Jose Saramago, author or Blindness, The Double and Cain.
Digging on him today I realized I've already watched one of his movies, and always wanted to see the other.
Enemy-which was a hell of a ride. Blindness is the other, I remember the preview and it was alarming and attractive.
The world is one beautiful ironic situation ain't it? I'm going to order the book Cain this week.
