After persuading her that she wants to find the truth and help, Imelda allows Nico to access Carchon's room, which contains an elephant carving exactly the same as that of Nico's father and a stone cylinder, which contains a hidden code of letters. On Carchon's corpse, Nico discovers a ticket stamped "Bateaux de la Conciergerie" and goes to investigate the dock. By using the letters on the cylinder, she discovers a secret office area where Carchon and many others met for business. After writing her story up and publishing it, her editor tells her to drop the story at which Nico becomes angry. However, she receives a mysterious phone call from a man called Plantard who tells her he needs to speak to her about her story.
