Review of prisoners:
- right of stairs is the martial art teacher - Chinese - that will teach Jack.
- right of this prisoner is the one that wants a password and talks about Ming vase.
- hallway right of password prisoner will be the lisping prisoner that gives the password.
Now go downstairs to next level. Look around.
Take the petroleum lamp at right end of hallway.
Look at that lamp in inventory to get the lampshade, wick and petroleum.
You can then make a lighter for this.
At bottom of this hallway is the guard.
You have to learn how to fight - try to get to the martial arts teacher then.
He will want a book.
The guard has that book.
Is this where you are now?
I found a video walkthrough here.
Hope that helps.
