In the context of the narrative, the protagonist receives a letter from Mrs. Struan that leads him to a profound realization about corporate loyalty. Despite the dedication and service one may offer to a company, it operates on a self-serving basis and can discard employees without a second thought. This truth highlights the often brutal nature of corporate relationships, where personal sacrifices may go unrecognized and unappreciated.

This moment of clarity emphasizes the need for individuals to recognize their own worth beyond their roles within a company. Loyalty and hard work do not guarantee reciprocity from employers, suggesting that people should be mindful of the precariousness of their positions within organizations. Ultimately, it serves as a cautionary reminder about the often one-sided nature of corporate commitments.
