Fluttering eyelashes, botched beheadings, purloined pearls, bodies tumbling down the stairs, Notre Dame, Holyrood, mermaids, dispatch riders galloping over the moors, intense sexual attraction, three powerful queens, being strangled in your nightie, a thing for men’s legs, a loyal dog, secret codes and spymasters, four centuries of sweet revenge. If you’ve been sold on the notion that history is boring, you have been misinformed. Or badly informed.
