The Edge of Running Water deals with the adventures of a young psychologist in a remote Maine farm house; with the death of a woman and the disappearance of an inventor. Against a normal enough background, events take on the shape of terror, with a tinge of the unknown - hints of things beyond the borderland of the natural, including the strange researches into survival after death by a half-mad electro-physicist. Set against these, a tender love story adds an unexpected poignancy and charm.
