Cover-up and Suspicion
Macbeth begins constructing his cover story. When asked what happened, Lennox explains that the guards' "hands and faces were all covered with blood" along with their daggers. This makes them look guilty, exactly as Lady Macbeth planned.
In a surprising move, Macbeth reveals he killed the guards in a supposed fit of rage over Duncan's death. When Macduff asks why, Macbeth delivers an elaborate, poetic speech about finding Duncan's body: "His silver skin laced with his golden blood, and his gashed stabs looked like a breach in nature." His excessive language suggests he's trying too hard to seem innocent.
Lady Macbeth suddenly faints, creating a distraction at the precise moment Macduff begins to question Macbeth's actions. This convenient timing suggests her "fainting spell" might be another calculated performance.
Think critically: Is Lady Macbeth's fainting real or fake? It happens right when Macbeth is being questioned about killing the guards, providing a convenient distraction.
Meanwhile, Malcolm and Donalbain, the king's sons, decide to flee separately – Malcolm to England and Donalbain to Ireland. They wisely recognize the danger, with Donalbain noting, "Where we are, there's daggers in men's smiles." Their escape, however, makes them look suspicious, as Macduff later points out.
