i doubt if anyone can help me, but, I thought I would give it a whirl. I have followed both walkthroughs that you have on this site - pretty much to the letter - and I can't get to the back of the ministry of defense (yes, I talked to the guy in the steam bath) and I can't get to the back of Hargrove's studio. There has to be something that I am missing, but, even after starting again, I am stuck in the same place. Does anyone have an idea on what I am missing? Any help is appreciated. thanks.

Have you tried watching a video walkthrough? This is a long and pretty complex game and it's quite easy to get stumped.

There is a good one here - you would just need to figure out which part(s) of the walkthrough you need to watch.

There's also a good step by step text walkthrough HERE
