In reply to Ridge:
> I thought the implication was he'd found his son, (drawing in the frost on the window of the flat, possibly look of recognition from the kid looking at the picture), but was labelled a nutter?
I got a very different meaning from the ending and I thought it was also good ending and appropriate for a story like this.
He hadn't found his son at all, he had gone slowly mad which was the whole point. It is virtually impossible to get over something like this. The Russian police said that he had been doing this same thing for ages. Any son would do for him, he just couldn't accept that he was really gone. He wasn't labelled a nutter, he really was a nutter.
