The heavy velvet curtains parted slowly to reveal the silent body lying twisted across the cold and polished marble floor. Lightning flashed against the tall windows, casting long, jagged shadows that danced over the victim’s pale and frozen face. A single drop of crimson blood stained the white rug while the grandfather clock chimed once in the hallway. Everyone stood frozen in the dim light, terrified by the sudden realization that a killer walked among them tonight.
