The Sinister Mind of Lady MacBeth

On this day, Lady MacBeth receives and reads a letter sent to her from her beloved husband, MacBeth. He explains to her the premonition of the three witches and how they predicted he will be crowned Thane of Cawdor and it actually happened and also how they they predicted he will some day become the King, which means she some day will become the Queen.

She realizes that the only way that her husband will become the King is if they kill King Duncan. As a result of this sinister realization she puts together a plan to ensure the King is killed upon finding out he will stay a night at MacBeth castle. She then prays to the evil spirits that "ten on moral thoughts to unsex her and fill her from the crown to the toe top-full of direst cruelty" because she is afraid her husband is "too full of the milk of human kindness" to carry out the deed himself.
