I turned around and fired blindly into the blackness. The flash from my rifle illuminated something in the trees, and I fired again. This time I heard a yelp of pain, distinctly animal, and—my eyes having adjusted to the darkness—I saw the glimmer of yellow eyes and teeth, and then whatever they were, they were gone. I focused every bit of my attention on sound, trying to tell if they were circling around to attack me from another angle, but all the noises died away suddenly.
