Definition of Metaphor
At the end of the first chapter, there are two allusions to the biblical Book of Genesis:
And Lot’s wife, of course, was told not to look back where all those people and their homes had been. But she did look back, and I love her for that, because it was so human. So she was turned to a pillar of salt. So it goes. [...]

Derby raised his head, called Campbell a snake. He corrected that. He said that snakes couldn’t help being snakes, and that Campbell, who could help being what he was, was something much lower than a snake or a rat—or even a blood-filled tick.
