Eva is in the final moments of her mission. She can prevent a terrible disaster but she's running out of ideas. She thinks the book holds the answers but it is empty.

Eva has 18,000 points and she knows that the French Republic is in danger. She does a back-up and clears level five.

Time is running out.

Eva gets into Ratava's headquarters and overhears members of an imperialist cult making plans to send France back to the Second Empire. Eva holds the code they need to transform history.

Eva searches the bookstore in vain for an author named Ratava. She meets Yvan's twin brother and he gives her a book by RATAVA publications. Eva finds the publisher's address.

Eva tells him Yvan was murdered by the Man in the Black Hat. She asks Louis if the word RATAVA means anything to him. He gives her a book from a publisher called RATAVA entitled the "The Butterfly Effect or How to Change History." Who would want that?

The latest twist in the plot is that Eva has to try to decipher the word RATAVA. She heads for the address that might help her -- the bookshop mentioned by Yvan before he was murdered. Will she meet the same fate there?Eva and the player recap and realize that they haven't been to the bookshop in Rue St Sabin. Maybe that's where they will find out what RATAVA means. Eva asks Edmond to take her to the bookshop but when he offers to go in with her, she declines. He tells her to be careful, as it might be dangerous. Does he know more than she does?

She gets inside the tomb using the phrase “La statue domine le mort, mais la fertilité est retrouvée.” Then she goes down some steps and, after completing level four, she wins a tool allowing her to cancel a game over. While looking around in the crypt she notices the letters RATAVA. Another riddle has to be solved.

Eva finally finds out what the mysterious message means. But the riddle of the code 1-8-5-2 hasn't been solved. Time is running out and she's still at the cemetery. Will she take the code to the grave with her?Eva asks the guide about the phrase, "La statue domine le mort, mais la fertilité est retrouvée." She asks Eva if she wants children. The guide explains that the phrase could refer to the tomb of Victor Noir, said to have the power to restore fertility. Eva and Adrien leave the tour to visit Noir's tomb. One riddle has been solved. That's good, but not enough.

Edmond finally arrives at the last possible minute to take her and Adrien off to Père-Lachaise. But why was Edmond so late?
