Rain dragged footprints across cobblestones. Lamp flickered by the doorway. Something heavy lay under coat. Crimson stain scored his shirt. Neighbors whispered behind curtained windows. Clock stopped dead at midnight. Footsteps approached, then suddenly halted. She opened the door slowly. Her face was pale, unreadable. Detective knelt beside the body. He listened to the silence. Something metallic glinted near fingers. Paper fluttered, a torn photograph. Names scratched into the glass. The rain kept faithful rhythm.
