What is the author's style in On Her Majesty's Secret Service by Ian Fleming?

Fleming uses a highly articulate vocabulary throughout the novel. In the resignation letter that Bond composes, the language is even more ornate, showing that Bond aspires to greatness in everything, even his language. Throughout the novel, European words and phrases, predominantly French and German, are interspersed with the English dialogue and descriptions. The international language reminds the reader of the exotic international lifestyle that Bond is living.
