Rain lashed the cobblestone street. Inspector Hollis adjusted his collar. The manor loomed above him. Every window stared back dark. Except one on the left. A single candle burned there. He climbed the stone steps. The oak door stood ajar. That detail troubled him deeply. Nobody left doors open here. He drew his service revolver. The hinges groaned like ghosts. Blood pooled across marble tiles. A woman lay face down. Her silk gown was scarlet. Pearls scattered near her hand. Hollis knelt beside the body. Her wedding ring was missing. Footsteps echoed from somewhere upstairs. Someone else was still here.
