Kutzer further believes that however much Potter wished to provide an example of moral behaviour for the reader in the last pages of the tale (the mice "paying" for their misdeeds), her sense of fairness and the subtext of British class unrest actually account for the tale's ending. Social authority (the policeman doll) and domestic authority (the governess) are both ineffective against the desires of the mice: one illustration depicts the animals simply evading the policeman doll to prowl outside the house and another illustration depicts the mice instructing their children about the dangers of the governess's mousetrap. Their repentance is merely show: Tom Thumb pays for his destruction with a useless crooked sixpence found under the rug and Hunca Munca cleans a house that is tidy to begin with. Their respectful show of repentance covers up their continuing rebellion against middle class authority. Although Potter approves of the domestic and social rebellion of the mice and their desire for a comfortable house of their own, she disapproves of the emptiness and sterility of the dolls' lives in the doll's house yet understands the attractions of a comfortable life made possible in part by the labour of servants.
