Rain hammered the silent manor. Inspector Doyle arrived at midnight. Ashworth lay dead near fireplace. A crimson stain spread slowly. Nobody had heard the gunshot. Seven guests remained inside Blackwood. Each of them had secrets. Doyle studied every face carefully. The butler trembled by doorway. Someone in this house lied. Doyle smiled, though nobody noticed. The game was afoot now.
