The body lay crumpled near the marble fountain, blood pooling beneath the victim's expensive tattered dinner jacket in the moonlight. Detective Mara Voss adjusted her coat and stepped much closer, her sharp heels clicking against the cobblestones with deliberate precision. A broken champagne glass glittered very nearby, its contents long since spilled into the deep darkness of the garden path. She noted the complete absence of struggle, the calm pale hands, and the single missing pearl earring on the ground. Someone had known him well enough to get quite close, to smile warmly, and then to strike without any mercy. The cold night air smelled of roses, rain, and something metallic that suddenly made her throat tighten with familiar dread. She knelt down carefully, completely avoiding the blood, and gently lifted a crumpled invitation card from the victim's stiff fingers. Tomorrow's bold headlines would scream about pure tragedy, but tonight belonged to dark secrets only the dead man could reveal.
