In that case, many thanks, not-so-mysterious kind person!
Just whittled my shortlist down, with some difficulty:
Siren by Talysia
The Undeath of Johnny Cross, P.I. by digs
Waiting For Contact by mosaix
Touch by Mouse
In the end, I had to go for Talysia, by the barest margin over the others. The very barest margin. Such great entries this month, all around.
I'm your other fan, Culhwch. I like the way the punchline came right down to the last two words before it all made sense.
My overall runner-up was Mouse's very visceral entry, which stuck with me despite attempts to forget it.
There are stories good enough to win that don't have any votes yet.
Felt like I'd failed massively this month, so you've both made me stupidly happy with those mentions.
