Macbett—Lady Duncan
The KillerMacbett—Lady Duncan is a political and intimate alliance whose promised marriage never joins the two people it appears to unite. Lady Duncan helps draw Macbett toward power, and the pair enlist Banco in a conspiracy against Duncan; but a sorceress takes Lady Duncan’s face and place, leaving Macbett to celebrate a counterfeit union while the real woman remains imprisoned. When she returns, she names him a murderer and usurper, and the relationship’s trajectory from complicity to rupture becomes part of the play’s unmasking of power as performance.
Attraction and the Language of Ambition
Lady Duncan presents Macbett with the dagger as an instrument of their shared rise. She invites him to take it, links his desire for her to an ambition she says is emerging, and imagines him replacing Duncan at her side. The blade’s future bloodstain is to be both a souvenir of success and an incentive to further achievement. Her appeal fuses intimacy with political violence: desire is not separate from ambition but one of the means by which she urges it into action. Macbett hesitates, and Lady Duncan presses him to act boldly rather than remain in doubt.
Their later engagement seems to confirm that this appeal has become a personal bond as well as a political project. Macbett calls Lady Duncan vivacious, energetic, and intellectual, and says she has profound views about humanity’s future without being a Utopian dreamer. This description comes from Macbett himself, in conversation with Banco, and presents Lady Duncan as a person whose force of mind he admires, not merely as the object of his desire. Banco responds that people are difficult to know until they open their hearts, while noticing the dagger at Macbett’s belt. Macbett identifies it as Lady Duncan’s gift, making the weapon a visible reminder that his courtship and his pursuit of power have become entwined.
Alliance Against Duncan
The relationship also takes shape through shared political intervention. When Banco protests that Duncan has failed to give him the promised title or lands, Macbett says that he and Lady Duncan have both tried to secure a position for him as the king’s adviser. He claims she is upset by Duncan’s thoughtlessness and has already spoken to the Archduke on Banco’s behalf. When these efforts fail, Macbett proposes using stronger arguments. The couple’s apparent solicitude for Banco thus becomes a route toward a broader challenge to Duncan’s authority.
Macbett eventually makes their conspiracy explicit to Banco. He proposes dividing the kingdom, with himself taking the throne and Banco serving as chamberlain; then he clarifies that Banco would be third in the arrangement, because Lady Duncan is also part of the conspiracy and indispensable to it. The alliance is therefore not simply a private compact between two would-be rulers. It is a planned distribution of power among three participants, with Lady Duncan included as an essential political actor. When Banco accepts the design, all three cross their daggers and swear to kill Duncan. Lady Duncan’s declaration of commitment to the death gives their agreement the form of a shared vow, while the daggers turn the earlier gift into part of a collective pledge of violence.
The Marriage They Plan
After Macbett’s rise, the couple appear to move from conspiracy to public recognition. As cheers for Macbett and his bride grow louder, Lady Duncan says she is tired after her exertions and plans to rest in her apartments. Macbett tells her he will collect her at ten the next morning for the marriage ceremony, followed by his coronation at midday and a wedding feast at five. Lady Duncan offers her hand to be kissed and takes leave of him until the following day. The sequence makes their union seem imminent and formally endorsed: marriage, coronation, and banquet are arranged as successive stages of the same public celebration.
That expected future makes the later revelation more consequential. Macbett speaks as though he has defeated his wife’s prediction and uncovered her arrangements, while the woman addressed as his wife says she can explain but not in public. The exchange shows him asserting control over a partner he believes he understands. Yet the apparent intimacy and confidence are unstable: the marriage he celebrates has been made possible by an impersonation, not by the real Lady Duncan’s consent or presence.
Impersonation and Rupture
At the banquet, the real Lady Duncan returns and explains the substitution. The guests had seen Macbett marry a sorceress who had taken her face, voice, and body; the impostor had thrown her into the palace dungeons and chained her there. Lady Duncan says her chains have just fallen and the bolts drawn back as if by magic. Her account separates the political bride from the woman whose identity she borrowed: Macbett’s apparent wife is not the Lady Duncan who helped form the conspiracy.
Lady Duncan rejects any continuing bond with Macbett. She says she wants nothing to do with him and denies being his accomplice, then charges him with murdering his master and friend and calls him a usurper and impostor. The accusation reverses the language of their earlier alliance. The woman who had urged him to replace Duncan and had sworn herself into the conspiracy now refuses the identity of partner that Macbett’s marriage ceremony seemed to secure. His new status cannot make their relationship real; the return of the person whose likeness was appropriated exposes the wedding as a political spectacle built on her captivity.
Significance of the Relationship
Their relationship moves through overlapping forms of intimacy, political collaboration, and deception. Lady Duncan’s dagger turns desire into an appeal for action; the conspiracy makes her an indispensable participant rather than a silent consort; and the scheduled ceremony promises to give their alliance a public, dynastic form. Yet the counterfeit marriage breaks that apparent progression. The real Lady Duncan’s return reveals that Macbett’s possession of a title, a bride, and the symbols of sovereignty does not amount to the consent or loyalty he claims.
The rupture also makes the couple’s earlier language of shared purpose look precarious. Lady Duncan had offered Macbett a place beside her in power and helped imagine the overthrow of Duncan, but the play does not present their eventual union as a secure reward for that conspiracy. Instead, an impostor occupies her place, and the real woman returns only to condemn Macbett. The alliance thus ends not in the promised partnership but in exposure: the marriage ceremony has joined Macbett to a false likeness, while the person he had treated as his political and intended marital partner repudiates him in public.
