This is an Q&A / FAQ for the Mission "Masks" in the game "Thief II: The Metal Age" by Looking Glass Studios at


Q: I cannot find the correspondence from Gervasious to the mechanists. Where is it?
Q: What's the deal with the ghosts in the library? Is there some way to put them to rest?

  • in lower level of the library, read the four books
  • open the secret door to the corpses by "frobbing" a certain book left of the secret door
  • apparition will vanish, correspondence karras - gervasius and another letter appears
  • read the correspondence and the letters

Q: OK, I did all that, but still cannot find the correspondence - what is its location?
A: Check the very SE of the higher level of the library.

Q: How do I turn off the traps/gas...?
A: Don't turn it on. The trapped carpets trigger the release of the gas, so better don't step on 'em - use rope/vine arrows shot in the ceiling to get over that floor section tarzan-style.
OK, if you want to "stay on the carpet", you need to turn off the alarm systems. Use the three switches below the three coloured lights (red, green, violet) at the foyer in the 3rd floor. Each switch turns off one of the alarm systems. The colours denote which one - green for the green room etc. Don't turn off more than one! Before you deactivate the second, re-activate the first and so on. [needs confimation, Lytha prefers vine arrows :)]

Q: On the NE of the third floor is a locked door which I can't open with any of my keys or the lockpicks. How can I open it?
A: You can bash it open, using heavy objects, your blackjack or preferably your sword. Behind the door is only a pretty useless elevator which will lead you to another not pickable door in the 2nd floor and right into the arms of two heavily pissed off Guards.
