Mrs Lyons

Mrs Lyons exploits Mrs Johnstone's financial desperation, proposing that she hand over one unborn twin to be raised as a Lyons child. She then coerces Mrs Johnstone into swearing secrecy on a Bible, using her employee's religious faith and powerlessness. The arrangement is framed as generosity, but Russell makes clear it is a calculated transaction driven entirely by Mrs Lyons's self-interest.

Her most chilling line is: "Did you know that if a mother gives away a child, and then the two children meet and find out they're twins, they'll both die immediately?" She invents this curse to terrorise Mrs Johnstone into silence. The dramatic irony Russell builds is devastating — the fabricated superstition ultimately becomes the moral framework for the entire play's tragedy, haunting Mrs Lyons as much as its intended victim.

Mrs Lyons fires Mrs Johnstone as soon as the handover is complete, because her continued presence in the house risks exposing the secret. The dismissal confirms that her earlier warmth toward Mrs Johnstone was purely instrumental — once she has served her purpose, she is discarded. It is one of Russell's clearest signals that Mrs Lyons's apparent generosity was always a mask for calculated self-interest.

Mrs Lyons pressures Mr Lyons into relocating the family when she discovers that Edward and Mickey have become close friends, fearing their bond will expose the twins' true connection. The move is a drastic escalation of her paranoia, uprooting innocent people — including Edward — solely to sustain her lie. Russell uses it to show how her obsessive need for control has spread far beyond the original deception.

Russell presents her as both. Her longing for a child is genuine, and her childlessness makes her sympathetic at the outset. However, her methods — exploitation, coercion, dismissal, a fabricated curse, and finally a knife attack on Mrs Johnstone — are calculated cruelties that poison every relationship she forms. Russell suggests her privilege enables each stage of the deception, making her moral collapse inseparable from her social position.

Mrs Lyons raises Edward with material comfort but surrounds him with emotional suffocation, whereas Mrs Johnstone, despite poverty, offers her children warmth and freedom. Mrs Lyons's love is possessive and paranoid — she isolates Edward and relocates the family to sever his bond with Mickey. Russell's irony is that her obsessive possessiveness guarantees the alienation she most fears, while Mrs Johnstone's open affection nurtures genuine connection.

By the play's climax Mrs Lyons has deteriorated into barely coherent paranoia. Her psychological unravelling reaches its most visible moment when she confronts Mrs Johnstone with a knife — the respectable, poised employer of the opening scenes has completely disintegrated. Russell draws a direct causative line from the original act of taking Edward to every subsequent act of self-destruction, showing that her single calculated cruelty corrupts her entire life.

She fabricates a folk curse — that twins separated at birth will die immediately if they discover each other — purely to intimidate Mrs Johnstone into permanent silence. The invented superstition is a manipulation that exploits Mrs Johnstone's vulnerability and faith. Russell uses it as dramatic irony: the curse Mrs Lyons cynically manufactures is the very framework the Narrator uses to structure the play's tragedy, returning to Mrs Lyons as a form of judgment on her own guilt.
