If you've already read "The Alienist" you can skip the first 100 pages of this book, it takes that long for Carr to settle into telling the story of Libby Hatch. Whereas "The Alienist" was told from the viewpoint of John Moore, a journalist for The New York Times, "The Angel of Darkness" is narrated by Stevie Taggart, one of the characters from that first book. Once the book actually gets going, however, it's first-rate, in particular the courtroom scenes with Clarence Darrow and the sections in which Stevie and Miss Howard (also from the first book) drive around upstate New York searching for information about the elusive Libby. Theodore Roosevelt makes a reappearance in this book as well although I thought his whole reason for getting involved in the case was a bit contrived. On the whole, however, it's a well-written and interesting book. Carr twice hints that the next book will be written from the perspective of the independent and energetic Sara Howard, which should be most interesting.
