“The fear Jackson refers to is not fear of lesbianism—or, at least, not only fear of lesbianism. It is the fear of what lesbianism represented to her, something that on one level she fervently desired even as she feared it: a life undefined by marriage, on her own terms. Constance and Merricat are indeed “two halves of the same person,” together forming one identity, just as a man and a woman are traditionally supposed to do in marriage. Not finding that wholeness in marriage, Jackson sought it elsewhere: first with Jeanne Beatty, and later with her friend Barbara Karmiller, also younger, who came back into her life shortly after she finished Castle. Indeed, the novel, in its final version, is not about “two women murdering a man.” It is about two women who metaphorically murder male society and its expectations for them by insisting on living separate from it, governed only by themselves.”
