Thestorm outside the old mansion’s walls raged furiously. The guests had all arrived by eight o’clock that evening. Emily felt a chill despite the grand fireplace’s warmth. Whispers echoed through the hallways as shadows grew longer. The butler’s hands trembled as he poured the evening tea. No one dared speak of the murder they all feared. The chandelier above flickered, casting eerie shapes on walls. A sudden crash from the library made every head turn. Emily’s heart pounded as she recognized the unmistakable sound. The host had warned them all to stay together that night.
