If you know anything about Martian literature, you will of course recognize Tweel, one of the heroes of A Martian Odyssey, by Stanley Weinborn. Written in the 1930's, this tale remains a classic of the genre, and an inspiration for all subsequent writing in science fiction. Listeners will notice the attention the author pays to the details of his imagined world. Geographic descriptions, maps, geological explanations, and a complex psychology allow listeners to travel to a fully formed world in outer space. Jim Robert's cheerful, baritone-voiced narration adds a wonderful new dimension to the experience of this short story.

Campbell's request for "a creature that thinks as well as a man, or better than a man, but not like a man.
