Hello folks, former poster that hasn't been back here for a long time.  Wanted to throw some personal theories in here and get some feedback, see what the community as a whole thinks of them.

First theory: Denarian coins are NOT returned to circulation via divine will, but rather a lack of understanding of Nicodemus and the powers Anduriel grants him.

So we are told by Michael I believe that he thinks the coins are MEANT to be in circulation, that is why they always get recaptured by the Denarians; we also know however that very few people realize Nicodemus can hear anything said within hearing distance of a shadow AND he makes sure to destroy the church's records of him every so often.  Thus, I believe the divine will theory is just what the church has come to theorize because they are regularly trusting people beyond repute with hiding/safeguarding the coins. Nicodemus uses Anduriel to find the coins and liberate them, the church has no idea how because only truly devout/pious type are entrusted with them and thus decide it must be divine will.  The truth is they are just ignorant to the extent of which Nicodemus can infiltrate their top secret hidey holes through Anduriel.

Second theory: Kim Delaney is Kumori

As far as I know, the only thing we know about Kumori's character outside of her appearances is a WoJ that her identity will be really rough on Harry when it is revealed.  I like Kim for Kumori for a few reasons: 1. she is described as tall as Kumori and Kim is described as "statuesque." 2. There is a really striking similarity/symmetry in how Dresden tries to warn Kim Delaney off the Macfinn case in Fool Moon and how Kumori tries to warn Dresden off the case against Cowl in Dead Beat. The two conversations mirror each other ridiculously closely, both instances of 1 person withholding information that would be incredibly important to the other but withholding that information because they think they're doing the right thing. 3.  Kumori chose to save a random life for no reason other than it was the right thing to do, while also putting herself and her mission in jeopardy.  Reminiscent of how Kumori tried to help Macfinn, no? Basic theory is Cowl is running around behind the scenes pulling strings in Chicago, loses an apprentice to Dresden (Sells) and then has Dresden meddling in another plan of his(hexenwolf belts).  While surveilling the situation in Chicago he recognizes Delaney has untapped potential as well as insider info on the recurring Dresden problem and Chicago in general, he resurrects her to be his new apprentice and help him figure out how best to deal with Dresden.

Theory 3: the books follow a pattern.

The book patterns I have noticed and think might be getting fleshed out are:
Every 3rd Book is a Vampire focused book.
Every 4th book is a Fae focused book.
Every 5th book is a Denarian focused book.
Every 7th book is Black Council and will have a lead up to and climax on Halloween.
Every prime numbered book starting at 7 is a Black Council book.

What do you guys think?
