thanks. the door is after you go down the trapdoor in the floor and down the stairs, down a long hallway... i think it's on the same level as the computer.
it's the first door i've come to that doesn't show the handle icon, so i guess there's something more complicated to it than just opening it. i'll figure it out!
interesting game so far, especially in comparison to Syberia (which i just finished). i prefer 3rd person to 1st, but so far the storyline is making up for that.
