Using the Ol' Noggins

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

Description
Arno met Marie Tussaud, who tasked him with recovering the severed heads of three prominent figures.

Dialogue
Arno spoke to one of Tussaud's assistants. Arno read the letter. Arno spoke to another of the assistants. Arno spoke to another of the assistants. Arno retrieved the head of Jacques Hébert. At the Sainte-Chapelle, he stole a letter from M. Lemaitre. Arno then stole the key from LeNôtre, before infiltrating the Conciergerie. There, he recovered the heads of Olympe de Gouges and Jacques Pierre Brissot, and returned to Tussaud.
 * Tussaud: I am Madame Tussaud. I'm adept at making wax figures and death masks. I promised the Assembly I would make masks of famous victims of the guillotine. It's grisly, but it was the only way to get out of prison! And now, someone has stolen the heads I was given! Could you please find them for me?
 * Assistant 1: A friend found out something you might find important. She sent me this letter.
 * Letter: Chère Madame, I have learned that a certain politican, flushed with pride in his role over-throwing the Girondins, has procured the head of Jacques-Pierre Brissot, recently stolen from you. He works near the Conciergerie. - Your devoted friend.
 * Assistant 2: Rumor has it that a soldier who guards Sainte-Chapelle wanted the head of Olympe de Gouges. He was in love with her from afar.
 * Assistant 3: The judge at the Palais de Justice who condemned Jacques Hébert apparently wanted Hébert's head as a trophy.
 * Letter: "M. Lemaitre, I have retrieved the package. Fear not, I have hidden both our objects within the walls of the Conciergerie, each locked within a chest. I possess the single key that opens them both. --LeNôtre"
 * Tussaud: ''You have them! I can make the death masks and be safe. Oh! What a world in which we live!

Outcome
Arno recovered the heads for Tussaud, allowing her to keep her promise to the Assembly.
