In a travesty of justice, bounty hunter Brodie Latimer's sister Lucinda is found guilty of murder. Thwarted, when a witness is killed, but convinced of her innocence, he vows to find the real killer and, as more of Hamilton's leading figures die in mysterious circumstances, the clues lead him to Derrick Shelby, a man known as the Devil's marshal.

The only trouble is, Derrick died a year ago. How can Brodie clear his sister's name and bring the guilty to justice when the killer appears to be the specter of a long dead lawman?
