Police Your Planet

Police Your Planet was written by Lester del Rey under the pseudonym of Erik van Lhin. Lester del Rey's name is mentioned on some book covers.

Bruce Gordon was an ex-fighter, ex-gambler, ex-cop, ex-reporter and now he was an ex-patriot of Earth. Security shipped him to Mars with a knife, 100 credits, and a yellow card that meant no return. He was also, he told himself, an ex-do-gooder. From then on he would take care of Number One! But in Marsport, nothing was that simple. Here the vices of Earth seemed tame and insipid. When he bought a commission in the Marsport police force, he found that graft was not only a fine art, but the official Martian way of life. So he joined the system. And then he met Sheila, who was out for blood – his!
