Summary: Act 2, scene 1

Banquo and his son Fleance walk in the torch-lit hall of Macbeth’s castle. Fleance says that it is after midnight, and his father responds that although he is tired, he wishes to stay awake because his sleep has lately inspired “cursed thoughts” (2.1.8). Macbeth enters, and Banquo is surprised to see him still up. Banquo says that the king is asleep and mentions that he had a dream about the “three weird sisters.” When Banquo suggests that the witches have revealed “some truth” to Macbeth, Macbeth claims that he has not thought of them at all since their encounter in the woods (2.1.19–20). He and Banquo agree to discuss the witches’ prophecies at a later time.

Banquo and Fleance leave, and suddenly, in the darkened hall, Macbeth has a vision of a dagger floating in the air before him, its handle pointing toward his hand and its tip aiming him toward Duncan. Macbeth tries to grasp the weapon and fails. He wonders whether what he sees is real or a “dagger of the mind, a false creation / Proceeding from the heat-oppressed brain” (2.1.38–39). Continuing to gaze upon the dagger, he thinks he sees blood on the blade, then abruptly decides that the vision is just a manifestation of his unease over killing Duncan. The night around him seems thick with horror and witchcraft, but Macbeth stiffens and resolves to do his bloody work. A bell tolls—Lady Macbeth’s signal that the chamberlains are asleep—and Macbeth strides toward Duncan’s chamber.

Summary: Act 2, scene 2

Will all great Neptune’s ocean wash this blood
Clean from my hand? No, this my hand will rather 
The multitudinous seas incarnadine, 
Making the green one red.

As Macbeth leaves the hall, Lady Macbeth enters, remarking on her boldness. She imagines that Macbeth is killing the king even as she speaks. Hearing Macbeth cry out, she worries that the chamberlains have awakened. She says that she cannot understand how Macbeth could fail—she had prepared the daggers for the chamberlains herself. She asserts that she would have killed the king herself then and there, “[h]ad he not resembled / [her] father as he slept” (2.2.12–13). Macbeth emerges, his hands covered in blood, and says that the deed is done. Badly shaken, he remarks that he heard the chamberlains awake and say their prayers before going back to sleep. When they said “amen,” he tried to say it with them but found that the word stuck in his throat. He adds that as he killed the king, he thought he heard a voice cry out: “Sleep no more, / Macbeth does murder sleep” (2.2.33–34).

Lady Macbeth at first tries to steady her husband, but she becomes angry when she notices that he has forgotten to leave the daggers with the sleeping chamberlains so as to frame them for Duncan’s murder. He refuses to go back into the room, so she takes the daggers into the room herself, saying that she would be ashamed to be as cowardly as Macbeth. As she leaves, Macbeth hears a mysterious knocking. The portentous sound frightens him, and he asks desperately, “Will all great Neptune’s ocean wash this blood / Clean from my hand?” (2.2.58–59). As Lady Macbeth reenters the hall, the knocking comes again, and then a third time. She leads her husband back to the bedchamber, where he can wash off the blood. “A little water clears us of this deed,” she tells him. “How easy it is then!” (2.2.65–66).

Act 2, scenes 3–4

Summary: Act 2, scene 3

A porter stumbles through the hallway to answer the knocking, grumbling comically about the noise and mocking whoever is on the other side of the door. He compares himself to a porter at the gates of hell and asks, “Who’s there, i’ th’ name of Beelzebub?” (2.3.3). Macduff and Lennox enter, and Macduff complains about the porter’s slow response to his knock. The porter says that he was up late carousing and rambles on humorously about the effects of alcohol, which he says provokes red noses, sleepiness, and urination. He adds that drink also “provokes and unprovokes” lechery—it inclines one to be lustful but takes away the ability to have sex (2.3.27). Macbeth enters, and Macduff asks him if the king is awake, saying that Duncan asked to see him early that morning. In short, clipped sentences, Macbeth says that Duncan is still asleep. He offers to take Macduff to the king. As Macduff enters the king’s chamber, Lennox describes the storms that raged the previous night, asserting that he cannot remember anything like it in all his years. With a cry of “O horror, horror, horror!” Macduff comes running from the room, shouting that the king has been murdered (2.3.59). Macbeth and Lennox rush in to look, while Lady Macbeth appears and expresses her horror that such a deed could be done under her roof. General chaos ensues as the other nobles and their servants come streaming in. As Macbeth and Lennox emerge from the bedroom, Malcolm and Donalbain arrive on the scene. They are told that their father has been killed, most likely by his chamberlains, who were found with bloody daggers. Macbeth declares that in his rage he has killed the chamberlains.

Macduff seems suspicious of these new deaths, which Macbeth explains by saying that his fury at Duncan’s death was so powerful that he could not restrain himself. Lady Macbeth suddenly faints, and both Macduff and Banquo call for someone to attend to her. Malcolm and Donalbain whisper to each other that they are not safe, since whoever killed their father will probably try to kill them next. Lady Macbeth is taken away, while Banquo and Macbeth rally the lords to meet and discuss the murder. Duncan’s sons resolve to flee the court. Malcolm declares that he will go south to England, and Donalbain will hasten to Ireland.

Summary: Act 2, scene 4

Ross, a thane, walks outside the castle with an old man. They discuss the strange and ominous happenings of the past few days: it is daytime, but dark outside; last Tuesday, an owl killed a falcon; and Duncan’s beautiful, well-trained horses behaved wildly and ate one another. Macduff emerges from the castle and tells Ross that Macbeth has been made king by the other lords, and that he now rides to Scone to be crowned. Macduff adds that the chamberlains seem the most likely murderers, and that they may have been paid off by someone to kill Duncan. Suspicion has now fallen on the two princes, Malcolm and Donalbain, because they have fled the scene. Macduff returns to his home at Fife, and Ross departs for Scone to see the new king’s coronation.
