decision leads to an eight-year exploration into Rauff's second life, his ties to Pinochet and his role in the atrocities at the heart of the London proceedings. A unique blend of memoir, detective story, courtroom drama and travelogue, drawing on interviews with key players and extensive research in archives worldwide, Sands unveils a hidden double story of mass murder and a disturbing link between the atrocities of the 1940s and those of our own times. As the narrative unfolds, we are transported into a world where the echoes of historical crimes reverberate through the corridors of power, exposing the chilling truth behind the lives of two men and their intertwined destinies on 38 Londres Street.
