“Hangman’s Break” by Albert Tucher, in Ellery Queen's Mystery Magazine, July 2013.
I have written before about the type of story I call the Unknown Narrator. That means that all the reader knows about the narrator is what other people say about him/her -- and those people are wrong. Tucher's story is a variation - the people really do know about the narrator's secrets, but the reader has to slowly figure them out.
The year is 1969 and hero is a police chief who got his job in part because during World War II he fought alongside the son of the local industrialist. Now that same son is found hanged on a railroad bridge. Suicide, or something else? We learn the grim details of his war experience, and then we learn how the after-war yearas have effected our hero. And some rough semblance of justice is meted out.
