Three figures materialize on a blasted heath and speak a soldier's secret ambition aloud, and from that moment the world tilts toward blood. Shakespeare's shortest and most ferocious tragedy, likely written in 1606, compresses tyranny into a single headlong plunge: the brave thane who murders his king, seizes the crown, and discovers that power held through violence must be sustained through more violence until nothing remains to protect. Lady Macbeth's sleepwalking, her hands that will not come clean, is the play's terrible emblem of conscience surviving the will that tried to kill it. Scotland bleeds, the natural order revolts, and the verse itself grows feverish. No play has ever shown so nakedly how ambition becomes its own punishment.
