Here are two very creepy stories that I recently re-read. They are, I think, appropriate reading for Halloween:
The first is "The Lottery" by Shirley Jackson. It was first published in 1948 in The New Yorker magazine. The ending shocked readers and caused many to angrily cancel their subscription. Jim Freund, the host of Hour of the Wolf, a weekly sci-fi/horror/fantasy talk show on WBAI in New York, calls it the greatest horror story. (The story was anthologized in 50 Great Stories, edited by Milton Crane, Bantam Books, 1983, 46th printing.)
The second story is "The Fly" by George Langelaan. It was published in Playboy magazine in its June 1957 issue and was about a scientific experiment gone wrong. It later became the basis for the 1958 movie and the 1986 remake. (The story was anthologized in Stories of the Supernatural, edited by Betty M. Owen, Scholastic Book Service, 1967 and Pan Book of Horror Stories, edited by Herbert Van Thal, Pan Books, 1960.)
Happy Halloween, folks!
