Investigative journalist Scott Carney has spent five years on the ground tracing the lucrative and deeply secretive trade in human bodies and body parts-a vast hidden economy known as the "red market". From the horrifying to the ridiculous, he discovers its varied forms: an Indian village nicknamed "Kidneyvakkam" because most of its residents have sold their kidneys for cash; unscrupulous grave robbers who steal human bones from cemeteries, morgues, and funeral pyres for anatomical skeletons used in Western medical schools and labs; an ancient temple that makes money selling the hair of its devotees to wig makers in America-to the tune of S6 million annually.
