A modern classic about the bitter rivalry between Mary, Queen of Scots, and her cousin and fellow ruler, Elizabeth I of England - retold by Scotland's most popular playwright. Mary and Elizabeth are two women with much in common, but more that sets them apart. Following the death of her husband, the Dauphin of France, the beautiful, and staunchly Catholic Mary Stuart has returned from France to rule Scotland, a country she neither knows nor understands. Ill-prepared to rule in her own right, Mary has failed to learn what her protestant cousin, Elizabeth Tudor, knows only too well - that a queen must rule with her head, not her heart. All too soon the stage is set for a deadly endgame in which there can only be one winner and one queen on the one green island.
