Answer Key

1. B (Plot/Sequence)
Stilwell tells Simon that Deputy Quigley obtained a tip from a mainland informant about a plane smuggling drugs from Mexicali (Chapter 3).

2. C (Plot/Sequence)
While clearing the lost-and-found, Stilwell finds keys belonging to Angela Metier, a woman who disappeared four years earlier, inside an expensive Hyperlite backpack (Chapter 8).

3. C (Plot/Sequence)
Two men impersonating ICE agents present a forged federal transfer order with a Southern District seal and mismatched fonts. Deputy Mason fails to record their names (Chapter 13).

4. B (Plot/Sequence)
Stilwell freezes a KCAL 9 news segment and identifies a lightning-struck live oak in the background. The same tree appears later in excavation photos of Neary’s grave (Chapter 19).

5. D (Plot/Sequence)
While riding the elevator, Stilwell realizes Middleton was alone during his ride. The team checks the elevator ceiling escape panel and finds the abduction kit—gloves, duct tape, snap ties, a hood, ball gag, handcuffs, a knife, a garrote, and a folding shovel (Chapters 39–40).

6. B (Plot/Sequence)
Stilwell climbs an ironwood tree near the Airport in the Sky and discovers several small branches have been snapped off or cut, creating a clear view of the runway end where the shooting occurred. The reddish pulp indicates recent breaks. He finds the discarded branches in nearby chaparral (Chapter 29).

7. B (Plot/Sequence)
Stilwell visits Marquez and reveals that his grandson, Oliver the Third, confessed to chopping the vines under his grandfather’s instruction. Stilwell warns that filing an insurance claim would constitute fraud (Chapter 25).

8. B (Plot/Sequence)
Stilwell disarms Lambert, handcuffs him, and finds a plastic-wrapped derringer in Lambert’s sock—evidence of a plan to stage Stilwell’s death as suicide. He rejects Captain Corum’s offer to shred the incident report and instead calls reporter Lionel McKey to expose the conspiracy (Chapter 50).

9. B (Character Motivation)
Deputy Mason mentions Quigley transferred to Catalina to “lie low.” Stilwell later learns Quigley was involved in a divorce and an uncleared confidential informant situation. Simon calls Lambert’s claim that Quigley requested the transfer a lie (Chapters 13, 30, 35).

10. B (Character Motivation)
Ballard describes Middleton’s likely sadistic pattern, then taunts him about the garrote. Middleton lunges, hits the table face-first, breaks his nose, and screams for a lawyer—breaking his composure and ending his stonewalling (Chapter 40).

11. B (Character Motivation)
Ramirez writes on her tablet, “Trust you?” before revealing the relationship lasted five weeks, was kept secret, and only Stilwell can be trusted with the information. She withholds it from Simon and Trestle (Chapter 34).

12. C (Character Motivation)
Principal Olester Bryant identifies the tagger as Matthew Allen, the mayor’s son. Because Stilwell arrested Mayor Douglas Allen on corruption charges, he cannot contact the father before trial. Stilwell arranges a talk only, accepting Matthew’s promise to stop, to avoid any appearance of a vendetta (Chapter 32).

13. (Short Answer)
Ballard says, “I’m always going to think of you when I see that tree. Ironwood” and credits Stilwell privately with finding Middleton, stating the team is there because of him—a direct contrast to her public claim that “a girl took him down” (Chapter 40).

14. C (Theme/Symbol)
Tash explains ironwood trees share an underground root system, “hard outside but vulnerable within.” The killer buries Angela Metier beneath an ironwood, and Stilwell discovers a sniper’s perch in another ironwood. The tree symbolizes both hidden connections and concealed violence (Chapters 15–16, 29).

15. B (Theme/Symbol)
In Chapter 3, Stilwell organizes the lost-and-found to calm his nerves. Later, the backpack from the lost-and-found launches the cold case investigation. The clutter represents control amid chaos and the abandonment of people and cases that slip through institutional cracks.

16. (Short Answer)
“The dread” represents Stilwell’s persistent psychological burden—a combination of survivor’s guilt from the ambush, his fear of failure, the strain in his relationship with Tash, and the weight of unanswered questions. Its lifting signifies a moment of earned peace after recovering Angela Metier’s body and returning home to forgiveness and normalcy (Chapters 5, 17).

17. B (Theme/Symbol)
Throughout the novel, Catalina’s physical isolation mirrors the psychological isolation of characters: Stilwell’s guilt and obsession, Quigley hiding his divorce and affair, Ramirez trapped in silence, and even Middleton hiding in plain sight on the island.

18. (Synthesis)
Stilwell’s cold-case investigation provides official-sounding reasons for his movements and inquiries while he is actually probing the ambush. For example, he uses the ranger ride-along with Middleton ostensibly to retrieve search records for Angela Metier, but this simultaneously advances both investigations. His meetings with Ballard on the mainland allow him to pursue leads about Quigley’s death while Corum remains distracted by the LAPD case. The cold case also gives him a legitimate reason to study surveillance footage and crime-scene methodology, skills he directly applies to uncovering Lambert’s sniper role and Bessemer’s boat movements.

19. (Synthesis)
The ironwood tree sniper’s nest physically connects the two investigations: while searching for clues about the serial killer’s method of marking graves with distinctive trees (lightning-struck oak, ironwood), Stilwell climbs an ironwood near the airstrip and finds a cleared perch where Lambert shot Quigley. The ironwood thus represents both the killer’s psychological game—leaving markers to revisit his crimes—and the hidden conspiracy within the department. By the novel’s end, Ballard’s remark that she will “always think of you when I see that tree” ties Stilwell’s identity to the symbol of resilience, hidden connections, and justice pursued against institutional resistance (Chapters 15–16, 29, 40).

20. B (Synthesis)
Corum threatens to file a career-killing report unless Stilwell releases Lambert and accepts the cover-up. Stilwell shuts down the jail cameras, refuses Corum’s offer, and calls reporter Lionel McKey at the Catalina Call. His choice demonstrates that moral integrity and loyalty to his fallen deputies outweigh self-preservation, even at the cost of his island life (Chapters 47, 50).
