In this lyrical, frightening passage, several of the story’s central themes come together. In order to protect her family, Marn has to turn her passionate sex with Billy into something murderous rather than life-giving, filled with death rather than being (as Evelina might say) “deathless.” Yet even more than lust and desire, what bolsters Marn through this act of terrifying bravery is her knowledge of land ownership. The only thing Marn feels she needs to build life after Billy is the “land deed in my name,” proof that even if property is a form of artificial “mastery” (in Judge Coutts’s words), it is also the single most essential key to power and safety.
