There are such a lot of things that have no place in summer and autumn and spring. Everything that's a little shy and a little rum. Some kinds of night animals and people that don't fit in with others and that nobody really believes in. They keep out of the way all the year. And then when everything's quiet and white and the nights are long and most people are asleep—then they appear.
