where are they? i have found the head and torso one near maevars guild and the other in the tomb of the seeing eye, also in the sewers i have found a hidden door in the top r/h corner but it is locked and yoshimo can't pick it perhaps that is the 3rd location and how do i get in?

Third one is in the docks district opposite the temple of helm, to the south. The door faces westwards.

Sorry I meant to say BRIDGE district.
