How can i lay my Hand's on the Rapax treasure's?? I suspect that there's a lot of them there.....

You cannot enter the room with the chests, the treasure consists of the 3 letter which you can use to get three items, one is zatoichi bo. It is better than nothing but not enough for so many chests.

yes there are the 3 letters from the constable safe for Items. Also one letter in queens room for the key to her treasure area. has anyone found any other letters usable for items in the treasury?

Where can i find the key to the constables safe??

in the basement, there are a couple of friendly drunken rapax.. in a room not far away from them, is the constable, kill him without making too much noice, he'll drop the key, and the others won't know there's a corpse in the adjoining room.

You don't have to kill the constable. Give him some ale and try pick pocket. You don't have to be good at pick pocket, at least when I tried it.
