Temple secret help

[Jameslandia]

I have 28 of the 30 Temple secrets. I know that picking up the Stone at the end counts as a secret (I confirmed it) so I only need the one more. I have done some of the Prison level but I'd rather find the last Temple secret and then focus on moving on to the next areas.

I saw the list of secrets in another post (in French) and translated on Google. There were two secrets mentioned in the early Ground Floor area that I don't recognize the reference to.

Secret 1. Canteen: Not sure at all what or where this is referring to. So any help or hints on this one would be appreciated.

Secret 3. Office of Jarius: Does this have something to do with the little peg button beside the desk that can be pushed in and out? Done that several times but haven't noticed any changes. Looked all over the room for another button or something else to push/pull etc. but so far can't fine anything. I don't recall finding any kind of secret in the office (with the big plant area in the middle). I remember a note in one of the other side rooms (the girl's or Jarius) referring to a hiding place but it also sounded like it might not be findable until later in the game. So what am I missing, if anything?

Thanks!

Hello,

Secret 1:
In the canteen, behind the curtain, there is a small room with a lot of boxes etc. In fact, there is also a secret room that you can access from there. A wall can be opened. However, you need to open it from the corridor just before you enter the canteen. Check the curtain near the entry of the canteen, there is a pressure plate on the floor. You can burn the curtain to see the pressure plate from the corridor.

Secret 2:
Yes, you got it. There is a secret area in the Office of Jarius. But you need to push TWO buttons to open it. The second one on a column.

Let me know about your progress. Good luck!
