Its gray-green skin is pulled taut over its spine and rib cage, the bones close to breaking through. Its head dangles perilously on a scrawny neck, black tongue unfurling over a row of blade-sharp teeth. Its tongue lolls on the ground as the creature crawls toward me on all fours, hissing and groaning. Its eyes are not eyes at all. They are twin clusters of flies gathered on its gaunt face.
