The Dunwich Horror

Dr. Henry Armitage, Sandra Dee and another girl who wasn’t in the book visit the library of the Miskatonic University where they are studying, and find a mysterious young man named Wilbur Whateley trying to borrow the Necronomicon (to non-HPL fans : a book containing ancient rites to bring alien gods to our planet), and as it is a public library they let him. Sandra Dee offers to drive the moustachioed warlock back to his home in Dunwich, where he drugs her and makes her stay to be a part in his evil ceremonies.
