Rain hammered Blackwater House as Detective Mara Venn finally arrived. Nobody greeted her, and the heavy front door stood open. Somewhere upstairs, a woman screamed once and then began laughing. Mara climbed alone, counting every door along the winding staircase. The fifth revealed Lord Vane, dead beside his steaming coffee. A silver knife pinned his left sleeve to the desk. Yet no wound marked him, and no blood appeared anywhere. On his blotter lay six brass keys and one warning. The warning promised death behind the seventh door at midnight. Behind her, the study door locked with a soft click. Then laughter resumed below, accompanied by slow and deliberate applause.
