"No divulgar hasta que los implicados estén muertos". Las Guerras de Doblecero. (Intermedio, Bogota:2009) The book is part of my fieldwork in Colombia about the paramilitary. It collects the life history of a major paramilitary leader from Medellin. A former military officer, he witnessed the early developing of the AUC paramilitary umbrella led by Fidel and Carlos Castaño.
