If you finish the quest of unlocking the basement door using key, when you talk to "Hesperia" and ask her about the "Screaming Hall" she will give you another "gleaming marble" and the main quest progress of "Screaming Hall" investigation restarted. Also when you already possessed the "Sacred Amulet" but you talk again with the ghost in front of "Village's Chief" and start the dialog about give him services in exchange for item, he gave you another "Broken Amulet(R)" again. Perhaps you would like to check on this
