“With Unclean Hands,” by Adam-Troy Castro (Analog Science Fiction and Fact, November 2011). It’s no secret that I’m a huge fan of Castro’s work, and I’ve nominated his stories multiple times.
Being an Analog story, this one is very different in tone and style from his nominated short story, “Her Husband’s Hands.” I can’t say much about it because the story relies on the reader discovering the morality play along with the characters. Do read it.
