Sam Parkhill is obviously a character you love to hate, but I was left baffled when the Martians gave him land deeds to half of Mars, especially after he shot one of them. Why would they do that? Were the deeds real? Why did they chase down Sam so vigorously to talk to him specifically?
I assume not, but did Sam return to Earth in the end?
The 150 Martians that give Same the deeds... it seems like they are still alive at the end of the book with no mention. Perhaps at the end of the book there are still quite a few humans and martians left on the planet? If so, was anything else written to talk about all of the people still on Mars, and maybe they all found a way to live in peace in the end?
