Paul is a detective in his forties. Dorothy is 15 and going through a serious identity crisis. She's up- per-middle class whilst he's an outsider to Brussel's small well-to-do society. The only thing that links them is Paul's knowledge that he is Dorothy's biological father. Over the years, away from Dorothy, Paul has always lived with this secret. Now back in Brussels he has been watching her from afar, without ever daring to approach her. They probably never would have spoken if Dorothy hadn't decided, one day, to come knocking at his door. She's heard he's a detective and she wants him to help her find her biological father..
