Summary
Reinhold von Rumpel searches a château outside Amiens, the home of a retired paleontologist. He believes the museum’s chief of security fled here three years earlier with the Sea of Flames. Inside a library, a safecracker opens a hidden strongbox. Among old certificates and coins, von Rumpel finds a velvet box containing a blue pear-cut diamond. Briefly he sees a red heart flicker inside the stone, but when he examines it under a lamp the hope collapses—it is another fake, the work of Dupont. This is the third counterfeit he has uncovered. The war is turning against Germany, and his cancer is worsening. Von Rumpel remembers the museum’s extraordinary jewel safe, a puzzle box only one person could have designed. He wonders who the third courier might be, unable to abandon his hunt.
Key Events
- Von Rumpel enters a château outside Amiens and locates a hidden strongbox in a library.
- A Gestapo safecracker opens the strongbox, revealing a velvet box with a blue pear-cut diamond.
- Von Rumpel briefly sees a red heart in the stone, then confirms it is a third fake by Dupont.

- He recalls the museum’s jewel safe and speculates about who the third courier of the real diamond might be.
Character Development
Reinhold von Rumpel is consumed by a compulsive search he cannot abandon despite mounting evidence of failure. His awareness that the war is lost and his cancer is spreading deepens his desperation. He clings to the belief that keeping the stone grants immortality, yet his physical and mental burden is crushing. The chapter shows von Rumpel’s transition from a confident Nazi art thief to a man cornered by time and circumstance.
Themes, Symbols, or Motifs
- Illusion vs. Reality: The fake diamonds, all crafted by Dupont, highlight how easily hopes can be deceived. The flickering red heart that von Rumpel sees suggests his own wishful thinking.
- Fate and Desperation: Von Rumpel’s refusal to give up despite clear odds mirrors his notion that the diamond controls destiny. The chapter emphasizes how obsession overrides rational thought.
- The Sea of Flames: Though absent physically, the real diamond exerts power as a legend. The memory of the museum safe reinforces its mystique as a puzzle only a brilliant mind could devise.
- Decay and Collapse: The war’s downturn, von Rumpel’s illness, and the fake stones all symbolize the crumbling Nazi enterprise and his own failing body.
Why This Chapter Matters
This chapter is a turning point for the subplot of the diamond hunt. Von Rumpel has now exhausted all three false trails, leaving him with no leads but the shadow of the museum’s safe. It raises the question of who the real courier is and why the chief of security fled with a fake. The narrowing of possibilities increases tension as the stories of Marie-Laure and Werner near convergence. Von Rumpel’s physical decline and the war’s reversal remind the reader that time is running out for everyone.
Study Questions and Answers
1. Why does von Rumpel decide that the diamond he finds is a fake, and what does this realization cost him?
Von Rumpel examines the stone under a lamp and sees no consistent red heart; the flicker he glimpsed earlier was a trick of light. The discovery costs him his last hope—his “luck” is spent, and he admits the third fake means he may never find the real Sea of Flames.
2. How does von Rumpel’s memory of the museum jewel safe contribute to this chapter?
He recalls the safe as a unique puzzle box, implying only one person—likely the museum locksmith—could have designed it. This memory suggests he suspects the trail leads back to the museum’s master craftsman, but he does not yet know who that is.
3. What does this chapter reveal about von Rumpel’s internal state as the war nears its end?
The chapter shows him physically weakened by his tumor and emotionally drained by repeated failures. He feels the war collapsing around him but cannot stop; the diamond’s legend of immortality keeps him obsessively searching despite rational evidence that he should give up.
