Summary
On Friday, January 18, 1980, in Winchester, Massachusetts, Eddie Triplett drives off a cliff while his stepdaughter Daphne Zabriskie is in the front seat. The car crashes down through trees, and both are injured: Eddie breaks his ankle and Daphne suffers a deep cut on her head. They take inventory, and Eddie uses his tie and handkerchief to bandage her wound. Daphne finds her father Buddy’s emergency duffel bag in the back of the car, which contains a flashlight, medical supplies, a space blanket, and other survival items. As they wait through the freezing night, Eddie tells Daphne the story of Mary Carter, a Wyoming rancher who fell from her horse Whistler and was visited by deceased loved ones—her dog Marty, her best friend Susan, her father, and her son Jeffrey—before Whistler returned to carry her home. The story comforts Daphne and reinforces their hope of survival.

Character Development
Daphne Zabriskie – Demonstrates remarkable composure for a nine-year-old. She methodically inventories her resources, retrieves the survival bag, and stays calm even when seeing her own blood. Her quick mind solves the problem of who will find them (no one, since her mother is at the hospital with Leda). She also shows emotional depth by understanding the implications of Eddie’s story before he finishes it.
Eddie Triplett – Usually a composed adult, Eddie is frightened and in significant pain. He struggles to protect Daphne while managing his own injury. His decision to tell the Mary Carter story reveals his vulnerability and his need to comfort both his stepdaughter and himself. The story also underscores his identity as a writer and editor who believes in the power of narrative.
Buddy Zabriskie (mentioned) – Though absent, Buddy’s emergency bag demonstrates his care for his daughters and his preparedness. Daphne’s loyalty to the bag and her anger at the thought of it being thrown away shows her bond with her father.
Themes, Symbols, or Motifs
Storytelling as Survival – Eddie uses the Mary Carter tale to distract Daphne from fear and cold. The story mirrors their own situation: a person alone and injured, visited by the dead, and saved by a faithful connection. Daphne’s understanding that “they weren’t going to die” comes directly from the story’s resolution.
The Interstitial Space – The chapter’s title “Interstitial” suggests a liminal space between life and death, night and day, known and unknown. The crashed car hangs in the trees; the characters wait in darkness; the story blurs the boundary between the living and the dead.
Preparedness and Legacy – Buddy’s duffel bag serves as a physical reminder of his ongoing care. The bag contains exactly what is needed for survival, implying that love can bridge separation.
The Presence of the Dead – In Eddie’s story, deceased figures appear to Mary as comforting companions. This introduces a supernatural element that echoes throughout the novel, suggesting that the dead remain connected to the living.
Why This Chapter Matters
This chapter cements the relationship between Eddie and Daphne, transforming them from stepfather and stepdaughter into equal partners in survival. It introduces the novel’s central symbolic figure—Whistler the horse—through a nested story that foreshadows later themes of love, loss, and rescue. The emergency bag from Buddy also sets up a contrast between his absent presence and Eddie’s immediate care. The chapter’s tension and emotional payoff make it a pivotal moment in the narrative.
Study Questions and Answers
1. Why does Eddie choose to tell Daphne the story of Mary Carter?
Eddie tells the story to distract Daphne from their dangerous situation and to give them both hope. He consciously selects a tale that parallels their own experience—someone injured and stranded—but ends in rescue. By finishing with Mary mounting Whistler and heading home, Eddie assures Daphne that they, too, will survive.
2. How does Daphne’s discovery of Buddy’s duffel bag change the course of the night?
The bag provides essential tools: a flashlight that lets them see, medical supplies that allow Eddie to properly bandage Daphne’s head, and a space blanket that keeps them from freezing. Without it, their chance of surviving the cold and darkness would be much slimmer. It also emotionally connects Daphne to her father, reinforcing her sense of being cared for even in his absence.
3. What does Daphne’s ability to predict the ending of Eddie’s story reveal about her character?
When Daphne guesses that Jeffrey will appear, and later that Mary must whistle for the horse, she demonstrates an intuitive understanding of narrative structure and emotional truth. Eddie is “shaken by how quickly she’d gotten ahead of him,” which highlights Daphne’s intelligence and perceptiveness. It also foreshadows her stated ambition to become a novelist.
