The storm raged violently as darkness swallowed the village whole. Eleanor clutched her shawl tighter against the bitter night wind. A single flickering lantern dangled from her trembling fingertips. Shadows stretched long and monstrous on bloodstained cobblestones below. Her breath hitched sharply as a guttural scream tore through the air. Footsteps splashed erratically through the muddy, unwelcoming streets. Eleanor’s pulse thundered in her ears like a drumroll of dread. The gas lamp above sputtered, extinguishing with a hollow sigh. Something wet and warm dripped down her neck without warning. Silence followed, thick, heavy, and heavier than any grave’s embrace.
