Plot Summary
Act 2, Scene 3 of Macbeth opens in the aftermath of King Duncan's murder with a jarring shift in tone. A drunken Porter stumbles to the gate of Macbeth's castle, responding to persistent knocking. He imagines himself as the gatekeeper of Hell, admitting a parade of sinners: a greedy farmer who hanged himself, a treacherous equivocator, and a thieving English tailor. His darkly comic monologue provides a brief moment of levity in the play's most intense sequence, while the Hell imagery ironically reflects the moral reality of what has just occurred within the castle walls.
The Porter finally opens the gate to admit Macduff and Lennox, who have arrived at Duncan's request for an early morning audience. The Porter and Macduff exchange bawdy jokes about the effects of alcohol before Macbeth enters and greets his guests. While Macduff goes to wake the king, Lennox describes the wild and unnatural disturbances of the previous night—violent storms, strange screams, and an earth that seemed to shake with fever. Macbeth responds with studied understatement: "'Twas a rough night."
Macduff returns in horror, crying "O horror, horror, horror!" He announces that Duncan has been murdered, calling it a sacrilegious act that has broken open "The Lord's anointed temple." The alarm bell rings, and the castle's inhabitants rush to the scene. Lady Macbeth appears and feigns shock, while Banquo reacts with genuine grief. Macbeth delivers an eloquent speech about the meaninglessness of life now that Duncan is gone, declaring that "the wine of life is drawn" and only the dregs remain.
When Lennox reports that the king's guards appeared to be the murderers—their hands and faces smeared with blood, their daggers left unwiped on their pillows—Macbeth reveals that he has already killed them in a fit of rage. This impulsive act, not part of the original plan, draws suspicion from Macduff, who pointedly asks, "Wherefore did you so?" Macbeth justifies himself by claiming his violent love for Duncan overwhelmed his reason. At this tense moment, Lady Macbeth conveniently faints, diverting attention away from her husband.
The scene closes with a private exchange between Duncan's sons, Malcolm and Donalbain, who recognize the danger of their position. Sensing that "there's daggers in men's smiles," they resolve to flee—Malcolm to England, Donalbain to Ireland—rather than risk becoming the next victims. Their flight will later be used against them as evidence of guilt, further securing Macbeth's path to the throne.
