⚠️ Spoiler Warning: This guide contains detailed spoilers for the entire novel. Proceed only if you've finished reading or are comfortable knowing the plot.

Summary

Kay Scarpetta eats antipasto and tries self-made CBD tincture from her sister Dorothy while they wait out a storm. Dorothy reveals she saw a private Facebook message from anthropology professor Cate Kingston to her husband Pete Marino, suggesting an “amazing find.” Dorothy admits jealousy over Marino’s interest in Kingston and recounts his hobby of collecting historic artifacts she considers junk. The conversation shifts to the AI avatar of Janet, Lucy’s deceased partner, which told Dorothy something “unspeakable.” Benton arrives with Merlin, reporting that the pet door chips have failed — a symptom of the larger computer problems plaguing the property. The kitchen lights flicker, hinting at an imminent power outage. Scarpetta’s thoughts circle back to Carrie, whom Dorothy unknowingly invited into their lives years ago.

Key Events

  • Dorothy applies her homemade CBD tincture to Scarpetta’s abrasions; Scarpetta notices the bottle has no label.
  • Dorothy confronts Scarpetta about Cate Kingston’s Facebook message to Marino, fearing a romantic connection.
  • Dorothy explains her jealousy and dissatisfaction with Marino’s metal-detecting treasures and his Bigfoot-related activities.
  • Dorothy recounts a hurtful comment from the AI Janet avatar (referred to as “Bad Janet” by Benton).
  • Benton enters with Merlin, reporting that the cat’s collar chip failed, locking Merlin outside for hours.
  • Benton tapes shut the cottage pet door; the kitchen lights flicker, suggesting an impending power outage.
  • Scarpetta internally connects the chip failure to the micro hard drive found in Brittany Manson and the killer’s chips.

Character Development

  • Kay Scarpetta remains the composed scientist and diplomat, soothing Dorothy’s outbursts while concealing her own anxiety about Carrie. She insists on the distinction between a real person and an AI avatar.
  • Dorothy reveals deep insecurity and jealousy, especially regarding Marino’s admiration for Cate Kingston. Her self-deprecation and alcohol consumption underscore her vulnerability. She also shows resourcefulness (creating the tincture) but lacks Scarpetta’s scientific rigor.
  • Benton Wesley is pragmatic and protective, dealing with the pet door malfunction, comforting Merlin, and delicately kissing Scarpetta’s injured face. He nicknames the AI Janet “Bad Janet.”
  • Marino is absent but discussed; his hobbies and secretive messages drive Dorothy’s jealousy. His enthusiasm for treasure hunting and Bigfoot is shown as a source of marital tension.
  • Cate Kingston is mentioned as an anthropology professor and Bigfoot researcher, portrayed by Dorothy as a threat.
  • Lucy is referenced through her sophisticated security system and 3D-printed cat collars, and her emotional state after losing Janet and Desi is noted.
  • Carrie is a looming shadow; Scarpetta recalls her past intrusion into their family, linking current malfunctions to possible sabotage.

Themes, Symbols, or Motifs

  • Jealousy and Trust – Dorothy’s unfounded jealousy over Marino and Kingston mirrors the erosion of trust within the family unit.
  • Technology as Threat and Comfort – Lucy’s advanced surveillance, AI avatars, and computer chips provide security but also fail and cause harm. The pet door chip breakdown echoes the killer’s chip removals.
  • Familial Secrets – Scarpetta keeps the truth about Carrie from Dorothy, just as Lucy and Benton kept information from Marino and her. This creates a cycle of concealment.
  • Objectivity vs. Emotion – Scarpetta’s calm reasoning contrasts with Dorothy’s emotional volatility; the chapter highlights the difficulty of separating rational analysis from personal feeling.
  • The Past Inescapable – Scarpetta’s flashback to Carrie and the persistent technical glitches suggest that old wounds and dangers remain present.

Why This Chapter Matters

Chapter 36 deepens interpersonal conflict within Scarpetta’s family while advancing two central mysteries. Dorothy’s jealousy over Cate Kingston introduces a potential suspect or complication in Marino’s investigation. The chip malfunction in Merlin’s collar directly ties the property’s technical problems to the serial killer’s MO, reinforcing that the killer may be targeting the household. Scarpetta’s guarded thoughts about Carrie remind the reader that an old enemy may still be active. The chapter also humanizes Dorothy, showing her as more than a foil — she is grieving, insecure, and struggling with Lucy’s trauma.

Study Questions and Answers

  1. Why does Dorothy suspect Marino of being unfaithful with Cate Kingston?
    Dorothy saw a private Facebook message from Kingston to Marino saying “anything you need, it would be my pleasure” and that she’s “excited about his amazing find.” Combined with Marino’s solo trip to the Bigfoot festival where Kingston was present, Dorothy fears a romantic relationship.

  2. What does the chip malfunction in Merlin’s collar suggest about the larger case?
    The chip failure mirrors the micro hard drive recovered from Brittany Manson and the chips cut from victims’ hands. It implies the killer has the ability to disable or tamper with computer chips, possibly using similar methods to compromise the Scarpetta household’s security.

  3. How does Scarpetta respond to Dorothy’s distress over the AI avatar of Janet?
    Scarpetta firmly reminds Dorothy that the AI is not a real person; it is a computer application modeled after Janet, not the deceased woman herself. She insists that Dorothy is not speaking to her daughter-in-law but to software, and that no genuine hurt can come from it.
