How does the author use symbolism in the novel, Mrs. Bathurst?

There are few traditional symbols in the story, since most of "Mrs. Bathurst" consists of dialogue. Moreover, the symbols that might be interpreted in the story seem to be not fully formed. The object in Mr. Hooper's pocket, for instance, which might be the set of false teeth that he has taken from the burnt corpse of Mr. Vickery, never appear. The image of Mrs. Bathurst on the movie screen is another image that is not fully materialized, since a movie image stands in for the real person, and because Mrs. Bathurst is possibly already dead at the time Mr. Vickery and Mr. Pyecroft observe her image at the cinema in Cape Town.
