An honest judge in Medellin, a Maoist guerilla of Peru's Shining Path, the fair-haired Angel of Death in Argentina's Dirty War, the pool-party rich of El Salvador, the disabused revolutionaries of Nicaragua, and the ordinary Chileans who became silent partners in Pinochet's dictatorship-these people live in Latin America, but their stories illuminate the human face of violence all over the world. Tina Rosenberg spent five years trying to understand their world and learning to live with these "children of Cain." Their stories are disturbing precisely because these people are not monsters; the faces in Children of Cain are not those of strangers.
