Spike and Drusilla save Xander

[shadowfire2130.livejournal.com]

Hi,

I'm looking for a fic that I'm pretty sure I read through spnaderfiles but I'm not sure. Anyway, what I remember from this story is that Xander had been kidnapped by another vampire, called herself something like Lady of the Dark, or something like that. Spike and Drusilla came and rescued Xander. Buffy and the other arrive and there's an arguement and Xander has to explain why the two vampires had come to rescue him.

Thanks to anyone who knows what this is.
