Rain hammered mansion windows as Detective Mara Voss arrived alone. The butler met her at the door with trembling hands. Inside, a grandfather clock ticked beside the silent study doorway. A wealthy collector lay dead beneath his polished oak desk. Mara saw the silver letter opener deep in his chest. The wound was neat, deliberate, and strangely free of blood. No footprints marked the carpet, and no window stood open. Seven guests waited inside, each wearing expensive formal evening clothes. The butler swore nobody entered; mud stained the hall runner. Mara knelt beside the body and noticed a missing cufflink. Its twin glittered beside him, still clean and completely untouched. She looked up when thunder shook the house; someone screamed.
