Operational Necessity

It's a story about spies, in a fandom so small you've probably never heard of it. Alas. I swear the source is worth your while — it's clever and intense and morally ambiguous and available on DVD, and this story was written assuming no or minimal familiarity with source, so don't worry -- you can follow it even if you haven't seen the show. Minimal spoilers for the second season. Written because I wanted more Karen (and, okay, I was in bed with a head cold and my wireless kept cutting out). There's some sex, though it's not particularly explicit; there's some violence; and everyone involved lies for a living.
