I'm part way through the mystery in Chapter 2 of the Witcher, and while I'm starting to figure things out, I can't figure out how to get Geralt on the same page as me.
I have found all the suspects and performed the autopsy. During the autopsy Geralt and Shani concluded that Kalkstein was guilty, but I don't believe that (it could've been anyone with access to alchemist poison). I've exonerated Thaler, Vivaldi, and Ramsmeat as a result, and gotten some info from them. Vincent is still listed as a potential suspect (seems like I need to exonerate him somehow also). I've discovered several clues that something is up with Raymond, but apparently not enough to convince Geralt. Now Raymond wants me to kill Ramsmeat, and my quest wants me to tell Kalkstein that I think he's guilty. I don't agree with either of these things, but I can't figure out how to advance the plot without doing them. How can I convince Geralt that Raymond is the one I should really be worried about?
