On a hillside in Tennessee, human bodies decompose in the open air, aided by insects, bacteria, and birds, unhindered by coffins or mausoleums. At the Body Farm, Bill Bass's research has revolutionized the field of forensic science, particularly by pinpointing "time since death" in murder cases. A scientist and an engaging storyteller, Bass shares his most intriguing work: his revisit of the Lindbergh kidnapping and murder, 50 years after the fact; the mystery of a headless corpse whose identity astonished the police; and the telltale bugs that finally sent a murderous grandfather to death row.
