Police Your Planet

Bruce Gordon is an ex-fighter, ex-gambler, ex-cop, ex-reporter, and now he is an ex-patriot of Earth. Security ships him to Mars with a yellow card that means no return. A SF novel that would appeal to Mickey Spillane fans, Police Your Planet features lots of hands-on violence, assorted beatings, and blood. But this isn't just a crime novel put into space - this is a hard SF novel, and the terraforming of Mars is central to the story.
