The final episode takes us to 1952, when tragedy struck as King George VI died in his sleep. We discover what happened as the new Queen began her reign.

The death of Edward VII in 1910 rocks Sandringham and the royals. Plus, how the abdication crisis threw the very future of the house into question.

We go behind the imposing iron gates of the Royal Family's favourite holiday home, first acquired by Queen Victoria as a gift for party-loving Prince Bertie.
