Then [Kim Delaney] lied to him as to why she wanted the knowledge, she wanted to get the payment and credit from MacFinn, so she tried to pull it off herself, in way over her head,and she died for it.
This topic is listed under DF Spoilers so I don't think using the Spoiler function is strictly needed but out of an abundance of caution . . .
Maybe she got better. I will be surprised if Kim Delaney isn't Kumori. We know her master Cowl is a necromancer, as is Kumori. Kumori's and Kim's physical descriptions match, and Kumori speaks to Dresden in a familiar way, as if she knows him, and also in a caring, almost affection way at times.
Thank you all, I appreciate your thoughts on it. I had forgotten about Kim until you mentioned her. I've been reading the books so far apart due to lack of time that I forget some of the previous stuff. I just got past the part yesterday where he went to Sheila's apartment with the wards up and she used her ability, so I realize now she already knew and didn't need his help anyway, so I had apparently forgotten a part of their initial meeting too, but my curiosity about unknowns would still have remained even if I had remembered that.
Except, and I will put it under spoiler if you haven't read that part yet, there is a bit of a problem with Sheila;
Sheila is an illusion, all in Harry's head! She was created by Lasciel's shadow, the apartment isn't real, none of it. It wasn't until Butters pointed out that none of what Harry thought he was seeing and experiencing was real, Harry didn't know. This is how Harry discovered that Lasciel's shadow who later becomes Lash was in his head./spoiler]
I get the part about memory, with so many books sometimes it all runs together and easy to get mixed up. Many of us have read and reread many of the books in the series more than once so stuff sticks out in our memories. I do suggest that you go back and reread the whole thing about Sheila.
