If you are referring to the original book
Donnie Brasco, the answer is yes - absolutely. And, if you haven't seen the movie version, I would say read the book first.
As far as
The Way of the Wiseguy, I know others may disagree with me somewhat, but I enjoyed it. Be advised, though, that the book is a rather quick read, and do not expect anywhere
near the substance of
Donnie Brasco. Even though it is informative, it really seems that Pistone just wrote the thing to make a quick dollar. I'm not sorry I read it, though. Also, truth be told, searching the Internet at sites like
BookFinder4U.com allowed me to save a
lot of money on these books.
Another book I'd recommend is
The Complete Idiot's Guide to the Mafia - Second Edition by Jerry Capeci. (I was able to find this online for around $5.00
including postage.) Excellent book, and the author's website
Gang Land is definitely worth checking out.
Now, regarding Pistone's new book
Donnie Brasco: Unfinished Business, it's just come out so I haven't gotten around to that one yet. There is a thread about it elsewhere in this very forum.
