What is the author's style in Smokescreen by Dick Francis?

The language of the novel is English. The novel is written about an English man in the late sixties, early seventies, therefore some of the phrases in the novel might be unfamiliar to the modern reader. The narrator, Link, often uses phrases that will be familiar to those who hail from Europe, but unfamiliar to some Americans. These phrases are slang words, often meant to express displeasure or excitement. There are also foreign phrases in the novel, most from the Bantu or Afrikaans languages. These words are spoken by people Link comes into contact with in South Africa and are often explained either by how they are used or within the dialogue in which they appear.
