Query: Splendid parable

The one flaw I find in this engrossing book is that Vance seems to have decided, at that stage of his career, that it needed a little more structural emphasis than his previous books had displayed. This led him to the calamitous device of an opening, "framing," chapter. If this opening chapter should be torn bodily from the book -- and would we might see Vance's own explicit authorization for such a deed! -- it would then be perfect, in all respects.
