In this revelatory and shocking two part series, recently declassified documents blow the lid on the most famous royal scandal of the 20th century, and perhaps the most controversial espionage operation in British history. The target? The Royal Family: King Edward VIII, uncle to Elizabeth II, his feisty American lover Wallis Simpson, and the King to be, George VI, father of the queen. The greatest royal romance of the 20th century can now be seen through a unique new perspective: the eyes of those who spied on Edward VIII and Wallis Simpson, creating a secret dossier unlike any other. The result is an extraordinary film which brings an extraordinary story to life as it’s never been seen before.
