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. But what is expecting her there?There's no trace of RATAVA at the bookshop. Eva is stunned when she sees an elderly man who looks like Yvan. It's his brother Louis. 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?
