TL;DR version: an after-the-fact account of how a man counterfeited millions all in the pursuit of "art". It makes for a romantic story, if nothing else -- although it certainly is not as sexy as the Leonardo DiCaprio/Tom Hanks Catch Me If You Can version.
The book by Frank Abagnale is a pageturner too. I've always liked reading those "social hacking" books, like Catch Me If You Can, or Kevin Mitnick's story The Art of Deception.
