Chapter 26 Summary

Denis Fortin speaks with Peter and Clara. Myrna and Gamache discuss Beauvoir’s obvious pain, and Myrna assures him, “He loves you. That’s his road home” (311). Castonguay begins angrily ranting, criticizing Clara’s art, then Peter’s, then Fortin’s ambition. Marois tries to get Castonguay to leave, but he accuses him of stealing a client and tries to strangle him. Gamache and his team arrest him.


Gamache and Beauvoir return to the party, as a storm intensifies outside. Using Clara’s art as a metaphor for the case, Gamache notes that Lillian’s death, like Clara’s paintings, is about chiaroscuro—the interplay of light and dark. He turns to the question of change, and asks Suzanne if she truly believes in her own redemption, querying, “is it real hope, or just a trick of the light?” (315).

Chapter 27 Summary

Gamache continues his disquisition, pointing out that Suzanne lied about being the subject of Lillian’s review. He points out that Pineault has also been deceptive, as he has not disclosed that he knows Castonguay because he once attempted AA. Pineault betrayed this when he hid from Castonguay at the bistro, and Gamache confirmed it during their earlier argument. Lillian tried to show him her art, which hints at their history. Castonguay would lose his best client if they found out about his drinking, so Pineault became afraid Lillian might have leveraged the information against him.


Clara assumes the role of investigator, hypothesizing that Castonguay saw Lillian as the artist who would save his career and turned on her when he discovered she had also gone to Marois. Gamache listens, but says clearly, “Andre Castonguay didn’t kill her. One of you did” (321).

Chapter 28 Summary

Gamache reminds the group that Lillian held her beginner’s chip when she died, signaling she was trying to follow the 12 Steps in Three Pines. Gamache says that Lillian’s career as a critic was its own moral crime, where she “murdered, or tried to murder, many people […] by taking away their dreams’” (325). Gamache points out that one of Lillian’s efforts to apologize contributed to her death. He watches Beauvoir quietly move to the door, blocking the killer’s potential exit.


Gamache suggests that while part of Lillian truly did want to repair things with Clara, her choice of timing reveals that she had not truly considered her motives, as does her choice of a bright red dress. Gamache explains that the murderer gave Lillian the directions to Three Pines, both to carry out his plan to kill and make sure Clara was implicated.

Chapter 29 Summary

Clara turns her gaze to Denis Fortin, who is unrepentant. He says of Lillian that, “she killed the best part of me” (328). The storm outside intensifies. Fortin explains that Clara also harmed him, as the success of her show proved that his earlier criticisms of her were unfounded.


He intentionally killed Lillian at her home, hoping that she would forever associate the evening with the tragedy. Lillian gave him the idea when she mentioned she had been looking for Clara, so Fortin helped her find the party, after apologizing to Clara to ensure his own invitation. Fortin mocks Clara’s choice to forgive him. When Fortin is unmoved by Gamache’s reminder that Lilian was trying to change, Suzanne points out she was able to move on and help Lillian.

Chapter 30 Summary

The next morning, Gamache and Pineault walk together. Gamache notices Brian talking to Ruth and says he thinks the young man is an impressive person. Pineault corrects his assumption that he is Brian’s sponsor. Brian has been sober for several years longer than the justice, and they met because Brian carefully made amends for the death of his granddaughter and helped him get sober himself.


At the Morrow house, Clara watches Peter pack. She has asked for a year’s separation. She assures him they will have dinner together in a year. Peter nearly tells Clara the truth about his role in Lillian’s review, but he lies, telling her he was not effusive enough: “I told her I loved your art, but I could have been clearer” (337). Clara kisses him goodbye. Beauvoir takes a pill and calls Annie.


Peter finds Gamache outside his car, as they both watch Ruth, waiting for Rosa. Peter insists the wait is futile. Olivier comes up to Ruth and gives her his sweater, and she offers him an insult, signaling she has forgiven him. Ruth turns to the sound of a quack and wings flapping. Peter drives away from the village. Gamache takes Ruth in, and notices, “in her weary eyes there was a tiny dot. A glint. A gleam” (339).

Chapters 26-30 Analysis

Gamache, like the AA members, faces his grief fully in this section and remains connected to the world, helping to bring closure to The Challenges of Grief and Trauma in the plot. The moment of sympathy between Gamache and Suzanne, where he understands why she chose sobriety over resentment, signals that he, too, has chosen healing. However, even his insights remain imperfect, especially vis-a-vis Brian and Pineault. Here, the “trick of the light” is the nature of appearances: Gamache has assumed that the distinguished judge had the real power in the relationship and that Brian had no value or significance in comparison. Gamache accepts his mistake, affirming that he is willing to evolve.


By contrast, Fortin and Castonguay are each cautionary tales about the refusal to face emotions or to overcome past setbacks in a productive way. Castonguay remains bitter because he pursued recovery out of fear for his career, not out of a real desire for recovery. Fortin, for his part, allowed his grief for his ambition to turn to hatred, which only grew when he saw Clara’s compassion as a threat to his career, and not as an opportunity to truly change.


Beauvoir is still in a more ambiguous position at the end of the novel, setting up his character arc for later books in the series. He remains Gamache’s stalwart ally during the investigation, such as by blocking Fortin’s exit quietly, without fanfare or recognition from anyone aside from Gamache. Nevertheless, he does not promise anyone that he will attend rehab or therapy, suggesting he is placating his mentor and still avoiding the work of real healing. Beauvoir does, however, still have strong relationships. As Myrna points out, his trauma comes from love, a love that he extends to others rather than himself. He finally decides to call Annie, but only after taking a pill. Beauvoir has not yet learned to love himself while pursuing romance, foreshadowing how he will have to face his traumas directly in the coming books.


Clara takes the thematic resonance of The Destructive Power of Jealousy in the case to heart. She fully faces that Peter’s jealousy has damaged her and asks for space from him. She also learns from her earlier impulsivity, as she asks Peter to give her a year, rather than rushing either of them into a reconciliation. Clara’s art mirrors her emotional journey: She has not lost her love for people, and what Marois assumed was a “trick of the light” is her true self. Peter, in contrast, is reluctant to grapple with how jealousy has wrecked his marriage. He tells Clara only part of the truth about his role in her estrangement from Lillian, claiming that he offered faint praise of her work rather than admit that he has been harsh and cruel for much of their relationship. Peter thus maintains the image of a supportive and loving spouse at the cost of authenticity, enabling his jealousy to go on festering.


As the novel comes to a close, Gamache takes on new prominence, as if he is teaching his interlocutors about humanity as much as he is solving a crime. Though he continues to struggle with his own emotional pain, Gamache sees the suspects around him clearly. Others, like Pineault and Clara, try to take on the detective’s role, assuming Castonguay’s active alcohol dependency ended in violence. Gamache points out that the key is in paintings, not those who purchase them: The question of Lillian’s repentance, and Fortin’s destroyed, then warped, ambitions, is bound up in their artwork, bringing Art as a Reflection of Self to its culmination.


The solution to Lillian’s murder does return a kind of peace to the village, in keeping with the requirements of the genre. Rosa returns, ending Ruth’s desperate longing, and she accepts comfort from Olivier with her usual acerbity. Though some inhabitants leave, and others have not fully faced the lessons of the Dyson case, Three Pines is no longer a crime scene. Not all the shadows are removed form Gamache’s world, but the novel’s ending suggests that relationships will always bring light and solace to those who can find and nurture them.
