Thank you tanuno for your questioning and horizon-broadening comment.
I think that at the end of this second part you will see in what a shabby corner of the world the "Brothel behind the border" is to be found.
From the perspective of our modern western world, it is a very backward area in which Paula M. likes to travel as a photographer. It is above all the warm and lovable people who live there in a culture from an earlier time and of course above all the really beautiful women that Paula M. is fascinated by.
And maybe there is also this tunnel that tanuno imagines...
