I've finally reached a stumbling block I can't seem to get beyond. For the life of me, I can't locate the fourth painting in the church to activate the secret door. I've even had my wife look (much to her annoyance) thinking I was missing something obvious. No avail. Any help?
Did you get the one behind the locked gate there? If the top of the screen is North, there is a painting on the North wall of each alcove (the gated one, and the one opposite it), then one each on the East and West sides flanking the altar.
