The night was dark, silent. Shadows stretched across the alley. A scream pierced the cold air. Detective Lane arrived at scene. Yellow tape cordoned off area. Victim lay beneath flickering streetlamp. Blood pooled in jagged patterns. No witness stepped forward yet. Rain began to softly fall. Mystery deepened with each moment.
