'A Fistful of Warlocks' is set in Dodge City, Kansas, during the 19th century. Wyatt Earp is a supporting character. This is not a time travel story, so Harry Dresden does not appear. At this point, Ebenezar McCoy is Captain of the Wardens of the White Council. It's not stated whether or not he is already the Blackstaff. (He doesn't appear in the story, he's just mentioned.)

Our protagonist is the woman who will one day be the Wardens' Captain: Anastasia Luccio. She's hunting for a murder, the Warlock Alexander Page. We are told about part of what he did to his three victims. It was bad enough that I'm glad the rest was left out. Her magnificent white horse is really a näcken named Karl. (Karl lost a wager with Anastasia.)

Warden Luccio meets Wyatt Earp at the Long Branch Dance Hall and Saloon, which is a real place. There she finds Page, who is hanging out with other warlocks. Oops.

Remember Grevane from Dead Beat, book seven in the Dresden Files? He's here as Heinrich Kemmler's apprentice. (No, Bob the skull doesn't appear.) Let's just say that he, his fellow sorcerers, and his mentor are making things tough for Luccio. There's a good supernatural fight scene, and the end of which some characters should have gotten out of Dodge while they had the chance.

Horse fans: You probably wouldn't want to ride him in his proper form, but do enjoy Karl in his disguise. ( )
