If he’s a military officer in time of war, he might just decide to switch sides...

Brigands of the Moon by Ray Cummings Brigands of the Moon

Gregg Haljan was aware that there was a certain danger in having the giant spaceship Planetara stop off at the moon to pick up Grantline’s special cargo of moon ore. 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. (From the Gutenberg e-text)

But even so none suspected then just how much trouble this new world would make...

To this end I have conceived myself a writer of that future time, addressing his contemporary public. You are to imagine...
