By the time Inspector Vale reached Blackthorn House, the rain had washed every footprint from the gravel beneath its windows. The front door stood open, though the butler insisted he had locked it moments before the grandfather clock struck midnight. In the drawing room, Lord Ashcombe sat beside an untouched brandy, his throat marked by a thin ribbon of blood. Someone had placed a silver key upon his tongue, and someone else had carefully turned every portrait toward the wall. Vale counted five people waiting near the fireplace, all dressed for dinner, all watching the dead man's motionless hands instead. His daughter broke the silence first, asking whether a man could still change his will after somebody had killed him. Before Vale could answer, a faint knocking sounded beneath the floorboards, three measured taps followed by a long, deliberate pause. The butler dropped his candle, and for the first time that evening, the widow looked genuinely afraid of the dark.
