French Crown Jewels (memory)

Encyclopédie Diderot was a virtual representation of one of Arno Dorian's genetic memories, relived by a Helix initiate through the Helix Navigator.

Description
Arno tracked down the last three of the French Crown Jewels.

Dialogue
Arno found Lefrançois. Arno chased the first thief. He recovered the first diamond and a note from the thief. Arno found the other two thieves at the border post and recovered the diamonds from them. He then returned to the manager.
 * Manager: There's no end to it! We managed to recover the stolen Crown Jewels, now we find three prominent gems are still missing! And one of those is the French Blue itself! The jeweler Lefrançois has a shop near Halle aux Grains. It's possible the thieves tried to sell the gems to him.
 * Lefrançois: As a matter of fact, there was a man who came in here with an impressive diamond. I refused to have anything to do with it. Ever since, he's been lurking in an alley nearby and badgering my customers.
 * Bernard: I didn't take anything!
 * Note: "Bernard, if you can't sell your diamond, come join me at the border. We'll smuggle them out and sell them in . I'm waiting at the Barrière des Martyrs border post."
 * Manager: Ah, the diamonds! I will see that they are safely returned to the National Convention.

Outcome
Arno recovered the last three Crown Jewels.
