The cold rain drummed rhythmically against the broken window pane. Detective Miller stepped over the yellow tape near the door. A single silver bullet lay silent upon the velvet rug. Dark shadows danced across the pale face of the victim. Nobody heard a single scream during the gala last night. He checked his golden watch and sighed at the time. The smell of expensive perfume hung heavy in the air. Someone had clearly scrubbed the wine stains from the floor. Only a broken champagne glass remained beneath the grand piano. The killer left behind a calling card made of silk. A long night for the police was only just beginning.
