Blood For a Dirty Dollar is the last book in the series of five novels chronicling the adventures of the man with no name. It is the fourth to be written by Joe Millard.
Two scientists known for developing fuel for auto vehicles, are missing after heading to Veldon Castle near the Broken Hills. And the bandit chief Bandera, whose hideout is in the Broken Hills, has something to do with it. While investigating, the Man with No Name runs into Saginaw Kirp, life insurance man and Lee Van Cleef look-a-like, and together they work to find the missing men. But why has a castle been built out in that spot in the desert? What secrets could Lord Veldon be hiding?
