First, absolutely loving this game. One of the best games on here. I'm so stuck though, and I've searched the crap out of this thread and can't find the solution (though I did find 2 people saying they had the exact same problem and then saying "nevermind, figured it out" without saying what the answer was. Dammit!)
I've interrogated Eve and Miriam and recruited them. I've completed the crypt. But I can't interrogate Teresa and Delilah.
I've done the plant the camera and get the evidence from it thing. I've seen the scene about the Black Pearl of Pelasso, but I haven't been able to learn what that was anywhere. (I saw some references in this thread to it mentioning a casino part you can't do yet, but I didn't even see this, so I'm sure whereever you get this mentioned is something I need to do).
As for Delilah her notebook page is filled out except for what the last question is. All the clues are filled out on the clue page. It just feels like I'm missing clicking on a pixel somewhere with no hints as to where these pixels are.
Thanks to anyone that can help. I've literally spent over an hour searching this thread and been unable to find the answer (and probably more time in game trying to find it)
