What is the author's style in Our Man in Havana by Graham Greene?

The novel is written in the third person. The narrator is reliable and knows all the inner thoughts and feelings of the characters. The novel is also largely dialogue-driven, the spoken word being very important to the story. The narrator also describes the scenery and gives opinions on it.

The language of the novel is often satirical and circular. Many of the characters are portrayed as comical but still play it straight. The dialogue of many of the characters is spoken in a serious manner but is obviously meant to be humorous.

The book has a somewhat unusual structure, it is split into five parts, each with several chapters. Some of the chapters themselves are also split into shorter numbered sections. The chapters are all quite short and can be read quickly. The sections of the parts of the book all end with an interlude in London.
