Plank

I need some help with Blacksteeple Castle day 2(might be due to the fact that I skipped the text...). After getting out of the jail cell I think I saw something tell me to go to the library and read a purple book. I read the book that was open in the middle of the room then I went back outside to the west side (Flower garden side) I don't see anyone and I'm not sure what to do next.

I need help getting through the 6th gyms puzzle I have the first part done but I cant figure out how what to do after I press the switch at the bottom.

Plot spoilers! (I think) I'm stuck in the second prison you get sent to in the game. Right after Ren(I think that's his name) betrays you for Madame X and I have been walking around for a long time and can't find the exit.... probably the first person to get lost here so don't get to mad at me :3 Edit: found out how to get out by myself the door/way-out was hidden in plain sight...
