This book suggests a solution to an episode that has remained a mystery to this day. It is a story involving a king, his mistress, one of Princess Diana's ancestors and a financial genius.The solution offered here is a hypothesis, but as will be shown, a more plausible one than two published well after Wilson's death. These earlier accounts written anonymously by authors with a political axe to grind are printed here as appendices, so that readers can compare the three.
