A review by vintonole
The Master Mind of Mars by Edgar Rice Burroughs

1.0

Another American finds himself on Mars in the laboratories of a Martian medical savant who gains wealth by switching out the brains of local aristocrats and jeddaks with those of beautiful slaves or criminals. Somehow this works and produces a series of wrongs that must be righted. The American Ulysses Paxton sets off with a cadre to the nearby city of Pfundahl to rescue the body of one of these hapless victims. That it is now hosting the city states leader is just a minor problem. John Carter makes a quick cameo appearance at the end of the story in case you were wondering.

Definitely not the best in the series so far, but it does make 'The Chessmen of Mars' look much better. I think I read this more to experience the ancient paperback with the beautiful cover art and old-book smell.
