The Swan and Her Brother

Before Diana was known to the world, she and her brother Charles were the youngest Spencers, inseparable and secretly nicknamed Duch and Carlos.

They roamed the family estate, endured harsh boarding schools and frightening nannies, and helped each other through their parents' divorce.

After she married the Prince of Wales, now King Charles III, she became a global icon overnight, devoted to her sons and to people pushed to the margins, even as a savage press pursued her and her royal marriage left her desperately alone.

Charles tried to stay beside her until the black night in August 1997.

That September he stood in Westminster Abbey and spoke his grief before the world, and nearly thirty years later he tells the intimate story of their life together and of the week she died.
