I understand that James Bond was loosely patterned after ( the author) Ian Flemming's escapades in WW-2.
Evidently Casino Royale actually happened but Flemming lost His Shirt instead of winning.
I wish I could remember the name of the Book as it was a pretty good read.
You just GAVE the name of the book: Casino Royale, the first Bond book, about 1953. The movie retained that name.
All of the Bond books were good reads, as long as Fleming was writing them. I haven't really liked any by the later authors.
I think Peter O'Donnell was wise to kill off Modesty Blaise when he retired. No one but him could have written her right, and the movies stank. A TV show even tried to make Modesty and Willie Garvin into Americans, in CA. Sheesh... But the novels and the comic strip were excellent. Bound volumes of the comics are available. Only one US newspaper ran the comic, and even it had to do some censorship, as prudish American family values were an issue. The comics ran in 57 countries. If you liked the book Bond, Search for Modesty Blaise. I think you'd like her.
Donald Hamilton's Matt Helm books were good, too, but ruined as movies. Dean Martin was not a good choice as Helm, and he made a spoof of the books.
It is irrelevant that Roger Moore made a good comic Bond. James Bond was not written to be a comic character!
BTW, I read Moore's autobiography and thought less of him after I did.
Be aware that Casino Royale was also made into a spoof movie starring David Niven. Groan...
