Badge of Infamy

Daniel Feldman was a doctor once. He made the mistake of saving a friend’s life in violation of Medical Lobby rules. Now, he’s a pariah, shunned by all, forbidden to touch another patient. But things are more loose on Mars. There, Doc Feldman is welcomed by the colonists, even as he’s hunted by the authorities. But, when he discovers a Martian plague may soon wipe out humanity on two planets, Feldman finds himself a pivotal figure. War erupts. Earth is poised to wipe out the Mars colony utterly. A cure to the plague is the price of peace, and only Feldman can find it

Thinly veiled criticism of government and corruption of government. Still a fun read if you're partial to older science fiction.

Really good Classic SF story. There was a few times when I wanted to kick some of the characters in the pants.

It's my favorite Del Rey book so far.

I was all set to write a great review, then I read this one and decided mine would have been completely superfluous. Just read his.
