The shortest story in Uncertainties III edited by Lynda E. Rucker (Swan River Press) is by R.S. Knight.
'Before I Walked Away' is a poetic, powerful vignette, written in the first person. It's star is Kat, a student in a black negligee and fishnets, and brandishing a whip. The narrator, Helen, is arguably in love with Kat, but something is wrong with this relationship. They are close, but between them falls a shadow. A silly argument has apparently led to tragic consequences. But for whom?
This story packs a lot into a few pages. As a ghost story, I think it works. As a story that might not involve a ghost, it's just as effective. As a portrait of youth, love, and loss, it is painfully good.
