Your home town must have had some interesting book stores, MB.... ;)
Believe it or not, I bought it up at one of the variety stores in my neighborhood. It was sitting on one of those four-sided metal paperback stands that you turn around to check out all the books. The title intrigued me, I started flipping through, it looked interesting, so I picked it up (no doubt with whatever magazines had DS articles in them that day ;)).
I dug it off of one of my bookshelves and here's the cover (in case anyone else is interested):

The publishing date says 1940, so it might still look the same for all we know.
The chapters that hooked me that day in the store have titles like: "World Champion Lady Vampire of All Time" (which is about the Countess Elizabeth Bathory, the central character in John Karlen's film Daughters of Darkness ;)), "Vampire 1932 from Brooklyn, N.Y.," "The Caged White Werewolf of the Saraban," "Magic Pentagrams and Circles," and "'Astral Body' on a Boat". All things DS-related. :D And there's even a chapter that makes reference to the I Ching, with all 64 hexagrams diagramed and the 49th hexagram circled. I'll defintely have to check that out again because, in part, the chapter says: "No. 49, the ko hexagram, is the one that got us into trouble."
