A royal residence beckons for Michael as he is treated to a behind-the-scenes tour of the world's longest vine at Hampton Court Palace. Maintaining a royal theme, Michael is drawn to Esher to visit stately Claremont House, where tragic circumstances led directly to the birth of the Victorian era. Moving up the line to Wimbledon, Michael is challenged to a duel on the common, the site of a historic and memorable duelling event. This journey ends in Teddington, where the story of a Victorian reformer whose work revolutionised the care for those living with learning disabilities is uncovered.
