Suggest me a book (or series) that’s a mixture of Supernatural and Criminal Minds.

I'm really interested in reading a more "agency" version of Supernatural, where the main characters work with or as some sort of agency to hunt down or police non-humans.

I've already heard of the Dresden Files, the Cal Leandros Series, the books based off the SPN show, the Vampire Diaries, Buffy, Vampire Academy, Kelley Armstrong's books (loved these), Twilight, Percy Jackson (but I'm going more supernatural than godly), the Bitten Series, and the Mortal Instruments series.

P.S. Would also love it if there's spice.
