Rain hammered the windows of Blackwood Manor that stormy night. Detective Mara Quinn arrived precisely at eleven o'clock sharp tonight. The butler opened the heavy door, his face deathly pale. She found Lord Ashford slumped coldly over his mahogany desk. A single shattered wine glass lay near his lifeless hand. Blood mixed with red wine, indistinguishable within dim flickering candlelight. Mara whispered, someone inside this house wanted him dead tonight.
