Something goes drastically wrong at a séance, and suddenly Alan's wife Janice experiences a major personality change. These are signs that her husband just can't ignore: the strange new mark on her hand, the naked wanderings in moonlight, the blood stains on her clothes, not to mention the strange company she now keeps. Alan turns to an ex-Roman Catholic priest, Ruane, a man drained of self-respect, a drunkard, a reject--but the only one who seems to understand what's going on--and how to deal with it. Together they must confront the Evil from Beyond. A top-ranked horror novel by a master of the genre, now republished for the first time in almost four decades.
