Thx,
It's the last image on tab 6, before it is the Lauren handjob scene and after it comes the cooking scene.
I only have 39 scenes but the image is labeled 41, but is 36th in the gallery.
Yeah, I got it! When you return to captain cabin after Tovenaar (beginning of chapter 2) after talking to the elf woman, Anna comes in. You have to turn her down and just take the map. Then, when Tovenaar excites and Lauren comes in, you have to turn her down too. Then you will hear a knock on the wood and someone will be in the hole in the wall.
