All five Nat Holcomb stories (so far) can be found at http://shifti.org/wiki/User:Trismegistus_Shandy. I may or may not get around to posting the third through fifth stories here on Stardust. There's a sixth story I'm not finished with yet; it might be the last but I'm not sure. When and if I finish it, I'll probably serialize an early draft on the tg_fiction mailing list, as I did with the first five, and later post a final draft to Shifti (and maybe here).
