This is the current story at Beat to a Pulp. I'm not sure if it is truly a crime story (though there is a crime in it) but it is a nice piece of dark psychology. In it, Mary an elderly lady who may not have every one of her marbles readily at hand, likes to feed pigeons*. She has a nemesis who demands that she stop the practice. He scares her and with good reason. He's very mean. And he's willing to break the law to make sure he gets his way.
What makes the story is how Mary reacts to the man she knows as "The Evil Wizard." Can't say anything about that since I'd like you to go take a look at the story for yourself.
There is a fairytale element to the story (king, wizard, princess) that I could wish had been more fully developed. But that would have taken more pages and one of the downfalls of online publishing, I think, is that it's hard to get readers to read longer work on the screen. Ah well. Still a very worthy story.
