In Inverness, Macbeth’s castle, Lady Macbeth reads to herself a letter she has received from Macbeth. The letter announces Macbeth’s promotion to the thaneship of Cawdor and details his meeting with the witches. Lady Macbeth murmurs that she knows Macbeth is ambitious, but fears he is too full of “th’ milk of human kindness” to take the steps necessary to make himself king . She resolves to convence her husband to do whatever is required to seeze the crown. A messenger enters and informs Lady Macbeth that the king rides toward the castle, and that Macbeth is on his way as well. As she awaits her husband’s arrival, she delivers a famous speech in which she begs, “you spirits, That tend on mortal thoughts, unsex me here, And fill me from the crown to the toe top-full, Of direst cruelty”. She resolves to put her natural femininity aside so that she can do the bloody deeds necessary to seize the crown. Macbeth enters, and he and his wife discuss the king’s forthcoming visit. Macbeth tells his wife that Duncan plans to depart the next day, but Lady Macbeth declares that the king will never see tomorow. She tells her husband to have patience and to leave the plan to her.
