Still about murder and mystery, but it's non-fiction. Murder and Mayhem in the Big Apple chronicles the rise of the BlackHand group to the downfall (that we know of) of its successor, the notorious Murder Incorporated. The author has certainly done his homework for this short true crime book, including many comments from the actual bad guys, and this is where this true crime book doesn't quite do it all for me. As interesting as the events are, there is a flatness to the end of the individual stories. It's not a big deal, but it is there to me.
There were so many names (good and bad and stupid) that it was hard to following the main story at times. With a bit more character portrayal, I don't think my mind would have wandered as much as it did. Still, if you are into the history of New York criminals, this is a great place for resource material.
