Summary

Detective psychologist Alex Delaware uses his professional title to inquire at two residential facilities in Culver City and West Los Angeles, searching for Lynne Matthias. The first facility, Vanguard Developmental Center, specializes in seniors with dementia and has no record of anyone named Matthias.

Delaware’s second call connects him to Safe Place, a residential treatment facility just under a mile from Martha Matthias’s home. The receptionist transfers him to Pam Buttons, the facility’s supervisor, who is at home. She immediately asks if Lynne is hospitalized, revealing that Lynne has been missing for a week. Buttons explains Lynne told staff she was going to her mother’s house—a routine overnight visit—but never returned. When Buttons tried to file a missing-persons report, officer Harvey Pocan dismissed her concerns, stating adults are free to come and go, and directed her to an online form. Despite explaining that Lynne functions cognitively at roughly a twelve-year-old’s level, Buttons received no follow-up. Delaware promises a detective will contact her, and Milo Sturgis calls her minutes later. Buttons refuses to let investigators interview other residents at Safe Place because it would be disruptive and it’s her day off but volunteers to come to the station for an interview. Milo suspects she may be forthcoming—or deliberately creating that impression.

Character Development

Alex Delaware

Delaware continues to act as Milo’s investigative partner, using his professional credentials to open doors. His methodical phone work reveals institutional records gaps and uncovers Lynne’s unreported disappearance. The chapter underscores his dual role as both a trained psychologist and an unofficial detective.

Pam Buttons

Introduced as the supervisor of Safe Place, Buttons comes across as frustrated but cooperative. She advocates for Lynne’s vulnerability yet agrees to a police interview without a lawyer. Her willingness to talk—despite her anger—raises questions about whether she is genuinely helpful or managing perceptions.

Milo Sturgis

Milo’s efficiency and cynicism are on display. He labels Harvey Pocan a “total waste of space” and quickly follows up with Buttons. He vocalizes suspicion that Buttons’ cooperation could be strategic, not solely altruistic.

Harvey Pocan

Mentioned only in conversation, Pocan personifies the systemic neglect Buttons encountered. His dismissiveness toward a missing vulnerable adult reflects poorly on police responsiveness and sets up a recurring theme of institutional failure.

Lynne Matthias

Through Buttons’ account, Lynne emerges as a dependent adult functioning like a preteen, reliant on routine and structure. Her disappearance after Martha’s murder deepens the mystery—was she abducted, did she flee, or was she involved?

Themes, Symbols, and Motifs

Institutional Neglect and Indifference

Pam Buttons’ fruitless attempts to report Lynne missing expose a gap in how law enforcement handles vulnerable adults. Officer Pocan’s brush-off and the silent online system symbolize a broader unwillingness to protect those who cannot fully advocate for themselves.

Vulnerability of the Disabled

Lynne’s cognitive functioning at a twelve-year-old’s level heightens the urgency of her disappearance. The chapter forces readers to confront the precarious safety net for disabled adults living semi-independently.

Bureaucratic Opaqueness

The link between Safe Place’s warm front (a house similar to the Kadar property) and the cold bureaucracy of the police underscores how institutional care can mask deeper systemic failures. Martha’s choice of such a facility for Lynne reflects her maternal protectiveness, now tragically undercut.

Parallel Investigations

Delaware and Milo’s coordinated phone calls demonstrate how informal detective work can succeed where official channels stall. Yet the chapter hints that they, too, may be playing a version of the same avoidance game Buttons experienced.

Why This Chapter Matters

Chapter 20 pivots the investigation from a murder scene to a missing-person case with potential ties to the homicide. It introduces a key witness—Pam Buttons—whose cooperation or lack thereof could shape the rest of the book. The revelation that Lynne disappeared around the time of Martha’s murder raises urgent questions: Is Lynne a second victim, a suspect, or a frightened witness hiding from a killer? The chapter also critiques police ineptitude, personified by Pocan, and foreshadows a tense interview in the next chapter. By locating Safe Place physically close to Martha’s home, Kellerman weaves geography, psychology, and suspense into a tight narrative coil.

Study Questions and Answers

  1. Why does Pam Buttons feel the police failed Lynne Matthias? Buttons explained that she tried to report Lynne missing immediately but was told adults can leave voluntarily and was directed to an online form. Even after stressing Lynne’s cognitive limitations, she received no callback. Officer Pocan’s dismissive attitude epitomizes the neglect.

  2. What is the significance of Safe Place’s proximity to Martha Matthias’s home? The facility is less than a mile away, allowing Martha easy access to visit Lynne. This closeness suggests Martha chose the center intentionally to keep her daughter nearby and safe, which makes Lynne’s disappearance and Martha’s murder even more tragic and suspicious.

  3. How does Milo’s reaction to Buttons’ cooperation reveal his investigative mindset? Milo immediately questions whether Buttons is genuinely transparent or if she wants to appear cooperative to deflect scrutiny. His skepticism reminds readers that even helpful witnesses warrant cautious examination in a homicide investigation.
