This tense thriller presents the true story of one of the greatest media scandals in British history " the publication of Andrew Morton's book about Diana, Princess of Wales, which ended her marriage and shook the monarchy to its core. The show moves between Mortons office, the sitting room where the Princess recorded her darkest secrets onto cassettes, and the dingy West London cafe where one of her best friends surreptitiously handed them over. The subterfuge and deception are brought to a scorching climax that changed celebrity, privacy, and the Windsor family forever.
