Of course there is such a thing as female perversion and female crime, but it is rare. Two easy entry-points into this realm are the Papin sisters and closer to the Anglophone world, the Parker-Hulme friends. These cases provide access to the world of the female murderer and the black widow, the relationship between gender and crime and the concept of the folie à deux.
One of the most astonishing facts about the Papin sisters is the defense of their actions by the French intellectuals of their time.
“I’ve seen the photos of these two pretty girls, these servants who killed and battered their mistresses. I’ve seen the photos before and after. ‘Before’, their faces hovered like two docile flowers above their lace collars. They radiated clean living and appetizing honesty. A discreet curling iron had crimped their hair in a similar manner. And, even more reassuring than their waved hair, their collars and their air of being on a visit to the photographer, was their resemblance as sisters, the self-righteous resemblance that immediately brought blood ties and the natural roots of the family group to the fore. ‘After’, their faces glowed like a blaze. They had the bare necks of the future beheaded. Wrinkles everywhere, horrible wrinkles of fear and hatred, folds, holes in the flesh as if a clawed beast had roamed round and round on their faces. And those eyes, those same big, dark and bottomless eyes… And yet, they no longer looked alike. Each, in her own way, bore the memory of their common crime…” –“Le Mur” by Sartre
Motives of Paranoiac Crime: The Crime of the Papin Sisters, a paper by Jacques Lacan brought me to French intellectuals on the Papin sisters. Also to Nosubject.com, the Lacan wiki.
“Christine and Léa were genuine Siamese souls. Between them, the two sisters couldn’t even find the distance needed to wound each other…
“Christine must have gone through such torture before the desperate experience of crime tore her from her other self and allowed her, after the first hallucinatory fit in which she thought she saw her sister dead, to cry the words of blatant passion: ‘Yes, say yes!’” –Taken from “Motives of Paranoiac Crime: The Crime of the Papin Sisters“–Jacques Lacan
To conclude, from the diary of Pauline Parker:
“The day of the happy event” “I felt very excited last night and sort of night-before-Christmas but I did not have pleasant dreams…I feel very keyed up as though I were planning a surprise party. The happy event is to take place tomorrow afternoon. So the next time I write in this diary Mother will be dead.” –from Pauline Parker’s diary.
