Exotic dancer, actress, WWI spy: Who was Mata Hari?

The notorious World War I spy Mata Hari was executed 100 years ago for being a double agent. But was she? New scholarship casts doubts on the lore surrounding Mata Hari, whether she was really a spy and a wily seducer of men. An exhibition devoted to her opens this weekend at the Fries Museum in her hometown in Holland. Last year, the Dutch National Ballet put on a production based on her life.
