How do I get the chalice? Looked all over for a switch or other mechanism, but no luck.

I love this mission, but I'm at a point where I cannot proceed. I have well over 6K loot, I've taken care of Poor Martha, I've uncovered 7 secrets, been in the rooms below Martha, nobody is left standing so I can run around unhindered while I use my lantern. But still I have no idea what to do next. I must have missed one small thing that's preventing me from going forward. A few rooms are still locked: 1. The Interrogation room I keep hearing about. Is it one of the two barred doors? If so, how do I get in there? 2, There's a spider room? Where is that? 3. There's a locked room near the office on the top floor. I have no key for it. 4. Also, the front page of this mission as it's loading show a room with spider webs. I have not found that room yet, either. I have evidence, but apparently not enough. Obviously this will be in the rooms I have yet to access. Oh, and I haven't begun to work out how to get the Heart. I could use a few spoilers, since I'm starting to get bored after a few hours of fruitless running around.

Great mission. On my own I found only 8 secrets. I keep seeing reference to the and I haven't found it. I've found a but can't find the corresponding secret. I've found a but can't find the corresponding secret Any clues for me?

Wow. Every time I think I'm done in this mission I see something new. I think I must still have lots of loot to find....
