Vast and revelatory, Dan Gretton's I You We Them is an unprecedented study of the perpetrators of crimes against humanity: the 'desk killers' who ordered and directed some of the worst atrocities of the modern era. From Albert Speer's complicity in Nazi barbarism to cases of ecocide and the deaths of activists, Gretton shines a light on the figures 'who, by giving orders, use paper or a phone or a computer to kill, instead of a gun.' Over the past twenty years, Gretton has interviewed survivors and perpetrators, and pored over archives and thousands of pages of testimony. His remarkable insight into the psychology of the desk killers is deepened by the intimate journey he travels with his readers.
