It would plainly seem, therefore, that Macbeth had broken this enterprise to her, and urged it on her, even before the king had determined to come to his castle, and that he intended to make time and place. This would account completely for her opening speech, and for the fact that he does not make any explanation to her of his intentions other than by his look and intonation when they first meet; for certainly there is nothing in the play about the time and place of the murder except as herein indicated. It would also explain the surprise of Lady Macbeth when she hears that her husband is coming, and the king after him: “Thou’rt mad to say it,” she says; and “the raven himself is hoarse that croaks the fatal entrance of Duncan under my battlements.” The time and place had made themselves, then; and it is on hearing this that she suddenly changes from calm to vehement emotion, and makes that wonderful apostrophe to the spirits to unsex her. She sees that all has been resolved, and that she has need of her utmost resolution. There is no warrant of any kind that, in the simple words, “And when goes hence,” she meant more than she said. It was the most natural question that she could possibly ask. Granting that she intended equally with him to commit the murder, what is more natural than that she should wish to know how long the king was to stay, so as to know how soon it was necessary to carry out the plan of murder, and what time there was in which to make all the arrangements? Not only Macbeth pauses after saying “To-morrow” (so, at least, is the punctuation in all editions), before adding “as he purposes,” but Lady Macbeth, in her answer, says that she sees in his face that he intends that “never shall sun that morrow see.” Yet, in the recitation of these parts on the stage, and as generally read, the meaning is given to Lady Macbeth’s simple words; and Macbeth is made perfectly innocently to answer without showing in his look any “strange matter.” But the king is coming close on his heels; there is no time to arrange details; and Macbeth goes away to receive him, saying, “We will speak further.” The characters, as exhibited in the next scenes, have been already sufficiently discussed. He shows his superstitions, his visions, his poetry, and his hesitations; she, with the stern determination of a woman who has screwed her courage to the sticking-place, is agitated by no visions, but, feeling the necessity of immediate action, she occupies herself in the arrangements of details, and thus dulls her conscience.
