One factual correction. Bing Crosby was never divorced but was a widower when he married his second wife.
More generally a book about the Riviera which ignores the setting up of OGC Nice and AFC Monaco football clubs and their achievements leaves a gap in the the understanding of the story.
Football stars are now as famous or even more famous than film stars and even 30 or 40 years ago played a key role in society.
Apart from that an enjoyable read.
