Mirror, mirror on the wall.... who is the bloodiest countess of them all? Why, no other than Elizabeth Bathory. She was a rich and beautiful noblewoman in mid-16th century Hungary. While she dripped in jewels and velvet, she also was known to soak herself in the blood of young local girls to preserve her youth and beauty. Bathory can be easily considered one of Europe's most notorious female serial killers, even centuries before the term was coined. Her sadistic killing spree could only last for so long, though, before ending in betrayal, torture, and execution. In this episode, Megan and Elizabeth pull apart the bloody and frightening tale of the Blood Countess.
