A good book on the culture and mindset of the professional cheat but you will have to look elsewhere for specifics on the mechanics of the various sleights. I got this book 15 years ago and devoured it on my lunch break at the fast food joint I was working at. I venture forth trying desperately to discover the methods described within... These days you can find entire DVDs by Mr Ortiz showing these very moves in detail. Its a great time to be interested in gambling artifice.
