The rain hammered Blackwood Manor as Detective Mara Voss arrived to find the host dead beside his untouched cold dinner. A single candle guttered above the silverware while every guest pretended shock and quietly counted all the exits near them. The lord's signet ring was missing though his pocket watch still ticked inside his waistcoat with obscene calm precision tonight. Mara noted frost upon the windowpane despite the fire roaring and she wondered who had wanted the room so cold. Then the telephone rang from the study though the line had been cut since breakfast according to the trembling maid.
