The Scapegoat by Daphne Du Maurier
I wrote a song a couple of years ago about going to bed one night and then waking up the next morning as a different person. And, having just finished "The Scapegoat" by Daphne Du Maurier, it seems to me that the song could have been based on this story, if I hadn't written it years before I'd even heard of the book. It's a great book - the unsettling beginning, where a man meets his exact double that then goes on to force them to exchange lives. is pretty dark. That the other man's family don't seem to notice any difference in the man seems a little far-fetched at first, but then you realise that you would just accept someone you know and love to be that person if they looked exactly the same, even if they acted a little strangely. The man ends up not knowing who he is at all, which of the two men is the real one and which is the fake; I read it as an extreme example of something I'm sure a lot of people go through in life, pretending to be different people on a daily basis, eventually forgetting who they really are.
