Book three in the series finds Nate and Wolf pursuing a gang of outlaws who helped themselves to $20,000 from the bank in Florence, Arizona Territory, and then disappeared. Although the bounty hunters have plenty of experience at tracking down outlaws, the gang's cunning leader manages to stay one step ahead of them. The chase leads them from Florence to Tucson, then to Goose Flats. Each time Nate and Wolf get close, the outlaws disappear like a dust devil. Although they're facing one of the most challenging adversaries they've encountered so far, neither of the bounty hunters will even consider giving up. Adventure abounds as the reader rides into the old West.
