Summary
Stilwell arrives at the substation to find Ahearn in borrowed clothes and furious about an Instagram photo of his rescue. Ahearn belittles the substation and refuses to let go of the grudge stemming from Stilwell’s earlier complaint, which blocked his promotion. Stilwell offers to cooperate but is warned not to work the homicide case. After Ahearn leaves, Stilwell shares a moment with Mercy, acknowledging that his transfer may have been a fortunate turn. He finds his lockbox has been tampered with—someone tried to retrieve the saw handle he stowed there. Calling on Mercy’s local contacts, he obtains Henry Gaston’s number and phones him, accusing Gaston of the attempted theft. Gaston denies it but inadvertently admits he fears being labeled a snitch. Stilwell gives him until Wednesday to come in. He then visits the harbormaster’s tower and asks Tash for a list of boats that were in the harbor during the likely window of the victim’s submersion, revealing his persistence despite no longer being a homicide detective.

Character Development
- Stilwell: Demonstrates resilience and a capacity for finding value in an unwanted assignment. He refuses to let Ahearn’s hostility rattle him and takes proactive steps to advance the case, such as contacting Gaston and gathering harbor records. His willingness to use local knowledge (Mercy’s card boxes) shows adaptability.
- Ahearn: Remains bitter and petty, clinging to a grudge that undermines his professionalism. His behavior contrasts with Stilwell’s composure, highlighting Ahearn’s immaturity.
- Mercy: Provides quiet support and proves an invaluable resource through her community contacts. Her assessment of Ahearn as “pathetic” aligns her with Stilwell’s perspective.
- Henry Gaston: Avoids accountability but reveals his fear of being seen as an informant, suggesting he has more at stake than a simple theft.
Themes, Symbols, and Motifs
- Grudges and Moving On: The chapter contrasts Ahearn’s obsessive grudge with Stilwell’s ability to move forward and find purpose in his new role.
- Local Knowledge vs. Official Authority: Stilwell leverages Mercy’s informal records and the harbormaster’s logs, undermining the idea that the official homicide team has a monopoly on investigative leads.
- The Saw Handle as Evidence: The tampered lockbox and Stilwell’s strategic deadline make the saw handle a symbol of unresolved truth and the power of physical evidence.
- Water and Depth: Stilwell’s reflection on underwater recovery as “peaceful” suggests his comfort with the hidden, dark aspects of his work—an attitude that serves him in this case.
Why This Chapter Matters
Chapter 6 deepens the conflict between Stilwell and Ahearn while showing Stilwell’s resilience in the face of demotion. It also advances two investigative threads: the potential connection of Henry Gaston to the saw handle and the new lead that the victim may have come from a boat that left the harbor. The chapter cements Stilwell’s determination to work the case indirectly, even without formal jurisdiction.
Study Questions and Answers
1. How does Stilwell’s reaction to Ahearn’s hostility reflect his character growth?
Stilwell does not retaliate; instead, he offers cooperation and keeps his focus on the case. This shows he has moved past the bitterness that might have consumed him earlier, embracing his new position and finding value in it.
2. Why does Stilwell give Henry Gaston until Wednesday to come in voluntarily?
Stilwell uses the deadline to pressure Gaston while keeping the saw handle out of reach. By holding the evidence at the sub, he maintains leverage and gives Gaston a chance to cooperate before escalating the matter to official channels.
3. What does Stilwell’s request for harbor records reveal about his approach to the investigation?
Even though he is officially off the homicide case, Stilwell continues to gather information. Relying on local sources like Tash and Mercy, he demonstrates that unofficial networks can be as valuable as formal authority in solving a crime.
