What is the main theme in the novel, Glitz?

Similar to his other novels, Leonard develops a favorite theme: An ordinary man, fundamentally good, gets into a scrape, but (in this novel anyway) ultimately prevails over the greedy, evil, and amorally ambitious. Leonard in this book again is reworking a prevalent theme of the westerns he wrote for so long, but the variations he weaves in Glitz on that hackneyed theme sustain it through this complex novel.
