Picked up the Valachi Paper's for 50 cents at the local 2nd hand book op. shop bargain bin. 50 frickin' cents. Possibly the best half a dollar I ever spent. While I read this book years ago, having recently re-read I can see how it paved the way for mob lit. in general. As "coached" as he may have been on certain subjects, as overblown and ultimately low end as Valachi was, this is a great book. IMO, one of the best on the subject. Some may disagree, but however you look at it, Maas's book was a landmark in mob lit.
