Despite exhaustive searches, no trace of Michael was ever found. Soon after his disappearance, rumors surfaced that he'd made it to shore, where he was then killed and eaten by the local Asmat—a native tribe of warriors whose complex culture was built around sacred, reciprocal violence, headhunting, and ritual cannibalism. The Dutch government and the Rockefeller family vehemently denied the story, and Michael's death was officially ruled a drowning. But doubts lingered and sensational stories circulated, fueling speculation and intrigue for decades. Now, award-winning journalist Carl Hoffman reveals startling new evidence that finally tells the full, astonishing story.

Retracing Michael's steps, Hoffman traveled to the jungles of New Guinea, immersing himself in a world of former headhunters and cannibals, secret spirits and customs, and getting to know generations of Asmat. Through exhaustive archival research, he uncovered hundreds of pages of never-before-seen original documents and located witnesses willing to speak publicly for the first time in fifty years.

Savage Harvest is at once a mesmerizing whodunit and a fascinating portrait of the clash between two civilizations that resulted in the death of one of America's richest and most powerful scions.
