Loving this thread - glad I've finally caught up so that I can join in the discussions too!
I agree that Vincent still being shown must be key in some way - presumably as a pp said re his unravelling will mean he goes back & drops all involved in it.
Hadn't paid attention to the medal originally, so can't remember who owned it / said what etc.
I think Mark is horrible but I don't think he switched the evidence nor do I think Tony is involved - the comment about the family was Marks way of getting under Tonys skin. Otherwise why would he keep searching all these years.
I do think the hoteliers are a good shout now as they were there completely randomly, so those are the only ones really in a position to tell anyone there was an outsider child in town (& would also know about the swimming as they went back to the hotel to get their stuff)
Looking forward to loose ends being tied up next week.
