Margaret Atwood hands over her manuscript for Scribbler Moon that no one will read for 100 years. "I picture this encounter - between my text and the so-far nonexistent reader - as being a little like the red-painted handprint I once saw on the wall of a Mexican cave that had been sealed for over three centuries. Who now can decipher its exact meaning? But its general meaning was universal: any human being could read it. It said: 'Greetings. I was here.'"
