The snow began before dawn. By breakfast, the roads vanished. Inside Blackthorn House, clocks stopped. At eight, someone found Margaret. She lay beneath the chandelier. Blood darkened her white gloves. The library door remained locked. Its only key was missing. Detective Vale arrived before noon. He found seven frightened guests. Each claimed to love Margaret. Nobody mentioned the eighth chair. Nobody explained the wet footprints. They led toward the fireplace. None led away from it. Then Margaret’s telephone began ringing. Vale lifted the trembling receiver. “Run,” a child’s voice whispered. “She isn’t the first tonight.”
