Spike wakes up feral and Buffy has to take care of him.
Written for the prompt "mystery" for Buffyverse bingo and at least partially inspired by Off the Leash by Soulburnt.
Story Notes:This is sort of a conceptual piece, by which I mean the mystery ain't gettin' solved. You can come up with your own idea of who the villain was and what happened. The time period is also nebulous, so place it wherever you'd like in the timeline.
