This a good thread idea as I hear that question by the bucket load.
Something that has bugged me for quite some time, is a TV show that i think I watched in the early 90’s on late night television which is based in American book store and had three main characters, two guys and one girl, who work there deal with the paranormal, and get their information from a individual book on the subject.
Are you sure you’re not thinking of Friday The 13th The Series? Which had nothing to do with maniacs in hockey masks killing horny teenagers at summer camp.
