Summary

Faith Mitchell rides a gassy horse to the McAlpine compound, terrified of falling. She finds a cold GBI UTV and a satellite phone but cannot raise Will. Searching the empty compound, she meets Frank Johnson, who says his wife Monica is recovering from a bad hangover. Bitty McAlpine emerges, dismissive of her daughter’s murder, and reveals she wants Dave released, not justice. Sara Linton arrives, and Faith updates her. Faith then follows Fishtopher Trail to find Will, falls into mud, and spots Will’s gear (Amanda’s gun, phones) scattered on the ground. Panicked, she plunges into the creek, emerges downstream, and finds Will alive with Kevin Rayman carrying the body of Bryce “Chuck” Weller. Sara arrives and declares Chuck was poisoned, not drowned.

Key Events

  • Faith arrives at the lodge after a harrowing horse ride and cannot contact Will via satellite phone.
  • Bitty McAlpine shows indifference toward Mercy’s murder and prioritizes Dave’s release.
  • Sara informs Faith that Mercy was twelve weeks pregnant and describes the weapon as a red-handled half-tang steak knife.
  • Faith interviews Alejandro, the chef, who admits to an affair with Mercy and describes her history of bruises.
  • Faith discovers Will’s abandoned electronics and gun near the creek, triggering a desperate search.
  • Will and Kevin find Chuck’s body; Sara confirms poisoning.

Character Development

  • Faith Mitchell: Her fear of nature and fierce protective instinct for Will emerge clearly. She admits to being terrified of losing him and briefly lashes out in relief.
  • Bitty McAlpine: Reveals deep favoritism toward her sons, calling Dave “my heart,” while dismissing Mercy as “terrible.” Her coldness toward her daughter’s death underscores the family’s dysfunction.
  • Alejandro: Discloses the casual sexual relationship with Mercy and acknowledges he noticed bruises but chose not to intervene, expressing guilt without remorse.
  • Will Trent: Remains calm and methodical even after nearly drowning, focusing on the case. He notes Chuck’s incel language and jealousy toward Dave.

Themes, Symbols, or Motifs

  • Isolation and secrets: The lodge’s remote setting amplifies the family’s power to hide abuse and control narratives, as Bitty’s lies and omissions suggest.
  • Fatalism: Both Bitty and Alejandro speak of Mercy as if her violent fate was inevitable. Penny’s earlier comment (“she never stood a chance”) echoes here.
  • The natural world as threat: Faith’s constant battle with mud, snakes, and the creek mirrors the chaos of the investigation. The Rope Trail, used only by staff, becomes a symbol of hidden shortcuts and dangerous knowledge.
  • Weapon evidence: The red-handled half-tang steak knife becomes a concrete clue linking the murder weapon to the lodge’s kitchen or guest cottages.

Why This Chapter Matters

This chapter raises the stakes dramatically by introducing a second dead body—Chuck—and confirming he was poisoned, not a drowning accident. Now the agents must determine whether Chuck killed Mercy and then himself, or if there is a second, connected killer. The discovery of Mercy’s pregnancy provides a powerful new motive for someone to have wanted her dead, and the detail about the knife handle points toward a cheap, common item that anyone in the lodge could have used. Faith’s emotional vulnerability here also deepens her partnership with Will, showing how personal the case has become.

Study Questions and Answers

  1. What new evidence about the murder weapon does Sara share, and how does it change the search?
    Sara explains that the blade used on Mercy was a five-inch half-tang, meaning a cheap steak knife with a red plastic handle and a thin metal skeleton inside. The killer drove the blade to the hilt, leaving traces of red plastic in the wounds. The agents must now search the lodge for a matching red-handled knife.

  2. Why does Faith suspect that Chuck might have been poisoned rather than a drowning victim?
    Faith recalls Alejandro mentioning that Chuck has a peanut allergy. Will describes Chuck drinking from a water jug just before falling into the creek. When Sara later states “He was poisoned” rather than citing peanuts specifically, it confirms that the death was not accidental.

  3. How does Bitty’s attitude toward Mercy compare to her attitude toward Dave, and what does that suggest about the family dynamic?
    Bitty calls Dave “my heart” and “sweet as honey,” even while he is in custody, but describes Mercy as “terrible” and “full of piss and vinegar.” She refuses to believe Dave would hurt Mercy and is more concerned with getting him released than with finding her daughter’s killer, revealing deep parental favoritism and a possible motive for family conflict.
