Larry LaSalle is initially presented as a heroic figure in the novel but his character develops in a more negative direction. He is admired by the community for his war service but is actually manipulative and predatory towards younger people like Nicole. A turning point occurs in Chapter 11 where Larry's betrayal of Nicole and Francis is revealed, establishing him as a villain. While Larry commits some heroic acts, the novel questions what truly makes someone a hero and suggests appearances can be deceiving.
