The grand ballroom glowed with candlelight softly flickering. A mysterious note slipped under the door of Eleanor’s chamber. Whispers filled the air, though no one dared speak aloud. Eleanor’s laughter echoed through the opulent, crowded hall. A single rose lay crushed beneath her favorite chair’s seat. The clock struck midnight, marking the hour of her last known sight. A shadow moved near the balcony where she had vanished. Someone had left a key in her pocket, hidden from view. The guests turned to stare as the door burst open violently. Her body lay cold and still, a stark contrast to the lively scene.
