I killed Ramsmeat even though i knew he was innocent but i could not go any further in the investigation.

I accused Kalstien because i thought he was guilty and now hes upset. My autopsy made me think he was guilty.

Detective Raymond wants me to lure Kalstien to the tower but I cant talk to Kalstien anymore...

I think I am stuck in this game. Detective Raymond is waiting for me at the tower.

The tower is locked.

The only other plot points that I have not played with yet is the huge fight between elves and the knights in the swamp... I did not want to choose a side cause I'm a witcher. Is there any way around that?

thats the only stuff and I can think of at the moment and I dont know what to do. I do think Kalstien is evil.
