A fairly basic detective novel, the plot was interesting, but the characters could have been better developed.  Early plot twists felt a little flat to me and underdeveloped or rushed.  The villain was the most interesting character.  Certain areas rambled and the book could have been shorter to keep up the pace and give the reader that urge to keep turning the page.  The last portion of the book kept a good pace and was enjoyable.
Overall I enjoyed the book.
