Before going there he buys a Martian woman to be his sex slave. During the story he treats her badly and thinks of her as a lesser being who is too dumb to act in her defense. In the end the slave locks him out of the station, and when he tries to drill his way back in the Martian slave builds a bomb that would explode in case of depressurization and shows it to him to stop him from trying that. Finally the man dies while the Martian woman sits calmly in the station and reads something.
