Tracy Borman will tell us of Henrietta Howard, the enigmatic and largely forgotten royal mistress and confidante of King George II. Sarah Gristwood reveals the tale of Mary Robinson - royal mistress, writer and romantic. And Kate Williams tells the story of Emma Hamilton's incredible rise to fame and her passionate affair with Lord Nelson.
