In Amiens, von Rumpel tracks down a third stone that looks like the Sea of Flames. To his dismay, the stone turns out to be another fake—he has yet to find the real gem. He thinks more and more about what he’s read about the diamond—whoever owns it will live forever. He also thinks back to the safe at the museum—it was beautiful, and designed almost like a puzzle box. He wonders who could have designed it.
At this point, it’s only a matter of time before von Rumpel figures out the truth and heads to Saint-Malo. It’s ironic that it is actually Daniel’s cleverness and skill at disguising things that ultimately gives him away.
