I've split the recipe into two parts, the 'spyroom' part and the 'meeting room' part. Two reasons for this -
1. while I was working on this project it was helpful in keeping track of the files
2. If you're squeemish about having new objects appear in your game you can add all the collision and stuff in the meeting room without adding stuff to the spyroom. You'd have to find another way to link in though. While I was working I put a link to the meeting room in one of my test ages and travelled that way..

In order to follow the recipe you will need:
- An installation of the Complete Chronicles OFFLINE game
- PlasmaShop 3, including PrpShop http://forum.guildofwriters.com/viewtopic.php?f=86&t=2639
- The contents of the zipfile
- Nerves of steel..

STEP BY STEP
Warning! Complete the following at your own risk!
1. Backup the following files from the dat directory of your install - if anything goes wrong re-installing these files should get you home:
- spyroom_District_spyroom.prp
spyroom_District_Textures.prp
spyroom.sum
3. Right click on spyroom and choose Import.. In the file dialog that opens navigate to the folder containing the unzipped files and open the folder called 'MeetRoom', inside there are 30 files. The first file in the list should be '[plCameraBrain1_Avatar]MeetRoomCam.uof'. Click Open to import the file. Repeat this import with all the files in 'MeetRoom'
4. Once you have imported the all the contents of 'MeetRoom' you have added six objects to the meeting room and these objects now need to be added to the Scene Node. At the top of the list of folders in the filetree panel in PrpShop is one called 'Scene Node', open this and double click on 'spyroom_District_spyroom'. This will open a window containing a list of sceneobjects. Right click in the window and choose 'Add Object'. A small dialog window opens and if you scroll to the bottom of the dropdown Object list you should find our six objects:
- LinkInPointMeetRoom
MeetRoomCam
MeetRoomCamRegion
MeetRoomCollider
MtRmObjCollider
SfxRegMeetRoom
From the main File menu in PrpShop choose Save.
5. Back in PlasmaShop open 'spyroom.sum'. The easiest way to deal with the sum file is delete all the entrys - once this is done choose Save from the main File menu.
That's it, half way through!
We have now added all the objects necessary to move around in the meeting room. If you wanted to stop at this point and devise your own link everything will be waiting for you when you get there! The link is 'LinkInPointMeetRoom'
6. Now to deal with the spyroom itself. In PrpShop right click on 'spyroom', choose 'Import' and navigate to the folder called 'SpyRoom'. Inside is another list of files (34 in all). As with the previous section, import all the contents of 'SpyRoom' into 'spyroom'
7. Add 7 objects to Scene Node - ( See #4 above)
- Book05LinkPanel
DniLinkingBook05
MtRmLinkImg
NewBox01
NewBox02
RgnBook05
spyroomNewCollider
From the main File menu in PrpShop choose Save.
9. If you haven't already done so you need to deal with the sum file as in #5 above
10. Copy the 'spyroom.pak' file to the 'Python' directory in your install.
Note: Some people have had trouble with the pak file so I've included the original python files in the revised zip.
That's it all done!

I hope the above is clear..
