Query: Heinlien at his most demented

Although this is not a masterwork by the master of Sci-Phi, it is a very thought provoking book. Take a dirty old man who wants to die, put him in the body of his favorite sectretary (11 on a scale of 1-10), and mix. One of Heinlien's first anti-bible belt novels, it challenges the morals of American society. Although the ending was weak, the charachters are well thought out. Not recomended for children.
