At midnight, the manor's clocks stopped beneath the gathering storm. Inspector Vale arrived moments later, carrying one bloodstained black umbrella. Inside, every guest stood silent beside the library's locked door. Only the butler noticed muddy footprints leading toward the fireplace. Then someone laughed upstairs, though every staircase remained visibly empty. Vale examined the corpse, recognizing the victim's familiar silver ring. His own hand bore its matching twin, strangely still warm. Outside, the storm erased every road leading away from Blackwood.
