Query: Rip Roaring Times

I read this book with great pleasure. The research that makes it so enjoyable is evident. This is not a quick pot boiler; but rather a scholarly, highly amusing and enlightening trip to the not so distant American past. I found a fine companion piece to follow, the biography of Mrs. Warren G. Harding, the Duchess. I'm ever so pleased to have set the scene with Chin Music. I eagerly await Levitt's next novel.
