This is a fun, quick read. I really like India's "voice". She's matter-of-fact, brusque, but with an underlying humour that keeps her from sounding too snobby or obnoxious. She makes no apologies for who she is or her chosen profession, which is great, and her profession isn't inserted just for the sake of throwing in sex scenes everwhere. If anything, Carr rather goes out of her way to avoid explicit scenes, which is fine. Something that might bother some people is the language India uses, in particular, "whore" is used often and repeatedly. It fits with the time period and her character, I'm only mentioning it as something that people have a tendancy to be sensitive to. It was a bit surprising at first to see how unsentimental India is in regards to the women who work in her house, but as the narratvie goes on, I realized it's simply that India is completely practical and unsentimental in general. 
 The only nitpick I have is with the backcover blurb rather than the book itself. The blurb likes to put emphasis on the relationship between India and French, which is practically nonexistent in the book. They gain a professional appreciation for each other over time, but aside from one or two very subtle and very brief sentences, there's no romance there at all. Not a complaint about this book in particular, it just annoys me when blurbs try to push the romance angle when it's a very insignificant part of the book. 
 All in all, it was a fun read, nothing terribly deep or fascinating, but a good way to spend some time, and I'll probably pick up at least one more in this series to see where it goes.
