The story of a secret affair that would have rocked the establishment and changed the course of history. This series of letters, photographs and first-hand accounts is a true story of forbidden love and inevitable tragedy between Princess Diana's grandfather Lord Fermoy and an ordinary American woman.

For over 40 years the lovesick couple, based on different sides of the Atlantic Ocean, wrote hundreds of letters to each other. Risking everything for the delight of snatched hours and days together, they found in each other what was missing in themselves. Now the silence is broken and we are delighted to present the full account of a story that combines the forbidden love of The Bridges of Madison County with the passion and guilt of Brief Encounter.
