I just got passed the Post Mortem portrait puzzle (with some walkthrough help of course), where Gus had to draw the portrait of a suspect murderer using descriptions of various witnesses.
Even now I believe my portrait makes more sense than the one given in the walkthrough. I also had my brother do the puzzle and he drew exact same portrait as I did, except for the suspect's eyes.
It seems that the puzzle was meant to be solved with some trial and error, which wouldn't be that bad, if Gus didn't have to go through the same conversation (15-20 seconds long) with Malet before every try. So after 4 days of banging my head on the wall, I gave up
