In late 2018, a young American missionary who kayaked onto a remote beach in the Andaman archipelago of the Indian Ocean and was killed by Indigenous islanders wielding bows and arrows. News of that fatal encounter made the world aware that such a place existed in our time: an island whose hunter-gatherer inhabitants still live in near-total isolation. Author and historian Adam Goodheart tells the stories of others drawn to the island through the centuries, discusses other Andaman tribes’ encounters with the outside world, and highlights how the modern age is drawing closer to their shores.
