Ray Russell - Incubus

Synopsis:
Galen, California is a small coastal town mostly known for its remarkable resemblance to 
any small New England town. Most of the women in Galen are beautiful (or at least striking), 
and the residents just go on about their normal lives. Then tragedy strikes, and a young 
woman is brutally raped and murdered. When this tragedy begins to repeat itself over and 
over, even the most outlandish explanation seems plausible. Throw in the handsome 
anthropologist turned supernatural investigator, his love interest (the beautiful local 
newspaper editor), a dedicated but baffled sheriff, a gruff but loveable town doctor, and 
a rich but mysterious family with a secret history and a big house on the hill, and 
you have all the makings for a perfect 70s horror novel. Oh, and mix liberally with 
sexual innuendo, masculine protectiveness of female virtue, and loads of dreams, 
hallucinations, and flashbacks to ancient torture practices.
