I'm in JBA HQ, I can decrypt the e-mail and get erica's code from the computer in her office, but have no idea what to do next... I know I need to get fingerprints with the scanner but where do I get them? Any help for a walkthrough of this level would be appreciated.

Basically, once you get the fingerprint(s), you have to head upstairs through the low security area, past Enrica's quarters to a panel where you will use the fingerprint to gain access to the high security area. There you will be looking to "Infiltrate The Surveillance Room" so you can gain proof of the bomb on one of the computers in there. Learning to use the 3D map on your OPSAT is, IMHO, very helpful in these situations.

Here's a "Resource Index" that points to several helpful posts.

Here's my posting that has a very extensive list of keycodes, fingerprint, personal and professional profile locations. You will have to scan through the thread to get them all since xbox.com doesn't let me edit the original post to add things found later...

You can easily google for "Splinter Cell Double Agent" walkthrough to find many of them. Gamefaqs.com has a fairly thorough version, but all of them tend to err on the side of KO's and Kills rather than total stealth.

Awesome - Thanks!
