This special episode explores the more difficult times of Her Majesty's long reign. 1992 was the terrible year in which the marriages of Anne, Andrew and Charles collapsed, Fergie appeared topless on the cover of the Daily Mirror, Andrew Morton's incredible revelations about Diana were made public in a bestselling book, and Windsor Castle caught fire. The Queen survived the storm, lived through the scandals and put her house in order, and the royals emerged stronger than ever.
