This was an interesting read. I was first keyed into Manly Wade Wellman after reading that he was a friend, and somewhat of a mentor, to Karl Edward Wagner - an author who is quickly rising into my top teir of favorites. Furthermore, Wellman's heyday of writing began during the pulp era of the 1930s, and this happens to be a period which I've always been drawn to: I adore authors such as Lovecraft, Blackwood, Onions and more.
Now having said that - this particular novella was somewhat middling. I actually enjoyed the setup and the story, and there can be little doubt that Wellman was well acquainted with the paranormal scholarship of the way: he extensively quotes Summers, for instance. And no one an doubt that he was incredibly well versed in the folklore and history of the Appalachia and the South (of note: Wellman was a Southron nationalist at heart, though his Lost Cause leanings don't come out in this story at all). I found myself learning some things, and also hearing about books that I would actually rather like to look into! The story is also a quick read, with fast and exciting pacing.
However, The Hairy Ones Shall Dance, does have its weaknesses. The characters are rather flat and one or two dimensional. Although the ending is set up as a mystery and a twist, there weren't all that many clues given to the reader to figure it out on their own. Also, certain characters exist solely to pontificate and provide exposition (actually, Judge Pursuivant, is one of these - though that doesn't stop him from being one of the most engaging and fun characters in the story!). Which is a longwinded way ot saying that the writign can occassionally be clunky. Part of this may be because this is one of Wellman's earlier works and he was still finding his voice - I have recently purchased a collection of his shortstories so I suppose I will soon find out. And another part may be the venue and the time of publication - though I've read a fair bit of that era and am acquainted with it's stlyistic tropes and the like.
All in all, I'd recommend The Hairy Ones Shall Dance for those looking for a fun, snappy horror story.
