Thick white fog rolled slowly across the cold marble terrace. A grandfather clock struck midnight with twelve heavy, mournful chimes. Lord Reginald sat completely motionless inside his high-backed velvet armchair. A single drop of crimson blood dripped onto his shirt. The expensive crystal glass slipped silently from his lifeless fingers. Good scotch pooled quickly around his polished leather evening shoes. No one heard the stealthy footsteps retreating down the hallway. The killer left behind a delicate scent of sweet lavender. Now, the dark mansion held another very grim family secret. Only the golden retriever watched the shadow slip into night.
