I'm stuck in the library. I climbed the ladder, got the letter then moved the ladder over to the gimmick tha flashes and closes. I went to the table and move the gimmick to use the ring on the map at the position 40 and 25. Then I went to the desk and all I get is for that shutter to open and close. I do not get the drawer to open to pick up the supposed articles, that I should get there.

What am I doing wrong? I checked every shelves and sections I could, I tried using the special lamp found in the chest in the red room, nothing works.

Dirko change my red sphere into a crystal ball and I got the secret door to open, but I'm missing the items from the library to move forward.

Can anyone help me?

Thanks

Problem solved
