If you are going to do a piece on "life in a brothel"--it might be a good idea to go to an actual brothel. Instead, this piece is an extended phoner with an author who had spent time in a brothel and wrote a book about it. This places the listener three layers removed from people who work/live/patronize brothels. It's too "hands off" to ring as real and authentic. This extreme disconnection zaps the substance from the subject. This might make for an interesting three-minute piece on the book and its subject, but it doesn't work in this extended format.
