Stirring the Ashes

The story is set well into season three and is a followup of sorts to my last fic, Embers. You don't need to have read Embers, but it would help a tiny bit if you had. Joan and Sherlock are back to working as partners. This one kind of got out of hand. It's very fluffy joanlock and be warned by chapter 3 it's solid joanlock. Slight spoilers with use of name of 2 new characters.
