Nightshade Chapter 13: Watching the Water

Spoiler Notice

This chapter reveals Stilwell’s independent investigation into the Black Marlin Club. It contains details about the night Leigh-Anne Moss was fired and introduces a potential lead involving a workboat and the yacht Emerald Sea.

Summary

Stilwell eats a cold enchilada at the harbormaster’s tower while Tash sets up eight harbor camera feeds. He tells Tash he is looking for boat activity from the weekend before last, claiming an interest in a reported sculpture theft from the Black Marlin Club. She offers to compile a list of club members and mooring users. Stilwell begins reviewing video from four cameras covering the club’s dock and mooring buoys. He watches at 12x speed for several hours. At 3:13 AM on Sunday, he spots a small workboat emerge from the club’s covered dock, disappear between a ketch and a large yacht, and then reappear 25 minutes later. Tash identifies the ketch as the Emerald Sea, owned by Mason Colbrink, a retired corporate lawyer who often leaves his boat at the mooring. The yacht is left for later identification. Stilwell learns that the Emerald Sea left the harbor the day before. Tash checks Colbrink’s comings and goings. Stilwell feels uneasy involving Tash in the investigation, recalling the danger faced by an amateur sleuth in Los Angeles.

Character Development

Stilwell: Shows determination by spending hours watching video. He remains cautious about his secret investigation, deflecting Tash’s curiosity about the sculpture theft. His protective instincts surface when he worries about Tash’s safety.
Tash: Enthusiastic about being part of an investigation, she quickly provides practical help and local knowledge. Her cooperative nature contrasts with Stilwell’s guarded approach.
Mason Colbrink (introduced indirectly): Described as a retired corporate lawyer who owns a large ketch and who checks in with the harbor, yet leaves his boat moored for long periods. This suggests wealth and a possible connection to the club’s elite.

Themes, Symbols, or Motifs

Surveillance and Hidden Truths: Stilwell uses harbor cameras to uncover activity invisible to the naked eye. The grainy, time-lapsed footage symbolizes the difficulty of discerning truth from routine events.
Class and Privilege: Tash’s comment about members who think they are above the rules points to the power dynamics in the harbor community. Colbrink’s ability to leave his boat for weeks despite “active boating” rules illustrates how wealth bends regulations.
Secrecy and Trust: Stilwell conceals his true investigation from Tash, while Tash openly shares information. The tension between honesty and protection mirrors Stilwell’s earlier relationship dynamic with her.

Why This Chapter Matters

Chapter 13 marks a turning point in Stilwell’s unofficial case. The workboat sighting at 3:13 AM provides the first concrete clue that something unusual occurred the night after Leigh-Anne Moss was fired. By linking the boat to the Emerald Sea and its owner Mason Colbrink, the chapter introduces a potential suspect—or a witness—connected to the club. Stilwell’s decision to bypass official channels by using harbor resources also raises the stakes of his rogue investigation. The chapter reinforces the tension between his personal and professional relationships, especially with Tash, and foreshadows the danger that amateur sleuthing can bring.

Study Questions

What does the timing of the workboat’s appearance (3:13 AM on Sunday) suggest about the incident Stilwell is investigating?
Answer: The early-morning hour implies that the activity was deliberate and likely covert. It occurred both after the club’s regular hours and after the weekend when Moss was fired. Stilwell considers it suspicious enough to slow the playback and investigate further.
Why does Tash believe Mason Colbrink “checks in” with the harbor, and what does this reveal about the owner of the Emerald Sea?
Answer: Tash explains that Colbrink checks in to justify leaving his boat moored for weeks, since the harbor requires active use. This reveals that Colbrink is aware of the rules but uses his status and cooperation to bend them—a pattern common among wealthy members of the Black Marlin Club.
How does Stilwell’s reaction to Tash’s enthusiasm for the investigation reflect his own past experiences?
Answer: Stilwell remembers a story about an amateur sleuth in Los Angeles who was shot dead in her home office. His discomfort shows he knows police work carries real danger, and he does not want Tash to become involved in a case he is handling unofficially.
