There are at least 3 additional investigations in the upper city. Yes you have to keep searching for the invisible ink, as you will not always get the quest item when you finish. Frustrating and uses a lot of energy. I don't know if additional area's will eventually will open up. Just starting on third upper investigation. Hope that helps.
