Has neone else notive that the diary room has an extra bit on it on the map on the channel 4 site, ie its not just a square room. looks like it could b another enterance

Yeh I noticed that. Science thinks there's another door behind the glass - could be why they used lots of mirrors, to hide the door easily.

that is exactly what i was thinking mirror panels would b easier to change than a solid wall, i.e. they could put in nother door

There's a thread here discussing possible uses for a second door.

It will be interesting to see if and how they use it.
