Summary

Emily reacts with shock and tears after learning that Duke is her biological father. Maisie and Nell comfort her, and Lara wonders if she should have told the truth earlier. Emily admits she would not have believed it as a teenager. The sisters then turn to lighter topics: Maisie recounts helping a dog deliver puppies, discovering Duchess on the road, and returning home to learn of Duke’s death. Lara describes being woken by Maisie hearing the news. Finally, Lara shares a secret she has kept for decades: after her grandmother’s death and before Joe returned, she visited Duke in a psychiatric hospital outside Boston. He had called her, and she went under the name Emily Webb. Inside the facility, Duke manipulated her into having sex in a bathroom. After leaving, she met Sebastian (Duke’s brother) outside. He took her to dinner, and they spoke about Ripley, Duke’s career, and the past. Sebastian revealed that Ripley had been in love with Lara. Later, Lara discovered she was pregnant and chose to have an abortion, never telling anyone. She ends the story there, feeling only gratitude for the choice she made alone.

Character Development

Lara: This chapter fully exposes her vulnerability and her lifelong habit of protecting others by withholding painful truths. Her visit to Duke shows a woman still under his spell, capable of extraordinary foolishness, yet also resilient enough to later make a lonely, pragmatic decision about her pregnancy.
Emily: She moves from a romanticized fantasy of a famous father to a painful reality, ultimately accepting the truth and rejecting the story she had invented.
Maisie: Her practical, caretaking nature shines through both the puppy birth and the way she supports her sister and mother.
Nell: She offers quiet comfort and gently challenges Emily’s need for a fairy-tale father, grounding her in the present family bonds.
Duke: Even in a psychiatric ward, he remains manipulative and self-absorbed, using Lara for his own needs without regard for her feelings.
Sebastian: He appears as a loyal brother and a steady, caring presence, contrasting sharply with Duke’s chaos. His revelation about Ripley adds depth to Lara’s past.

Themes, Symbols, or Motifs

Secrets and the Weight of Truth: Lara’s final secret—the abortion—underscores how some choices are so private they can never be fully shared, even with a loving family.
Motherhood and Sacrifice: The chapter contrasts biological parenthood (Duke) with the chosen, nurtured relationship between Lara and Joe. The abortion is a sacrifice of a possible child to preserve Lara’s future with the family she later builds.
The Pull of the Past: Lara’s inability to refuse Duke, even years after their affair, demonstrates the enduring power of first love and trauma.
Water and Drowning: Duke’s death by drowning echoes the earlier swimming scenes and his own risk-taking nature; Lara’s memory of walking into a lake symbolizes her surrender to his world.
The Hospital as a Stage: The rehab facility is theatrical—a “fishbowl,” a “bad bar,” patients performing for staff—mirroring the performative aspects of Duke’s life.

Why This Chapter Matters

Chapter 21 is the emotional and narrative climax of Lara’s summer storytelling. It completes the picture of her past with Duke, revealing the depth of her entanglement and the hard choices she made afterward. The secret she keeps from her daughters—the abortion—is the one decision that remains wholly hers and shapes her identity as a mother who chose her family deliberately. This chapter also closes Emily’s story arc: she moves from worshipping a fantasy father to accepting that her real father is Joe, the man who raised her. The chapter’s tapestry of birth (puppies), death (Duke), and difficult renewal (Lara’s pregnancy decision) prepares the reader for the novel’s final reflections on family and fate.

Study Questions and Answers

1. Why does Lara decide not to tell her daughters about the abortion?
Lara keeps the abortion secret because it is the one choice she made entirely by herself, without obligation to Duke or anyone else. She feels only gratitude for that decision, which allowed her to become the mother she is to Emily, Maisie, and Nell with Joe. Revealing it would disrupt the story she wants her daughters to understand about their family’s foundation.

2. How does Sebastian’s revelation about Ripley change the reader’s understanding of Lara’s past?
Sebastian’s comment that Ripley was “in love with you” paints Ripley as a protective, caring figure who waited for Lara “to grow up.” It suggests that Lara had other genuine admirers besides Duke and that her relationship with Ripley might have been more complex than simple friendship. It also adds a layer of missed connection to the Tom Lake summer.

3. In what ways does the chapter contrast Lara’s two pregnancies (Emily and the aborted child)?
Lara’s pregnancy with Emily resulted from a loving relationship with Duke and later became a part of her life with Joe. The second pregnancy, from the manipulative encounter in the hospital, was a mistake she chose to end alone. Together, they illustrate the difference between a child born out of shared history and one conceived in a moment of weakness—and how Lara’s agency in each case shaped her motherhood.
