The Dark of Mine tells about the demonic part of Izabella, her true possessed nature, her need to take lives. It is not a metaphor, not an allegory. Everything is literal. This is her ultimate pleasure, torturing and taking lives. "More pleasurable than sex" as she says. And this is what she hides best of all. No one should know about her true nature. Children, husbands, lovers, friends - nobody. This is her greatest secret.
