The grand ballroom glistened under chandeliers’ golden glow. Dust motes swirled in the air, catching the flickering candlelight. A single scream echoed through the opulent, crowded hall. Eyes darted everywhere, searching for the source of that sound. Silent whispers filled the room, each voice carrying a secret. A woman clutched her throat, her face pale with shock and fear. The orchestra’s music paused abruptly, as if nature itself held its breath. Gasps rippled through the guests, all suddenly aware of danger’s nearness. A shadow moved swiftly across the floor, unseen until it was too late. The victim’s body lay sprawled on the polished marble, lifeless and cold.
