The rain-slicked cobblestones gleamed under the dim streetlamp as Detective Harlow stepped out. A single gunshot had shattered the quiet of the evening, drawing her to this alley. She found the body crumpled against the damp brick wall, a crimson stain spreading slowly. The victim's hand clutched a torn photograph, the image half-hidden by blood and shadow. No witnesses lingered, only the distant hum of traffic and the pattering rain's persistence.
