Buffy is a 911 operator with Spike - all human

I was reading this one a long time ago and somehow cannot find it again. Spike was a 911 operator but used to be an undercover detective. He and Buffy work together at dispatch. Does this ring any bells with anyone? I know I have the thing (it was not finished when I was reading it, I'm hoping it is now) but I cannot recall either title or author. Thanks for any help.

Is it Invisible by Alvarii?

Summary: Buffy Summers was a happy, carefree girl who wanted to save the world. Elizabeth Summers is a woman surrounded by darkness who can't even see a way to save herself. No matter how she struggles, each day adds to what seems a never-ending list of failures. But William Giles doesn't see it that way at all, so there's a chance that they can save each other.

To be honest, I haven't read the fic, but I was browsing through the short list of AH at the workplace fics, and that turned up. And Spike seems to be a 911 operator, from what I see of the first chap. It's still unfinished...

Read a bit more of it, and I'm almost positive it's the fic you're searching for.

It is "Invisible." This was an awesome story, but sadly left unfinished on SR (even though the author claimed to have nearly finished it). Spike was indeed a cop, who had to go undercover at one point, which caused him to be hurt. I remember Angel was a huge jerk in the fic too. The characterizations are excellent and it is all really well done.

Yes! That's the one. Sadly, it hasn 't progressed past where I last read it. But at least I know where it is now. I love that story.

Holy cow, what an amazing story. Thanks for putting up this request! And thanks to Guest who remembered it, so us who haven't read it, can!
