History of Spike's fight training

Hi again,
There's another fiction that's taunted me. The fiction goes through the history of Spike (not sure but think someone is showing Buffy). After he fights the slayer in China, he seeks out training with a fight specialist demon & learns many maneuvers/techniques & martial arts. He wants to fight more slayers. He seeks out the new slayer at a San Francisco hotel in the early 20th century, but it turns out she just got called & doesn't know it yet, so Spike lets her go because it wouldn't be fair. Does anyone remember this story & author?

I keep having the strangest dream. Every night it's the same thing: a dark room, a big bed, and a silent vampire that I can feel, but not see. I'd be wigged, except it's just a dream, right? It'll be a cold day in hell before I ever willingly sleep with a vampire again...

Buffy witnesses Spike fight the Chinese Slayer, train under a Chinese demon, and let a new slayer run away through flashbacks in chapter 55, The West Wind.
