Watch The Private Lives of The Monarchs

One of Tracy's very favourite subjects is the roller-coaster private life of England's most famous - or should that be infamous? - King. The royal palace at Hampton Court and naturally the Tower of London loom large in this testimony. This episode explores how a man capable of great tenderness and love was also given to breath-taking bouts of heartlessness and cruelty.

Tracy is off to France to the magnificent Palace of Versailles to explore the extraordinary 72-year reign of Louis XIV, the self-styled Sun King. What was the truth about the King's very open 'secret' second marriage to Francois D'Aubinge?

King Charles II was not one for serious conversation and hated the business of state, but eventually his amorous exploits began to have a seriously bad effect on his day job.

If ever the image of a monarch was fixed in the public imagination, it's that of Queen Victoria. In this episode Tracy explores two of the most important relationships in her private life; the ones with her husband Prince Albert - with whom things may not have been quite as they seemed - and her eldest son Edward - 'Bertie', whom she came to utterly despise.

The story behind not one but two of royal history's most infamous private lives which are forever intertwined; the tragic 'mad' King George III and his son the Prince Regent. They could hardly have been more different as men and the two hated each other.
