Our Lady of Darkness introduces San Francisco horror writer Franz Westen. While studying his beloved city through binoculars from his apartment window, he is astonished to see a mysterious figure waving at him from a hilltop two miles away. He walks to Corona Heights and looks back at his building, to discover the figure waving at him from his apartment window—and to find himself caught in a century-spanning curse that may have destroyed Clark Ashton Smith and Jack London.
