The ballroom chandelier shattered, sending crystal shards across marble floors. Detective Mara pressed through the screaming crowd toward the body. Eleanor Whitfield lay crumpled beside the grand piano, blood pooling. Her champagne glass remained balanced impossibly upon the armrest nearby. The orchestra had stopped mid-waltz, frozen in collective disbelief together. Mara knelt, noting the faint smile still etched upon lips. It was not the expression of someone who expected death. Around the room, exactly fourteen witnesses pretended they had seen nothing. The scent of expensive perfume and something bitter clung together. Mara inhaled deeply, recognizing the almond beneath the jasmine perfume. Three motives already surfaced: money, jealousy, and old buried secrets. She looked toward the butler, whose eyes betrayed unsettling recognition. He nodded almost imperceptibly before vanishing through the kitchen doors. Eleanor's diamond necklace was missing, but her rings remained untouched. Someone wanted this to look like robbery, but planned carefully. The grandfather clock struck midnight as Mara photographed the scene. Fourteen suspects, one body, and a long night stretched ahead. She closed her notebook, then reopened it beneath candlelight shadows. Something about the smile suggested Eleanor knew exactly what happened. The clock ticked mechanically in the sudden, suffocating silence below. Mara wondered how long before Eleanor had discovered the truth.
