Little House on the Prairie gave America something it did not know it needed as desperately as it turned out to need it — nine seasons of the Ingalls family navigating the beautiful and brutal landscape of the American frontier with a decency and a warmth and a moral clarity that the 1970s, in all their complicated cultural upheaval, found genuinely sustaining, a weekly reminder that the values the country was arguing about had once been simply lived by people who had no time for argument and every reason for faith.

The show became one of the most beloved in the history of American television, and the cast that brought Walnut Grove to life became, in the particular way that only the most genuinely affecting television produces, people that the audience felt they personally knew and personally loved across nearly a decade of Saturday nights. What the audience did not know — what the careful, wholesome image that the show projected so completely and so consistently was specifically designed to prevent them from knowing — was that the world behind the cameras contained the full, complicated, sometimes painful human reality that exists behind every production that runs long enough and involves enough people living closely enough together to generate the kind of stories that press departments earn their salaries containing. The secrets that are finally coming out about Little House on the Prairie — about the relationships and the rivalries and the creative tensions and the personal struggles that the cast and crew carried through nine seasons of one of the most demanding productions on American television — are not the kind that destroy a legacy but the kind that complete it, filling in the human dimensions of a story the audience always loved and making it, for the first time, fully and honestly whole.
