The Workhouse Matron

The Workhouse Matron
Authority through fear
Miss Frost uses the cane, insults children, and confines them in a dark punishment room. Sunday’s refusal to cry intensifies the matron’s determination to break her.
Discipline disguises cruelty
The matron presents her methods as order, yet she ignores rules and the children’s safety. Her power depends on the institution’s weak oversight and the inmates’ fear of speaking.
Jealousy and Complicity

Jealousy and Complicity
Protection withheld
Miss Frost sees Pinnegar’s interest in Cissie and later Sunday but does not protect them. Instead, she helps direct girls to his office and punishes those who resist his authority.
Personal desire beneath obedience
She is also infatuated with Pinnegar and resents the girls who attract his attention. Her conduct blends institutional power with jealousy and self-interest.
Humiliation After Dismissal

Humiliation After Dismissal
The household loses power
After Pinnegar is dismissed, Miss Frost’s workhouse position also ends. Pinnegar rejects her when she suggests joining him, calling her old and unwanted.
A grievance deepens
The rejection and loss of status intensify Miss Frost’s bitterness. She becomes increasingly isolated, while Sunday and the other former inmates move into lives beyond her control.
Crimes Behind the Threats

Crimes Behind the Threats
Revenge reaches outward
Miss Frost kills Daisy and later Pinnegar, then targets Sunday. Her actions reveal that the supposed random attacks on the Lodge were part of a wider campaign of violence.
The old matron’s mask collapses
When Sunday sees her again, Miss Frost is unkempt and mentally unstable. The woman who once controlled children through rules has become a fugitive who uses confinement and terror herself.
A Last Attempt at Control

A Last Attempt at Control
Abduction recreates the cellar
Miss Frost binds Sunday in a cellar and calls it a punishment room. She intends to force Sunday to cry before killing her, repeating the cruelty she once inflicted under institutional authority.
Arrest ends the cycle
Tom and the constables interrupt the attack and arrest Miss Frost. Her confinement at Hatter’s Hall prevents further violence, although it cannot restore the lives she destroyed.
