For that rare metal-invaluable in keeping Earth's technology running-was the target of many greedy eyes. But nevertheless he hadn't figured on the special twist the clever Martian brigands would use. So when he found both the ship and himself suddenly in their hands, he knew that there was only one way in which he could hope to save that cargo and his own secret-that would be by turning space-pirate himself and paying the BRIGANDS OF THE MOON back in their own interplanetary coin. Here is a science-fiction classic, as exciting and ingenious as only a master of super-science could write.
