Damp evening fog clung to the rickety porch rails as the detective uncovered the bloodstained cloth covering the young victim. A shattered crystal wine glass lay scattered across the worn wooden floorboards near the crumpled form of the dead guest. A crumpled handwritten note was tucked beneath the victim’s cold stiff fingers its ink smudged from the damp night air. The detective’s gloved fingers brushed the crisp edge of the tiny handwritten message as a sudden knock came from outside.
