Fog lay thick over Elm. Streetlights blinked like tired eyes. Footsteps stopped beside the bench. A shape lay unnaturally still. Pale hand curled around note. Rain had washed away prints. Glass glimmered where someone struggled. A boot left a mark. Neighbors whispered behind drawn curtains. The note read: Come alone. Detective Hart hadn’t finished coffee. He frowned at the scene. Her eyes stared toward moon. A pocket watch ticked softly. Someone had wound it recently. The air smelled like iron. He knelt, avoiding splattered leaves. He found a photograph torn. Someone watched him from shadows.
