Okay, I thought I could do this on my own, but I can't find the blamed thing(s).
I'm looking for a story (or stories; it may be more than one) where Lois and Clark are working to bring down Lex. (I think she knows the secret. She might not.) Anyway, in the course of the story, her apartment is damaged - I believe permanently. Lex steps in with an offer of a place. Oh! Yes, now I remember, Lois does know CK = S, because she engineers it so that Clark comes along to look at the place, and it's riddled with listening devices.
Thanks!
(I'll be
if this turns out to be one of Nan's. I've just finished rereading quite a lot of her work.)
