Recently I wrote a Holmes-Star Trek fusion. The version of Holmes canon is deliberately mixed — it draws mostly from ACD but a few things from Sherlock. Back in the day on alt.startrek.creative.erotica.moderated (ASCEM) I was classed with the Vulcanologists, so the story is also a bit heavy on Vulcan worldbuilding, and is set in the “alternate original series” universe where Vulcan was destroyed. I’ve tried to make it accessible to non-Trek folks with worldbuilding & sexuality appendices.

With Careful Hands.
