Guild Wars 2 – A Society Function

Head over to the Rurikton Quarter and to Minister's party. As you enter, after having some words with with Countess Anise:
Countess Anise: “This will be delightful. Having the hero of Shaemore on my arm will make tongues wag.”
Hero: “Thank you for letting me join you this evening, Countess.”
Anise: “I'm always willing to do what I can for queen and country. That being said, let me offer some unsolicited advice. First, mingle. Speak to everyone. You never know how will say something they'll regret later. Second don't limit your conversations to nobility. Servants and guards see everything.
Hero: “Understood. I suppose it goes without saying that I should be discreet.”
Anise: “You catch on fast. Go and charm the masses. You now where to find me if you need me, pet.”

Evidence #1
Head Southwest into the house itself. Go in and turn to the right, toward the courtyard. You will find Lord Faren there:
Faren: “There my heroic friend! Say, could you hold off on the acts of valor for a bit? Makes it hard to strike up a conversation with a pretty lass when she only wants to talk about you!
Hero: I'd never knowingly stand in the way of you conquests.”
Faren: “Ah! 'Burn me,” as the charr say. I have some interesting information for you! But I need a small favor first. Please?
Hero: “What is it?” (Feel free to choose the Charm, Dignity or Ferocious Option if you like it).
Faren: “I've been dying to speak with Baroness Jermina all night, but she keeps talking about you and won't believe we're friends! Can you believe that! Would you put in a good word for me?”
Hero: “All right. If it'll get me the information you have, I'll do it.” (Feel free to choose the Charm, Dignity or Ferocious Option if you like it).

Head out into the courtyard just through the door behind Faren. Talk with the Baroness. There seems to be no bad way to go through this conversation as the Hero will plug Faren plenty on their own. Feel free to talk of him as you would enjoy to. He does invite some insults but he does seem to have a good heart at his core. Now return to Faren, having talked with the Baroness. He will reward you with your first piece of evidence.

Evidence #2
Now head up the stairs to the Southwest. You will find the Lady Madeline on the first landing talking with someone, Lord Benjamin. He asserts that she knows how her brother's mind works. She begs off as she has been occupied taking care of her mother. Once the two have finished talking is when you can jump in and ask a few questions. From this she reveals that she saw her brother give a person some papers. Further more she mentions that he left packages at their country estate for suspicious characters. She will agree to testify in court against her brother to prevent anything more falling upon their house or ruining their Mother's health more.

Evidence #3
Head to the North and take the stairs up to the next floor. As you step out you will be called over by Ministry Guard Reth. You can talk with him some, asking a few good questions. He clearly known something and will tell it to you in exchange for a drink from the ground floor. Head back down the stairs. Go to any of the appetizer plates that are nearby the stairs you will be able to get a drink for Reth. Grab it and take it back up stairs. Reth will reveal that the orders they receive to move the guards come from Minister Zamon directly. He feels as though he is taking a huge risk and is hoping you will put this information to good use.

With all the evidence you need it is time to head back to Anise. Just go back down the stairs and to the Northeast. You will find her just next to Logan Thackeray. Talk with them to move things forward. They will have Zamom arrested as he appears at the party. After that, it is off to the Ministry to start the ending of this story line.
