Either way, when you enter the dining room, the tour group will leave as long as you've completed the day's tasks.

Poussin's Tomb
After entering the dining room, Grace will be whisked off with the tour group. The first stop is Poussin's Tomb. Watch the cutscene of Madeline's lecture. Once she's finished, she'll indicate that you can walk around, observe different things, and take photographs if you have a camera. Use the mouse and examine the various structures in the area. Take special note of Emilio Baza, who is doodling something in the dirt - it appears like he's writing the word "SUM." Open your inventory and select Grace's sketchpad. Use the sketchpad on the word so Grace will jot it down for future reference.

Examine the word that Emilio Baza is scribbling in the dirt.

Top of C de. Blanchefort
After the first stop, you'll be whisked off to the second destination, the top of Blanchefort. Watch and listen to the lecture given by Madeline. When it's finished, walk over to Madeline and Wilkes, who are engaged in conversation. Grace will approach closely, but stand back and listen in on their dialogue.

Once you've overheard Buthane and Wilkes' conversation, walk over to Lady Howard and Estelle and do the same thing. Get close to them, and you'll automatically begin listening to their conversation. As you do, Lady Howard and Estelle will mention Le Serpent Rouge. When they do, the rest of the group will walk over and ask them about Le Serpent Rouge.

Walk near Lady Howard and Estelle to overhear them talking about Le Serpent Rouge.

After this sequence, you're free once again to speak with the other characters. Talk with each character and save Mosely for last. Talk with Madeline especially about Le Serpent Rogue. When you're finished talking to the others, walk over to Mosely and begin a conversation. Exhaust all the dialogue topics, specifically about the treasure. Once you're finished talking with Mosely, the time block ends.
