Query: Good book- kept me interested

The story in this book takes place during the late 1800s in New York City, back when several gangs of criminals fought for their turf. Ever see the movie "Gangs of New York"? You get the idea. One of the groups of criminals back then was called the "Whyos", and this fictional book is a story about how one man gets tied up in their criminal world. The story is interesting, the details of the time period are first-rate, and the characters have depth. I found this book for like a buck at a book-sale or something. Always fun when such a cheap book turns out to be such a good read.
