Hi Gus, you are right, I am a book worm of sorts.   It´s very kind of you to tell me about the library in the neighbourhood of Botafogo, certainly I will be there sometime.  I wonder if you meant library or bookshop, anyway it could be both.

    When I was in Rio, I would go to Tiradentes square and make the rounds in thousands of second-hand book stores there, I bought plenty of novels, textbooks, book on Calculus, whatever you have.

     You are right about the price of the bargain you had, yep it was for a song, being such a Grisham vintage! by the way I bought and read it too. 

     Thanks for the tip.
