Michel Foucault has suggested that since the 18th century, we have read the history of sexuality according to the "repressive hypothesis".
This hypothesis suggests that since the rise of capitalism, sex outside of marriage became frowned upon, and subsequently, repressed by society.
Whereas, in previous centuries, such as the Renaissance, sexuality was approached with a more light-hearted attitude.
However, Foucault suggests that due to this desire to suppress sexuality in society, discourse on the subject began to increase.
It could be argued, Abbott uses her novel as a tool to encourage the discussion of female sexuality and convey the stigma still associated with female sexuality in today's society. Thus, the novel could be examined from a feminist standpoint, as a criticism of the sexism and double standards that remain tied to women.
As Foucault suggests, perhaps the concept of "sexuality", has been socially constructed as a way of regulating society, enforcing terms and rules onto a subject that was once viewed with little concern.
The concept that the sexuality and bodies of the girls has resulted in an outbreak of a "fever" or illness, in which the police control need to get involved, portrays an element of criminality to the case. Thus, arguably the sexual liberation and bodies of women become depicted as "criminal" in the eyes of society.
It is this element of "criminality" attached to female sexuality and the psychology of women, that Foucault suggested as being a means to regulate and control others.
Therefore, Abbott could be suggesting that women are still controlled by the patriarchy.
