One of America’s greatest unsolved mysteries, and the two women at its core; One black, one white. One poor, one rich. They never actually met. But their lives came to intersect through one tragic day when Mary Pinchot Meyer was mysteriously murdered on her daily walk in broad daylight in 1964. A black man stood accused, and a barrier-breaking civil rights lawyer, Dovey Roundtree, rose to his defense. Award-winning journalist Soledad O'Brien weaves a tale of crime and culture that still resonates with our socio-political climate today.
