Therain hammered against the window panes steadily. Shadows danced menacingly across the dimly lit room. A faint scent of lavender lingered in the air. Eleanor adjusted her emerald necklace with trembling fingers. "Who could have possibly wanted him dead?" whispered the voice behind her. The fireplace crackled, casting eerie shadows on the walls. A sudden gust of wind made the candles flicker violently. The grandfather clock struck midnight, echoing through the hall. Eleanor's heart pounded in her chest as she turned around. A figure stood in the doorway, silhouetted against the stormy night. The guests had gathered for what was supposed to be a pleasant evening. Little did they know, tragedy would strike before dawn arrived.
