Someone is killing witches in Chicagoland, leaving biblical verses as tags on or near the bodies, cheerful messages like "Suffer not a witch to live!"
Harry quickly learns that someone wearing a grey cloak--the mark of a White Council Warden--has been seen with some of the victims. Harry's a Warden, he's in Chicago, and people are afraid he's the killer. He's got a less-than-shiny reputation.
And what the hell is up with Thomas, Harry's vampire half-brother? Why do some of the clues point to him as the killer?
Cowl--one of the Necromancers from "Dead Beat"--is back in town. Where does he fit in?
That's not all!
Harry's ex is in town.
