One of them was about a young woman who was a Detective who was called to a small city to investigate the deaths of several people and yet when it came time to see the bodies, she could not find them and all of the info led back to a Priest who did not have any idea of what she was referring to. A couple more deaths occured and they also led back to the priest. I, at first, thought that the Priest had something to do with the deaths but I do remember that in the end that he knew of a legend about the deaths and disappearances which in turn helped her to find the true answer. Does that info "ring a bell" with you at all?
The other game was about a young girl going to a foreign country to find her grandfather and the info she gathered led her into a bunch of caves where she ended up meeting a guy that also had ties to her grandfather and they ran into a man who they had to kill because he tried killing them so that they could go no further. She finally was able to find her grandfather but he had died but he had left her with a fortune of beautiful artifacts. This one may sound "poorly done" but it wasn't and I used to play it quite often.
I was thinking the first one sounded like a Strange Cases game, but I never played any of those except the demos.
Anyone have any ideas?
