Marie Arnoux was a young Haitian woman who lived in Port-au-Prince and was hired as a guide to Indiana Jones and George McHale when they needed to travel to Zile Muri-yo in 1943. She was a tall, beautiful woman, with even features, smooth skin, and lovely black hair. She had a younger brother, Alain Arnoux, who resembled her, and a cousin, André. She was also related to Boukman, and was secretly a mambo, or voodoo priestess, like her mother had been. She was fluent in French, Creole, English, and the dialect spoken on Zile Muri-yo.
