Neverwhere

I want to meet the girl named Door on the street one night. I will decide to help her and it also means that I suddenly cease to exist for regular people and become real only to the denizens of 'Prague Below', whose inhabitants are generally invisible and non-existent to the people of 'Prague Above'. I will loose my house, my job and nearly my mind as I will travel Prague Below.

And Mr. Rat is ruler !!!
