Proven Guilty opens with Harry Dresden, now a Warden for the White Council, attending the execution of a teenage wizard who has killed and maimed using dark wizardry. It doesn't take much for Harry to realize this is not just exacting justice for the wrong that was done but a warning to himself that the council doesn't trust him and is still watching. Ebenezar, Harry's mentor, asks him to check with his faerie contacts to see if he can learn why they haven't entered into the war against the Red Court vampires. Then a message from the Gatekeeper warns Harry that dark magic is being used in Chicago and for Harry to check it out. On the way home, Harry is nearly killed in a car accident. Finally, home at last, Harry gets a phone call from Molly Carpenter asking him to come bail her out of jail and not to tell her parents. After posting bail for Molly's boyfriend, he takes her to her parents and ends up promising Michael, who's leaving on a mission, to watch over the family and help to mend the break between Molly and her mother. Next thing he knows he's attending the SplatterCon!!! horror convention as Molly's guest and the death toll is rising. Harry is again involved in saving Chicago from the supernatural baddies but he's trying even harder to save his friends and the family he respects and loves.
