Summary

As Chapter 39 opens, Jonas Faukman lies shivering on the cold metal floor of a van, hearing jet engines outside. He realizes his captors are involved in something far more serious than book piracy—someone powerful wants to prevent the publication of Katherine Solomon’s manuscript. Faukman’s mind drifts back to the first time he learned of that manuscript. Robert Langdon had arranged a lunch at Trattoria Dell’Arte in Manhattan, where Katherine presented her book proposal: a revolutionary model of human consciousness backed by hard science. To demonstrate that what seems impossible can become obvious with a change in perspective, she showed Faukman and Langdon a live video of two goldfish swimming in perfect unison in apparently separate bowls. She then revealed a third camera angle showing that the two feeds were actually from cameras pointed at the same single bowl. The illusion was created by a Markus Raetz statuette that read “Yes” from one angle and “No” from another. This lesson in perspective set up Katherine’s promise that her book would outline experiments suggesting human experience is far more limited than it could be. Faukman immediately committed to publishing the book. Back in the present, Buzzcut reveals that the employer—whom Faukman sarcastically calls “Darth Vader”—wants to speak to him in Prague. Faukman learns his passport has been stolen and his cat (which he doesn’t have) shot. A plane is fueling.


Key Events

  • Faukman recalls being kidnapped and feeling the van move toward a military base.
  • Flashback: Langdon invites Faukman to meet Katherine Solomon for lunch.
  • Katherine pitches a book that overturns the standard chemical model of consciousness.
  • She shows a split-screen video of two goldfish that move identically.
  • Faukman and Langdon are baffled until Katherine reveals an aerial view of a single bowl with two cameras.
  • The apparent “Yes” and “No” statuettes are actually one piece by Markus Raetz that changes appearance with rotation.
  • Katherine argues that a change in perspective makes the “impossible” obvious.
  • She promises that her book will describe experiments proving the current human experience is limited.
  • Faukman decides to publish the book immediately.
  • Return to present: Buzzcut informs Faukman they are flying to Prague, having stolen his passport and supposedly shot his cat.

Character Development

Jonas Faukman — The publisher moves from excitement about Katherine’s revolutionary ideas to genuine terror as his captors reveal their serious intentions. His initial skepticism about the goldfish illusion dissolves, demonstrating his open-mindedness, but his current vulnerability shows that his earlier enthusiasm has become a liability.

Katherine Solomon (in flashback) — Displays brilliance, scientific credibility, and a talent for making complex ideas accessible. Her charm and beauty are noted as assets for modern publishing, but her core strength is her ability to prove a paradigm-shifting claim with a simple demonstration.

Robert Langdon — Appears as a supportive friend who respects Katherine’s intellect enough to take a bet on the goldfish puzzle. His quick recognition of the Markus Raetz illusion underscores his symbologist’s eye for perspective and symbolism.

Buzzcut — The kidnapper shows a dry, cruel sense of humor (“I shot your cat”) and follows orders without revealing much about the employer, establishing him as a menacing tool of a more powerful figure.


Themes, Symbols, or Motifs

  • Illusion and Perspective — The central motif of the goldfish and the Raetz sculpture reinforces the idea that what appears separate or impossible may be a single reality viewed from a limited angle. This sets up the book’s thesis that consciousness is not confined to individual brains.
  • Suppression of Knowledge — The kidnapping plotline introduces the theme that powerful forces will go to extreme lengths to prevent new scientific paradigms from reaching the public.
  • The Power of a Single Idea — Katherine’s lunch presentation transforms Faukman from skeptic to committed publisher, showing how a well-demonstrated idea can change a person’s entire worldview.
  • Cat as Absurd Threat — The mention (and denial) of a cat being shot adds dark humor while underscoring the kidnappers’ willingness to use intimidation.

Why This Chapter Matters

Chapter 39 serves as the origin story for the central conflict: Katherine Solomon’s manuscript contains a revolutionary consciousness model that someone is desperate to destroy. By showing the publisher’s initial enthusiasm and current peril, the chapter raises the stakes from an academic debate to a life-or-death struggle. The goldfish demonstration also gives readers a concrete example of Katherine’s thinking, preparing them for the scientific explanations to come. Finally, the reveal that Faukman is being taken to Prague expands the scope of the conspiracy beyond New York.


Study Questions and Answers

  1. How does Katherine use the goldfish illusion to challenge Faukman and Langdon’s perception of reality?
    She first shows two separate video feeds that appear to show distinct fish swimming in perfect synchrony, which seems impossible. Then she reveals a third aerial camera that proves the two feeds are from cameras pointed at the same bowl, so there is only one fish. This demonstrates that a change in perspective can make an impossible phenomenon seem ordinary.

  2. What role does the Markus Raetz statuette play in the demonstration?
    The statuette appears to read “Yes” from one angle and “No” after a ninety-degree rotation, just as the two fish appear separate until the perspective shifts. It reinforces the theme that objects and situations can look contradictory depending on the viewer’s vantage point.

  3. Why does Faukman now regret his decision to publish Katherine’s book?
    He was thrilled by her ideas a year ago and eagerly agreed to publish the manuscript. But now, having been kidnapped, hog-tied, and told he is being flown to Prague—with his passport stolen and his supposed cat shot—he realizes that the same book has put him in mortal danger. His professional enthusiasm has become a personal liability.
