The Climax: Who Killed Doris Grandfelt?

After two decades of frustration, the cold case of Doris Grandfelt finally breaks open when a true‑crime blogger matches a photograph of a man with a 1998 Porsche—identified as Dr. Timothy Carlson—to a knife found in a lake. The trail leads directly to Carlson’s wife, Amanda Fisk, a ruthless county prosecutor who had been dating Carlson before Doris was murdered. Fisk’s jealousy over Carlson’s relationship with Doris drove her to stalk Doris, stab her to death in a restroom, and dump the body at Shawnee Park (chapter 1). Over the following years, Fisk killed six more people, including Carlson himself, her mother, a law‑school competitor, and Don Schmidt, an accomplice who could expose her.

Lucas Davenport and Virgil Flowers present their evidence to county attorney Russ Belen. The case includes Fisk’s childhood rival Becky Watson, law‑school competitor Carly Gibson, Doris Grandfelt (the marriage competitor), Fisk’s mother, Timothy Carlson (by staging a fall with a Chuckit! ball), and the mistaken murder of Marcia Wise (a case of mistaken identity for Lara Grandfelt). The stable fire that injured Florence Nobles is also attributed to Fisk.

Fisk is indicted for first‑degree murder of Doris Grandfelt (chapter 31). She posts a $1.5 million bond using her Summit Avenue mansion and hires the real‑life Twin Cities defense attorney Earl Gray—the “one character” Sandford names in the Author’s Note as fact. Gray immediately begins undermining the prosecution: he uncovers evidence that Don Schmidt was a pedophile and a former member of a biker gang, which provides Fisk with a motive for killing Schmidt (self‑defense or revenge) and casts doubt on her entire confession narrative.

The climax is deliberately anticlimactic: no trial verdict is rendered. Prosecutor Roller estimates a 50‑50 chance of conviction, while Gray tells Fisk the odds are 60‑40 for a hung jury (chapter 31 evidence). The novel ends before the jury is empaneled, leaving the outcome ambiguous.

Major Character Outcomes

Amanda Fisk: Arrested, charged, released on bond. She retains Earl Gray and appears confident, even throwing Chuckit! balls for her Jack Russell terriers as the narrative closes.
Lara Grandfelt: Satisfied that she now knows who killed her twin sister. She orders her law firm to split the $5 million reward among contributors, with Dahlia Blair receiving $500,000. Lara plans to pursue a civil suit if Fisk is acquitted.
Lucas Davenport: Testifies before the grand jury, re‑enacts the Chuckit! ball incident with a cameraman (chapter 31 evidence), and remains involved in trial preparation.
Virgil Flowers: Marries Frankie and has his novel accepted for publication.
Dahlia Blair: The true‑crime researcher who matched the photograph; she drives home to Nebraska with $500,000 and Doris’s ashes.
Don Schmidt: Found dead in a shallow grave under his home, decapitated, head placed between legs, castrated, with handcuffs and rope. The body is the first solid physical evidence linking Fisk to a murder (chapter 30 evidence).
Timothy Carlson: Dead from an apparent accidental fall, actually pushed by Fisk after she used a Chuckit! ball to lure him over the balcony.
Marcia Wise: Killed by mistake because Fisk mistook her for Lara Grandfelt.
Florence Nobles: Injured in a stable fire set by Fisk.
Fisk’s mother: Killed with sleeping pills and an insulin overdose for inheritance.
Unresolved victims: Fisk’s earlier murders (Becky Watson, Carly Gibson, Rose McCauley) are not charged in this indictment because the statute of limitations or lack of evidence prevents prosecution.

Resolved and Unresolved Threads

Resolved:

The identity of Doris Grandfelt’s killer is confirmed: Amanda Fisk.
Don Schmidt’s disappearance is solved (he was murdered by Fisk).
Timothy Carlson’s death is revealed as homicide, not an accident.
The $5 million reward is distributed.
Fisk’s pattern as a serial killer is exposed.

Unresolved:

No trial verdict. The novel ends before conviction or acquittal, emphasizing the fragility of justice even with overwhelming circumstantial evidence.
Fisk’s other murders (Watson, Gibson, McCauley, her mother) remain unprosecuted.
The full extent of Fisk’s criminal history is known to readers and the BCA but may never see a courtroom.
The “contamination” of the investigation by true‑crime bloggers and media leaks remains a legal wild card.

Theme Resolution

Justice and Vigilantism: The justice system is shown as fallible. Lara Grandfelt uses her wealth to circumvent official channels, ultimately achieving a moral victor but not a legal one. The novel suggests that knowing the truth is not the same as punishing the guilty.
True Crime Media and Crowdsourcing: The bloggers and online sleuths successfully break the case (finding the knife, the photo), but they also leak evidence, compromise the jury pool, and force Gray to counter‑attack in the press. The tool is both miracle and curse.
Jealousy and Obsession: Fisk’s jealousy of Doris drives the murder. Lara’s obsessive 21‑year quest for justice drives the plot. Both women are consumed by their passions.
Death and Mortality: Lara’s recent breast cancer diagnosis motivates her to act before she dies. Fisk’s calm, methodical killings underscore her lack of empathy.
Class and Wealth: Lara’s millions buy the investigation (private lawyers, reward, media campaign). Fisk’s wealth buys her bond and Earl Gray. The poor would have no such options.

Epilogue (Chapter 32)

There is no separate epilogue. The final chapter (31 in numbering, but 32 in EPUB) covers:

The reward distribution and publicity.
Gray’s discovery of a retired Chicago deputy who remembers Don Schmidt as a pedophile in a biker gang.
Gray telling Fisk the odds for a hung jury are 60‑40.
Fisk retrieving two hidden Chuckit! balls from behind a mantel clock, throwing them to her dogs, and muttering, “Sixty‑forty, you little fuckers.” The image is chillingly casual, implying she is not worried.

Reasonable Interpretations

Fisk will likely walk free or get a hung jury. Gray’s strategy—attack the credibility of Don Schmidt and tie Fisk’s actions to self‑defense—creates enough reasonable doubt. The prosecution’s case is strong on motive and opportunity but weak on direct evidence.
The real‑life Earl Gray cameo reinforces the theme. By naming a real attorney who “appears in the final pages,” Sandford blurs fiction and reality, suggesting that in actual courtrooms, even a seemingly airtight case can unravel.
The open ending is the point. The book does not provide catharsis; it mirrors cold‑case realities where justice is often incomplete. Lara’s civil suit threat is the only guaranteed consequence.

6 Common Reader Questions and Answers

1. Who killed Doris Grandfelt?
Amanda Fisk stabbed Doris to death in a restroom because she was jealous of Doris dating Timothy Carlson.

2. Is Amanda Fisk convicted?
The novel ends before the trial. Roller gives a 50‑50 chance for conviction, and Earl Gray predicts a 60‑40 chance of a hung jury. No verdict is reached.

3. What happens to the $5 million reward?
Lara Grandfelt splits it among everyone who helped. Dahlia Blair, the blogger who matched the photograph, receives $500,000. Other contributors get smaller shares.

4. Why did Fisk kill her mother and so many other people?
She killed for financial gain (inheritance) and to eliminate competition (law‑school classmates, Doris). She is a remorseless serial killer who views murder as a practical tool.

5. How did Timothy Carlson really die?
Fisk lured him onto the balcony with a Chuckit! ball and made it look like an accidental fall. She later re‑enacts the scene with Lucas’s cameraman for evidence.

6. Who was Don Schmidt and why was Fisk’s killing of him a problem for the prosecution?
Don Schmidt was a former boyfriend of Fisk’s mother and an accomplice who knew her secrets. Fisk killed and castrated him. But Gray discovered Schmidt was a pedophile and ex‑biker, giving Fisk a plausible motive of self‑defense or revenge, which undermines the state’s narrative.
