Above a black couch covered in pillows, a picture on the wall shows a world of immense grandiosity, in which everything is relative: the movement of a marble floor, the creaking of a typewriter, the hanging of a label, the falling of an illustration, the open-work of a manuscript.
In such stories, the subject is almost always the same: a man who knows he is going blind comes across a picture which he believes to be true, and wonders whether the person seen is really his father or his twin brother.
