"And it harm none, do as you will," so says the ancient Wiccan Rede. Those who do not heed its words will learn the power of the Law of Three. Annie, Kate, and Cooper uncover what looks like a crime. When they look more closely, it is not. Knowing the Law of Three -- that harm comes back to haunt -- can they still help a friend in need without paying for it themselves?
