Today is Halloween, a day for tricking or treating and dressing up, the annual celebration of all things scary. They day is believed to have pagan roots, originating from the Celtic harvest festival Samhain.
Even though Halloween will be over at midnight, you can still indulge your taste for the scary (if you have a taste for the scary). A couple of options at SPL: The Oxford Book of Gothic Tales or Neil Gaiman's The Ocean at the End of the Lane. You could also search the catalog using the subject "horror fiction." If you're interested in scary movies, I suggest Dutch director George Sluizer's blood-curdling masterpiece The Vanishing.
