Ever since its magazine appearance ten years ago, Fritz Leiber's "Conjure Wife" has been esteemed as the definitive novelistic treatment of witchcraft in the modern world. A precisely balanced blend of fantasy and science fiction, of psychological novel and suspense melodrama, it stands on a plane with Leiber's own "Gather, Darkness!" or "Destiny Times Three"—which means all of the impact and excitement of the best pulp story-telling, with a literacy and subtlety advanced well beyond most of Mr. Leiber's colleagues.
