Strangely enough, I read pretty much the only X-Files fic I ever read from Xanthe -- 24/7. It's actually a BDSM slave fic, with Skinner as Mulder's Dom. REALLY not my thing, not even the pairing. But it came highly recommended, I started reading anyway and somehow got hooked, she's just that good a writer. :-)

I'm tempted to check out her Sherlock stories, but the very first summary I looked at said Holmescest, and ... uh, no.

Waiting for your message, then. :-) Loui's best-known work is "Teacher's Pet", I think.
