Rain tapped the window while the body lay pale beneath the chandelier, silent and still before midnight arrived that night. Detective Mara entered slowly, her coat dark with rain, and studied the bloodstained carpet where no weapon could be seen. The guests stood together in whispered fear, each face hiding motive, each hand trembling beneath the harsh golden light nearby. A note rested beside the victim, written in violet ink, promising that someone would pay before morning came for them. Mara knelt, noticed a torn pearl, and understood the killer had left one perfect clue for her alone to see.
