This is a look back at an old classic story. Many of the points I make have been made elsewhere, but I think I make a few significant points that I haven't seen anywhere else. And as long as readers keep reading this story and discussing it, I think it's worth consolidating analysis of the mystery where interested readers can check their solution versus someone else's.

Does anyone disagree with my conclusion?
