Summary

Waylon arrives at Isabelle’s house to cook dinner, and after an initial awkwardness, they fall into easy companionship. Over wine and chicken marsala, Isabelle asks about the cold case Waylon mentioned on the plane. He describes the disappearance of a girl thirty years ago, taken by a crossing guard named Guy Rooney, who kept her in his basement for months before killing her. Rooney confessed when the police found evidence, and the case was closed. The story unsettles Isabelle, making her think about her own neighbor and the mysterious man on his porch. As they eat, Waylon gently asks about her past, and Isabelle admits she moved to Savannah for a job but stayed for a man—Ben, her former boss. She explains that Ben was married when they met, though their relationship never became physical. She then reveals that Ben’s wife, Allison, died, and that she and Ben later married. The conversation shifts the mood from light to heavy, but the intimacy between them grows.

Character Development

Waylon is revealed as a persistent investigator who won a cold case through exhaustive interviews. He shows empathy, not judgment, when Isabelle confesses, and he creates a safe space for her to open up.

Ben is further characterized through Isabelle’s reminiscence: a man who kept his relationship with Isabelle ambiguous and never physically crossed lines, yet emotionally cheated on Allison.

Allison remains a shadow figure, but her death is now confirmed as a fact that shaped Isabelle and Ben’s union.

Why This Chapter Matters

This chapter deepens the bond between Isabelle and Waylon, transitioning their relationship from investigator/subject to genuine partners. It provides critical backstory on how Isabelle met Ben and the unresolved guilt she carries. The cold case narrative mirrors the central mystery of Mason’s disappearance, emphasizing the terror of a “resolution” that brings only grief. It also reinforces Isabelle’s suspicion of her neighbor, setting up future investigative action.

Study Questions and Answers

1. Why does Isabelle decide to tell Waylon about her affair with Ben, even though she is ashamed?
She realizes Waylon will likely hear the story from others (e.g., Detective Dozier). She wants to control the narrative and present her perspective, and she trusts that he will not judge her harshly after their week together.

2. How does the story of Guy Rooney parallel Isabelle’s own situation?
Both involve secrets hidden in plain sight—Rooney in his basement, Isabelle in her emotional affair. The case also shows that even a “resolution” (finding the truth) can be devastating, which Isabelle fears for Mason’s case.

3. What does Waylon’s reaction to Isabelle’s confession reveal about his character?
He does not criticize or withdraw; instead, he listens calmly and continues cooking. This shows his professional detachment as an investigator and his personal empathy, making him a trustworthy confidant.
