‘‘I feel like the last man in the world because I think that all those three hundred sleepers behind me are dead. They sleep so well I think that every scruffy head's kicked the bucket in the night and I'm the only one left, and when I look out into the bushes and frozen ponds I have the feeling that it's going to get colder and colder until everything I can see, meaning my red arms as well, is going to be covered with a thousand miles of ice, all the earth, right up to the sky and over every bit of land and sea.’’
