He was initially unsure whether the work was suitable for publication, but was assured by his friend, the novelist William Plomer, that the novel had promise. Fleming wrote the draft in early 1952 at his Goldeneye estate in Jamaica while awaiting his marriage. Fleming used his wartime experiences as a member of the Naval Intelligence Division, and the people he met during his work, to provide plot elements the character of Bond also reflected many of Fleming's personal tastes. Bond is supported in his endeavours by Vesper Lynd, a member of his own service, as well as Felix Leiter of the CIA and René Mathis of the French Deuxième Bureau. The story concerns the British secret agent James Bond, gambling at the casino in Royale-les-Eaux to try and bankrupt Le Chiffre, the treasurer of a French union and a member of the Russian secret service. Published in 1953, it is the first James Bond book, and it paved the way for a further eleven novels and two short story collections by Fleming, followed by numerous continuation Bond novels by other authors. Casino Royale is the first novel by the British author Ian Fleming.
