Rain hammered the manor windows while Detective Hale studied the silent library and the body beneath the oak desk tonight. A single candle guttered beside the scattered letters, and the air smelled sharply of old paper, cold iron, and fear. No servant answered the bell, and every corridor seemed to hold a quiet listener just beyond the next darkened doorway. Hale noted the missing dagger, the unlocked garden door, and one muddy footprint pointing toward the dark east wing stairs. Somewhere above them a floorboard creaked once, and Hale understood the killer had not yet left the silent old house.
