In a career that spanned more than six decades, Arthur Machen produced some of the most evocative weird fiction in all literary history. Written with impeccably millifluous prose, infused with a powerful mystical vision, and imbued with a wonder and terror that their author felt with every fibre of his being, his novels and tales will survive when works of far greater technical accomplishment fall by the wayside. Flawed as some of them are by certain crotchets --- especially a furious hostility to science and secularism --- that disfigure Machen's own philosophy, they are nonetheless as effective as they are because they echo the sincere beliefs of their author, whose eternal quest to preserve the mystery of the universe in an age of materialism is one to which we can all respond.

The contents list is long, so I'll briefly give you my favorites:
"The Islington Mystery": A man who sees himself much smarter than Dr. Crippen can't stand the suspense of the wait until his capture;
"The Lost Club" : in which two men accidentally come upon a gentleman's club where strange goings-on occur
"The Bright Boy": a story told by the tutor of a young boy in a very strange household
"Out of the Picture": this is a good one. A maniac is terrorizing the streets of London and it seems that he's not real.
"Change" - a picnic in some caves uncovers the existence of foul goings-on;
and my favorite, "The Dover Road," probably the best in the book, about a man who goes along to an old house with others and disappears.
I love Machen's stories about the "little people," and how he weaves in strands dealing with Celtic myth. It's very easy to see how Lovecraft was influenced by this author. Start with Volume I, though; it's by far the best of this series. (
