Quest \"Antidote\". (Vampyr)

The problem with the search as the title of Jeffrey McCallum at the cemetery, to obtain from him a drop of blood of king Arthur. Searched the whole cemetery and all the surroundings around him, he's nowhere.
Watched the passage, he should be right in the center of the cemetery, but I don't have it, whatever I did, wherever I went.
Who knows what kind of trouble? MB someone knows her decision
