Ending of The Murder of Roger Ackroyd
SPOILERS!! I just finished TMORA and loved it, but I simply don’t get the ending. I understand that the doctor is going to commit suicide rather than face prosecution for the blackmailing and the murder. But other than that, I don’t understand what his suicide accomplishes. The mere fact of his suicide will confirm his guilt, and it won’t save Caroline from shame; it will avoid the spectacle of a trial is all. I also didn’t understand the point of his manuscript and was confused by Poirot insisting that in the manuscript Ralph Paton could not be guilty of anything. I thought the manuscript was supposed to be the actual story — which was a very good one — so why would Poirot issue the caution about Ralph Paton?
