I am stuck at the quest "Blood on the Ice". What I have done so far:
- I arrived at Windhelm and picked up the quest from the guard standing near the three witnesses and the body.
- I spoke with the witnesses.
- I spoke to Jorleif.
- I spoke to Helgrid.
- I followed the blood trail to Hjerim.
- I got the key to Hjerim from Friga Shatter-Shield after speaking with a guard for access.
- I investigated the chest, the shelf, the wardrobe and the altar and took and read the eleven letters and the two Butcher's journals, and took the amulet.
At this point, according to the walkthrough on UESPWiki, I should be able to show the amulet and the journal to Jorleif and to speak with Viola Giordano and Calixto Corrium. But that does not happen. The quest progress is still showing to "Look for clues" and neither Jorleif nor the other two have a conversation option regarding the quest.
I also reloaded the game to a point when I already spoke with the witnesses but not already to Jorleif, but that did not change anything.
So, does somebody know any help how I can progress?
