Query: This is not a good book.

A prior reviewer's comment that this reads like at novel length research paper is entirely correct, and not even a good reaserch paper at that. For a much more interesting and informative look at early 19th century New York, I would highly recomment Gore Vidal's Burr. While it is written as fiction, much of the story (if not all of the dialog) is historically accuate and many of the figures who appear in the Murder of Helen Jewett cross the path of Burr in the novel.
