Audible.com has made available a two and a half hour long, well, "audio movie," I suppose you could call it. The Dancer in the Dark was written by the late Thomas E. Fuller, a hell of a good writer, and is performed by the Atlanta Radio Theatre Company.
If you discovered and liked H.P. Lovecraft, this is a treat. Fuller moves the spookiness south, to the fictional Blankenship, Georgia, and the plot involves a retired Professor of Archaeology from Miskatonic University (!) who undertakes to help his nephew solve the riddle of some ancient Native American mounds.
And then the riddle turns deadly. Shock and humor and intense local and period detail make this one a keeper. If you'd like to check it out, you can find it right here: THE DANCER IN THE DARK.
