The rain hammered against the windows of Blackwood Manor while Inspector Sarah Chen studied the body on the floor. Lord Edmund Ashworth lay motionless near the marble fireplace, his silver pocket watch stopped precisely at eleven minutes past midnight tonight. A crystal decanter of brandy sat untouched on the side table, though the faint smell of almonds lingered in the air. Chen noticed immediately that the study door had been locked from the inside, with the only key resting in Edmund's pocket. The fire had burned down to embers, suggesting that several hours had passed since anyone tended to the flames. His wife, Vivian Ashworth, had discovered the body when she returned from her sister's estate in the neighboring village. She claimed the drive home took nearly forty minutes through the storm, which the muddy tires of her car confirmed. Chen's partner, Detective James Rowe, examined the locked windows and found every latch firmly secured without any signs of forced entry. The butler, an aging man named Graves, insisted that nobody had visited the manor since the dinner party ended the previous evening. Yet a half-empty teacup sat on the desk, still warm when Chen first entered the room this morning. Someone had been here recently, someone who knew the secret passages that the original architects built into the ancient walls. Chen pulled out her notebook and wrote a single question: who wanted Lord Ashworth dead enough to wait inside? Outside, the storm showed no signs of weakening, trapping everyone in the manor until the roads became fully passable again. The murderer, Chen realized, was still somewhere within these walls, watching them search and waiting patiently for their next opportunity.
