Realization was a wrenching shock and a terrible disillusionment. Johnny was not waiting for him—not alive— He brought up the blaster, the dream-like state gone. The paw of the cave cat flashed out and struck the ship's master light switch with a movement faster than his own. The room was instantly, totally, dark.
