"Love Letters on the Nightmare Sea" by Rachael K. Jones (first published in Flash Fiction Online)
I'm having trouble finding the time to hunt down whether individual stories are originals or not, presumably Podcastle staff has that information on hand, would you mind checking those 4 stories, where the episode post didn't specify yay or nay?
