An early short story by Orson Scott Card, Eumenides is about a selfish, manipulative man who finds a baby drowning in a toilet. It’s short and devastating, and I’d prefer not to spoil it, except to say that the ending of this story is what I think of when I think of what atonement and forgiveness really mean.
