The murder quest went strange at the end:
In the Black Cult cave, after I found the zombie Jake the quest log claimed that I had beaten Evelyn, even though she was not there. When I subsequently went back to town she was still standing in the doctor's house: the doctor would say how awful it was what she had done, but talking to her gave no options to do anything about her. Attacking her just gets the doctor and several guards coming to her rescue.
