Hello all   I'm playing "My Father Lied". I'm currently stuck in a green room, which contains a desk, two filing cabinets, and four idols, one of them is tipped on its side. There is what seems to be a light-matching puzzle on one of the walls. I've checked every hotspot, but could not find any clue to the puzzle. The door is locked from the outside, which, according to a note on the table, is a logical possibility. I Have this nagging feeling that I've missed some essential info, or overlooked an important inventory item which could have helped me out. 

Any suggestions?

Hi! Have you tried to check the desk sides? There are two clues Uber the drawer. Let me know if you need the full solution. You got this.
