I can't stop thinking about what Caroline said to Minna about death. It isn't an infection, she said. She might be right. Then again, we've nested in the walls like bacteria. We've taken over the house, its insulation and its plumbing - we've made it our own. Or maybe it's life that's the infection: a feverish dream, a hallucination of feelings. Death is purification, a cleaning, a cure.
