At Macbeth’s home, the castle of Inverness, Lady Macbeth reads a letter from her husband concerning his meeting with the Witches. She is immediately aware of the significance of their prophetic words and, on being informed that King Duncan will be paying a royal visit to Inverness, makes up her mind to carry out the murder of the king in order to hasten the prophecy. In doing so, she suggests that her husband is weak — he contains too much of “the milk of human kindness.” When Macbeth arrives from the court of Duncan, bearing news of the king’s forthcoming visit, his wife makes her plans clear to him.
