i think i found the head in a corridor..

I have fiddled with various camera angles and zoom for about half an hour there. It really made me mad that I will have an unfinishable quest in my quest log for the whole rest of the game, so I really tried. No luck.
Btw, the head is placed randomly in the castle. Every time you start a new game, it will be elsewhere. But of course, I don't want to start a new game, since I am quite far already.
