The rain tapped softly on the old manor’s roof, a steady rhythm in the dead of night. Detective Clara Vale stepped inside, her boots leaving wet prints on the polished marble floor. The body lay sprawled by the fireplace, one hand clutching a torn letter stained with blood. A single candle flickered nearby, casting long shadows that danced across the victim’s pale face. Clara knelt beside him, noticing the faint scent of almonds lingering in the cold, still air. The butler stood silently in the doorway, his expression unreadable beneath the dim glow of the chandelier. Outside, thunder rumbled like a distant warning, echoing through the empty halls of the forsaken estate. Clara’s fingers brushed the victim’s coat pocket, finding a small silver key with intricate engravings. She turned it over, wondering what secrets it might unlock in this house of whispers. The clock struck midnight, its chime slicing through the silence like a blade through flesh.
