The heavy rain fell steadily upon the dark cobblestone streets where long shadows danced silently beneath the pale moonlight tonight. The wet pavement reflected the dim gaslight while distant church bells tolled twelve mournful notes across the sleeping cold neighborhood. The weary detective adjusted his dark wool coat and stared toward the shaded open window where crimson stains waited outside. His leather gloves trembled slightly as he knelt down to examine the small silver device carefully placed near the door. Thick crimson liquid pooled around the fallen antique furniture while silence filled every corner of the grand dining room tonight. No footprints remained upon the wooden floorboards as detectives searched every hidden corner for any valuable clues that might help.
