Beware Jerusalem!

Fall. 1969. A remote mansion high atop a cliff above the Mississippi River south of St. Louis. Mathew Hoehn, a recently invalided-home veteran, learns he is the last heir of a wealthy great aunt. She is the matriarch of a family which has lived on the property since the 1830s. And since the Civil War they have lived in fear of-and died from-a curse and the terrible wrath that has been unleashed.
