Both of these were popular novels long before my time, but when I was in college in the 1990s, I was quite taken with the film version of The Exorcist, which to me is one of the scariest movies ever made. Since William Peter Blatty’s novel of the same name was first published in 1971, there have been no end of books and movies about exorcism of varying quality; such films are practically their own industry at this point. People sure enjoy reading books and watching scary films about demonic possession.

Ray Russell’s The Case Against Satan, originally published in 1962, is an excellent, tightly paced and disturbing read about a case of possession and exorcism involving a young girl. It predates Blatty’s novel by nine years, so it is probably the first novel of its kind. It’s a very different read from the Exorcist, told with more attention to psychology and spiritual matters. Russell was a fine writer of Gothic tales, and I highly recommend his short stories. There are a couple of good books that collect most of them, including the very creepy Sardonicus.

The Exorcist reads more like a page turning thriller than Russell’s work. The story is more over the top, which fans of the film will recognize. If you like this genre of horror movie, I think you owe it to yourself to read this book and see where it started. Russell’s less well-known book is also a must read. Both novels do a great job of bringing this ritual to life; even if you aren’t Catholic, or don’t believe that possession is something that exists, I still think the books are well worth reading for their treatment of the topic. You can read them on the level of enjoying a good scare, but I feel that there is more here in the way Russell and Blatty discuss the nature of evil, the possibility that ‘the adversary’ exists. Many of us still believe in a spiritual life, and here we also see the belief in the dark side of that world. Both of these books stayed with me long after I read them–I found that their reputations are well-earned.
