Rain tapped politely against the shuttered windows of Blackthorn Manor. At midnight, Eleanor Vale discovered the body beneath watching portraits. An ivory cane lay beside his pale and bloodless hand. No wound marked him, yet terror widened his cloudy eyes. Eleanor knelt, hearing distant laughter drift through the locked house. Behind her, the grandfather clock chimed thirteen slow deliberate times. Then every candle died, leaving one whisper beside her ear. “You arrived early,” breathed a voice from the darkness upstairs. Eleanor seized the cane, noticing fresh mud upon its handle. Outside, someone knocked once, then waited without entering the manor.
