The Bond character is a Secret Service agent, code number 007, residing in London but active internationally. Bond was a composite character who was based on a number of commandos whom Fleming knew during his service in the Naval Intelligence Division during World War II, to whom Fleming added his own style and a number of his own tastes; Bond's name was appropriated from American ornithologist James Bond. Bond has a number of character traits which run throughout the books, including an enjoyment of cars, a love of food and drink, and an average intake of sixty custom-made cigarettes a day.
