Jack McEvoy: The Writer Who Helped Expose Tidalwaiv

Overview

Jack McEvoy is a veteran investigative writer who enters The Proving Ground as an outsider with a deep track record of exposing technology‑related dangers. He is the author of three bestselling nonfiction books—The Poet (about the dark side of the internet), The Scarecrow (data mining), and Fair Warning (unregulated DNA testing)—and he runs the Substack column Fair Warning, which focuses on the follies of artificial intelligence and consumer protection.

McEvoy is in his early fifties, described as looking like “an aging surfer” with a full head of brown‑going‑gray hair. He carries himself with a direct, confident manner—firm handshake, steady eye contact—and presents himself not as a typical journalist but as a writer who wants to embed himself inside a story that “encapsulates everything” about generative AI.

Plot Role in The Proving Ground

McEvoy first appears in Chapter 3, approaching Mickey Haller after a preliminary hearing in the civil case Randolph v. Tidalwaiv Technologies. He proposes a mutually beneficial arrangement: he will work for Haller’s team without pay, offering his research expertise and Silicon Valley connections in exchange for inside access to write a book (and possibly a Substack and a podcast) about the case.

After a background check confirms McEvoy’s integrity—Cisco learns he once spent 63 days in jail for protecting a source—Haller brings him into the team. McEvoy signs a nondisclosure agreement, a declaration of non‑involvement with Tidalwaiv, and a manuscript‑review clause. He then begins working inside the Faraday cage where discovery materials are stored, helping Lorna Taylor sift through redacted documents.

McEvoy’s key discovery: using his professional online network TheUncannyValley, he identifies a pattern of redacted email addresses that leads to Naomi Kitchens, a former Tidalwaiv ethicist whose name had been scrubbed from all discovery materials. This breakthrough sends Haller and McEvoy to Stanford, where they recruit Kitchens (code‑named “Challenger”) to provide internal ethics reports and a “smoking‑gun” email.

Later, McEvoy helps devise the risky plan to access Aaron Colton’s AI companion Wren from inside the Van Nuys police station. He also researches a coder named Nathan Whittaker, linking his Reddit alias wiseacre23 to incel ideology—evidence that becomes central to Haller’s “rotten‑apple” trial strategy. In the final chapters, McEvoy is appointed director of the Rebecca Randolph Center for Technological Oversight, the foundation that Brenda Randolph creates with the settlement money.

Motivations and Traits Shown Through Actions

McEvoy is driven by a commitment to truth‑telling and accountability. He does not seek payment for his work, telling Haller, “Just let me inside the wire.” His willingness to sign a manuscript‑review clause—after initial hesitation—shows he understands the need for legal safeguards while still preserving his journalistic core. When Haller points out the irony of making McEvoy sign an NDA (given Haller’s own courtroom attacks on corporate NDAs), McEvoy signs anyway, acknowledging the practical necessity.

His patience and methodical nature are evident in the cage: he works alongside Lorna for days, combing through terabytes of data until he spots the redacted email pattern. His use of a niche professional network, TheUncannyValley, demonstrates that he maintains connections from his years of reporting, connections that Haller and Cisco lack.

McEvoy also shows emotional intelligence and restraint. When he leads the interview with Naomi Kitchens in Palo Alto, he lets her speak freely and respects her initial refusal to violate her own NDA. He does not push; instead, he allows Haller to argue the legal and moral case for cooperation.

Relationships

  • Mickey Haller: From initial caution to deep trust. Haller values McEvoy’s expertise and relies on him to navigate the technical discovery. They develop a natural rapport; Haller describes the handshake as “the start of a good thing.” McEvoy respects Haller’s courtroom instincts, while Haller admires McEvoy’s investigative patience.
  • Cisco and Lorna: Cisco is initially skeptical (“it was obvious … Cisco wasn’t convinced we needed McEvoy”), but McEvoy earns his place through diligent work. Lorna works side‑by‑side with him in the cage and appears to accept him as a teammate.
  • Brenda Randolph: She thanks McEvoy publicly after the settlement and personally appoints him to lead the foundation, recognizing his integral role in the victory.
  • Naomi Kitchens: McEvoy treats her as a source to be protected, not exploited. He advocates for Haller to arrange security for Kitchens’s daughter after threats.

Key Decisions and Consequences

  • Deciding to approach Haller: Instead of writing about the case from the outside, McEvoy seeks direct involvement. This gives him unprecedented access but ties his publishing timeline to the trial’s conclusion.
  • Signing the NDA and manuscript clause: He gives up the ability to publish anything before a verdict or settlement, limiting his immediate income but securing a front‑row seat to the most consequential AI liability case in the country.
  • Using TheUncannyValley network: This single action uncovers the hidden witness (Kitchens) and the evidence that eventually forces Tidalwaiv to settle.
  • Agreeing to lead the interview with Kitchens: Haller trusts him to conduct a sensitive conversation, and McEvoy’s respectful approach helps keep Kitchens on the team even after she later wavers.
  • Pivoting to the coder strategy: McEvoy’s research on Nathan Whittaker’s Reddit history leads Haller to change his final witness, which becomes the critical piece in winning the case.

Theme and Symbol Connections

AI Liability and Ethics: McEvoy’s Substack Fair Warning directly embodies the theme of corporate accountability for AI harms. He helps prove that Tidalwaiv knowingly deployed a dangerous product. Redemption and Justice: While the story belongs primarily to Brenda Randolph and Haller, McEvoy also experiences a form of professional redemption. He has been writing about technology dangers for years but never had a case that so perfectly validated his warnings. The trial gives his work tangible impact. Witness Intimidation and Protection: McEvoy is part of the effort to protect Kitchens and her daughter, and he himself operates under a strict NDA—a mirror of the corporate NDAs Haller fights in court. The irony underscores how legal tools can be used for both good and ill. Corporate Accountability: McEvoy’s uncovering of the hidden emails and his role in the press conference (where the corporate apology is read) cement the theme of public accountability. Grief and Family Bonds: McEvoy does not have a direct personal stake in the grief of the families, but his decision to become director of the Rebecca Randolph Center suggests he adopts the mission of turning tragedy into preventive action.

Book‑Specific Questions and Answers

1. Why does Jack McEvoy approach Mickey Haller in the courthouse hallway?
McEvoy wants to propose a mutually beneficial arrangement: he will offer his research expertise and technology‑industry contacts to help Haller’s case, and in exchange he will gain inside access to write a book and Substack columns about the trial.

2. What is the significance of the three documents McEvoy signs?
The nondisclosure agreement, the declaration of non‑involvement with Tidalwaiv, and the manuscript‑review clause protect Haller’s attorney‑client privilege, ensure McEvoy is not a double agent, and give Haller editorial control until after the case concludes. McEvoy initially objects to the manuscript review but signs after Haller insists.

3. How does McEvoy uncover the identity of Naomi Kitchens?
While reviewing redacted discovery documents in the Faraday cage, McEvoy notices a pattern in the redacted email addresses. He uses his professional network, TheUncannyValley, to cross‑reference the email patterns and identifies Kitchens as the person whose name had been systematically scrubbed from all materials.

4. What role does McEvoy play in the trial’s final witness strategy?
McEvoy’s research reveals that programmer Nathan Whittaker posted on Reddit as wiseacre23 and that his incel ideology corrupted the Project Clair AI. This evidence leads Haller to drop his original final witness and instead put Whittaker on the stand as a hostile witness to prove the “rotten‑apple” theory of liability.

5. What happens to McEvoy after the settlement is announced?
Brenda Randolph announces the creation of the Rebecca Randolph Center for Technological Oversight and names Jack McEvoy as its director. His role as a writer transitions into that of an advocate and watchdog, ensuring that the lessons from the case are applied to prevent future AI‑related tragedies.
