The twenties ironically presented in a novel of the exploitation of a mountaineer evangelist by a traveling salesman who sees good ""property"" in him. There are echos of Billy Sunday, Aimee McPherson, Father Coughlin, in the uses to which the manager puts his man, but the mountaineer himself retains his naivete, his sincerity, his conviction. The boom era from a new slant -- the Florida bubble -- the liquor racket -- the Ku Klux Klan -- and the collapse. Set against the manipulated career of Caleb Craig is the self-made career of the wife who left him because she could not compete with Tucker for his interest. There is enough of action to carry the rather obvious pattern of the story -- but one cannot help but feel that the characterizations lack reality, that the humor is a bit thinly drawn.
