With this scene a new figure appears upon the stage. It is unnecessary to repeat here what has been said in the Introduction as to the character of Lady Macbeth; but we may note the striking fashion in which that character is revealed to us. The lady enters reading a letter in which her husband tells of his encounter with the witches, and of their prophetic greeting. He has already made inquiries as to the witches, and has learned that their prophecies always come true. So he writes to her that she may rejoice in the greatness that is promised to her as the future queen.

It is interesting to note that there is no suggestion in the letter of any criminal attempt to hasten the fulfilment of the oracle. Macbeth must have written while in the same mood of half-formed resolve to bide his time that marks the close of scene . But Lady Macbeth has no intention of waiting for chance to crown her. She prefers "the nearest way," that of speedy and violent action. As yet she knows nothing of the obstacle which the proclamation of Malcolm as heir-apparent puts between Macbeth and the crown.

The only obstacle she sees lies in the character of her husband. He is ambitious, but is unwilling to play false to attain the objects of his ambition. Yet she is so sure of her influence over him that she prays he may return speedily, in order that she may inspire him to action and drive out any scruples that may bar the way to his goal. When she hears of Duncan's approaching visit, she realizes instantly that Fate has delivered the king into her husband's hands, and invokes the powers of evil to strengthen her for the terrible deed that must be done at once. On Macbeth's arrival she takes the matter into her own hands; she does not argue or persuade, but with quiet determination assures him that Duncan will never leave their castle alive, and that she will arrange all the details.

Macbeth is, as it were, stunned by her decision. He has, indeed, meditated the murder of his master; but he has by no means decided upon it, and he would like more time for consideration. His wife, however, cuts the scene short, bidding him show a friendly face to his royal guest and leave all the rest to her.
