If a ghost is seen, what is it interests me less than than what sees it? Thus Algernon Blackwood describes his fascination with human beings ability to sense invisible powers and stirrings in the universe, a fascination he developed most famously in his stories about mystical, ineffable encounters with nature. This collection, selected by renowned scholar of the supernatural, E. F. Bleiler, is an excellent sample of Blackwoods work, including 12 of his best ghost stories and a crime story as well. Blackwood is acknowledged today as the author who made the ghost story into a respectable literary form.
