The
end of the story is told by all three of the boys. I believe that the author
has done this to show a sense of achievement from the boys, they have finally
solved this crime that has been hidden for years. This also adds excitement,
having the last part of the book being read by three characters rather than
just the usual one, it gives a different feeling as you read. Doing this at the
end of the book helps the story feel more finished and not left hanging off. I
feel this is because the story has been told by different people in different
situations, at the end they all come together at the end, having completed
their journey to finish off their tale.
