chorrol castle investigation help

Canvas the Castle

To begin this one, you have to speak to Countess Valga of Castle Chorrol
when you've sufficiently buttered her up. Ask about the "Investigation."
You'll learn that someone has stolen the only painting of her beloved Count, now
deceased. She asks you to find out who it is, but NOT to accuse the wrong
person. Also, she gives you keys to the Private Areas of Chorrol Castle. Ooh,
my hands are itching.

Anyway, you're to question some residents of Castle Chorrol. Follow the
arrows on the map and talk to each. Basically, they tell you that Orgnolf and
Chanel were seen in the West Tower doing various things. After you talk to all
of them, it'll tell you to look for clues.

Hmm...West Tower, that might be significant. Head over to it and enter
the basement level of it. Behind the stack of crates you'll see a paitning of
the Chapel. Activate it and it'll give you a dialogue about someone in the
castle being a painter. You're to look for more clues. It's either Orgnolf or
Chanel, so search both of their rooms.

In Chanel's room you'll find a podium thingy with a chair leaning on it.
Activate it to find some painting supplies. Another dialogue asking for more
clues. Continue searching.

This part frustrated the hell out of me. I eventually looked online
(can't remember where, so, unfortunately, I can't give proper credit) and
someone said to look in the Dining Hall carpet. There will be paint stains on
it, which you activate. You now have enough evidence to accuse Chanel.

Go to Chanel and talk to her about "Accuse"-ing her. Depending on her
disposition (over 70 I think), she'll tell you the real reason for stealing the
painting. After you talk to Chanel, head to the Countess.

Now you have 2 choices:

1.) Tell the Countess about Chanel. She banishes Chanel from the castle, but
gives you 300 gold and some expensive trinkets.
2.) Tell the Countess that neither did it. She'll give you 50 gold for your
trouble. Talk to Chanel again and she'll reward your mercy by making you
a painting - but it'll be done in 3 weeks.
