In The Watchmaker, the first room you enter in the old wing is a white room with some chairs and has the painting behind the dresser. It also has a light switch on the wall, next to the door which you can flip, but I cannot figure out what it does. It does not turn the lights in or outside the room on or off, so I figure that it must have some other, more significant effect, but all the walkthroughs I could find do not even mention it.
Does anybody know what, or if nothing, why it's there?
