After emerging from the cave, Pendergast apprehends Ms. Kraus, and explains what has been going on: during the 1930s, the young Ms. Kraus became pregnant with an illegitimate child; her father, who was a sternly religious man as well as a bootlegger, imprisoned her in the cavern for the period of her pregnancy, and that is where she bore her son, whom she named Job. Her father never allowed Job to see the light of day, but, later, after he had died, Ms. Kraus grew to like the idea of keeping her son safe and loved inside the cave. The result was a pure sociopath, who spent the first fifty years of his life without contact with the outside world at all, or with any human being except his mother. He also became physically powerful from roaming and climbing around the caves.
