One of the famous Ace Doubles, with the wonderful original cover, The Mars Monopoly still stands today as a great, fun story in the classic style.

A guy's gotta earn a living someplace—and if it isn't on Earth, it might as well be on Mars. That is if the Syndicate would let you live on the red planet. Bert Schaun found himself washed-up as a round-the-world rocket racer, blacklisted by Thornton McAllister. He tried to make a new life for himself prospecting for uranium in the lonesome vastness of the asteroids.

But McAllister's fury hunted him even to Mars; the issue became a struggle to stay alive against the dangers imposed by McAllister's interplanetary power. And then Bert met Emma, and found that he was not only fighting for his own survival and his sweetheart's, but for the survival, too, of a whole race of Martian outcasts.

Singlehandedly, he had to combat genocide on Mars!
