At least four settlers on the Galápagos island of Floreana vanished or died in the early nineteen-thirties, under circumstances that were contested long afterward among some of the survivors. A 2014 documentary, "The Galápagos Affair: Satan Came to Eden," gave the subjects' written accounts a scrupulous airing, letting the settlers tell their stories in their own often conflicting words. "Eden," which was written by Noah Pink ("Tetris"), begins in 1929, with the Great Depression in the background and drastic life-style reassessments under way.
