I am a novelist, and I suppose I have made up this story. I write “I suppose,” though I know for a fact that I have made it up, but yet I keep fancying that it must have happened on Christmas Eve in some great town in a time of terrible frost. I have a vision of a boy, a little boy, six years old or even younger. This boy woke up that morning in a cold damp cellar. He was dressed in a sort of little dressing-gown and was shivering with cold.
