Small signs she misread, like burn marks on Juan Manuel's arms, foreshadowed the corruption quietly surrounding her. Molly's deliberate choice to withhold key information in her first police interview establishes the moral logic she applies throughout the novel. Her past losses—Gran's terminal cancer, Wilbur's theft, and the night she helped Gran die—forged an unusual ethical code that guides every decision she makes. When Rodney's betrayal becomes unmistakable, Molly's response is swift and cold, aimed not just at clearing her name but at genuine punishment. By the novel's end, she has steered a murder conviction onto the right villain for the wrong crime, and she reflects on this with complete serenity.
