In "The Dumas Club" by Arturo Pérez-Reverte, the narrative follows a group of literary enthusiasts who delve into the works of Alexandre Dumas. Their passion for literature intertwines with the exploration of ideas about morality, betrayal, and the essence of humanity, particularly through the lens of Dumas' characters. The discussions spark reflections on the nature of courage and the heart's true role in shaping one's destiny.

The quote, "They suspected him that he had no heart," from R. Sabatini's "Scaramouche," resonates within the themes of the story, emphasizing the ongoing struggle between appearance and reality. It suggests a deeper examination of character, questioning whether one's actions reflect their true nature or if external perceptions hinder the understanding of one's moral compass. This portrayal adds depth to the characters' journeys within Pérez-Reverte's intriguing narrative.
