Black Spirits and White: A Book of Ghost Stories - Ralph Adams Cram

A collection of six ghostly tales by Ralph Adams Cram, ranging from the demonic to the deeply sad. Gruesome apparitions, oppressive atmosphere, and throughout it all, a profound appreciation for the haunting beauty of Europe through the eyes of an American architect. Includes The Dead Valley, a story singled out as "memorably potent" by H.P. Lovecraft.
Black spirits and white - Red spirits and gray - Mingle, mingle, mingle - Ye that mingle may. (Summary by Andrew Gaunce, with excerpt from Shakespeare's Macbeth)
