I'm in a worse situation than you. I enter and exit Windhelm dunno how many times, go to the graveyard at 2am dunno how many times still i cannot get the Blood on the Ice quest. Susanna the Wicked who should be dead is still alive.... Finished Stormcloaks mission by capturing Solitude... still cannot buy Hjerim... because of some problems with the house.... sighs

If your quest is broken beyond recovery and you're on PC, you can salvage by using the following console commands.
Bewarned though your house will be rather.....buggy
* Complete the quest: Type "completequest ms11" and "completequest ms11b" in your console.
* Buy the house: Type "setstage a7b33 10" in your console.
* First buy "clean up that murderer's mess" and then the rest of the home decoration or type "df492.disable" in your console.
* Clean the fog, broken glass, etc. in the house: Type "df495.disable" in your console.
* Get the Necromancer Amulet: Type "player.additem c891d 1" in your console.
I have one problem though...My necromancer amulet still says "strange amulet" and I can't get rid of it even after finishing the quest. HNNG
