What are the motifs in Octopussy by Ian Fleming?

Secret worlds are a motif in this story. Throughout the Bond stories the exposition of various facets of the world of the so-called Secret Service are revealed in a sporadic and haphazard way. If the reader tries consciously to build a picture of the Double O section and the organization of which it is a part, the picture can scarcely even qualify as a sketch. For a start, there is no mention of any other members of Bond's section.
