There's a story to illustrate this, but then -- and this is the kicker -- we never find out who the guy is or what his beef was. If we had, it would have been an acceptable story. But as it is, I can't see what people will get of value from spending their time reading it (Aside from the commercial value the writers got, of course, and I don't begrudge them that. Just trying to help them with providing a better trade for the reader next time)
This article promised to be a great detective story, with lots of twists and perhaps with a surprise ending. But it wasn't that. That makes it frustrating.
