In the book with the porn set, two of the set guys started funschway investigations following the events of the book and direct exposure to the supernatural.

with the recent events in Chicago and Outlaw, its possible that these two guys could be poking around and helping out as they are already initiated into the supernatural and detective work. perhaps they could even team up with Harry at some point at least briefly if a case they are working intersects whatever Harry is up to.

So near the end of Outlaw, Dresden talks to his apprentice about magical drugs. The thought ocured to me that if 3rd eye existed, it stands to reason that there are other magical steroids out there operating in towns beyond Chicago that Dresden hasn't shut down yet. This stands to reason that the Black Council is running this magical steroid ring, and by consequence that The man running it may be the magical equivalent to Bane.
