Features that sort of bad historical novel writing where people don't talk normally, they announce information like "Don't you know it's 1925 and the Charleston is the rage?" Also it's clear a Brit didn't write this, the slang is wrong and seeing how many times you can mention those goofy Mitford family nicknames like Muv and Farve and Debbo and Prod gets old. With subjects like this the book should have been a lot better.
