Lethal Prey Chapter 10: A Prosecutor’s Psychopathic Murder

⚠️ Spoiler Notice

This page contains detailed spoilers for Chapter 10 of Lethal Prey by John Sandford. If you have not read the chapter, proceed with caution.

Summary

The chapter opens with Amanda Fisk driving her Mercedes into a gym parking lot, careful to avoid door dings. Inside the locker room, acquaintance Rebecca Jones excitedly tells her that a true-crime group has found a knife believed to be the murder weapon from the Doris Grandfelt killing—a knife that came from Bee, the accounting firm where Amanda once worked and where Grandfelt was murdered. Amanda dismissively corrects Jones (“Doris, not Delores”) and reveals she barely knew the victim, though she notes that police suspected Grandfelt had been involved with rough people on Hennepin Avenue and rumors of prostitution. During her Pilates class, Amanda reflects on her former job as a contracts attorney at Bee and her current position as an assistant county attorney in the criminal division, where she thrives—partly because she is a criminal herself, never caught.

After her workout, Amanda calls her office, claiming a knee injury, then drives home to her Summit Avenue mansion. There, she resents her husband Timothy’s two Jack Russell terriers, which bounce balls off the house each morning. She devises a plan to kill him by staging an accident. Using kitchen gloves, duct tape, and a mop handle, she taped the Chuckit ball launcher to the mop and placed two Chuckit balls in the gutter outside their balcony. When Timothy returns home, she lures him to the balcony, pretending the dogs rolled balls into the gutter. As he leans over to retrieve them, she grabs his belt and jacket collar and heaves him over the railing. He falls fifteen feet onto the flagstone patio, dying instantly from a crushed skull and broken neck.

Amanda then calls 9-1-1, feigning grief. The police treat it as an accident, and the body is taken to the morgue. Alone, she hoses blood off the patio and goes to bed in her separate queen bed, thinking about her kills. We learn that Timothy was the sixth person she has killed; Doris Grandfelt was number three, and Amanda knows that Timothy deposited DNA in Grandfelt’s body. Killing him prevents a murder charge against him and preserves their considerable wealth—money she can now enjoy alone, possibly on St. Thomas. The chapter ends with a flashback to an earlier kill: Don at the top of the stairs with popcorn and beer, a scene that suggests her first murder.

Character Development

Amanda Fisk: Revealed as a calculated psychopath who feels no remorse. Her exterior as a successful prosecutor and gym-goer hides a killer with six murders. She is fiercely protective of her wealth and status, willing to murder her husband to avoid losing their fortune. Her lack of empathy is shown when she hoses blood off the patio and falls asleep easily. The flashback to Don suggests a long history of violence.
Timothy Carlson: A wealthy surgeon, oblivious to his wife’s murderous intentions. His love for the Jack Russell terriers and his daily routine make him a vulnerable target. The chapter implies he had a sexual relationship with Doris Grandfelt, which would have implicated him in her murder. He is presented as a victim of Amanda’s greed and psychopathy.
Rebecca Jones: A gym acquaintance who provides exposition about the knife discovery. Her curiosity about the Grandfelt case is contrasted with Amanda’s cold indifference.
Doris Grandfelt: Though dead, her murder is the catalyst for the chapter’s tension. Her twin sister is mentioned as threatening to sue over rumors of prostitution.

Themes, Symbols, or Motifs

Psychopathy and Lack of Empathy: Amanda’s ability to kill without emotion is central. She views her husband as an obstacle to wealth, not a partner. Her reaction to Timothy’s death—washing blood, then sleeping—highlights her emotional void.
Wealth as Motivation: The chapter emphasizes the financial stakes. Amanda calculates that Timothy’s defense in a murder trial would consume their fortune, leaving her destitute. Killing him preserves the assets for her alone.
Duality / The Mask of Normalcy: Amanda maintains a professional, fit, and social appearance (Pilates, law career) while hiding a history of murder. This contrast reflects the theme of hidden evil in everyday life.
Staged Accidents: The use of the Chuckit balls and balcony to make murder look like an accident echoes a motif of manipulation and control. Amanda’s careful planning (gloves, tape, timing) mirrors her legal career.
The Gutter and the Ball Launcher: Symbols of Amanda’s domestic resentment and her ability to turn mundane objects into weapons. The gutter holds the evidence of her scheme—balls that Timothy fell for literally and figuratively.

Why This Chapter Matters

Chapter 10 is a turning point in the novel because it fully exposes Amanda Fisk as a serial killer with a specific motive: eliminating threats to her wealth while covering her tracks. It deepens the mystery of Doris Grandfelt’s murder by revealing that Timothy was involved with the victim, and that Amanda herself is the killer (having killed Grandfelt as well). The chapter provides critical backstory on Amanda’s psychology and shows her methodical nature, setting up the possibility that she will kill again. It also connects the main cold-case investigation to a new murder, raising the stakes for the protagonists (Lucas Davenport and Virgil Flowers, presumably). The chapter’s ending, with the flashback to Don, suggests her first kill, giving readers a glimpse into the origins of her psychopathy.

Study Questions and Answers

1. How does Amanda Fisk use the Jack Russell terriers and the Chuckit balls to create a plausible accident?
Amanda uses the dogs’ known behavior (chasing Chuckit balls) and Timothy’s daily routine of playing with them to stage the accident. She places balls in the gutter, then tells Timothy that the dogs rolled them there. She rigs a mop handle with a ball launcher to make it look like he was trying to retrieve them when he fell. Her careful use of gloves, tape, and her own “injury” (the knee brace) shows premeditation and attention to detail that mimics a prosecutor building a case.

2. What does the chapter reveal about the relationship between Amanda and Timothy, and how does it motivate her actions?
The marriage has been unhappy for years, held together by mutual cruelty and convenience. Amanda resents Timothy’s dogs and his morning routine. More importantly, she knows that Timothy had sexual contact with Doris Grandfelt, and if that became public, he would be charged with murder, draining their wealth. She kills him to preserve their money and avoid scandal. The lack of emotional bond makes the murder easy for her.

3. Why does the author include the flashback to “Don at the top of the stairs” at the end of the chapter?
This flashback implies that Amanda’s violent history extends further back than the six kills mentioned. It suggests Don was likely her first victim, and that she has been killing for a long time—perhaps starting before her marriage. The juxtaposition of the domestic scene (popcorn, beer) with violence reinforces her ability to hide murder behind ordinary life. It also hints at a pattern: she kills men who trust her, making her a particularly dangerous predator.
