It was a summer morning in 1982 when soldiers ravaged the village of Chupan Ya, raping and killing women and children. Twenty-three victims are said to lie in the well when Dr. Temperance Brennan and the team from the Guatemalan Forensic Anthropology Foundation now dig. No records were kept. To their families, the dead are "the disappeared." The team is packing up for the day when an urgent satellite call comes in. Two colleagues are under attack. Shots ring out, and Tempe listens in horror to a woman's sreams. Then there is silence. Dead silence.
