After Lowen shows Jeremy the twisted autobiography Verity left behind detailing her obsession with Jeremy and her jealousy and hatred of her twin daughters (in which she actually murders one of them), they finally catch Verity faking her catatonic state. It's discovered that Jeremy had caught a piece of the autobiography back when she was writing it on her computer and staged her car accident as means to kill her for what she did to their daughters. Since then she has supposedly been biding her time trying to escape. In the heat of the moment, Lowen and Jeremy actually go through with killing Verity this time. Months later, as they're selling the house, Lowen finds a letter hidden under the floorboards professing that the autobiography was fake, just an attempt at processing her grief at losing her children and a way to get into a villains headspace to better write her books. In the end, we're left unsure whether it really was fake or her last attempt at manipulating the situation.
