Mystics in Bali

Catherine "Cathy" Kean is an American (or, depending on the dubbing, Australian) woman who travels to Bali to write a book about black magic. She learns of Leák magic from her lover Mahendra, who says that it is the most powerful form of black magic and that it can be used to kill. After attending a ceremonial ritual, Mahendra agrees to help Cathy study magic. The next night, after a brief thunderstorm, the two meet the cackling leader of the Leák cult, an old witch with long fingernails known as the Queen of the Leák.
