Rain polished the manor windows. Inside candles trembled beside silver. Guests whispered through velvet hallways. Midnight chimed and laughter died. Lady Harrow clutched her pearls. Then came the strangled scream. Everyone turned toward the library. Colonel Vale lay facedown bleeding. His back held ornate scissors. The locked door swallowed accusations. On the mantel silence ticked. Detective Gray removed wet gloves. Nobody noticed the missing portrait.
